Runtime environment definition (RTEDEF) library

A runtime environment definition is a set of parameters. Parameters are stored in a runtime environment definition (RTEDEF) library. The set of parameters for each runtime environment is organized into several RTEDEF members.

The data set name of the RTEDEF library consists of the high-level qualifiers that you specify to IBM Z® Monitoring Configuration Manager in the RTE_PLIB_HILEV workflow variable in the KCIVARS input data set, followed by the fixed low-level qualifier RTEDEF:

rte_plib_hilev.RTEDEF

You can allocate the RTEDEF library yourself or you can use the CREATE action to allocate it and populate it with initial members for you.

An RTEDEF library can contain multiple runtime environment definitions. A single RTEDEF library can contain all of the runtime environment definitions for a sysplex. Or you can choose to store each runtime environment definition in a separate RTEDEF library.

If you are going to set up a High Availability TEMS (HA TEMS), make sure there is only one runtime environment defined in the RTEDEF (that is, the one used for the HA TEMS).

RTEDEF library members are also known as configuration profile members.
