System parameters are specified by means of an extrapartition transient data queue with a destination ID of COPR. The parameters may be assigned to a DD * file, sequential data set, or a partitioned data set member. The DD name for the extrapartition transient data queue is EYUPARM.
The parameters are coded as 80-byte records. Multiple system parameters can be specified on a single record as long as they are separated by commas and do not exceed 71 characters in length. The format of a system parameter is:
keyword(value)
where:
There are two types of problem determination parameters for each CMAS or MAS component. The parameters are named as follows, where xxx is the 3-character component identifier:
For the trace and message parameters shown here, you can specify one or more values between 1 and 32. Values of 1 and 2 provide standard trace entries and messages; values of 3 through 32 cause special trace entries and messages to be recorded.
You can specify multiple values on a single parameter. To specify individual values, separate the values with a comma. To specify a range of values, separate the low and high values with a colon. For example:
KNLTRACE(1:3,16,28:32)
turns on trace levels 1 through 3, 16, and 28 through 32 in the Kernel Linkage (KNL) component.
To request multiple values for the same parameter, you must specify them as a single entry. If the same parameter is specified more than once, only the last entry is used.
