PC Server System/390 Software Facilities

PC Server System/390 Software Facilities (Type 8641)

NOTE: Knowledge of System/390 and CP/370 architecture is essential to the proper use of these processor control functions. Information about System architecture is found in IBM Principles of Operation, GA22-7201.

VM/ESA and VSE/ESA use the same problem determination tools on the PC Server/390 for debugging 390 operating system and application problems as they do on 390 mainframe systems.

Standard OS/2 debugging tools can be used to assist with problems with the 390 environment on the PC Server/390 since many of the functions use OS/2 facilities and PC Server devices.

The 390 Processor Complex Programs als have the following tools for controlling and debugging the system.

390 Manual Operations	Provides the function of the 390 hardware console as
	on mainframe systems.

390 Status Window	Displays the processor status word (PSW) and current
	status on the 390 processor.

390 I/O Trace	Used to trace I/O request between the 390 processor
	and its I/O subsystem. The trace can be selected by
	device and can be written to an OS/2 file. It can also
	be displayed in a Presentation Manager window by selecting
	the 390 I/O trace icon. (See 'System/390 Icons').

Snap Shot Dump	Creates a binary file of the I/O subsystem to be used by IBM
	support personnel during problem determination. This program
	is selected by clicking on the Snap Shot Dump icon.
