Opatch or Mopatch needs to modify some files which are still being used by some process. As you see one of the Oracle library is still active.
Find out the process which is still actively using the library /oracle/RACP/112_64/lib/libclntsh.so.11.1 and kill or stop the process.
$ /sbin/fuser /oracle/RACP/112_64/lib/libclntsh.so.11.1
$ ps –ef |grep 9785
oraracp 9785 1 0 Jul24 ? 00:02:39 /oracle/RACP/112_64/bin/tnslsnr LISTENER_RACP -inherit
oraracp 19813 7919 0 17:25 pts/2 00:00:00 grep 9785
$ lsnrctl stop LISTENER_RACP
$ kill -9 9785
The listener process is still running and causing the issue. We have stopped the listener process and reapplied the patch successfully.
