IBM s/390 manual 66 S/390 PID ThinkPad Enabled for S/390

may force Linux swapping and this has severe effects on FLEX-ES performance. Having gone to considerable expense to obtain a small S/390 (in the form of your ThinkPad/EFS), we suggest you use it only as a S/390. If you need to also run a Linux server, we suggest you obtain another machine.

Q:Should I purchase an Uninterruptable Power Supply (UPS) for use with my ThinkPad/EFS machine?

A:The ThinkPad battery provides, in effect, a UPS function. You might consider an external surge protector.

Q:How do I order a ThinkPad/EFS system? What if I am not a PID member?

A:You do not need to be a PID member to order a ThinkPad/EFS system (although you will not have access to AD CD-ROM systems). The FSI Web site has a list of their business partners.

Q:Where can I find documentation about the various FLEX-ES traces?

A:There are several FLEX-ES traces:

–The processor event trace is always active and uses a permanently defined circular buffer. It is intended only for FLEX-ES debugging and is not documented.

–The processor instruction trace uses the tracesize buffer you define in your system definition. It is intended for FLEX-ES debugging but might be useful to more sophisticated customers. It is minimally documented at present, but FSI intends to provide better documentation.

–Device traces, which are usually obtained with the devtrsnap command. These are not documented at present, but a user familiar with channel programming techniques might find these traces useful.

The traces are not well documented at this time.

Q:Are any modifications, PTFs, or SPEs required for OS/390 on EFS?

A:No.

Q:Are printer FCBs emulated?

A:Yes. FLEX-ES printer emulation supports the Load Forms Control Buffer channel command. The default FCB provides 66 lines at 6 lines/inch, with a “channel 1 punch” at line 3 and a “channel 12 punch” at line 64.

Q:Is a default 1403 carriage tape emulated?

A:Yes. It is set for 66 lines at 6 lines/inch, and has a channel 1 “punch” at line 3. There is no way to alter these settings.

Q:Are Token Ring and Ethernet equally supported?

A:No. (We were still researching this question at the time of writing.)

Q:Can I manage an ESCON director from an EFS system?

A:Not from a ThinkPad/EFS system!

Q:I am interested in using FLEX-ES remote resources for disks and tapes. Do I need a FLEX-ES license just to run the resource manager on remote systems?

A:Yes, you will need a FLEX-ES license for every system running the resource manager.
