Dear All,
When I tried to load share memory,
error as below,
Unknown program domain tttxt.kwrd used in object ottdsk1300m000.

How to check it?

The domain should be existing in the Tools domain's definition file:

${BSE}/tools/dd/dtt.pd/dtt.pd

Sometimes, between the tools patches & service/feature-packs some objects can be expired, so its a good idea to regenerate the shared memory file from session ttaad4150m000.
