Resolving In Place Alters - Part 4, The Slot Table

By the end of Resolving In Place Alters, Part 3 I was able to read the raw data pages that belong to the table with pending IPAs, but I wasn't able to see if a data page had a pending IPA or not. In this installment I will show you how I solved that problem using what I know about the Informix Data Page structure and the structure of my table before and after the in place alter was performed.

Resolving In Place Alters - Part 3

In Resolving In Place Alters - Part 2 I decided that I want to try to identify only the pages with a pending IPA and only "fix" those data pages in an attempt to speed up the resolving of IPAs and limit the work load added to the system when doing so.

Resolving In Place Alters - Part 2

In Part 1 I talked about how I knew that the prescribed method of resolving the pending in place alters in my large table by simply issuing a single large dummy update statement to update each row won't work for large tables. There are just too many problems with long transactions, locks and excessive I/O that can trash the engine.
