Additional Post-Install Instructions for KMP*4.0*1:
 
Some sites experienced performance issues after the install of this patch 
associated with the ^PERFMON utility running.  Although it is a useful 
diagnostic, ^PERFMON should not be routinely running on any system.
 
-       The following will need to be done by a member of the Health 
Systems team (or someone with access to %SYS) on each system with the 
patch installed:
o       This step needs to be done on each server - each front-end, each 
back-end, and each failover member
o       From %SYS: D ^PERFMON
o       If you see "Monitor is Stopped" PERFMON is not running this step 
is complete
o       Otherwise, use 2. Stop Monitor to stop PERFMON
 
-       The following will need to be done by a member of the VAD Kernel 
team (or someone with access to file #8969).  Note: This step needs to be 
done **after** the installation of KMP*4.0*1 but before midnight on the 
day of install.
o       Edit each of the VSM Configuration file (#8969) records and 
change/view the START PERFMON field (#1.08) 
o       If the field is "False", this step is complete
o       Otherwise, Change the START PERFMON field (#1.08) set to False if 
this is not already the case.
 
>> Do not proceed unless you are confident of these steps.  Example
 
Example where PERFMON is off:
%SYS>D ^PERFMON
 
 
1. Start Monitor
2. Stop Monitor
3. Pause Monitor
4. Resume Monitor
5. Sample Counters
6. Clear Counters
7. Report Statistics
8. Timed Collect & Report
 
Monitor is Stopped
 
Example where PERFMON is on and needs to be stopped:
 
%SYS>D ^PERFMON
 
 
 
1. Start Monitor
2. Stop Monitor
3. Pause Monitor
4. Resume Monitor
5. Sample Counters
6. Clear Counters
7. Report Statistics
8. Timed Collect & Report

1. Start Monitor
2. Stop Monitor
3. Pause Monitor
4. Resume Monitor
5. Sample Counters

Example of Changing /Verifying START PERFMON field (#1.08) set to False:
 
Select OPTION: 1  ENTER OR EDIT FILE ENTRIES
 
 
 
Input to what File: BUILD// 8969  VSM CONFIGURATION  (7 entries)
EDIT WHICH FIELD: ALL// 1.08  START PERFMON
THEN EDIT FIELD: 
 
 
Select VSM CONFIGURATION MONITOR KEY: ^LOOP
EDIT ENTRIES by: MONITOR KEY// 
Start with MONITOR KEY: FIRST// 
 
   VBEM
START PERFMON: True// F  False
 
   VCSM
START PERFMON: True// F  False
 
   VETM
START PERFMON: True// F  False
 
   VHLM
START PERFMON: True// F  False
 
   VMCM
START PERFMON: True// F  False
 
   VSTM
START PERFMON: True// F  False
 
   VTCM
START PERFMON: True// F  False
 
    LOOP ENDED!
 
The above can be used to confirm that START PERMON is set correctly.
