RE: Linux ps command

Thanks for everyone's suggestions. Unfortunately no luck yet but I think that's because I'm looking in the wrong place focusing on 'ps' itself. I have discovered two further things:  

  1. ps works fine, as expected if I start the instance from the unix user oracle, but I get this "[oracle]" behaviour if I start it from any other user, ie. members of the dba group.
  2. /proc/<pid>/cmdline is empty if the instance is started by a non-oracle dba group member.

It looks like the process just isn't being registered properly with the Linux kernel correctly at start up, so I can't blame ps for not being able to report on it. Not sure why that is - the suid and guid bits are set ok on the oracle binary. I guess I'll just have to start the instance as oracle for the time being.  

Any further suggestions welcome.

export PS_PERSONALITY=sun
export CMD_ENV=sun

then run the usual SunOS commands "ps -ef | grep ora"

Thanks, but sorry, no - this returns "[oracle]" again:

See if it give you want you require.

try ps auxc

a = all processes on a terminal, including other users
u = display user-oriented format
x = select processes without controlling ttys
c = display true command name

Subject: Linux ps command

Hi List,

If I run "ps" on Solaris or on SuSE Linux 7.2 I see the Oracle background processes under the command heading containing the SID, eg. "ora_smon_MYSID" or "oracleMYSID (LOCAL=NO)". If I do the same under SuSE Linux 8.2 I just get "[oracle]", no process name and no SID.

I know I can cross-reference process id's with V$PROCESS but it's a lot easier if this information is already in ps. Is there some way to get SuSE 8.2 to behave like 7.2 (or Solaris) in this regard?

Thanks
- Charlotte
