WebLogic server hanging on startup

This is so typical...

Delete the $DOMAIN_HOME/servers/myservername/data/ldap folder and the $DOMAIN_HOME/servers/myservername/security/boot.properties file.

cd $DOMAIN_HOME/bin

./startManagedWeblogic.sh myservername

enter weblogic username and password

If some OSB (ALSB) deployments fail, make sure you remove all configuration files with 0 size from the admin host:

cd $DOMAIN_HOME/config

find . -size -1 -exec ls -l {} \;

find . -size -1 -exec rm {} \;
