Difference between Oracle EBS R12.1.3 and Oracle EBS R12.2.4


It's been a long time since I wrote a blog post, I was busy working with Oracle EBS upgrades,content server setup, and Oracle SOA 11g upgrade projects. We have recently upgraded Oracle EBS 12.1.3 to Oracle EBS R12.2.4.

There are lot of difference.Below are the key ones, I will try to extend this post based on difference noticed by me as I work more rigorously.

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

2)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  (Fusion Middleware Home) i.e $FMW_HOME

The major change in R12.2 is involvement of Weblogic server to manager all the forms,oacore servers
where as in R12.1.3 we had the Application server 10.1.3 to manage the web home or Java Home

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

adop(online patching) utility involves 5 phases to apply a standard patch in Oracle EBS R12.2.
adop involves 5 phases
1)prepare => prepare phase involves synchronization of the filesystems fs1 (run ,filesystem) and fs2(patch filesystem), filesystems are inter changeable.
2)apply=>In this phase we apply all the patches
Note: These patches need to be copied in fs_ne (non editioned filesystems)
3)finalize =>In this phase we are getting ready for cutover phase
4)cutover =>In cutover phase the filesystem switchover takes place. Previously the filesystem which was patch filesystem will now become run filesystem.)
5) cleanup =>In cleanup phase all the obsolute objects gets compiled .

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

where as in  adpatch we just apply patch most of the times by bringing down applications or in hot patch mode.

4)'Apps' user Password change:
The 'apps' user password change involve 3 steps in R12.2.4
1)Change the password with FNDCPASS
2)Change the password in EBS Datasource from Weblogic admin console
3)Run AutoconfigCheck below link from Bala for detail steps:


Where as in R 12.1.3 It only involves 2 steps:
1)Change the password with FNDCPASS
2)Run Autoconfig
5)Log files locations:
All the oacore,forms log files are placed in $EBS_DOMAIN_HOME in R12.2. I will explain this in details in my upcoming posts.
Where as in R12.1.3 all the logs for oacore,forms are under $LOG_HOME/ora/10.1.3

I will come up with lot of difference in this thread so that we all gets comfortable with Oracle EBS Release 12.2.4
 Happy Oracle Apps DBA reading and learning EBS R12.2.4...

Compressing the Oracle EBS TOPs and Uncompressing using tar and gzip

 Hi Apps DBA,

We usually do cloning by copying the Application tops from Source(TEST1) to Target(TEST2).
First we compress the files in source and than we copy those file from source to target and finally we uncompress followed by renaming and further process .Below are the useful commands and safe one to do this task.

Step 1:Tarring and zipping:

nohup tar -cvpf - ./test1appl 2> /u01/app/test1/test1appl.log | gzip -c -> /u01/app/test1/test1appl.gz &

nohup tar -cvpf - ./test1comn 2> /u01/app/test1/test1comn.log | gzip -c -> /u01/app/test1/test1comn.gz &

nohup tar -cvpf - ./test1ora 2> /u01/app/test1/test1ora.log | gzip -c -> /u01/app/test1/test1ora.gz &

Step 2:scp from source  to target:
Assuming we are on target server,we copy files from source to target as below:

scp -rp apptest1@uslaxorcap19:/u01/app/test1/*.tar.gz .


Step 3:Untarring and Unzipping:

nohup cat /u02/app/test2/test1appl.tar.gz|gunzip| tar xvf - >/u02/app/test2/test1appl.log &
nohup cat /u02/app/test2/test1comn.tar.gz|gunzip| tar xvf - >/u02/app/test2/test1comn.log &
nohup cat /u02/app/test2/test1ora.tar.gz|gunzip| tar xvf - >/u02/app/test2/test1ora_27Jun.log &

Note 1:Below command comes in single line in Unix shell prompt
Note 2:Advantage of above command is we can check logs and make sure the compressing and Uncompressing  is done successfully.

crsctl command to start and stop crs in Oracle RAC Database

Hi DBAs,

We basically have the below command to stop/start crs in Oracle RAC Database.

crsctl command to stop and start the cluster on a specific node noderac1 & noderac2:

We need to login with 'root' or specific sudo user having permissions to run the crs commands.

/u01/app/ stop crs
/u01/app/ disable crs

/u01/app/ enable crs
/u01/app/ start crs

where /u01/app/ =$GRID_HOME
crsctl command to stop and start on the Clusterware(noderac1 &noderac2) will be

/u01/app/ stop cluster -all
 /u01/app/ disable crs

/u01/app/ enable crs
/u01/app/ start resource -all

where /u01/app/ =$GRID_HOME

How to check Pre-requistics Patches while applying Database Patch using opatch

Hi DBAs,

Lot of time we apply Database patches using the opatch,It is mandatory to know the Pre-requistics patches for applying the Patch.We can find it out with the below steps.

Step 1:Go to the Directory where patch is copied(PATCH TOP)
>cd /home/oracle/patch/18308717

Step 2:Execute below command
>$ORACLE_HOME/OPatch/opatch prereq CheckConflictAgainstOHWithDetail -ph ./
