DE Primary Server File

[TRAVIS ANDERSON]

Hi, i was wondering if there is a file that can be searched at any time to find whether or not that particular server is the primary or secondary server. I'm looking for some sort of file located on both primary and secondary servers that can tell me which one is primary

[Roya Phamgia-Piroux]

Hi Travis,

 

You can use the CLI utility as it always runs commands against the active server (unless you specify the standby operand in the command).

 

Please consult the following docops page for more information.

 

Failover Support in the Stand-Alone Command Line Interface - CA Workload Automation DE - 12.0 - CA Technologies Document… 

 

I hope this can help.

 

Thanks,

Roya

Thanks for the info. Due to what I am trying to do, I was trying not to go that route and maybe just parse a file instead.

Hi Travis,

Hope you are doing well. 

When DE switches from primary to standby there are SNMP messages not sure if you could use those. 

I also forced a fail over on our LAB env and I found these messages in the tracelog and stdout.txt log

c80001> grep -a 'Switching Roles' *

grep: buffer: Is a directory

not sure if you can use any of this but I had time and I thought there had to be a way

Thanks for the info Sharon! I love that you are driven to find the answer  The stdout file "may" work for our situation. I will keep this in mind and bring it to another team who is working on some automation things that will be using DE.

 

Have a great weekend!
