Use the CTRACE parameter in GRSCNFxx to specify the CTRACE options you want for your installation. For more information about global resource serialization component trace, see z/OS MVS Diagnosis: Tools and Service Aids. For information about how to specify the options you want, see z/OS MVS Initialization and Tuning Reference.

The CTRACE parameter in GRSCNFxx allows you to modify the default tracing options used by global resource serialization. Because the defaults provide adequate serviceability information, you should change them only upon the recommendation of your IBM® service representative.

The CTRACE parameter in GRSCNFxx is available only in systems running MVS/SP Version 4 or later.
