BEA-000386 LDAP file (maybe) corrupted

We had some OutOfMemory errors in our server, and finally - after fixing the memory problems - we were unable to start the Admin because of this problem:

moving the AdminServer/data/LDAP directory to a LDAP_BACKUP and restarting the server solved the problem. Of course we lost all the users.

I assume that the LDIF files simply get occasionally corrupted upon OOM. This is quite annoying.

Further digging showed that the file $DOMAIN_HOME/servers/AdminServer/data/ldap/conf/replicas.prop was empty, while it should contain something like this:


#Generated property file
#Mon Nov 21 13:38:21 CET 2011
replica.num=1
replica.0.name=osbdv1ms1
replica.0.base=dc\=osbdv1do
replica.0.port=8001
replica.0.hostname=soa102.acme.com
replica.0.masterurl=ldap\://soa102.acme.com\:7001/
replica.0.masterid=osbdv1as
replica.0.secure=0
replica.0.binddn=cn\=Admin
replica.0.consumerid=osbdv1ms1


How the file managed to get nuked, it's anybody's guess.

The message is: keep a backup of the AdminServer/data directory...
