All tableBASE libraries in CICS must be defined as NON RECOVERABLE. This is accomplished with LOG=NO on the FCT or RECOVERY(NONE) on the CSD for any tableBASE library (these settings are defaults in CICS).
The tableBASE software has been designed to ensure the integrity of the libraries, therefore there is no need to use CICS back out and recovery mechanisms.
If CICS is permitted to perform back out and recovery on tableBASE libraries, a transaction interlock occurs. In addition, tableBASE libraries may be damaged during the CICS recovery process.
