Look into JMS filestore

For many reasons sometimes is necessary to lookup JMS filestore directly, this can be achieved through:

1.
java weblogic.store.Admin

2.
storeadmin-> openfile -store FileStore-FileStore1 -dir /tmp/filestore-local

3.
storeadmin-> dump -store FileStore-FileStore1 -out /Users/German/tmp/filestore-local-dump.xml -conn -deep
4.
list -dir /tmp/filestore-local

It can be used for compressing the store as well.
