The variable field is defined as follows:

rdovffs
Specifies the percentage of free space in the dependent overflow area in each UOW. If the free space percentage in the dependent overflow area in a UOW is greater than the specified percentage, and the UOW also uses IOVF CIs, the UOW is selected as a candidate for the reorganization.

Specify an integer value in the range of 0 - 100. The maximum value 100 has a special meaning; if RDOVFFS=100 is specified, the RDOVFFS condition is not used to select an initial set of UOWs.

For details of how the number of UOWs to be reorganized is determined, see The number of UOWs to be reorganized.

Default:
0, if the RDOVFFS keyword is not specified.
Site default support:
Not supported.
Important: If the name of the IMS Tools KB server XCF group is specified on the ITKBSRVR keyword, and if the RDOVFFS keyword is not specified, the utility reads the value of data element DB_THRESHOLD_RDOVFFS from the Sensor Data repository of the specified IMS Tools KB server and uses it as the value of the RDOVFFS keyword.
To store this value in the IMS Tools KB repository with DB Sensor, add the following keyword in the JCL for use with DB Sensor:
  • For the OPC utility with DB Sensor, specify the EXC_RDOVFFS keyword in the FPXIN DD. For more information, see EXC_RDOVFFS keyword.
  • For stand-alone DB Sensor, specify the RDOVFFS keyword in the HFPAPARM DD. For more information, see the IMS Solution Packs Data Sensor User's Guide.
  • For FPA Analyze with DB Sensor, specify the RDOVFFS keyword in the HFPAPARM DD. For more information, see DD statements for the Analyze function.
