Support for the IMS Universal drivers

IMS Connect supports two phase-commit and one-phase commit for IMS DB database requests that are received from IMS Universal drivers.

Global (XA) transactions with the IMS Universal drivers
IMS support for global, two-phase commit transactions for the IMS Universal drivers uses z/OS® Resource Recovery Services (RRS) multisystem cascaded transactions to coordinate database access requests between IMS Connect, the CSL Open Database Manager (ODBM), and IMS within an IMSplex.
One-phase commit global transactions with the IMS Universal drivers
If the external transaction manager detects that only one resource manager is enlisted in a given transaction, the transaction manager can perform one-phase-commit optimization.
