Another post from the "IDMS Help Desk" series. This was originally posted as "Question for DBAs" - I have expanded the title to make it clear just what the question was! As with previous posts on this blog - the question and replies are in the attachment. Here's Hoping Somebody Will Enjoy This - cheers - GaryC

Subject:     Changing the Number of Files for an Area

 

We have a very large area, that is split between two files.

 

We want to split this area into 10 files, merely by DFSORTING by page number and then stuffing the pages into the appropriate file. The segment/dmcl definition will be changed accordingly.  No unload/reload is planned, due to the time constraints. So far, so good? 

 

Now we also want to do an expand page, after the area has been split into 10 files.

   

This all sounds fine to me, but I am thinking about the SMI, which will be changed to the appropriate size for the expand page, but is the space management interval computed differently depending on the number of files in an area?  Or is space management interval planning done strictly on the page range and page size?

 

Any suggestions would be welcome.

 

Thank you
