G.1 List of Kernel Parameters (in HP-UX)
- Organization of this subsection
(1) Adjusting the Default System Resource Settings
The table below shows the estimated values for the default system resource settings that need to be adjusted to run JP1/Base.
(a) Parameters to be added
System resource |
Parameter |
Estimate |
---|---|---|
Process |
nproc |
|
|
||
|
#: If using the JP1/SES compatibility function, estimate the value for this parameter as indicated in Appendix G.1(4) When using the JP1/SES compatibility function.
If you are using a logical host, for the nproc parameters, base your estimate on the number of commands executed concurrently on the computer as a whole (logical host and physical host).
(b) Parameters to be adjusted
System resource |
Parameter |
Estimate |
---|---|---|
File system |
maxfiles |
Number of hosts managed by the local host in a system using JP1/IM - Manager# + 60 |
#: Required only when using JP1/IM - Manager.
If you are using a logical host, for the maxfiles parameter, base your estimate on whichever host (logical host or physical host) manages the largest number of hosts.
(2) When using the command execution function
The tables below show the estimated values for the kernel parameters that need to be adjusted to run JP1/Base when using remote commands and automated actions issued from JP1/IM - Manager.
(a) Parameters to be added
System resource |
Parameter |
Estimate |
---|---|---|
Process |
nproc |
(Number of concurrently executable remote commands + Number of concurrently executable automated actions#1) × 3#2 + Number of Execute Command windows#3, #4 |
maxdsiz |
67,108,864 or greater (64 MB or greater)#5 |
|
Shared memory |
shmmni |
1 + (Number of concurrently executable remote commands + Number of concurrently executable automated actions#1)#6 |
Semaphore |
semmni |
3 |
semmns |
3 |
|
semmnu |
(Number of concurrently executable remote commands + Number of concurrently executable automated actions#1) × 3#2 + Number of Execute Command windows#3, #4 |
- #1:
-
The default is 1. The estimate can be increased to a maximum of 48 by adjusting the value in the jcocmddef command.
- #2:
-
Three processes are generated by each remote command or automated action. Take these processes into account when estimating the number of remote commands and automated actions. When processing finishes, the process disappears. Multiple processes may
be generated if two or more commands are executed in succession. Estimate this value for the host specified as the command execution host.
- #3:
-
The number of Execute Command windows opened by the connected JP1/IM - View. The number of processes increases according to the number of open windows. When an Execute Command window closes, the corresponding process disappears. Estimate this value for the manager hosts issuing commands.
- #4:
-
The number of Execute Command windows in JP1/IM - Manager is a maximum of 64.
- #5:
-
You may need to increase this estimate depending on environment settings such as the command queuing limit set in the jcocmddef command. If the following equation gives a value greater than 64 MB, set a value higher than that value.
7 × a × b (KB)
a: The number of commands that can be queued as specified in the jcocmddef command (0 to 65,535; default 1,024). For details about the jcocmddef command, see jcocmddef in 15. Commands.
b: The number of JP1/IM - Manager programs issuing automated actions
executed by JP1/Base. The number of queued commands is managed separately for each JP1/IM - Manager program issuing automated actions executed by JP1/Base. For example, if automated actions are executed from JP1/IM - Manager on the host running JP1/Base and from JP1/IM - Manager on another manager host, b will be 2.
- #6:
-
If the total estimate exceeds 256, assume 256 in the calculations. Estimate this value for the host on which commands are executed.
(b) Parameters to be adjusted
System resource |
Parameter |
Estimate |
---|---|---|
Shared memory |
shmmax |
143,468 or greater |
shmseg |
1 or greater |
|
Semaphore |
semume |
3 or greater |
(3) When using the health check function
The tables below show the estimated values for the system resource settings that need to be adjusted to run JP1/Base when using the JP1/Base health check function.
(a) Parameters to be added
System resource |
Parameter |
Estimate |
---|---|---|
Shared memory |
shmmni |
10 + 10 × Number of logical hosts |
(b) Parameters to be adjusted
System resource |
Parameter |
Estimate |
---|---|---|
Shared memory |
shmmax |
215,644 or greater |
shmseg |
10 or greater |
(4) When using the JP1/SES compatibility function
The tables below show the estimated values for the system resource settings that need to be adjusted to run JP1/Base when using the JP1/SES compatibility function.
Even if the JP1/SES compatibility functionality is not consciously used, you need to perform the necessary calculations using these estimations if the v5-unused flag is not set for the options parameter in the event server setting file (conf).
- Note:
-
If an overwrite installation is performed from JP1/Base version 7 or earlier, the v5-unused flag is not set.
