Extend IOVF for Offline EXTEND command
Before executing this control statement, you must ensure that adequate space is present on the primary volume of the target area data set to accommodate the request for additional UOWs.
If the necessary space is not present, allocate volumes to the area data set by using IDCAMS ALTER ADDVOLUME.

01-04 | EXEC and STEPLIB DD statements for Fast Path/EP offline execution. |
05 | IMSACB DD statement used for database processing. |
06 | PFPSYSIN DD for Fast Path/EP control statements. |
07 | Area PFPSAMP1 is identified on the EXTEND statement, and is dynamically allocated from its dynamic allocation member in the IMSVS. DFSMDA data set in the STEPLIB concatenation. |
08 | If you have a license for the BMC Fast Path Analyzer/EP product, quick (checksum) pointer validation is performed on area PFPSAMP1 by default. This pointer validation is performed by default, even if you do not specify it explicitly. |
09 | Adding 50 units of work to IOVF increases space for IOVF. Increasing space in this manner allows you to perform a DBD change of the UOW value at a later time. |
10-11 | During the area extend, an output image copy is taken simultaneously using standard storage and disposition parameters. The DBD and area name are substituted in the image copy data set name to create a unique name for each area. |
