Adjusting operating system parameters for Solaris

In order for DB2 Everyplace to operate with the highest degree of efficiency, system parameters in DB2 Universal Database need to be adjusted. Failure to do so, can result in unexpected interruptions. It is recommended that the kernel parameters are adjusted.

Note:: Only 32 bit DB2 Universal Database instances are supported.

Prerequisites

Modify the login profile to include the following:

export DISPLAY=<workstation>:0.0

Where <workstation> is the UNIX workstation where you want to use the Mobile Device Administration Center.

Procedure

For Solaris systems, the default system kernel parameters are insufficient to run DB2 Universal Database and DB2 Everyplace. These values can be added or edited in the file, /etc/system.

The format for setting these values is:

set parameter_name = value

The suggested parameters in the DB2 Universal Database should be further adjusted to include the following minimum values:

set shmsys:shminfo_shmseg = 256
set semsys:seminfo_semume = 256

After modification of any kernel parameters, reboot the system to make the kernel settings effective.
