Hey Gopalakrishna, Make a new instance using koha-create. Look at the /etc/koha/sites/<instance name>/koha-conf.xml file in the new instance. There will be a <lockdir> line in the file. Add that to your old instance koha-conf.xml file, with the appropriate instance name. You may also need to create the directory on the server, and chown and chgrp the directory to be owned and group assigned to your instance user name. Also, check the About Koha page. Do you have a warning that says Zebra is not running? You may just need to start it.
