ARTTSQP manages temporary storage queues which are defined in TS pool. It serves the functionalities required by EXEC CICS (WRITEQ TS, READQ TS and DELETEQ TS). Two versions of ARTTSQP server are delivered: ARTTSQP (for Oracle DB) and ARTTSQP_UDB (for UDB). TMS and OPENINFO must be defined accordingly. Every CICS region can have multiple ARTTSQP servers, and different Tuxedo domains can use the same database; therefore, the TS queue can be shared among different CICS regions in Tuxedo domains.

The fact that you can configure more than one ARTTSQP servers to serve for the same TSMODEL features the HA capability of ART for CICS.
