Unable to login into WebSphere Application server of RTC

Hello Fazal,

I am assuming you are not able to log into the WebSphere administrative console.  The first thing I would attempt is the following:
1. Stop WebSphere
2. Clear out the following temp directories
<WebSphere_Install_Root>\profiles\(profile_name)\wstemp
<WebSphere_Install_Root>\profiles\(profile_name)\temp
<WebSphere_Install_Root>\profiles\(profile_name)\config\temp
3. Clear out the RTC and WebSphere logs located at
<WebSphere_Install_Root>\profiles\(profile_name)\logs
In this directory there will be two sub directories \ffdc and \(server_name) ... either remove or rename these directories.  During startup WebSphere will recreate.
Also the jts.log, ccm.log ext are located in this directory.  May be a good idea to remove these as well so that we have a clean set of logs when restarting WebSphere
4. Restart WebSphere
5. IF the issue persists, open a PMR against WebSphere and upload the WebSphere logs to the PMR.  This way the WebSPhere admin team can look into this issue.

You can try clearing the temp folder.

1) Stop WAS
2) Remove all files from "/opt/IBM/WebSphere/AppServer/profiles/Dmgr/wstemp/"
3) Restart WAS

Found a WAS technote on this:

Hi Shubjit & Abraham,

    Thanks for your answers. Yes. the issue was due to space issue in RTC. Cleared some space and it's working fine.
