Hello All,

I am new to IDMS (its just been 4 months that i am working on idms).
One of my colleague did an ALTER EXPAND PAGE of an area. We did not do UNLOAD-RELOAD of that area yet.
The page size earlier was 5724 and now its 7476.
Because of page size expand and max no of rows allowed per page, there is an increase in amount of unusable space and available space is reduced to 9% from 23% in span of 4 months.

We are now considering to do 1. ALTER the page size back to 5724 and increase page range and 2.UNLOAD-RELOAD of area .

My question is, while doing ALTER of AREA now, do we need to give ORIGINAL PAGE SIZE 7476 (or it should be 5724) and PAGE SIZE 5724 CHAR (as new page size) ? Or no need to mention page size of 7476 at all?

I am confused about the ALTER sytnax to be used.

I think , you may do it in this way,
Code:
ALTER AREA xxxxxx
     PAGE SIZE <new page size>
     ORIGINAL PAGE SIZE <old page size>
     WITHIN FILE zzzzzzz
     FROM   <START-BLOCK> FOR ALL;
