Re-link fails on target "client_sharedlib while applying Grid Patch 29252164 (April CPU).

Hi All,

We are experienced a issue with April CPU Grid patch failing with below error when we were trying to apply on to Oracle Home.


==Following patches FAILED in apply:

Patch: /home/****/29252164/29176115/29141015

After fixing the cause of failure Run opatchauto resume

Further drill down issue by checking opatch log file and found below error.

[Jul 31, 2019 2:44:58 AM] [INFO]    8) OUI-67200:Make failed**** to invoke "/usr/bin/make -f ins_net_client.mk client_sharedlib ORACLE_HOME=/u02/app//**/db/tech_st/12.1.0"....'genclntsh: genclntsh: Could not locate /u02/app//**/db/tech_st/12.1.0/network/admin/shrept.lst

                                    make: *** [client_sharedlib] Error 1

Hence we created shrept.lst file at $ORACLE_HOME/network/admin

**Go to $ORACLE_HOME/network/admin

** Create file shrept.lst 

**Provide 644 permissions.

**Retry patching.

Thanks.
