To run DB2 for Solaris, you may have to update some kernel configuration
parameters; the following minimum values are recommended:
Table 46. Solaris Kernel Configuration Parameters (Recommended Values)
Kernel Parameter | Physical Memory | |||
---|---|---|---|---|
64MB - 128MB | 128MB - 256MB | 256MB - 512MB | 512MB+ | |

Notes:
To set a kernel parameter, add a line at the end of the /etc/system file as follows:
set parameter_name = value
For example, to set the value of the msgsys:msginfo_msgmax parameter, add the following line to the end of the /etc/system file:
set msgsys:msginfo_msgmax = 65535
Sample files for updating the kernel configuration parameters are provided in the /opt/IBMdb2/V5.0/cfg directory. The names for these files are as follows:
Depending upon the amount of physical memory in your system, append the appropriate kernel configuration parameter file to the /etc/system file. If necessary, change the value of the shmsys:shminfo_shmmax parameter as described in Note 2 above.
After updating the /etc/system file, reboot the system.
