Identifying the Subsystem Function Routine z/OS MVS Using the Subsystem Interface SA38-0679-00 |
|
To identify the subsystem function routine, check the VRA. It contains the address of the failing routine. Identify the failing function routine by browsing backward in storage to find an eyecatcher. The information in the eyecatcher should also help identify the product with which the failing subsystem and function routine are associated. Note: The high-order bit of the function routine address
in the VRA or SSVT indicates the AMODE in which the routine receives
control. When the high-order bit is set, the SSI passes control to
the function routine in AMODE 31.
