Opatch reports 'Cyclic Dependency Detected' error when patching ODI 

Issue:

When applying a Patch Set Update (PSU) to WebLogic Server 12.2.1.3 on Linux platforms, it fails with "ApplySession::apply failed: oracle.glcm.opatch.common.api.install.HomeOperationsException"

Error:

java.lang.RuntimeException: ApplySession failed in system modification phase... 'ApplySession::apply failed: oracle.glcm.opatch.common.api.install.HomeOperationsException: A failure occurred while processing patch: <PATCH_ID>'

Cause:

The Linux 'ulimit' open process limit may be set too low.

Resolution:

We need to add user limits in /etc/security/limits.conf file as root user

vi /etc/security/limits.conf

*          soft    nproc           65536

*          hard    nproc           65536

*          soft    nofile          65536

*          hard    nofile          65536

Note: "*" represents all users, if you want to add limits for specific user replace "*" with user name.

Example:

oracle          soft    nproc           65536

oracle          hard    nproc           65536

oracle          soft    nofile          65536

oracle          hard    nofile          65536
