Not All Endpoints Registered

If issuing “crsctl status resource” command show the status of listener as “Not All Endpoints Registered”, it is usually because of contradictions in the Listener settings. It means that probably you have a manually setup listener (by editing listener.ora file) with different settings than registered with the CRS/HAS. Or, there could be multiple listeners configured from multiple oracle homes – one from Grid Infrastructure home, and other listener with same configuration running from other home and started manually (using lsnrctl command).

Initialization parameter setting back to original value

I faced a very strange situation whereby I was setting my log_archive_dest_1 parameter using ALTER SYSTEM command with SCOPE=BOTH, which meant that this parameter value change should have been consistent across the instances reboot as this change was also being made in the spfile (SPFILE was in use for that database/instance) as well as in memory. However, it was not happening actually. After every instance restart, the value of this parameter would again set to the old value and this was causing problems for us.
