IMPTKMOD in macro DSN6SYSP
Specifies the default TRACKMOD option for CREATE TABLESPACE statements and implicitly created tables spaces, which specifies that Db2 tracks changed pages of the base table space in the space map pages.
| Acceptable values: | YES, NO |
|---|---|
| Default: | YES |
| DSNZPxxx: | DSN6SYSP IMPTKMOD |
| Security parameter: | No |
- YES
- Db2 tracks changed pages of the base table space in the space map pages. This tracking is intended to improve the performance of incremental image copies. YES is the default value.
- NO
- Db2 does not track changed pages in the
space map pages. Db2 uses the LRSN value in
each page to determine whether a page has been changed.
If you specify an SAP-specific input member (for example, DSNTIDXB) during installation or migration, the DSNTIJUZ job that is generated by the Db2 CLIST specifies IMPTKMOD=NO.
The setting is not used for LOB or XML table spaces.
