Describes Micro Focus-specific xa_open string options available for defining XARs.
Enterprise Server provides xa_open string options for XARs in addition to those provided by each database vendor.
You can add these options to a resource definition by including them in the xa_open string using the format specified by the
database vendor. For example, most databases use a comma separator (,), but Oracle uses a plus sign (+) separator. See your
database documentation for more information.
- LocalTX={T|F}
- Determines how the XAR handles transactions.
- T
- The associated XAR uses local (non-distributed) transactions. This option reduces overhead, and therefore can be a good option
when using a single XAR. Be advised, however, that
LocalTX=T also handles commits and roll backs for each XAR, independent of other resources, and should be used with care.
- F
- The associated XAR uses XA distributed, global transactions. Default.
- ISOLEVEL={CR|RO|RR|SS|SZ|UR}
- Determines the isolation level of transactions for a specific XAR.
