CHK PHYPAIR

While validating logical pointers, PCP always validates that every physically paired logical child segment has its paired counterpart, provided that the logical child segments have direct logical parent and physical parent pointers.

Under the Full Checking technique, PCP can also validate that paired logical segments have identical fixed intersection data. This validation is possible only if the logical child segments are defined as fixed-length and are not compressed. If the fixed intersection data is larger than 252 bytes, only the first 252 bytes are used.

This validation requires additional sort work areas (SYMBWKnn), which PCP dynamically allocates if you omit the DD statements.

Use the CHK PHYPAIR option to control whether PCP performs this validation.

Note

This option is not available when you use the Hash Checking technique.

Uses

You can set the CHK PHYPAIR option at the following levels:

  • Global options module
  • Generated JCL
  • GLBL control statement
  • CHECK control statement
