UPDATE STATISTICS HIGH FOR A TABLE USING FRAGMENT LEVEL STATISTICS MAY CONSUME EXCESSIVE MEMORY | |
product: | |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 | |
Problem description: | |
When running update statistics high for a table using fragment level statistics and containing many fragments the amount of memory used by the session may become very large. For example a table defined with interval fragmentation having 620 million rows over more than 600 fragments consumed around 2.4 GB memory for a sort pool when running update statistics high for a serial8 column. If the table schema is altered so that fewer fragments are used then the update statistics command will require less memory. | |
