Hi Carol,
You can check the version and patch level with the ObjectServer version tool i.e. nco_id.
Netcool/OMNIbus information about collecting installation details with the ObjectServer version tool (nco_id) is available in the IBM Knowledge Center (KC). Information about command line options for the tool is also included. See this KC link,
