Purpose

Specifies the maximum amount of memory, in pages, an AMP or PE can use to store global and persistent (GLOP) data mappings. A page of memory is 4096 bytes.

GLOP data is a type of data available to external routines. The persistence in memory of GLOP data is based on specific boundaries, such as a user role or user account.

This value should be changed only under the direction of Teradata Support Center personnel.

Valid Range

0 through 16777216 pages (64 GB)

System memory availability, system disk availability, and system performance considerations can substantially reduce the upper limit.

Default

2560 pages
