Linux on IBM eServer zSeries and S/390: Performance Toolkit for VM

Chapter 10. Performance Toolkit for VM updates for function level 510 197

4. OPTION QUICKDSP also ensures that Performance Toolkit for VM will be

dispatched long enough.

5. The LINKs to 5VMPTK10 minidisks provide access to the control files and

executable parts of Performance Toolkit for VM.

6. The MDISK 191 defines the PERFSVM machine’s A-disk.

7. The MDISK 195 defines a disk on which history data can be saved.

The PROFILE EXECSAMP has also been updated to reflect the changes to the

minidisks that are used for the control files.

10.3 Control file changes for FL510

The files that are necessary to control Performance Toolkit for VM are located on

5VMPTK10 users 1CC disk. These can be modified and kept on the 1CC disk for

local tailoring. The latest serviced copy of each is kept on the 2C2 disk. For any

permanent changes to control files, you should use the VMSES/E local

modification instructions found in Guide for Automated Installation and Service,

SC24-6099. This will create an update on the 2C4 disc and alert you when

service is applied to a control file. The 1CC disk will be used by the PERFSVM

machine.

10.3.1 FCONX $PROFILE change

The FCONX $PROFILE file contains Performance Toolkit for VM commands to

set up and control how the Performance Toolkit for VM will operate. The FC

MONCOLL RESET command has been changed to reflect the new summary file

creation similar to VMPRF SUMMARY files. You can now use S as a suffix to tell

PERFKIT to create a summary file at the specified time. You can specify all (P, T,

and S — print, trend, and summary) at one time or use a separate set of times for

each. See Figure 10-3 on page 199 for an example.

10.3.2 Performance Toolkit for VM report changes

Changes have been made to these Linux reports:

򐂰 LXCPU

򐂰 LXNET

򐂰 LXPROC

They can be entered without specifying a user ID. This produces the new screen

with an entry for each Linux user ID that is producing APPLDATA. From these

new screens you can now select more details by user ID. See 10.5, “Using

APPLDATA from Linux” on page 200 for more details.
