Restoring WebSphere Application Server Profiles - NullPointerExceptions

So, for some reason, I was having a crisis of confidence  / memory.

I was trying/failing to restore a WebSphere Application Server (WAS) profile, using the following command: -

/opt/ibm/WebSphere/AppServer/bin/manageprofiles.sh -restoreProfile -backupFile /home/wasadmin/wasbackups/BPM86_Dmgr01.zip 

which failed with: -

It took me a while of faffing around ….. including creating new profiles ….

And then I realised where I was going wrong ….

Given that I had backed up the profiles: -

mkdir wasbackups
cd wasbackups/
/opt/ibm/WebSphere/AppServer/profiles/AppSrv01/bin/backupConfig.sh BPM86_AppSrv01.zip
/opt/ibm/WebSphere/AppServer/profiles/Dmgr01/bin/backupConfig.sh BPM86_Dmgr01.zip

perhaps it'd have made more sense to use …. restoreConfig.sh instead.

Guess what …..

/opt/ibm/WebSphere/AppServer/bin/restoreConfig.sh /home/wasadmin/wasbackups/BPM86_Dmgr01.zip
