Alternate Index and ESDS.

Post by Anup Apte »

Hi

Mostly I've worked with KSDS and AIX, however, I came to kwno that we can create AIX on ESDS also. I'm confused ESDS does not have any INDEX then how it supports AIX?

Thanks

Physically, an alternate index is a complete different pair of files than the base cluster. There is no requirement to have an index before you can have an alternate index. I've never used an ESDS with an alternate index, so I'm not sure of the advantages.

Possibly to provide the ability to directly access info rather than having to find it serially.

For example - read all info for a particular account or department or whatever.
Hope this helps,

Have done the editing, took a bit but I think it looks neat now.
