bosinst.data large_dumplv stanza
The optional large_dumplv stanza specifies characteristics used if a dedicated dump device is to be created on the systems.
A dedicated dump device is only created for systems with 4 GB or more of memory. The following characteristics are available for a dedicated large dump device:
| Item | Description |
|---|---|
| DUMPDEVICE | Specifies the name of the dedicated dump device. |
| SIZEGB | Specifies the size of the dedicated dump device in gigabytes. |
If the stanza is not present, the dedicated dump device is created when required. A dedicated dump device is created in machines with at least 4 Gigabytes of real memory during an overwrite install. By default, the name of the dedicated dump device is lg_dumplv and its size is determined by the following formula:
4>= RAM < 12 size of dump device= 1 GB
12>= RAM < 24 size of dump device= 2 GB
24>= RAM < 48 size of dump device= 3 GB
RAM >= 48 size of dump device= 4 GB
