WebLogic Server Hangs at Startup : Beware if you Disk is 100% full

Tue, 2016-02-02 16:43
This entry is part 5 of 6 in the series WebLogic Server

We were recently implementing  Oracle Fusion MiddleWare for one of our Customer in United Arab Emirates and we encountered issue on WebLogic Server where startup of WebLogic Server hangs (WebLogic is heart of Fusion Middleware that is now used in almost every Fusion Middleware Product and also in E-Business Suite R12.2 and Peoplesoft) which we have described below.

Issue:

While starting WebLogic Admin Server, WebLogic Server was not coming up or hangs at startup at one point without generating any logs. This might come due to many reasons.

WebLogic Server 10.3.6.0 Tue Nov 15 08:52:36 PST 2011 1441050 >
<Jan 29, 2016 3:42:26 AM PDT> <Notice> <WebLogicServer> <BEA-000365> <Server state changed to STARTING>
<Jan 29, 2016 3:42:26 AM PDT> <Info> <WorkManager> <BEA-002900> <Initializing self-tuning thread pool>
<Jan 29, 2016 3:42:26 AM PDT> <Notice> <Log Management> <BEA-170019> <The server log file /mydomain/WLS/user_projects/domains/wls_mydomain/servers/AdminServer/logs/AdminServer.log is opened. All server side log events will be written to this file.>

Cause:

Earlier, we were facing Disk Space Issue (mount where WebLogicDomain directory configured was 100% full) and we got one message as ” No Disk Space Left on Device” because of which WebLogic Admin Server for BI Publisher got into hang state. After providing some Disk space to on the server it was not coming up and stuck at above point.

Fix:

After further investigations, we came to know the issue was with data folder inside /mydomain/WLS/user_projects/domains/wls_mydomain/servers/AdminServer/data folder, so to check if its really issue with data folder we renamed/moved the data folder to data_backup (as this was test environment) and tried to start it again. We analysed the server recreated the data folder by itself (from Admin Server) and started up fine without any hangs.
