UPDATE_SOLARIS_KERNEL.

•LINUX USERS: Running DB2 on a Linux 2.4 server requires changes to the Linux kernel parameters. Recompile the kernel source as explained below before you install DB2 on the server.

•Change the msgmni parameter to 256 with the following command: echo 256 > /proc/sys/kernel/msgmni

This resets the maximum number of SYSV IPC message queues from the default of 16 to 256.

•Increase SEMMNI from 128 to 2048.

This specifies the maximum number of semaphore IDs allowed in the kernel; the upper limit for this value is 32768.

•Increase SEMMSL from 250 to 500.

This specifies the maximum number of semaphores per sem ID; the upper limit for this value is 8000.

•Increase SEMOPM from 32 to 256.

This specifies the maximum number of operations allowed per semop() call; the upper limit for this value is 1000.

•Increase the number of open files using the command: echo 32768 > /proc/sys/fs/file-max
