Configuring ClearCase on a mobile computer that is disconnected from and then reconnected to the network

Question & Answer


Question

How can you properly configure IBM Rational ClearCase on a laptop running Windows that is routinely disconnected from the network?

Answer

When using ClearCase on a laptop that is routinely disconnected from the network, the optimal configuration parameters are as follows:



Configure the ClearCase services for Manual start-up

Disable ClearCase network operations

Enable a Hardware Profile and Disable ClearCase Services


Configure the ClearCase services for Manual start-up

REASONS:

  • During logon, the clearcase_albd account attempts to contact the domain for which it is a member for authentication. Since the computer is not connected to the network, login can be delayed unnecessarily.
  • Errors will appear in the logs that the "albd_server must run in the clearcase group". This is due to the fact that domain group membership cannot be checked.

INSTRUCTIONS:
  1. Open the Computer Management Console (Right-click My Computer and select Manage)



  2. Expand Services and Applications and select Services



  3. Double-click Atria Location Broker
  4. Change the Startup type to Manual
  5. Click OK
  6. Repeat steps for Rational (Atria) Cred Manager & Rational (Atria) Lock Manager


Note: When connected to the network, you will need to start the services manually.

Disable ClearCase network operations

REASON:

  • Disabling ClearCase network operations informs ClearCase that the tool is not connected to the network. When the checkbox is cleared, integrations that require access to the ClearCase network are disabled. Review technote 1118151 for more details on Working disconnected from the network in snapshot views.


INSTRUCTIONS:
  • Open to the ClearCase Control Panel (Start > (Settings) > Control Panel)
  • Double click the ClearCase icon
  • Click Options tab
  • Clear the checkbox Connected to the ClearCase Network
  • Click OK

Note: When connected to the network, this checkbox needs to be enabled.
