DB2 Connect Quick Beginnings for UNIX**

Updating HP-UX Kernel Configuration Parameters

Before installing your DB2 Connect for HP-UX product using db2setup or swinstall, you may need to update your system's kernel configuration parameters. The values in Table 6 are the recommended HP-UX kernel configuration parameters.
Note: You must reboot your machine after updating any kernel configuration parameters.

Table 6. HP-UX Kernel Configuration Parameters (Recommended Values)

Kernel Parameter Physical Memory

maxuprc maxfiles nproc nflocks ninode nfile msgseg msgmnb msgmax msgtql msgmap msgmni msgssz semmni semmap semmns semmnu shmmax shmseg shmmni	256 256 512 2048 512 (4 * ninode) 8192 65535 (2) 65535 (2) 256 130 128 16 128 130 256 256 67108864 16 300	384 256 768 4096 1024 (4 * ninode) 16384 65535 (2) 65535 (2) 512 258 256 16 256 258 512 512 134217728 (3) 16 300	512 256 1024 8192 2048 (4 * ninode) 32767(1) 65535 (2) 65535 (2) 1024 258 256 16 512 514 1024 1024 268435456 (3) 16 300

Notes:

The msgsem parameter must be set no higher than 32767.
The msgmnb and msgmax parameters must be set to at least 65 535.
The shmmax parameter should be set to 134 217 728 or 90% of the physical memory (in bytes), whichever is higher. For example, if you have 196 MB of physical memory in your system, set shmmax to 184968806 (196*1024*1024*0.9).
To maintain the interdependency among kernel parameters, change parameters in the same sequence in which they appear in the preceding table.

To change a value, perform the following steps:

Step  1.
Enter the SAM command to start the System Administration Manager (SAM) program.
Step  2.
Double-click on the Kernel Configuration icon.
Step  3.
Double-click on the Configurable Parameters icon.
Step  4.
Double-click on the parameter that you want to change and enter the new value in the Formula/Value field.
Step  5.
Click on OK.
Step  6.
Repeat these steps for all of the kernel configuration parameters that you want to change.
Step  7.
When you are finished setting all of the kernel configuration parameters, select Action --> Process New Kernel from the action menu bar.
The HP-UX operating system automatically reboots after you change the values for the kernel configuration parameters.
