The API (TX_ functions) complying with X/Open can be used with UAPs of OpenTP1. UAPs which perform transaction control with TX_ functions can use other vendors' RM having the specifications conforming to X/Open.
Table 5-6 lists the TX_ functions that can be used with UAPs of OpenTP1. Table 5-7 shows the relationship between OpenTP1 UAPs and TX_ functions.
Table 5-6 TX_ functions available with OpenTP1 UAPs
| TX_ function name | Facility | |
|---|---|---|
| C language | COBOL language | |
| tx_begin | TXBEGIN | Begin a global transaction |
| tx_close | TXCLOSE | Close a set of resource managers |
| tx_commit | TXCOMMIT | Commit a global transaction Chained mode (TX_CHAINED specified) Unchained mode (TX_UNCHAINED specified) |
| tx_info | TXINFORM | Return global transaction information |
| tx_open | TXOPEN | Open a set of resource managers |
| tx_rollback | TXROLLBACK | Roll back a global transaction Chained mode (TX_CHAINED specified) Unchained mode (TX_UNCHAINED specified) |
| tx_set_commit_return | TXSETCOMMITRET | Set commit_return characteristics |
| tx_set_transaction_control | TXSETTRANCTL | Set transaction_control characteristics |
| tx_set_transaction_timeout | TXSETTIMEOUT | Set transaction_timeout characteristics |
