[389-users] How to increase the number of DB locks on the 389 Directory

[Glenn Machin]

Looking at the source code - I fixed the problem by doing the 
following.   If there is an easier way let me know.

Shutdown down the 389 directory

Edited /etc/dirsrv/slapd-SERVER/dse.ldif

Under dn: cn=config,cn=ldbm database,cn=plugins,cn=config
added attribute:
nsslapd-db-locks: 40000


Dumped the userRoot DB
/usr/lib64/dirsrv/slapd-SERVER/db2ldif -n userRoot

(Note this starts slapd so you have to stop the server again)

Reload userRoot
/usr/lib64/dirsrv/slapd-SERVER/ldif2db -n userRoot -i 
/var/lib/dirsrv/slapd-SERVER/ldif/SERVER-userRoot-DATE.ldif

Start the server

Looked at the configuration attributes:
ldapsearch -h localhost -p 389 -D "cn=directory manager" -W -x -b 
"cn=database,cn=monitor,cn=ldbm database, cn=plugins,cn=config" 
objectclass=* | grep lock


nsslapd-db-configured-locks is now set to 40000
