OUTSIZE

OUTSIZE specifies a size threshold for making copies to an alternate DD or output descriptor. For example, you can use OUTSIZE to escalate output to Instant Snapshots rather than standard copies.

You can specify OUTSIZE as the number of 4-KB physical pages. Valid values for number of pages are 0 through 1,073,741,823. This can be specified as OUTSIZE integer or as OUTSIZE integer P.

You can also specify OUTSIZE in kilobytes, megabytes, or gigabytes as follows:

  • OUTSIZE integerK, with a limit of 4,294,967,295
  • OUTSIZE integerM, with a limit of 4,194,303

  • OUTSIZE integerG, with a limit of 4095

    If you specify a value greater than 0 and the space or partition being copied is less than the value specified with OUTSIZE, the image copy goes to the DDs as normal (using COPYDDN, RECOVERYDDN, COPYDSN, RECOVERYDSN, FULLDDN, FULLRECDDN, FULLDSN, or FULLRECDSN if specified. If the threshold specified for OUTSIZE is met or exceeded, the image copy output will go to an alternate set of DDs that are specified with the following keywords, which are described in the BMC AMI Copy for Db2 documentation

  • BIGDDN
  • BIGDSN
  • BIGRECDDN
  • BIGRECDSN

OUTSIZE requires the use of dynamic allocation and can be used with any FULL option. The size of the copy is based on the size of a full copy.

If you do not specify OUTSIZE with the OPTIONS command, Online Consistent Copy uses the value of the BMC AMI Copy OUTSIZE installation option as the default.
