Use the following attributes in the DataConnector operator definition to specify the optional use of an access module:

  • AccessModuleName

    Each access module has a pre-assigned name depending on the operating system on which it is installed. For instance, the JMS access module running on HP-UX Itanium is named libjmsam.so.

  • AccessModuleInitStr

    Specifies the access module initialization string.

For detailed information about configuring and using access modules with Teradata PT, see Teradata Tools and Utilities Access Module Reference (B035-2425).

For information about creating custom access modules, see Teradata Tools and Utilities Access Module Programmer Guide (B035-2435).

z/OS Considerations

When using access modules residing within a z/OS program library, either a PDS or a PDSE, the access module name provided to the producer operator using the AccessModuleName attribute is the member name within the library. It may be a system library, private library, or even a temporary library.

If a system library contains the access module, no further JCL is required. However when a private or temporary library houses the access module, a JOBLIB DD statement or a STEPLIB DD statement is required within the jobstream to designate the library containing the access module. The following example shows a typical JOBLIB DD statement for a private library in a Teradata PT jobstream:

//JOBLIB  DD  DISP=SHR,DSNAME=STV.TI70APP.TWB.LOAD
//        DD  DISP=SHR,DSNAME=STV.TI70APP.APP.L
//        DD  DISP=SHR,DSNAME=PROD.TERADATA.LOAD

where:

  • STV.TI70APP.TWB.LOAD is the Teradata PT installation library.
  • STV.TI70APP.APP.L is the CLI installation library.
  • PROD.TERADATA.LOAD is a private library that contains all Teradata related access modules.

The above is the recommended concatenation order for these libraries.
