CHK SYMBLP

Under the Full Checking technique, PCP can validate symbolic logical parent (LP) pointers if they meet all of the following conditions:

  • The target is a root segment.
  • The target key is not compressed.
  • There is no equivalent direct pointer to get to the target.

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

Use the CHK SYMBLP 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 SYMBLP option at the following levels:

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