sqlxphcm API - Commit an indoubt transaction

API and data structure syntax

extern int SQL_API_FN sqlxphcm(
   int exe_type,
   SQLXA_XID *pTransId,
   struct sqlca *pSqlca
   );

sqlxphcm API parameters

exe_type: Input. If EXE_THIS_NODE is specified, the operation is executed only at this node.
pTransId: Input. XA identifier of the transaction to be heuristically committed.
pSqlca: Output. A pointer to the sqlca structure.

Usage notes

Only transactions with a status of prepared can be committed. Once heuristically committed, the database manager remembers the state of the transaction until the sqlxhfrg API is called.
