Rational clear case CM API fail to checkout source

问题:

I am trying to connect clear case server using Java code with help IBM ClearCase CM API.
Currently I have below setup:

1. I have clear case client (CCRC) 7.1 is install on my machine.
2. View is created with model type VOB using CCRC client.

If I try to checkout code using above Java code it showing below error:

CRVAP0087E (conflict): CCRC command 'checkout' failed: Unable to find VOB object
for "E:\ccweb_views\akash.sharma\akash.sharma_AR_TAS_Release1_dev\": 
not a ClearCase object 
Version discordance detected for "E:\ccweb_views\akash.sharma\akash.sharma_AR_TAS_Release1_dev\".

You could first try to resolve the "discordance" issue: See technote swg21223087.

The server and client are in disagreement about the state of the element version in question. This is known as discordance.

This state can occur after you undo checkout or undo hijack on a file or directory element.

Discordance will also occur in the following scenario:

1. CCRC client loads a file (foo.txt)
2. Native ClearCase client renames file (foo.txt to FOO.TXT changing the case ONLY) in dynamic view
3. CCRC client performs "update resources" operation
4. CCRC will see FOO.TXT in a discordance state

Solution (help page):

1. Select the resources that you want to restore. You can select individual resources or an entire ClearCase view. (Restoring a resource that is not in an unknown state has no effect on the resource.)
2. To open the Restore Resources dialog box, take either of the following actions:
   • Select Refresh > Repair Discordance from the ClearCase menu.
   • Select Refresh > Repair Discordance from the element context menu or Refresh > Repair > Discordance from the view context menu.
3. Specify restore options in the dialog box and then click Apply.
