How to start weblogic server after improper shutdown

Today one of my application server got rebooted automatically due to insufficient memory.When we tried to start weblogic ,we were getting below exception in logs.

"Reason: weblogic.store.PersistentStoreFatalException: [Store:280105]The persistent file store "UMSJMSFileStore_auto_2" cannot open file UMSJMSFILESTORE_AUTO_2000000.DAT.> 
weblogic.management.DeploymentException: java.io.IOException: Error from fcntl() for file locking, Resource temporarily unavailable, errno=11"



We  need to do below steps to start weblogic.


1. From your ...domains/[DOMAIN] directory (and below) find and move all *.DAT files

mkdir /tmp/bkup
export BKUP_DIR=/tmp/bkup
cd $DOMAIN_HOME
find . -name *.DAT
find . -name *.DAT   -exec mv -t $BKUP_DIR  {} \;



2. Find and move all lok files in a similar method

cd $DOMAIN_HOME
find . -name *.lok
find . -name *.lok   -exec mv -t $BKUP_DIR  {} \;


3. In case if you configured JMS,we need to remove *.DAT files from the jms location as well.We have SOA managed server with clustering.our second node got rebooted.so we need to find the files which contains *AUTO_2000000* in name and move


cd /u01/oracle/config/domains/soa_domain
find . -name *AUTO_2000000*
find . -name *AUTO_2000000*  -exec mv -t $BKUP_DIR  {} \;


4.Mostly persistent store location will be inside domain_home.But in our case(SOA) we stored it in the different location.so we had to  move the *.DAT file from default persistent stores  location.

cd /u01/oracle/config/domains/soa_domain
find . -name _WLS*2000000*DAT
find . -name _WLS*2000000*DAT -exec mv -t $BKUP_DIR  {} \;

5.Now try to start Weblogic,Hopefully it will start.
