How to discover multiple Oracle Databases in the same server Oracle Linux? – Troubleshooting


Hey everyone,

I have a problem when monitoring all the databases on my servers.
I will explain a little about the process I have done. I currently have two Oracle Linux servers and on each of them I have databases installed. The point is that, I already installed the checmk agent and discovered the services of each of the hosts… and it monitors network services, operating system… But, on a host it does recognize the databases to monitor but On host number two, only the Oracle SID of one database recognizes me and it does not recognize that of the other databases. When I try to log in to find out what the problem is, I get the following message:

Error message: [set_ora_env] ORA-99999 ORACLE_HOME for SID ‘pepito’ not found or not existing!

I already tried to set the ORACLE_HOME for each ORACLE_SID of the databases in: oratab (on linux /etc/oratab).

But, this didn’t work, can anyone help me with this problem?

CMK version: OMD – Open Monitoring Distribution Version 2.2.0p14.cce
OS version: Oracle Linux 7.9
