CAUSE:

VCS Oracle and Netlsnr agents relies onthe user information of the Oracle resource owner in VCS configuration to successfully monitor VCS resources. VCS Application agent's monitor entry point runs '/usr/bin/id' command as resource owner in Solaris zone context, i.e, runs"zlogin /usr/bin/id " command from global zone as root. In one situation, this command was failing occasionally due to SUN bug (doc # 6815860 - zlogin(1) needs to be largefile safe). If the'/usr/bin/id' command fails to complete, VCS would return the resource state as UNKNOWN but would continue to work normally.


SOLUTION:

Please contact SUN/Oracle support to address the SUN bug (doc # 6815860 - zlogin(1) needs to be largefilesafe) issue. No changes is required from VCS side.
