Control File Size

The default RECORDSIZE value for the Control File should be large enough when you first implement CA Compress. But if you intend to generate an FDT with an RDL specification using all three Huffman tables (C1, C2, and C3), you must increase the RECORDSIZE. The RECORDSIZE value can be from 1-6 KB, depending on your installation.

The default CYLINDERS value for the Control File should also be large enough when you first implement CA Compress. As you bring more VSAM data sets and FDTs under CA Compress control, you may need to increase the CYLINDERS value.
