Switch OV Process Ownerships

In my-client implementation there is standard owner for OV processes, that is opc_op. We can check this on running agents/OV daemons via ps -ef | grep OV.

A non-standard my-client will return e.g. (which are owned by root):

root      2555     1  0 Mar10 ?        00:00:08 /opt/OV/bin/ovcd
root      2569  2555  0 Mar10 ?        00:00:08 /opt/OV/bin/ovbbccb -nodaemon
root      2597  2555  0 Mar10 ?        00:00:07 /opt/OV/lbin/perf/coda
root      2660  2555  0 Mar10 ?        00:00:00 /opt/OV/lbin/conf/ovconfd
root      2823  2555  0 Mar10 ?        00:00:16 /opt/OV/lbin/eaagt/opcmsga
root      2826  2555  0 Mar10 ?        00:00:00 /opt/OV/lbin/eaagt/opcacta
root      2840  2555  0 Mar10 ?        00:00:00 /opt/OV/lbin/eaagt/opcmsgi
root      8083  2660  0 18:17 ?        00:00:00 /bin/sh -c ps -f | grep OV
root      8085  8083  0 18:17 ?        00:00:00 grep OV

Hence, we’ll have to alter the processes ownership as follows:

[@node as root]

/opt/OV/bin/ovdeploy -inv  && ps -ef | grep OV  /opt/OV/bin/ovc -kill && ps -ef | grep OV umask 02 && /opt/OV/bin/ovswitchuser.sh -existinguser opc_op -existinggroup opcgrp \ && chmod 4550 /opt/OV/bin/ovbbccb && /opt/OV/bin/ovconfchg -ns bbc.cb -set CHROOT_PATH / && su - opc_op

The last line ($ su - opc_op) switch user to opc_op, so it’ll continue in this user:

[@node as opc_op]

 /opt/OV/bin/ovc -start && /opt/OV/bin/ovc -status

logIt » process owner
