MAXIMUM SIZE LIMITATION OF A DB2 DMS TEMPORARY TABLESPACE | |
| product: | |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 | |
| Problem description: | |
Database manager erroneously reports that a temporary DMS
tablespace has reached its maximum size, when the reported size
is in fact a value that is below the documented limit.
For example, for a 32K temporary DMS tablespace, you may
observe the following error message in db2diag.log:
2010-02-02-07.51.36.600495-360 E62453858A639 LEVEL: Warning

MESSAGE : ADM6099W Table space "TEMP32K" (ID "2") has reached
the maxiumum size ("549755813888" bytes) for a tablespace of
this type and page size. To add more storage to the database,
add a new table space.
Here, the database manager reports the maximum limit of 512 GB
was reached. However, DB2 info center states that temporary DMS
tablespace is always LARGE and should have a 64 TB limit for
32K pages.
The problem is that database manager incorrectly treats
temporary DMS tablespaces as REGULAR when they should be
considered LARGE.
The problem applies to tablespace with page sizes other than
32K, as well. | |
| Problem Summary: | |
USERS AFFECTED: =============== Customer using version 9.5 and above on all platforms. PROBLEM DESCRIPTION: ==================== DB2 is treating temporary tablespace as REGULAR tablespace when it attempts to grow a temporary tablespace as part of extent allocation. Temporary tablespaces should truly be considered as LARGE/LONG tablespace. Due to this behavior, DB2 will fail stating the maximum capacity is reached when attempting to grow the temporary tablespace beyond 512 GB. The true limit for a large tablespace is 64 TB. This APAR will make sure that DB2 treats a temporary tablespace as a LARGE/LONG tablespace. | |
