DB2 Connect Quick Beginnings for UNIX**

Updating Solaris kernel configuration parameters

Before installing your DB2 Connect for Solaris product using the db2setup utility or the db2_install and pkgadd commands, you may need to update your system's kernel configuration parameters. The values in Table 8 are the recommended Solaris kernel configuration parameters.

Note:

You must reboot your machine after updating any kernel configuration parameters.

Table 8. Solaris Kernel Configuration Parameters (Recommended Values)

Kernel Parameter	Physical Memory
	64MB - 128MB	128MB - 256MB	256MB - 512MB	512MB+
msgsys:msginfo_msgmax msgsys:msginfo_msgmnb msgsys:msginfo_msgmap msgsys:msginfo_msgmni msgsys:msginfo_msgssz msgsys:msginfo_msgtql msgsys:msginfo_msgseg shmsys:shminfo_shmmax shmsys:shminfo_shmseg shmsys:shminfo_shmmni semsys:seminfo_semmni semsys:seminfo_semmap semsys:seminfo_semmns semsys:seminfo_semmnu semsys:seminfo_semume	65535(1) 65535(1) 130 128 16 256 8192 67108864 50 300 128 130 256 256 50	65535(1) 65535(1) 258 256 16 512 16384 134217728(2) 50 300 256 258 512 512 50	65535(1) 65535(1) 258 256 16 1024 32767(2) 268435456(3) 50 300 512 514 1024 1024 50	65535(1) 65535(1) 258 256 16 1024 32767(2) 536870912(3) 50 300 1024 1026 2048 2048 50

Notes:

1. The msgsys:msginfo_msgmnb and msgsys:msginfo_msgmax parameters must be set to 65535 or larger.

2. The msgsys:msgsem parameter must be set no higher than 32767.

3. The shmsys:shminfo_shmmax parameters should be set to the suggested value in the above table, 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 the shmsys:shminfo_shmmax parameter to 184968806 (196*1024*1024*0.9).

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/V7.1/cfg directory, or on your DB2 product CD-ROM in the /db2/install/samples directory. The names for these files are as follows:

kernel.param.64MB

for systems with 64MB-128MB of physical memory

kernel.param.128MB

for systems with 128MB-256MB of physical memory

kernel.param.256MB

for systems with 256MB-512MB of physical memory

kernel.param.512MB

for systems with 512MB-1GB of physical memory

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.
