7.9. Adjusting the maximum number of database locks in the IdM Directory Server

Procedure

1. Retrieve the current value of the nsslapd-db-locks parameter and make a note of it before making any adjustments, in case it needs to be restored.

   [root@server ~]# ldapsearch -D "cn=Directory Manager" -w <directory_manager_password> -b "cn=bdb,cn=config,cn=ldbm database,cn=plugins,cn=config" | grep nsslapd-db-locks
   nsslapd-db-locks: 50000

2. Modify the value of the locks attribute. This example doubles the value to 100000 locks.

   [root@server ~]# dsconf -D "cn=Directory Manager" ldap://<server_fqdn> backend config set --locks=100000

3. Authenticate as the Directory Manager to make the configuration change.

   Enter password for cn=Directory Manager on ldap://server.example.com:
   Successfully updated database configuration

4. Restart the Directory Server.

   [root@server ~]# systemctl restart dirsrv.target
