Status: Closed |
EXCESSIVE MEMORY USAGE DURING ARCHIVE WHEN CHUNK CONTAINS 2,147,483,647 PAGES
|
| product: |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 |
| Problem description: |
The maximum number of pages in a chunk is 2,147,483,647
(0x7fffffff).
Archiving a dbspace with a chunk of this size can use an
excessive amount of memory when starting the archive and there
is a reasonable chance it will fail with an error comparable to:
CDR 4026531841 byte memory allocation failed (Pool:arc_4667763
Thread:ontape).
Assert Warning: ISAM error: An error has occurred during
archive back up.
