DATACO

Use the DATACO macro to specify values for the data reduction pre-compiler segment (JPC0) that is used to compile the other data reduction segments. See z/TPF System Performance and Measurement Reference for information about the preprocessor statements in segment JPC0.
Note: The z/TPF data collection and reduction package does not use these values. This macro is available for you to use for your own data reduction code if required.

INTVL=300|n
The number of sampling intervals for the life of Data Collection in the continuous mode. Also, the maximum number of sampling periods for the life of Data Collection in the sampling mode. INTVL may not exceed 300; it must be greater than 0.
WT=5|n
Weighting factor to be applied to low-speed messages. This is the number of high-speed messages that is equivalent to one low-speed message.
WT2=3|n
Weighting factor to be applied to routed messages. Valid ranges of WT2 values are 1 to 9. Note these values will generate a definition containing a decimal point (i.e., 3 will be generated as .3).
CIT=35|n
Specifies the maximum number of cities in the system that are associated with an interchange address.
TMC=700|n
Specifies the maximum number of terminals per city.
IAC=30|n
Specifies the maximum number of interchange addresses per city. The maximum allowable is 32. The minimum is 1.
IAS=30|n
Maximum number of unique LN (lines) and IA's (interchange addresses) in the system. The minimum value is 1.
PGMS=600|n
Number of programs to be reported. The minimum value is 1.
TNODS=10000|n
Specifies the total number of resources (both local and nonlocal) in the network. This number must be equal to or greater than the number declared for the MAXRVT keyword of the SNAKEY macro coded at network definition time.
NPGM= 35|n
Specifies the number of program names that can be placed in the SM record on the RTC tape. The value specified must be from 1 to 63.
USERN='Z/TPF TRANSACTION CENTER'|xxxx
A 1–25 character name describing the user for which the report is being produced. If blanks are part of the character string, enclose the name in single quotation marks..
RECID=100|n
Maximum number of unique pool and fixed record IDs (byte 1 and 2 of record) for data to trace. The minimum value is 2 and the maximum is 500.
SKIP=99|n
Sets the default value for the skip parameter on the ZMEAS command. The minimum value is 0 and the maximum is 9999. See the description of the ZMEAS skip parameter in z/TPF Operations for more information.

Entry requirements

You can code this macro only when generating a base-only system, or when generating the basic subsystem in a multiple database function (MDBF) environment.

Return conditions

None.

Programming considerations

None.

Examples

The following shows the DATACO macro for a system whose report heading is to be TPF TEST CENTER with 200 sampling intervals, 50 terminals per city, and a default value of 0 for the skip parameter on the ZMEAS command. All other options default. 
DATACO INTVL=200,USERN='TPF TEST CENTER',TMC=50,SKIP=0
