OPC_OP group what is it

Can someone explain to me what the ID and group OPC_OP is and why it has taken over an UID already in use?

thanks

Re: OPC_OP group what is it

This is likely related to the HP Openview Operations Center (OPC) product.  During installation it adds user ids and groups to the system.  I believe there are several all starting with opc_ (opc_adm, opc_op, possibly others).

 

Apparently it did not check to see if the UID was already in use when it added opc_op.

Re: OPC_OP group what is it

You probably can.  I would make a list of all files owned by the opc_op id (use find), stop any OPC processes that are running, change the UID, change all of the files to be owned by the new UID, and then restart the OPC processes.

Re: OPC_OP group what is it

from HP SelfSolve, i found this:

By default opc_op will use user ID (UID) 777 and group ID (GID) 77 when this account is created on a UNIX system.  However, if these are already taken then they will find the next available number.

 

but, this was in OpenView OVO6x - during 2002. presently its OM9x. but i think the UID and GID numbers are not changed even on OM9x(i dont have access to any OM9x, othervise, i could have verified this).

 

when i searched for how to change the UID and GID, i dont see any document which says we should not change the UID, GID's. So, you can change it, i think.
