Deciding Which Resources to Process

The best way to decide what resources GDIF, ECMF, or both should process is to activate GDIF, ECMF, or both to monitor resource activity through the CA MII display counts commands, and then reevaluate the QNAME list. Most sites can use the sample QNAME list provided in the MIMQNAME member to test the processing of GDIF and ECMF. Review the following guidelines when choosing QNAMEs that GDIF and ECMF should process:

• The resources in that class are used on more than one system.
• All ENQ and RESERVE requests for a specific resource use the same RNAME.
• RESERVE requests for that QNAME (if any) are long enough to degrade system performance if they are not propagated as global ENQ requests. In general, you should not place a QNAME in the QNAME list if its RESERVE requests are short.

For QNAMEs used by vendor-supplied software, you should contact the vendor for specific recommendations about QNAMEs and resources used by the product.
