How to invoke a script upon failover

Hi Mates!

 

In a traditional distributed cluster environment I need to perform a specific action when a node goes from standby to active.

 

I've searched documentation, secureknownledge and community resources but found no out-of-the-box way to accomplish this. The alerts scripts possibility (sk25941) are ran on the management side, so it doesn't suit.

 

Given this I developed a small script that periodically looks into messages file searching for the most recent string "Local machine state changed to ACTIVE" and if that happens in the last 5 second then it performs the desired action.

 

It works fine and I was able to solve the problem, but not sure if this is the most clear way. Does anyone knows if there are any other means for this?

 

Best regards,
