About the vxdbd daemon
Prev	Introducing Veritas Storage Foundation for DB2	Next

The vxdbd daemon handles communication to and from the Veritas Storage Foundation for DB2 software. By default, vxdbd communicates with Veritas Storage Foundation for DB2 over port number 3233. If there are conflicts with this port or other port-related problems, you can change the port by changing the VXDBD_SOCKET setting located in the /etc/vx/vxdbed/admin.properties file.

Normally the vxdbd daemon starts automatically when the host boots up. However, if the daemon reports errors or if the daemon process dies, you may have to manually start or stop it. There is also a status command that reports the current state of the daemon to confirm that it is currently running.

Only the root user can stop vxdbd. Any user can start vxdbd or display its status.

Note:

You must have a valid HOME directory for vxdbd to work correctly with several Veritas Storage Foundation for DB2 features. If you receive the following error message, but you confirm that vxdbd is running (using ps -ef | grep vxdbd rather than vxdbdctrl status), you may not have a valid HOME directory or it may not be available to vxdbd:

VXDBA_PRODUCT exec_remote ERROR V-81-7700 Can not connect to the vxdbd.

To see the status of the vxdbd daemon

Use the vxdbdctrl status command:
```
/opt/VRTSdbcom/bin/vxdbdctrl status
```
If the daemon is running you see the following output:
```
vxdbd is alive
```

To start the vxdbd daemon

Use the vxdbdctrl start command:
```
/opt/VRTSdbcom/bin/vxdbdctrl start
```

To stop the vxdbd daemon

As root, use the vxdbdctrl stop command:
```
/opt/VRTSdbcom/bin/vxdbdctrl stop
```

To change the communications port used by the vxdbd daemon

As the root user, stop the vxdbd daemon:
```
/opt/VRTSdbcom/bin/vxdbdctrl stop
```
In the /etc/vx/vxdbed/admin.properties file, change the value of the VXDBD_SOCKET variable to a new port number:
```
VXDBD_SOCKET=3233
```
Restart the vxdbd daemon:
```
/opt/VRTSdbcom/bin/vxdbdctrl start
```
If the system is part of a multi-host configuration, change the port on all hosts involved by repeating this procedure on each host.
Restart the DBED agent vxpal.

See the section "Starting the DBED agent" in the Veritas Storage Foundation for DB2 Graphical User Interface Guide.
