Cause

The issue is associated with WLST creating temporary packages under

/tmp/wlstTemporacle/packages

and those packages may be corrupted.

Solution

Stop oms with command,

    emctl stop oms -all

Then, remove following temporary directories,

  /tmp/wlstOfflineLogs_oracle

  /tmp/wlstTemporacle

Start oms with command,

    emctl start oms
