EDM DBD CACHE field (EDMDBDC subsystem parameter)
The EDMDBDC subsystem parameter determines the maximum amount of EDM storage, in kilobytes, that is to be used for DBDs. This storage pool is located above the 2 GB bar.
| Acceptable values: | 5000–4194304 |
|---|---|
| Default: |  40960 1 |
| Update: | press ENTER on panel DSNTIPB |
| DSNZPxxx: | DSN6SPRM EDMDBDC |
Notes:
- Db2 calculates the value when you run the installation CLIST with INSTALL for INSTALL TYPE on panel DSNTIPA1, based on values that you specify on panel DSNTIPD.
When you run the installation CLIST with MIGRATE for INSTALL TYPE on panel DSNTIPA1, Db2 13 uses the Db2 12 field value. For more information, see Calculating storage requirements with the installation CLIST
The Override column of panel DSNTIPC controls whether Db2 uses the calculated value:
- To accept the calculated value, ensure that the Override column contains no value.
- To override the calculated value, specify a value in the Override column.
You can use the SET SYSPARM command to change this value. If the amount of storage that is used exceeds the value of EDMDBDC, the Db2 database manager reduces the amount of storage to the value of EDMDBDC.
