I need to check with nagios an oracle database that is located on a server.
There are a lot of plugins that are provided, but can someone pls help me with this? the problem is that the database is located on a remote server (i have an hostaddress) and then i need to log on the database (i have username and pass)
So i only need to have a plugin that connects to that hostaddress and logs on, but i can't find any plugin which does that..?!
Can someone help me, i'm not familiar with this (database and etc.)
I've set this up almost a year ago so might be missing some points in my explanation. As I recall it, you'll need to install the Oracle client for the version of your Oracle database server. That will provide you with the sqlplus client. Next you'll need to setup your TNS name file correctly pointing to your server/database. From then on you should be able to connect using sqlplus from the command line. If that works then you can use the plugins from NagiosExchange I believe you've already encountered . That's the raw procedure, there's lots of information about this on the internet so happy surfing
Correct! You install the client on your monitoring host (nagios server) and don't need to install anything (if only monitoring Oracle databases) on the Oracle server. You're welcome buddy. Good luck and happy surfing!!
You stated you copied the extracted files following the guide. Did you check permissions on those files? There is a sqlplus in the output you posted for the copy command, so most likely the permissions are off.
The tnsnames.ora you can copy from the Oracle server (if you have access), that's the easiest way and the best way to avoid typing errors. Also, executing the sqlplus command of course needs your credentials.
Check if the file sqlplus exists in /usr/bin and check the permissions. If it doesn't then you did something wrong or forgot something.
You can check connectivity to the Oracle database with the tnsping command if I recall correctly, it should be part of the Oracle client package. Of course you'll need the tnsnames.ora file in order to try if I'm not mistaking.
Glad you got that part solved, I was almost sure it were the permissions not set correctly. If you don't have access to the Oracle server to get the tnsnames.ora file, ask the database admin to provide it. The syntax in that file is like such:
The sqlplus command uses the tnsnames.ora file to connect to the database instance in your example using the user scott with password tiger and connecting to database instance myoracle. I never tried connecting directly without tnsnames.ora but found this thread on the internet talking about the same thing. Maybe you can find out how there.
