Enterprise Manager 12c Cloud Control: What’s Changed, What’s New continued from page 11 Blackout Enhancements Oracle Enterprise Manager 12c offers a consolidated blackout information summary within the general region of a target’s home page. ASM Clusters as a Target An ASM Cluster in OEM 12c allows the management of an ASM cluster as a single target. What’s New? This section is all about what is new in Oracle Enterprise Manager 12c, detailing improvements and functionality repackaged and improved in such a way that it appears anew. Figure 26: Information Publisher Reports Metric Extensions Metric extensions allow full-fledged metrics to be created on targets. These are created and managed from the metrics extensions page as well as able to be export and imported between environments (Figure 27). BI Publisher Reports This is a feature that must be configured with Oracle Enterprise Manager 12c Cloud Control, as it is not configured by default. The Business Intelligence Publisher is an Oracle product that provides a powerful reporting tool for business intelligence environments. With Oracle Enterprise Manager 12c, the ability to integrate and utilize BI Publisher with OEM for reporting has been added. The only limitation at this time is that BI Publisher 11.1.1.5.0 is the only one that can be utilized. The BI Publisher 11.1.1.5.0 can be downloaded from the Oracle Technology Network at http://www.oracle.com/technetwork/ oem/grid-control/downloads/index.html. Database Auto Discovery One of the advantages of the new Oracle Enterprise Manager 12c is target discovery, where targets can be discovered automatically. OEM 12c Exadata server management has been improved through auto discovery of Exadata targets and simplified performance diagnostics more specific to Exadata. Backup and Recovery OEM 12c has also provided improvements in backup and recovery operations by allowing the central management of database and file system backups as well as uniform settings for both database and file system backups. Emergency Performance Oracle Enterprise Manager 12c introduces the use of the memory access mode to connect to a slow database. This allows the database administrator to troubleshoot the root cause of the problem. The memory access mode bypasses the SQL information retrieval layer and allows the reading of performance statistics directly from the SGA of the database. Compare Period Advisor Oracle Enterprise Manager can now compare the performance of a database over two different time ranges. OEM 12c analyzes changes in performance, workload, configuration and hardware and will highlight any changes found between the two provided time periods. Template Integration Monitoring templates and compliance standard settings and applying to targets and target groups has been streamlined. Page 12 ■ 1st Qtr 2013 Figure 27: Metric Extensions How do metric extensions really differ from user-defined metrics used in Grid Control? • User-defined metrics (UDM) collect values through executing OS scripts or SQL statements. This imposes several limitations: • UDM custom scripts/other files require file(s) to be manually placed on each target’s file system. • User-defined metrics collect multiple data pieces using multiple userdefined metrics and cannot refer to two data points from two metrics for alert generation, as data is collected separately. • User-defined metrics only use the OS script and SQL execution, while metric extensions can use protocols such as SNMP and JMX. • Only user-defined metrics are allowed for host targets and SQL for database targets. No other target types are allowed, such as WebLogic. Access Oracle Enterprise Manager 12c greatly improves overall security and access control. It incorporates fine-grained privileges through the introduction of 200 privileges from targets, objects and resources as well as new roles.
