Oracle Applications R12.2.5 New Features: dualfs in cloning


From Oracle Applications Release 12.2.5 Version, we have dualfs option for cloning applications tier.We can use this feature in earlier 12.2.x versions also, if AD-TXK Delta 7 patch is applied.Before AD-TXK Delta 7, it was required to run adcfgclone twice on run and patch filesystems.Using dualfs option,we can create both run and patch fs at one time.

-bash$ perl adcfgclone.pl appsTier dualfs

What are the differences between Oracle Applications R12.1.x and R12.2.x

From DBA perspective, below are the changes in R12.2.x version of Oracle Applications, compared to R12.1.3.


1. Dual FS: Oracle Application Release 12.2 has dual filesystems(RUN FS and PATCH FS) to facilitate Online Patching.This Requires double the mountpoint space at MiddleTier Level.

2. Weblogic Server: Oracle HTTP Server in R12.1 is replaced by Oracle Weblogic Server.
10.1.3 Home is replaced by FMW_HOME.Weblogic Server Manages all oacore, forms and oafm servers in R12.2.

3. Online Patching : Dual Filesystem and EBR feature in 11gR2 Database facilitate online patching. Online Patching minimizes the downtime required for patching.adpatch utility in R12.1.x is replaced by adop utility. adop cycle runs in 5 Phases : prepare,apply,finalize,cutover and cleanup. adop internally calls adpatch utility to run the driver files associated with adop phases.

4. APPS Password Change: After Changing Apps Password in R12.2, we need to update the new password in EBS Datasource used by Weblogic Domain.To know more about apps password change in Oracle applications R12.2, check the below link.


5. Cloning : While Cloning of R12.2.x adcfgclone instance needs to be run twice,  on RUN fs and PATCH fs.From 12.2.5 Version (OR R12.AD-TXK Delta 7), we have the dualfs option which creates both run fs and patch fs during clone process.

How to Configure RMAN Backups into Multiple Locations?

If we need  RMAN to distribute backup sets among multiple disks on different mountpoints. We can use the below syntax to configure backup in multiple locations.

Using Allocate Channel:

RUN
{
ALLOCATE CHANNEL c1 DEVICE TYPE DISK FORMAT '/u01/oracle/data1'; 
ALLOCATE CHANNEL c2 DEVICE TYPE DISK FORMAT '/u02/oracle/data2'; 
}

Using Configure Channel:

CONFIGURE CHANNEL DEVICE TYPE DISK FORMAT '/u01/%U', '/u02/%U';
