Some functionality of CA Mainframe Application Tuner requires ERBSMFI:
Obtaining SMF record data directly
z/OS RMF Programmer's Guide
Programming Interface information
The RMF data interface service for Monitor II allows you to directly access
SMF record data from storage in real time, rather than through SMF. Application
programs can easily access SMF record data. The service provides easy access
to SMF data for application programs. SMF record type 79, and the Monitor
II header information for system CPU utilization and system demand paging
rate, are supported.
To use the RMF data interface service, invoke the module ERBSMFI with the
registers and parameters described in Parameter list contents.
Do not link the module ERBSMFI into your application
program. Code the program to call ERBSMFI at run time. How to do this depends
on the programming language you use:
In Assembler, use LOAD or LINK macros
In PL/I, use FETCH and RELEASE
In C, use the fetch built-in function
The service returns only one record to the caller,
which contains all the data. There is no 32K size limit; that is, the record
is not broken up into 32K records.
The caller must be in 31-bit addressing mode and can run unauthorized.
Note that for some of the records, Monitor I must be running. These are
Subtype 9 - Device activity
Subtype 11 - Paging activity
Subtype 14 - I/O queuing activity
For more information about SMF record type 79, see SMF record type 79.
CA MAT is making use of this IBM module, and it resides in that load library that you needed to point to.
