 Posted: Thu Aug 03, 2006 7:51 pm Post subject: CICS reading VSAM Alternate Indexes |
 |
|
I have s vsam ksds which has multiple alternate indexes.
I want to read the ksds using one of the alternate indexes. The only way I can think of to access the alternate index is to read the alternate index directly becasue I don't see anything in the RDO for file definitions that tell cics that a file has vsam aix's or thata file is an aix to a vsam cluster. Any clues or hints?

gkb1278,
A CICS application program does not differentiate whether the file it is accessing is a path or the base. In a running CICS system, access to a single base data set can be made by way of the base and by any of the paths defined to it, if each access route is defined in the file control table (FCT). It is also possible for a CICS application program to access a file that has been directly defined as an alternate index rather than a path.
Hope this helps...
Cheers
