rebasing config spec in clear case

问题:

I am new clearcase I am trying to rebase the branch m_tool. Could you please tell me how should i go about rebasing for the following config spec?

element * CHECKEDOUT
element * DATASOURCE
element /entities/... /main/LATEST 
element * .../m_tool/LATEST 

mkbranch m_tool
element * .../branch2011/LATEST 
element * TAG_2010_OCT_02
element * .../m_dd_lt_hfix/LATEST 
element * TAG_2010_02_DEV_BASE
element * /main/LATEST 
end mkbranch m_tool

Thank you, Dennis

"Rebasing" is a merge between a parent UCM stream and a direct child Stream.

What you show is a base ClearCase config spec, not an UCM one.

That config spec would show the latest on m_tool branch, and, for version which haven't yet any m_tool branch:

• the latest of branch2011
• or, if no branch2011, the tag TAG_2010_OCT_02
• or if no tag TAG_2010_OCT_02, the latest of branch m_dd_lt_hfix
• or, if no branch m_dd_lt_hfix, the tag TAG_2010_02_DEV_BASE
• or, as a stop rule, the latest of main branch

In each case, if a version is done, you would create it on the m_tool branch.

If that is what you mean by "rebasing", then it is correct.

I want m_tool to have everything, instead of looking at each tags/branch.

Then you would need to merge a view which display only non m_tool versions:

element * .../branch2011/LATEST 
element * TAG_2010_OCT_02
element * .../m_dd_lt_hfix/LATEST 
element * TAG_2010_02_DEV_BASE
element * /main/LATEST 

And merge that view an m_tool-only view:

element * .../m_tool/LATEST 
element * /main/0 -mkbranch m_tool
element * /main/latest -mkbranch m_tool
