View and VOB creation errors in ClearCase Interop

 Technote (troubleshooting)

Problem(Abstract)

This technote describes why errors may occur during view and VOB creation in an IBM® Rational® ClearCase® Interoperation environment with UNIX® or Linux® with Microsoft® Windows®, and provides a possible reason why these errors occur along with a solution.

Symptom

Attempts to create a VOB from the GUI results in the following error:

VOB Creation

Graphical Interface

Using the VOB Creation Wizard fails with the following error:

Error creating VOB :
VOB Creation Wizard: Error: Problem starting vob_server for vob HOST3:\\HOST3\vobs\test_vob.vbs
VOB Creation Wizard: Error: See albd or VOB error logs on host HOST3
VOB Creation Wizard: Error: Warning: Error initializing vob_server.
VOB Creation Wizard: Error: INTERNAL ERROR detected and logged with the NT Event Service.
See the Event Viewer for the error message.
Internal Error detected in ".\../map.c" line 2106
VOB Creation Wizard/vob/map: Error: Null VOB handle passed to libvob routine.
VOB Creation Wizard: Error: Unable to create versioned object base "\\HOST3\vobs\test_vob.vbs".

OR

The following error occurs:

Error accessing storage path location
Status=8274016

Command Line

Attempts to create a VOB from the CLI results in the following error:

cleartool: Error: Problem starting vob_server for VOB HOST3:\\HOST3\syntax\tas_vob.vbs
cleartool: Error: See albd or VOB error logs on host HOST3
cleartool: Warning: Error initializing vob_server.
cleartool: Error: INTERNAL ERROR detected and logged with the NT Event Service.
See the Event Viewer for the error message.
cleartool: Error: Unable to create versioned object base "\\HOST3\syntax\tas_vob.vbs".

View Creation

Attempts to create a dynamic view from either the Clear View Tool or the command line results in the following error:

Error creating view -- 'test_view'.
clearviewtool: Warning: Config spec OK, but unable to tell view server to load.
clearviewtool: Warning: View server should be restarted.
clearviewtool: Error: Set configuration spec of C:\Program Files\Rational\ClearCase\default_config_spec failed: view storage directory or control files unavailable --
additional information may be present in the view server host's view log
clearviewtool: Error: Unable to create view "\\HOST3\viewstore\test_view.vws"

Cause

These errors occur when creating a VOB or dynamic view from Windows and attempting to store it on a UNIX or Linux host.

Resolving the problem

UNIX and Linux

VOB and view storage created on a UNIX system must be created from the UNIX Operating System.

Windows

VOB and view storage created on a Windows system must be created from the Windows Operating System.

Region Synchronizer

In order to use or see a VOB or view that is stored on UNIX from Windows, the Region Synchronizer in the ClearCase HomeBase can be used.

The Region Synchronizer (RegSync) helps a ClearCase administrator maintain the ClearCase VOB and view registries in network installations where Windows systems require access to UNIX VOBs and views.

RegSync coordinates, or synchronizes, VOB and view names (VOB-tags and view-tags) between UNIX and Windows network regions.

Note: RegSync exists only on Windows.

Importing Tags from UNIX to Windows

The typical usage pattern for RegSync has two phases:

1. The administrator uses RegSync to "import" a set of UNIX VOBs and views, making them accessible to a network.
   
   
2. Thereafter, the administrator uses RegSync intermittently to add Windows region support for one, or several new UNIX VOBs, or views.
   

Overview of Using the Synchronize ClearCase Regions dialog box:

From the Region Synchronizer's main dialog box, use the following general procedure:

1. Specify either VOB-tags or view-tags.
2. Verify that the Windows and UNIX network region names are correct.
3. Select a UNIX VOB or view.
4. Click on Import..., and then complete the resultant "make tag" dialog box to create a tag in the Windows region for the selected VOB or view.
   
   Click the HELP button in the Region Synchronizer for more detailed assistance.
   

Importing VOB Tags from UNIX to Windows

The RegSync utility detailed above is only available for importing tags to Windows from UNIX or Linux.

Note: Views cannot be shared from Windows to UNIX or Linux.
