EBS R12.2 Discovery with OEM 13c

[Susmit]

Hi Erman,

We have a situation where EBS R12.2 is running with "applebs" user. Nut OEM agent and AMP plugin is installed with "oraagent" user. Both having "dba" as primary group.

We searched and found in 2045552.1,

OS/User Group Requirement
It is recommended that the primary OS group of both users should be same. If not, the primary group of the Oracle E-Business Suite user should be a secondary group of the agent user and the primary group of the agent user should be a secondary group of the Oracle E-Business Suite user.

But, it does not clarify exact permission needed in "Group". Like,in our case /apps1/r122/ebs is having permission 755. SO group os having 'r--x'. Hence "oragent" being part of "dba" group can only read and execute but not write. Is that enough? I don't get a reference for this. And OS admin team is refusing to give us "775" privileges.

good question.
not documented.

I don't exactly understand you mean.
you say we are using chmod 755, but you also say your OS admin team is refusing to give you "775"...

Bytheway, when you run autoconfig those permissions are reset ..
Some files are set to 755, and some files are set to 644, and some of them even set to 600.

I think you need to give this info to the OS Admin team.
EBS is a packaged application and it knows which permissions are needed for it..

There are permission related bugs documented for EBS 12.1 and AMP.
But your system is EBS 12.2

So what I recommend is, run autoconfig and then configure the group of your AMP OS user, as documented in note 2045552.1.

After that, check.
If you any encounter any issues, report it. (Create SR and also you can update me ..)

Hi Erman,

Autoconfig or EBS tools set its file permission as per need. We are not worried over it. The main concern for us is,
The group "dba" which is common for "applebs" and "oraagent" OS user, should this needed to have "write" privilege to EBS directories? During discovery is AMP try and write something in EBS directories? If not I think "755" will do else "775" is needed for <EBS Base Directory>.

Kindly help to understand.

755?
How do you find this magic number? :)

AMP is for EBS.
Oracle must have been calculated this.
Altough there may be issues during runtime, please do what the document says.
Don't play with the permissions.
Run autuconfig to have a clean start (in terms of permissions).
After that start running your AMP..
See if there are any permission errors.
If you see any filesytem related permission problem, we can concantrate on them.
but for now, do what the document says.
