EBS 12.2 - apps.conf

[Aj]

Hi, I wanted to ask whats the role of apps.conf in EBS 12.2? We have a 4 MT node cluster and the order of the nodes listed in this configuration file is having an impact on launching the forms. So what happens is - if the order of the nodes listed in this file is Node1, 2, 3, 4 and node 1 is down, the forms dont launch and the browser keeps spinning. Now if I change the order and make it like Node2,3,4,1 and then Node 1 is down. The forms launch OK. Is that a normal behavior? Any pointers detailing the role and function of this file will be helpful. Thanks!

1)Is forms server 2 running?
2)Any errors in form server 2's error log?(managed server log)
3)What do you see when you enable java console trace?
4)Did you enable browser trace and reproduce the issue? (what does browser try to do? what is the redirection(url) there? What url does browser try to redirect?)

1)Is forms server 2 running? - Yes, all other servers and services on 2,3 and 4 are running.
2)Any errors in form server 2's error log?(managed server log) - No, no error message.
3)What do you see when you enable java console trace? - It tries to load various jar files.. stops for 5-10 minutes on loading each jar file.
4)Did you enable browser trace and reproduce the issue? (what does browser try to do? what is the redirection(url) there? What url does browser try to redirect?) - None, it just stays there.

Can you point me to any documentation on the apps.conf file?

Thanks!

there is no specific documentation for apps.conf.
It is one of the HTTP Server configuration files in EBS 12.2
apps.conf should contain entries of managed servers from all Application tier nodes.
It is maintained by running the perl script txkSetAppsConf.pl.

Do your entries in mod_wls and apps.conf seem okay? If so, why not you check the things that I pointed out.

*Browser trace is important. We need to see what browser tries to do, and what it tries to redirect.
*Java console output is also important (but you need to enable trace in java, before reproducing the issue and checking java console..) -- waiting for those jar files for 5-10 minutes, may be the case.. Is your network okay? No blocking right?
*Retry after regenarating the jar files.. (this is a test env right?, if it is PROD, the risk is yours)
*Did you ever use this second node earlier? Did your forms session ever created in the forms server of this second node? Maybe it is misconfigured?
