Once so often, I run into the following error command upon ICFB
startup:
*WARNING* file /home/students/pc357/CDS.log File is already locked by
some other process.

Subsequently, I can only open schematics/layout files in the "Read-
Only" mode. All write permission are denied.

There is a webpage which documents this file-locking problem:
http://www-bsac.eecs.berkeley.edu/~cadence/tools/file_lock.html

In short, type "clsAdminTool" at the terminal command. Type "ale ." to
find out what the locks are. and Type "asre <filename>" to release the
relevant lock. The following is an example log:

clsAdminTool

Hope this helps, in case anyone else runs into the same problem.
