- 8. Benefits of Multitenant Manage Many Databases As One – Patch and upgrade one multitenant container database Increase server utilization – High density database consolidation per server Backup many database as one – Backup one multitenant container database Provision Databases Rapidly – Single step to clone database instantly Move Database rapidly – Easy to move database (UnPlug&Plug) Dynamic resource management between pluggable databases. 10/01/138 Courtesy by Oracle.com
- 10. Recovery Manager and Data Pump Recovery Manager 12c – Pluggable Database-level Recovery RECOVER PLUGGABLE DATABASE – Retrieve point-in-time version of table(s) with RECOVER TABLE – Cross-Platform Backup and Recovery BACKUP TO PLATFORM … RESTORE FROM PLATFORM … Data Pump 12c – NOLOGGING on duration of import with IMPDP 10/01/1310 >IMPDP … TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y …>IMPDP … TRANSFORM=DISABLE_ARCHIVE_LOGGING:Y …
- 11. 10/01/1311 Oracle Data Guard 12c
- 12. FAST SYNC SYNC NOAFFIRM with Maximum Availability Mode – Fast Sync provides an easy way of improving performance in synchronous zero data loss configurations also allows a standby to acknowledge the primary database as soon as it receives redo in memory, without waiting for disk I/O to a standby redo log file. 10/01/1312 Courtesy by Oracle Documentation Library
- 13. FAR SYNC Far Sync instance is like a little cascading destination standby database. Far Sync instance is not have any data files A Far Sync instance manages a control file, receives redo into standby redo logs (SRLs) 10/01/1313 Courtesy by OOW Presentation
- 14. 10/01/1314 Oracle Real Application Clusters and Grid Infrastructure
- 15. Flex Cluster 12c Cluster – Traditional and Flex Cluster Hub nodes and Leaf nodes – Multiple Leaf nodes can use single Hub node – Hub nodes have direct access to OCR/Voting disks – Flex ASM required for Flex Cluster 10/01/1315 $ ./crsctl get cluster mode status$ ./crsctl get cluster mode status
- 16. Flex ASM Oracle Clusterware automatically starts surviving ASM Instance on different node, when ASM Instance Failed on a Node Load balancing capabilities for the instances running on the nodes 10/01/1316 Courtesy by Oracle Technical Articles
- 17. Additional new features Tuning ASM rebalance operations – EXPLAIN WORK FOR operation and V$ASM_ESTIMATE view ASM Disk Scrubbing V$ACTIVE_SESSION_HISTORY view for ASM instance Increased ASM Storage limits – Support 511 ASM Disk group, ASM disk can be 32PB OCR can be backed-up in ASM Disk group 10/01/1317 SQL> ALTER DISGROUP DATA SCRUB POWER LOW:HIGH:AUTO:MAX;SQL> ALTER DISGROUP DATA SCRUB POWER LOW:HIGH:AUTO:MAX; $ ./ocrconfig –backuploc +DATA;$ ./ocrconfig –backuploc +DATA;
