XTRANSACTIONS Keyword—ACID Transaction Restriction

Valid on z/OS and z/VSE.

Use the XTRANSACTIONS keyword to restrict ACIDs from using a specific transaction, or subset of the transactions, available within that facility.

This keyword has the following format:

TSS ADDTO(acid) XTRANSACTIONS(facility,(transactions[(G)]))

For purposes of LCF protection, facility entities USER77 through USER221 are not considered unique.

Prefix length: One to eight characters. Entries are treated as a prefix only if the generic indicator (G) follows the entry.
Capacity of list: One to 30 transaction names or prefixes per TSS command.

This keyword is used with:

The commands CREATE REPLACE, ADDTO, and REMOVE
The ACID types User, Profile, DCA, VCA, ZCA, LSCA, SCA, MSCA, and ALL Record
MISC1(LCF) authority to ADDTO or REMOVE the XTRANSACTIONS keyword from ACIDs
MISC9(GLOBAL) authority to ADDTO or REMOVE the XTRANSACTIONS resource class to or from the ALL record.

This example prohibits a group of CICS clerks from using a set of transactions:

TSS ADDTO(PROF1) XTRANSACTIONS(CICSP,(CPO1,CPO2,CPO3))

The letter G next to the transaction prefix indicates that the user is prohibited from using transactions that begin with the prefix specified.

This example indicates that user EJ001 is prohibited from using transactions prefixed by CPO.

TSS ADDTO(EJ001) XTRANSACTIONS(CICSP,(CPO(G)))

This example removes the XTRANSACTIONS restriction:

TSS REMOVE(EJ001) XTRANSACTIONS(CICSP,(CPO(G)))
