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 doesnt hold Weblogic and OHS config files 4. Cannot do Readonly shared appltop across instances 11. 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 12.

Installation Procedures This is a subtitle or bulleted list 14. 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 15. {Online} Patching This is a subtitle or bulleted list 16. 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 17. 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. 18. 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 19. 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, dont need downtime. $APPL_TOP_NE/ad/custom/adop_sync.drv is used to sync CUSTOM Code 20.
