- 8. R12.2 File system Layout 1. Two identical filesystems exist ( RUN & PATCH )to support Online patching feature 2. Single Non Editioned Filesystem that holds AD executables, PATCH_TOP and CM Log/Output files 3. Instance Top doesn’t hold Weblogic and OHS config files 4. Cannot do Readonly shared appltop across instances
- 9. Weblogic 1. Ships with both 64bit and 32bit Jrockit Java Runtime 2. Forms Managed Server JVM, CMs & AD utilities use 32bit jrockit 3. Rest all use 64bit jrockit 4. Known to use more memory than values set by Xmx & Xms

- 11. Installation Procedures This is a subtitle or bulleted list
- 12. Installation Procedures ■ Rapidwiz now shipped with RMAN backup instead of datafiles ■ It can now install directly onto a existing RAC cluster ■ Can also install onto to ASM ■ Cuts down build times of new instances ■ Default startCD installs JDK & JRE6 ■ Download new startCD to get JDK & JRE7
- 13. {Online} Patching This is a subtitle or bulleted list
- 14. Online Patching ■ Edition-Based-Redefinition (EBR) feature is used by R12.2 to enable online patching ■ New edition called PATCH edition is created during a patching cycle ■ Online users use the RUN Edition ■ Editioning Views enable new columns to be added during a patching cycle ■ Cross-Edition Triggers enable data changed by online users propagate to patch edition during a patching cycle
- 15. Online Patching Overview ■ Prepare ▪ Synchronizes patch edition and run edition on the file system. ▪ Creates a new patch edition in the database. ■ Apply ▪ Executes patch drivers to update patch edition. ▪ Patches applied: can be one or many, including customizations. ■ Finalize ▪ Compiles invalid objects. ▪ Generates derived objects. ■ Cutover ▪ Configures patch edition file system to be the new run edition file system. ▪ Configures patch edition of database to be the new run edition. ▪ Restarts application tier services. ■ Cleanup ▪ Delete obsolete code and seed data to recover space.
- 16. Online Patching ■ Applied using the new utility called adop ■ Patches need to copied to PATCH_TOP before applying ( $NE_BASE/EBSapps/patch ) ■ Adop can apply multiple patches in one go and has option to merge them before apply ■ Can apply patches directly to RUN edition using hotpatch option ■ Hotpatch option can be used to mimic old R12/11i kind of patching style adop phase=apply hotpatch=yes patches=xxx,yyy ■ Adop uses SID_patch service_name to connect to database
- 17. Online Patching contd. ■ Adop Connects to other nodes in multinodes setup via ssh and applies the patch ( similar to RAC patchings) ■ Fs_clone option clones the PATCH fs from RUN fs. ■ Mandatory to Keep AD & TXK patchsets at same level ■ AD patches are online, don’t need downtime. ■ $APPL_TOP_NE/ad/custom/adop_sync.drv is used to sync CUSTOM Code
