Input values for connection routines
A connection routine can have different input values.
The input values for a connection routine include the following:
The initial primary authorization ID for a local request can be obtained from the z/OS® address space extension block (ASXB).
The ASXB contains at most only a seven-character value. That is always sufficient for a TSO user ID or a user ID from an z/OS JOB statement, and the ASXB is always used for those cases.
For CICS®, IMS, or other started tasks, z/OS can also pass an eight-character ID. If an eight-character ID is available, and if its first seven characters agree with the ASXB value, then Db2 uses the eight-character ID. Otherwise it uses the ASXB value.
If RACF® is active, the field used contains a verified RACF user ID; otherwise, it contains blanks.
- The primary ID for a remote request is the ID passed in the conversation attach request header (SNA FMH5) or in the DRDA SECCHK command.
- The SQL ID contains blanks.
- The list of secondary IDs contains blanks.
