Specifying the information level

The Accounting and Measurement Data Area (IXLYAMDA) supports several levels of information that IXLMG returns. Certain coupling facility and structure requests might provide data that was not returned when the IXLMG service was first made available. For these request types, you can specify the level of information you want with the AMDALEVEL parameter on IXLMG. The AMDALEVEL parameter is available with version 1 of the IXLMG macro. The system returns base AMDA information when you specify AMDALEVEL=0 on your request; the system returns level n AMDA information when you specify AMDALEVEL=n on your request. Be aware of the type of output that you are requesting and be able to process it correctly. Specifying a larger level might result in larger IXLYAMDA records.

The list in Types of information available lists the IXLYAMDA mappings that support the various levels of IXLYAMDA information. A structure name to which a number is appended will contain all the information contained in the lower-level structures plus, optionally, additional information pertaining to the information request type. See the IXLYAMDA macro in z/OS MVS Data Areas in the z/OS Internet library for a description of the information returned.
