Major diff between Oracle EBS R12.1.3 and Oracle EBS R12.2.4

 Major diff between Oracle EBS R12.1.3 and Oracle EBS R12.2.4


==> In R12.2 we have two kind of filesystems fs1(run filesystem) and fs2(patch filesystem) where as In R12.1.3 we only deal with one application filesystem.


==> In R12.2 we have the Application servers replaced by Weblogic server to manage the technology statck.

       The 10.1.3 Home is replaced by FMW i.e $FMW_HOME


==> In R12.2 is involvement of Weblogic server to manager all the forms,oacore servers.


==> In R12.1.3 we had the Application server 10.1.3 to manage the web home or Java Home.


==> The adpatch(patching) in R 12.1.3 is replaced by adop (online patching) in R 12.2.4


==> adop online patching utility doesn't require downtime. It involves minimal downtime during cutover phase where switching of filesystems happens. We can apply lot of patches and do cutover any time to minimize downtime


==> In adpatch we just apply patch most of the times by bringing down applications or in hot patch mode.


==> Apps user Password change: the 'apps' user password change involve 3 steps in R12.2.4


A) Change the password with FNDCPASS

B) Change the password in EBS Datasource from Weblogic admin console


Where as in R 12.1.3 It only involves 2 steps:


A)Change the password with FNDCPASS

B)Run Autoconfig


==> Log files locations: 

All the oacore,forms log files are placed in $EBS_DOMAIN_HOME in R12.2. 

Where as in R12.1.3 all the logs for oacore,forms are under $LOG_HOME/ora/10.1.3

AWR Reports

AWR Reports Introduction Workload Repository Reports AWR Snapshots and Baselines Moving AWR Information Reading the AWR Report Useful Queries Remove and Disable AWR Links with AWR Analyzer Introduction AWR periodically gathers and stores system activity and workload data which is then analyzed by ADDM. Every layer of Oracle is equipped with instrumentation that gathers information on workload which will then be used to make self-managing decisions. AWR is the place where this data is stored. AWR looks periodically at the system performance (by default every 60 minutes) and stores the information found (by default up to 7 days). AWR runs by default and Oracle states that it does not add a noticeable level of overhead. A new background server process (MMON) takes snapshots of the in-memory database statistics (much like STATSPACK) and stores this information in the repository. MMON also provides Oracle10G with a server initiated alert feature, which notifies database admini
