Clients list not displayed under ClearCase Network in the Administration Console

Problem(Abstract)

This technote identifies a defect whereby no clients are listed when clicking ClearCase Network in the IBM® Rational® ClearCase® Administration Console on Microsoft® Windows®.

Symptom

When selecting the ClearCase Network option in the Administration console, no clients are listed although there are entries correctly listed in the client_list.db file. The ClearCase Registry server collects information about client hosts that have recently accessed the registry server. This information is stored in the client_list.db file which is located by default in the /var/adm/rational/clearcase directory on UNIX® or Linux® or in the C:\Program Files\Rational\ClearCase\var directory on Microsoft® Windows®: A restart of ClearCase does not resolve the issue.

Cause

The cause of this problem is that IBM Rational Common Licensing (FLEXlm) is being used and the Administration Console does not have any data to read from the FLEXlm license server to populate the "ClearCase Network." The FLEXlm license server does not keep a list of clients that access it and therefore cannot populate the "ClearCase Network" list. FLEXlm licensing, also known as IBM Rational Common Licensing, is an available licensing scheme for use with Rational ClearCase 7.0 and later versions. The following example shows how the output would typically be displayed. When experiencing the problem described in this technote, the data you see listed under "ClearCase Network" would not be displayed. Other symptoms would include the following: Clicking on the ClearCase Network in the Administration Console will list the registry server name at the top with no license server name only displaying empty quotes. For example: ClearCase Network Hosts using ClearCase as recorded by the registry server 'my_server' and the license server ' ' Clicking on the Hosts icon in the Administration Console under "ClearCase Registry" the "License Server" column does not contain a value for any ClearCase host that uses FLEXlm licensing. This has been reported as defect PK53129.

Resolving the problem

The decision was made by Product Management to exclude the resolution of this defect from future upgrades and releases. WORKAROUND: To display a list of all the clients that contacted the registry and or license server, the following command can be run from a command prompt: cleartool lsclients -host -type registry Review the IBM Rational ClearCase Command Reference on the topic of lsclients (cleartool man lsclients) for more information.
