Nagios Support Forum

We recently installed the Oracle Client/etc software on our Nagios XI system, so we can monitor our Oracle databases. When trying to use one of the wizards, received the following:

CRITICAL - cannot connect to server1:1521/db1. install_driver(Oracle) failed: Can't load '/usr/local/lib64/perl5/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.18.1: cannot open shared object file: No such file or direct

We are running Nagios XI on CentOS 6. We had trouble getting the latest version of the Oracle software working (19.3), so we uninstalled the 19.3 RPMs, and instead used the 18.5 RPMs.

Hello @mblower,

This looks like a path error on the system. Please post the output of the following command. Also, we have some troubleshooting tips ( See Common Problems) in the documentation.

How To Install & Configure The Oracle Client & Plugins

That file had the wrong path, it had 19.3, which was removed during troubleshooting, and 18.5 was installed instead. I have updated the file. Do I need to restart Nagios or anything to have the change go in to effect?

Thanks.

Looks like I spoke too soon, it's working now (sort of). We must have a firewall issue, because now it is saying it can't connect. I think you can close this issue, thank you for the help.

No problem. Good to hear it's working now.
