This is OEM 12cr2 for Oracle 11gr2 RAC env.
I have installed OEM 12cr2 and added all targets from 8 nodes (except the ASM instances are not prompted). the OEM works fine till today.
I have these setup on my host:
oracle_home is /oracle/OEM/1111
oms_home is /oracle/oms12cr2/oms
agent_home is /oracle/agent12cr2/agent_inst
1. I got an error when I log onto OEM: '/omsunavailable.html is unavailable, please contact system administrator'.
2. I go my OEM host to '.../oms12cr2/oms/bin emclt status oms', I got 'OEM configuration issue. /oracle/OEM/1111/<host_emrep> not find'
3. I could not find <host_emrep> any where on this host either this time.
4. what is Oracle_unqname and what it uses for?
I following your instruction on 12c installation and it worked. OS admin did change some user settings, but they would not delete any file. I would like to troubleshooting on it, seemed I have no clue so far.
Please let me know if you need more info from me. I will be very happy to find out and provide to you.
