nbdb_ping saying the database NBDB is not available

Problem

EMM Server is down and while executing nbdb_ping command it reporting that the NetBackup database (NBDB) is not available.

UNIX/Linux: /usr/openv/db/bin/nbdb_ping
Windows: install_path\NetBackup\bin\nbdb_ping

Error Message

nbdb_ping
Database [NBDB] is not available.

Cause

The vxdbms.conf file is missing port and data entries.

UNIX/Linux: /usr/openv/db/data/vxdbms.conf
Windows: install_path\NetBackupDB\data\vxdbms.conf

Troubleshooting:

• Checked disk space for the volume containing the install directory. (This was fine.)
• Since the master server is clustered, also checked the shared drive for EMM. (This was also fine.)
• Tried command nbdb_admin -auto_start NONE. (Received the error "can not read data line in vxdbms.conf file".)
• Checked vxdbms.conf file. (Found file is shorter than expected.)
• Compared the configuration with a known good, similar machine. (Found there is no port, data, index, and tlog entry.)

Solution

Option 1: The create_nbdb command with the -config_only option creates the vxdbms.conf file from the information available in the bp.conf file.

UNIX/Linux: /usr/openv/db/bin/create_nbdb -config_only
Windows: install_path\NetBackup\bin\create_nbdb -config_only

Note: Some entries in existing vxdbms.conf file can be updated via nbdb_admin command, for additional information see the NetBackup Commands Guide.

UNIX/Linux: /usr/openv/db/bin/nbdb_admin
Windows: install_path\NetBackup\bin\nbdb_admin

Option 2: Manually edited the vxdbms.conf file and create the missing entries:

VXDBMS_NB_PORT = 13785
VXDBMS_NB_DATA = <PATH_TO_DB_data>
VXDBMS_NB_INDEX = <PATH_TO_DB_data>
VXDBMS_NB_TLOG = <PATH_TO_DB_data>

Note: Suggest referencing a known good server with the same configuration to compare with, otherwise open a case with support for additional guidance.

After the configuration has been updated and NetBackup services are restarted, the nbdb_ping command should now show:

Database [NBDB] is alive and well on server [NB_<masterservername>].
