Services enable you to model and deploy both planned and unplanned operations for all types of high availability or disaster recovery scenarios. Just as Enterprise Manager monitoring identifies problem areas in your database and database groups, you can administer your database using the Enterprise Manager administration tools. A post-processing function has the same signature as a user-defined function, but passes in the mask value the masking engine generates, and returns the mask value that should be used for masking, as shown in the following example: rowid is the min (rowid) of the rows that contain the value mask_value. For example, you can use Enterprise Manager to manage the memory size of the system global area and program global area of your system. Database management involves the monitoring, administration, and maintenance of the databases and database groups in your enterprise. Before creating a masking definition, be aware of the following advisory information: Make sure the format you select does not violate check constraints and does not break any applications that use the data. Clone the production database to a staging area, selecting the masking definition to be used after cloning. The library consists of format routines that you can use for masking. Perform post-processing on the above-generated value to ensure that the final result is a valid, realistic value. If you clicked Define Format and Add in the previous step and did not check "Mask selected columns as a group," .... ... the Define Column Mask page appears, where you can define the format for the column before adding the column to the Create Masking Definition page. Masked data is a sensible precaution from a business security standpoint, because masked test information can help prevent accidental data escapes. Baselines are stored internally in the Enterprise Manager repository, and are in a form that other Change Management applications can use. The Topology Viewer allows you to view the relationships between components, nodes, or objects within different Oracle applications. Similar to other format definitions, you can affect the "style" of the ISBN format by setting values to DM_ISBN_FORMAT. The MAA Advisor page contains a table that lists the Outage Type, Oracle Solution, Recommendation Level, Configuration Status, and Benefits. The Dependencies table shows you the Object Name and the Object Type that is dependent on the current view. The Databases page appears. SELECT ANY TABLE 4. You can also view the content of the audit trail. Concurrent read and write activity on shared data in a cluster occurs frequently. Note the references to other sections for supporting information. If objects are layered on top of a table such as views, materialized views, and PL/SQL packages, they are recompiled to be valid. A dictionary comparison identifies differences in database object definitions between two databases, a database and a baseline, or two schemas within a single database/baseline. Oracle Database Management is database management software. Specify a required database name. With Enterprise Manager, you can compare, view, and track differences between two sets of database object definitions at different points in time. Resource plans specify the resource consumer groups belonging to the plan and contain directives for how resources are to be allocated among these groups. The result of any SQL query can be automatically converted into an XML document. Enterprise Manager lets you compare these configurations to determine differences between two or more hosts, clients or databases. As an administrator, you can use the administration tools in Oracle Enterprise Manager to optimize database performance. To use the predefined masking formats on a target database (other than the repository database), you must manually install the DM_FMTLIB package on that database. – Low-cost, subscription-based database cloud service with per-second consumption-based billing lowers costs, – Securely deployed behind customer data center firewalls, – Available with Oracle Autonomous Database or Oracle Database Enterprise Edition, – 8X scaling with four high-performance shapes managed by Oracle to match customer business needs, – Up to 7X larger databases than RDS on AWS Outposts for efficient consolidation of customer databases, – Up to 12X more SQL IOPS to shared storage than RDS on AWS Outposts, so analytical applications run as fast as possible, – Up to 10X more SQL throughput to shared storage than RDS on AWS Outposts accelerates customer data warehouses, – Up 98% lower SQL latency to shared storage than RDS on AWS Outposts makes crucial customer OLTP applications more responsive. The charts on the Database Performance page display current and recent metric information on a common time axis that enables visual correlation of metrics. If the columns being masked are involved in unique, primary key, or foreign key constraints, data masking generates the values so that the constraints are not violated. The run queue length indicates the level of contention for CPU time. If a primary instance fails, Oracle moves the service from the failed instance to a surviving alternate instance. This format is capable of generating 10 billion unique credit card numbers. This requires knowledge of the application schema. The most direct method for investigating and diagnosing performance problems from this page consists of accessing the Automatic Database Diagnostic Monitor (ADDM). The Explain Materialized View feature helps you to determine what is possible with a materialized view by indicating whether a materialized view is fast-refreshable, what types of query rewrites you can perform with this materialized view, and whether PCT refresh is possible. An Oracle Certified Specialist is more specialized and focuses on implementation. The Database field shows the database name of the database target you selected before accessing the Data Masking Definitions Page. In addition to viewing, editing, and deleting these structures, you can also perform other functions such as making tablespaces locally managed, displaying the dependencies of a datafile, or backing up a control file to a trace. Flashback database lets you quickly recover an Oracle Database to a previous time to correct problems caused by logical data corruptions or user errors. In many cases, masked data is a legal obligation. See "Adding Dependent Columns" for more information. Data management is at the heart of fundamental trends now transforming how businesses use technology. Oracle Exadata Cloud@Customer combines the performance of Oracle Exadata with the simplicity, flexibility, and affordability of a managed database service in customer data centers. Oracle database management Put your DBAs in the driverâs seat with Oracle database management tools. For example, if you set this variable to '-', the typical social security number would appear as '123-45-6789'. A DBMS serves as an interface between the database and its end users or programs, allowing users to retrieve, update, and manage ⦠For instance, a user-defined function to mask a number could receive 100 as input, the string representation of the number 100, and return 99, the string representation of the number 99. Oracle Enterprise Manager uses the Scheduler to enable database administrators and application developers to control when and where various tasks occur in the database environment. Create a new masking definition based on a previously created masking definition that is then applied to a new database. Each restore point has a name and creation time. Media recovery using Enterprise Manager can be either complete recovery or point-in-time recovery. Masking assumes it should perform the masking to honor these additional constraints. MySQL Database Service enables organizations to rapidly and securely deploy modern, cloud native applications using the world’s most popular open source database. After you have done this, you can use the predefined masking formats in your masking definition. However, you can also use the Administration section of the page to perform common administration tasks such as the following: Allocating system storage and planning future storage requirements for the database system, Creating and managing primary database storage structures (tablespaces), Creating and managing primary objects (tables, views, indexes), Enrolling users and maintaining system security by controlling and monitoring user access to the database. In general, advisors produce more comprehensive recommendations than alerts, since alert generation is intended to be low cost and have minimal impact on performance. Deleting obsolete backups from the repository and from disk. The Oracle database management software can help identify root causes of bottlenecks, providing diagnoses and recommendations. Database Control is installed and available with every Oracle Database 10g installation. Both aggregate and instance-specific performance statistics are displayed using color-coded charts for easier viewing. The legal requirements vary from country to country, but most countries now have regulations of some form to protect the confidentiality and integrity of personal consumer information. Materialized views can be refreshed either on demand or at regular time intervals. Select the table columns as well as the appropriate mask formats. Sometimes, you can immediately identify interconnect delays due to applications outside the Oracle Database. A complete set of integrated features for managing Oracle Databases, Unparalleled scalability that lets you manage a single database or thousands of instances, An intuitive management product that leads the industry in ease of deployment and use. Figure 5-7 Automatic Database Diagnostic Monitor Page. You can use the Database Maximum Availability Architecture (MAA) Advisor page to view recommended Oracle solutions for each outage type (computer failures, storage failures, human errors, data corruptions, and site failures), view configuration status and Enterprise Manager links for each solution, and view the benefits for each of the solutions that are offered. You can use these statistics to automatically set metric thresholds for alerts, as well as to normalize graphical displays of system performance. 2. Database administrators can schedule and monitor recurring database maintenance jobs, such as backups or nightly data warehousing loads and extracts, and they can schedule job execution based on time or events. Normally, if a system is slow or in a hung state, the diagnostic queries are also either extremely slow or never return a result. You can use Enterprise Manager to capture the database object definitions at a particular point in time and create reusable baseline scope specifications. The Clone Database wizard appears, where you can create a test system to run the mask. Recognition from Gartner further validates the business and technology breakthroughs of Oracle Autonomous Database. For instance, if you search for social security numbers (SSN) and this yields 100 SSN columns, you could select them all, then click Define Format and Add to import the SSN format for all of them. 3,111 Oracle Database Manager jobs available on Indeed.com. The following prerequisites apply for the column to be defined as dependent: A valid dependent column should not already be included for masking. Otherwise, a failure occurs when the job runs. The Session Details page, shown in Figure 5–5, displays the wait events associated with the session you selected in the Active Sessions Waiting page. Oracle Patch Advisories describe critical software patches for Oracle products. SEL⦠You can use the Automatic Workload Repository to change the snapshot interval, ranging from 10 minutes to 2 hours. Oracle Database is commonly referred to as Oracle RDBMS or simply Oracle. Oracle provides customers with a range of database engines and deployment choices so customers can deploy their workloads wherever required. A page appears that enables you to provide input for the format entry you have selected. When cloning the database to an external or unsecured site, you should use Export or Import, and only supply the data in the database rather than the database files themselves. Oracle Autonomous Database is an all-in-one cloud database solution for data marts, data lakes, operational reporting, and batch data processing. The following sections discuss these diagnostic pages: The Top Consumers link provides global summary information for the top database consumers of system resources. Figure 5-8 Top Consumers Top Modules Page. Using information from this page, you can cancel the problem session and return the system to its normal state. Make them proactive by giving them deeper insight into critical systems, both on-premises and in the cloud, so they can identify performance issues in record time, resolve them 10 times faster and minimize the impact of database changes. Use the tools in Oracle Enterprise Manager to set up and manage your Oracle Streams environment. For instance, if you click User I/O, the Active Sessions Waiting: User I/O page appears, as shown in Figure 5–3. Database Control is the Enterprise Manager Web-based application for managing Oracle Database 10g Release 2 (10.2). Data masking can modify sensitive database records so that they remain usable, but contain no confidential or personally identifiable information. Use synonyms for the keyword you typed, for example, try “application” instead of “software.”. After masking, test all of your applications, reports, and business processes to ensure they are functional. You can perform all the patching activities from the Patch Cache. The Define Format and Add feature can save you significant time. A role can be created by users, usually administrators, and is used to group together privileges and other roles. Select one of the available format types. Using the format library, you can generate either 10-digit or 13-digit ISBN numbers. When done, provide an optional user-defined or post-processing function (see "Providing User-defined and Post-processing Functions"), then click OK to save the masking format. For example, in the United States, The Right to Financial Privacy Act of 1978 creates statutory Fourth Amendment protection for financial records, and a host of individual state laws require this. Wait class drill-downs enable you to investigate a specific wait class where it appears that time is accumulating. This chapter introduces the concept of database management in the following sections: Masking Sensitive Data for Non-production Use, Monitoring Oracle Real Application Clusters. Either select one or more columns for formatting later on the Create Masking Definition page, or formatting now if the data types of the columns you have selected are identical. This chart is the centerpiece of Oracle performance monitoring, and shows potential problems inside the database. After cloning, be sure to change the passwords as well as update or disable any database links, streams, or references to external data sources. During masking, Enterprise Manager automatically drops these temporary tables for you with the default "Drop temporary tables created during masking" option. You can use the High Availability Console page to display high availability events, view the availability summary that includes the status of the database, view the last backup status, view the Flash Recovery Area Usage, view the Data Guard summary, and view the RAC Services summary including Top Services. You can use this page to monitor the interconnect interfaces, determine configuration issues, and identify transfer rate-related issues, such as excess traffic. Proceed through the wizard steps as you ordinarily would to clone a database. Oracle is often used by global enterprises, which manage and process data across wide and local area networks. Scripting on this page enhances content navigation, but does not change the content in any way. Enterprise Manager's physical backup and recovery features are built on Oracle's Recovery Manager (RMAN) command-line client. Global Cache Block Transfer Rate shows the total aggregated number of data blocks received by all instances in the cluster through an interconnect. Both of these options provide high performance and cost-efficient pricing. They are suitable in various computing environments such as data warehousing, decision support, and distributed or mobile computing. See "Data Masking Task Sequence" for more information. Oracle Database solutions support customersâ most business-critical apps and keep their data safe. Oracle Real Application Clusters (RAC) provides a high-availability database environment spanning multiple hosts. The wait class drill-downs are called Active Sessions Waiting pages. In addition to containing resource consumer groups, a plan can contain subplans. Click OK to save your definition and return to the Data Masking Definitions page. The Maximum CPU line on the chart helps determine how much of the CPU resource is being utilized. The information security administrator reviews the masking definition, verifies its completeness, then recommends that the application database administrator proceed with the masking process. Data Masking does not support clustered tables, masking information in object tables, XML tables, and virtual columns. Oracle Database has its networking stack that allows application from a different platform to communicate with the Oracle Database smoothly. This Oracle Database 12c R2: Clusterware Administration training will explore general cluster concepts and Oracle Clusterware architecture. Block media recovery is a technique for restoring and recovering individual data blocks while all database files remain online and available. Session wait time accumulates above the CPU line, and the ratio of wait time to CPU time indicates how efficiently the system is working. Starting from the Database Home page, you can access additional details and management functions by drilling down through the user interface. Enterprise Manager provides two separate consoles that you can use to monitor your database: Database Control and Grid Control. ASM internally creates, deletes and manages files as and when needed using the storage space from the disk groups. Some advisors also provide what-if analysis for specific situations. Migration from on-premises Oracle Database to Amazon RDS for Oracle is quick because [â¦] Learn more about training and certification you can rely on to ensure your organization's success. After the masking process is complete, you can distribute the database for wide availability. You can clone the production database to a mask staging area, then make the staging area the new test region. Besides the primary diagnostic pages discussed above, there are other important secondary pages that can assist you in diagnosing and correcting performance problems. For complete information on the format types, see the online help. Database files are automatically distributed across all available disks, and database storage is rebalanced whenever the storage configuration changes. The system responds by validating the mask template and creating a masking definition based on the template. The system responds by adding these table columns as dependent columns to the masking definition. The cloned database should be controlled with the same privileges as the production system since it still contains sensitive production data. Oracle RAC uses the voting disk to determine which instances are members of a cluster. These are valid, realistic looking numbers than can pass standard phone number validation tests employed by applications. Data Guard provides a comprehensive set of services that create, maintain, manage, and monitor one or more standby databases to enable production Oracle Databases to survive disasters and data corruptions. The voting disk manages cluster membership by using a health check, and arbitrates cluster ownership among the instances in case of network failures. Quest Toad is a database management software tool and code optimization ⦠An RDBMS that implements object-oriented features such as user-defined types, inheritance, and polymorphism is called an object-relational database management system (ORDBMS). Oracle uses machine learning to completely automate all routine database tasks—ensuring higher performance, reliability, security, and operational efficiency. Oracle backups to disk can be saved as image copies or backup sets. To install the DM_FMTLIB package, see "Installing the DM_FMTLIB Package" . For more information about these features, see Change Management for Databases. Note that you can perform cloning using Enterprise Manager, which enables you to add masking to the Enterprise Manager clone workflow. You can alternatively investigate all wait classes in one location and then drill down from there. Figure 5-14 shows an example of user input. The credit card numbers generated by these format pass the standard credit card validation tests by the applications, thereby making them appear like valid credit card numbers. Each version has a unique version number and a synchronization date. From this page, you can display an overview of your database properties and performance. Some competitor software products to Oracle Database Management include Knack, InterScale Scales Manager, and Help Desk Migration. The mask formats may be simple or complex depending on the information security needs of the organization. Out of the box, you can generate valid U.S. social security (SSN) numbers. The data type and uniqueness of the output values must be compatible with the original output values. Using the Scheduler helps to improve the management and planning of these tasks. Oracle Exadata is highly available and highly performant; it’s the most secure architecture for running Oracle Database. As a matter of best practice, organizations should create masking formats for all common regulated information so that they can be applied to the sensitive data regardless of which database the sensitive data resides in. An Oracle Database consists of a database and at least one instance. This is important when the test and production sites reside on different Oracle Management Systems or reside on entirely different sites. The following types of users participate in the data masking process for a typical enterprise: Application database administrator or application developer. Database tuning is much easier and more effective when all the information for an in-depth performance diagnosis is available on a single screen. Oracle maintains the data in materialized views by refreshing them after changes are made to their master tables. Oracle Database has extended the relational model to an object-relational model, making it possible to store complex business models in a relational database. A Data Guard configuration consists of one production database and one or more standby databases. Conversely, you can use Enterprise Manager to import the contents of a database, objects, and tables. Create a masking definition to associate table columns to these mask formats. When you have finished formatting the column, click OK to return to the Create Masking Definition page. However, if you are retaining the masked data in-house, see the next section. Enterprise Manager allows you to manage program structures, such as packages, package bodies, functions, and triggers in the same way. It can be provisioned on bare metal servers (with local NVMe flash or SSD storage) or virtual machines with block volumes. You can use the transportable tablespaces feature to move a subset of an Oracle Database and plug it in to another Oracle Database, essentially moving tablespaces between the databases. If one cluster host fails or is taken offline, the other hosts of the cluster continue operating, and the entire Oracle RAC database remains available for applications. You can also use the Undo Management feature to provide a means of explicitly specifying the amount of undo information to retain and ensure that undo information is not overwritten. Enterprise Manager's flashback features provide a range of physical and logical data recovery tools as efficient, easy-to-use alternatives to physical and logical backups. In addition to creating, deleting, and managing views, you can also view the objects that are dependencies of the view. You can flash back the database to a restore point if the required flashback logs and archived logs exist. This means that two or more computers with typical performance appear to applications as if they were a much more powerful computer.To increase performance, availability, and reliability of a two-host Oracle RAC database, you can add cluster hosts. Using these tools, you can manage storage structures such as control files, tablespaces, datafiles, and archive logs. Here are the integration benefits of the Oracle Database: 1. Originally developed in 1977 by Lawrence Ellison and other developers, Oracle DB is one of the most trusted and widely-used relational database engines. This is the most secure approach. Figure 5-8 shows the Top Modules page of Top Consumers, where you can perform tasks such as enabling and disabling aggregation and SQL traces for the consumer. As with the Active Sessions Waiting pages, look for skewed activity for either Top SQL or Top Sessions. Oracle Database Cloud Service allows you to create and manage full-featured Oracle Database systems in the cloud. Run analytics on all data types with Oracle’s single converged database engine. By specifying the configuration of the elements acting on the stream, you can address specific requirements, such as message queuing or data replication. Click the Data Masking Format Library link. Statistics are computed over the baseline period for specific target metrics. The following sections discuss these tools: Enterprise Manager provides a Topology Viewer for several applications. Enterprise Manager is the premier tool for managing your database environment. If you clicked Define Format and Add in the previous step and checked "Mask selected columns as a group," .... ... the Define Group Mask page appears, where you can add format entries for group columns that appear in the Create Masking Definition page. For more information about the various functions available for a specific object, you can refer to the online Help. Either click Add to add the column to the masking definition, return to the Create Masking Definition page, and define the format of the column later, or click Define Format and Add to define the format for the column now. You can change the state of a job by suspending it, canceling it, or resuming it if it had previously been suspended. This enables SSMA to obtain metadata from schemas owned by the connecting user. Backups to tape and similar media management devices must be stored as backup sets. That is, the last digit of any credit card number is a checksum digit, which is always computed. Select one or more column names from the list that appears below, then click Add. You can also increase the number of threads dedicated to the job and thus increase its resources.
