REXX Access to VSAM Files Accessing VSAM Files Using Alternate Keys The following example code fragments are written in REXX: v To access the VSAM information using alternate keys, perform the VSAM I/O requests using the PATH cluster. For example: – VSAMC320.BASE is the base cluster. – VSAMC320.AIX is the Alternate Index cluster. – VSAMC320.PATH is the PATH. v To access the VSAM information using the primary keys, ALLOC the BASE cluster, then attempt VSAM I/O requests using DSIVSMX. ’ALLOC FILE(BASE) DSN(VSAMC320.BASE)’ ’DSIVSMX vsmx_func BASE ’ v To access the VSAM information using the alternate keys, ALLOC the PATH, then attempt VSAM I/O requests using DSIVSMX. ’ALLOC FILE(PATH) DSN(VSAMC320.PATH)’ ’DSIVSMX vsmx_func PATH Where vsmx_func is one of the following DSIVSMX functions: OPEN or CLOSE GET or GETREV PUT DEL INQUIRE Deleting an Alternate Index File To delete the base and Alternate Index clusters, delete the base using DSIVSMX IDCAMS with the DELETE CLUSTER parameters. If you delete the base, the alternate index and the path will also be deleted. Using the AUTOTOKE Value Provided by DSIVSMX An AUTOTOKE value is set by DSIVSMX whenever the VSAM file is opened or closed. This value is provided in all messages issued by DSIVSMX, and can be retrieved using the AUTOTOKE() REXX function, or in the output of the DSIVSMX INQUIRE command. To determine that the VSAM file has not been opened or closed since the last I/O, do the following: 1. Save the AUTOTOKE value when the data set is opened. The DSI633I message has the AUTOTOKE() value. Alternately, use DSIVSMX INQUIRE after the DSIVSMX OPEN to retrieve and save the value from the INQUIRE message text. 2. Check the AUTOTOKE value after you issue the DSIVSMX commands. If the value is the same as the saved value, the data set was neither opened nor closed since the last access. DSIVSAM: Access to Keyed VSAM Files Defined by NetView DSTs 342 Programming: Pipes The DSIVSAM command processor can access VSAM keyed files that are defined by NetView data services tasks such as DSILOG. This allows for implementation of all kinds of VSAM applications, including end-use application development in REXX (in conjunction with the pipeline facility) and intensive VSAM diagnostics. For more information about DSIVSAM, see the NetView online help. The DSIVSAM command provides REXX access to any keyed VSAM file on any data services task.
REXX Access to VSAM Files Samples CNMS8016 and CNMS8021 illustrate the use of the DSIVSAM command. See IBM Tivoli NetView for z/OS Command Reference Volume 2 (O-Z) or the NetView online help for more information about the DSIVSAM command. Using the AUTOTOKE Value Provided by DSIVSAM An AUTOTOKE value is set by the data services task (DST) whenever the VSAM file is opened or closed. This value is provided in all messages issued by DSIVSAM, and can be retrieved using the AUTOTOKE() REXX function, or in the output of the DSIVSAM INQUIRE command. If you need to determine that the VSAM file has not been closed or opened since you last did I/O to it, do the following: 1. Use DSIVSAM INQUIRE to retrieve and save the value from the INQUIRE message text. 2. Check the AUTOTOKE value after issuing DSIVSAM commands. If the value is the same as the saved value, the data set was neither closed nor opened since the last access. Chapter 7. REXX Access to VSAM Files 343
