In order to use the Dashboard Server, you must first tune the system parameters for the common resources that the individual pieces of software will use. The following chart shows the system parameters that need to be tuned and the values for each. In some cases values need to be added to existing (default) values, while in other cases two values are compared and the highest (maximum) of the two is used. (Be sure to check system upper limits when adding values.) The "Type" column in the tables below tells you which method is used for each of the values.
Refer to Solaris and Linux manuals for further details.
For Solaris
The Dashboard Server runs under the following projects:
system project
Project where daemons, etc., that exist in the operating system's default state, operate
user.root project
Project where processes that operate with root rights, in the operating system's default state, are located
Parameters | Description | Value | Type | Privileges |
|---|---|---|---|---|
project.max-shm-memory | Maximum size of shared memory segment | 108388350 | Add | Privilege level |
project.max-shm-ids | Maximum number of shared memory identifiers | 70 | Add | Privilege level |
Parameters | Description | Value | Type | Privileges |
|---|---|---|---|---|
project.max-sem-ids | Number of semaphore identifiers | 1468 | Add | Privilege level |
process.max-sem-nsems | Maximum number of semaphores per semaphore identifier | 512 | Maximum | Privilege level |
process.max-sem-ops | Maximum number of operations at each semaphore call | 50 | Maximum | Privilege level |
Parameters | Description | Value | Type | Privileges |
|---|---|---|---|---|
process.max-msg-qbytes | Maximum number of bytes in queue | 65536 | Maximum | Privilege level |
project.max-msg-ids | Number of message waiting identifiers | 529 | Add | Privilege level |
process.max-msg-messages | Maximum number of messages in message queue | 1024 | Add | Privilege level |
Point
Specify "privileged" in the /etc/project file to set the privilege level.
Edit the /etc/project file to tune the system parameters.
Note
Before setting system parameters, first confirm the initial values of the system and the upper limits of the values that can be set. The following is an example of how to check these values:
Use the following command to check the values currently set on the system for the relevant parameters in the above table:
# projects -l
Confirmation command execution example:
# projects -l system projid : 0 comment: "System account" users : (none) groups : (none) attribs: user.root projid : 1 comment: "root user" users : root groups : root attribs: noproject projid : 2 comment: "" users : (none) groups : (none) attribs: default projid : 3 comment: "Default project setting" users : (none) groups : (none) attribs: # newtask -p default # prctl $$ process: 1000: sh NAME PRIVILEGE VALUE FLAG ACTION RECIPIENT process.max-port-events privileged 65.5K - deny - system 2.15G max deny - process.max-msg-messages privileged 8.19K - deny - system 4.29G max deny - system 16.8M max deny - *
Refer to the "Tuning values of system parameters" table (above), compare the values in the table to the current system parameter values and then calculate the appropriate values, taking into account the type (either maximum or add), for each parameter. Edit the /etc/system file based on the results of these calculations.
Note
Put each value on its own line for each project.
Make the settings for tuning the parameters for both the system and the superuser.
After making the above settings, use the following command to check the settings.
# projects -l
Confirmation command execution example:
# projects -l

Edit the /etc/sysctl.conf file to tune the system parameters.
Use the following command to check the values currently set on the system for the relevant parameters in the above table:
#/sbin/sysctl -a
Refer to the "Tuning values of system parameters" table (above), compare the values in the table to the current values and then calculate the appropriate values, taking into account the type (either maximum or add), for each parameter.
Edit /etc/sysctl.conf.
Tune the system parameters by editing the /etc/sysctl.conf file based on the results calculated in step 2.
Use the following command to confirm that the changes you made to /etc/sysctl.conf were saved in the file:
#/bin/cat /etc/sysctl.conf
Do one of the following to put the above settings into effect:
Method 1: Restart system to make the settings effective
# cd / # /sbin/shutdown -r now
Method 2: Use /sbin/sysctl -p to make the settings effective
# /sbin/sysctl -p /etc/sysctl.conf
Use the output from the following command to confirm that the changes made to the system parameters were implemented:
# /sbin/sysctl -a
Confirmation command execution example:
# /sbin/sysctl -a
