When running replication task on a DB2/ZOS source endpoint database Replicate uses IFI api to extract CDC data. When the DB2 ZOS endpoint database contains compressed tablesand IFI is reading changes, there could be locking situations (this is a DB2/IFI behaviour).
As a result of this behaviour, when tryning to create TS on this database, you may encounter DSNT376I timeout / deadlock error.
To solve this problem you should perform the following: PAUSE CDC for the time of facility of Replicate on the Mainframe (XMPAUSE/XMRESUME) :
Pause the replicate CDC using the PAUSE CDC facility of Replicate (XMPAUSE/XMRESUME) on the MF endpoint side.
Perform the CREATE TS (as you need)
Resume the CDC.
Pause CDC from the Mainframe will cause the CDC to stop reading changes temporarily and the Tasks on the Replicate side will be waiting till the CDC REUSME.
