Hi Eblyn Solis,
I install agent in client by user root:
# cd /setup/DP8/LOCAL_INSTALL/
# ./omnisetup.sh -IS
During install IS there are some message show: getnameinfo failed
Install process finish success, check installed by #rpm -qa OB2* look ok (please see attach screenshot)
In cell manager after add IS ctck-db, I add client ctck-db and check opion disk agent, media agent, oracle integration and process finish success.
I test backup file and intenal db also success.
As attach screen i sent before message, In my folder directory of cell manager C:\ProgramData\OmniBack\ don't have folder Config.
Cell manager and client I install version 7.0 first, and then upgrage to version 8.0, during install 7.0 and upgrate to 8.0 no error occur.
At verion 7.0 and 8.0 I get same error "Unable to browse instances" when config backup Oracle.
Best regards!
