"Unable to contact albd_server on host" when starting or creating a view

Technote (troubleshooting)


Problem(Abstract)

Attempts to start or create an IBM Rational ClearCase view causes "cleartool: Error: Unable to contact albd_server on host 'remote server'" error.

Symptom

The following errors occur when you attempt to either start a view or create a view.

Windows Example:

# cleartool startview my_view
cleartool: Error: Unable to contact albd_server on host 'remote server'
cleartool: Error: Couldn't set view tag my_view: ClearCase object not found


The server to which the view is stored does not have the ClearCase ALBD service running.

UNIX / Linux Example:


# cleartool mkview -tag mtest /net/server/views/my_view.vws
cleartool: Error: Unable to contact albd_server on host 'remote server'
cleartool: Error: Cannot bind an admin_server handle on "remote server": ClearCase object not found.
cleartool: Error: Unable to create view "/net/server/views/my_view.vws".


Cause

Possible causes for the error:

  1. The view is being stored in a mounted directory, but the system that the mounted directory is stored on does not have ClearCase running or installed. If ClearCase is installed, there might be an issue with MVFS on that host.

  2. (Windows) This error can also result if the network password for the "Atria Location Broker" service account (by default: clearcase_albd) has been changed.

Resolving the problem

Solution 1

Check your configuration performing following steps:

  1. Investigate the host where the view storage resides ensuring that ClearCase is running and for dynamic views, that there are no problems with the MVFS.

  2. Check if ClearCase is installed and started on each server host that is in use in a ClearCase environment, unless you are using alternate protocols like ClearCase Remote Client (CCRC) or ClearCase Web (CCWeb).

  3. Refer to Rational ClearCase server processes for further information about the processes that are run on view and VOB server hosts.

  4. Ensure that ClearCase is installed on the view server host and it is started; otherwise, create or move the view to a system that has ClearCase installed and running. Review the Starting and stopping Rational ClearCase section of IBM Rational ClearCase Administrators Guide under the topic of Rational ClearCase network planning and administration for information about starting and stopping ClearCase.

Solution 2

(Windows) If the ClearCase service account network password has been changed, it also needs to be updated on the local machine. Refer to 1146207: Methods for changing the ALBD password for albd_server.exe for further details about the clearcase_albd service account.
