Automatic sizing of output copies dynamically allocated on DASD
You can use
BMC AMI Recover
to automatically size DASD output copies dynamically when the primary allocation quantity is not specified by the SPACE option.
Automatic sizing occurs if all of the following conditions exists:
- You are using OUTCOPY (OUTCOPY-specification).
- The copy is dynamically allocated (using the OUTPUT command).
- You did not specify the primary quantity with the SPACE option (SPACE (primary, secondary) allocation unit).
- You specify either the AUTOSIZE=YES installation option (AUTOSIZE-YES) or YES for the AUTOSIZE option on the OPTIONS command (AUTOSIZE).
Optionally, you can use the MAXPRIM option on the OUTPUT command to set a maximum amount of disk space (in the units specified by SPACE) to allocate as primary space. Valid values are 0 through 65535. A nonzero value for MAXPRIM establishes an upper limit for primary space allocation, while a value of zero specifies no limit.
BMC AMI Recover calculates a value for the primary allocation and uses it if it is less than MAXPRIM. Then BMC AMI Recover calculates the secondary allocation as 20 percent of the primary allocation.
If the calculated value for the primary allocation exceeds MAXPRIM, BMC AMI Recover uses the MAXPRIM value. The secondary allocation is based on the remainder of (calculated primary allocation - MAXPRIM).
When automatic sizing occurs for OUTCOPY, the following message is in the MERGE phase output indicating the allocation values that BMC AMI Recover calculated:
