SQL6048N when creating a new instance

Question & Answer


Question

You receive the following error message when using the db2icrt command to create a new instance: SQL6048N A communication error occurred during START or STOP DATABASE MANAGER processing. Update DBM cfg SYSADM_GROUP errcode = 8. DBI1281E The database manager configuration file could not be initialized

Cause

Check that your system's /etc/hosts file is properly configured. DB2® Universal Database™ (DB2 UDB) requires the system's hostname information in order to update the database manager configuration. If the /etc/hosts file is not properly configured, the db2icrt command will fail when you attempt to create a new instance.

Answer

To test if your system's /etc/hosts file is properly configured, issue following command:

ping <hostname>

If it fails, correct the /etc/hosts file so that the proper internet address and corresponding hostname are included. For example:


#Internet Address Hostname
127.0.0.1 localhost
