Oracle Database 11.2.0.2 tcp_ and udp_ New kernel parameters for Sun Solaris 10

There are some new kernel parameters needs to be configured in order to Install new patch set for 11gR2 (11.2.0.2)

Error message while running Installer:

PRVF-7543 : OS Kernel parameter “tcp_smallest_anon_port” does not have proper value on node “solaris1″ [Expected = "9000" ; Found = "32768"]
PRVF-7543 : OS Kernel parameter “tcp_largest_anon_port” does not have proper value on node “solaris1″ [Expected = "65500" ; Found = "65535"]
PRVF-7543 : OS Kernel parameter “udp_smallest_anon_port” does not have proper value on node “solaris1″ [Expected = "9000" ; Found = "32768"]
PRVF-7543 : OS Kernel parameter “udp_largest_anon_port” does not have proper value on node “solaris1″ [Expected = "65500" ; Found = "65535"]

The following are the list of parameters:

1) tcp_smallest_anon_port

2) tcp_largest_anon_port

3) udp_smallest_anon_port

4) udp_largest_anon_port

When i was trying to Install this new patchset, the result for pre-requisite check was failed because of these newly introduces kernel parameters.

These kernel parameters was not updated in Installation and upgrade guide for solaris at the time when i was installing:

Setting these kernel parameters:

1) To view the current value of these parameters, login as root user:

bash-3.00#  ndd /dev/tcp tcp_smallest_anon_port tcp_largest_anon_port
9000

65500
bash-3.00#

bash-3.00# ndd /dev/udp udp_smallest_anon_port udp_largest_anon_port
9000

65500
bash-3.00#

The kernel parameters as expected by the Installer:

kernel parameter preset val expected

tcp_smallest_anon_port -- 32768 --> 9000

tcp_largest_anon_port -- 65535 --> 65500

udp_smallest_anon_port -- 32768 --> 9000

udp_largest_anon_port -- 65535 --> 65500

update these kernel parameters using following parameters:

bash-3.00# ndd -set /dev/tcp tcp_largest_anon_port 65535
bash-3.00# ndd -set /dev/udp udp_smallest_anon_port 9000
bash-3.00# ndd -set /dev/udp udp_largest_anon_port 65500
bash-3.00# ndd -set /dev/tcp tcp_smallest_anon_port 9000
bash-3.00# ndd -set /dev/tcp tcp_largest_anon_port 65500

Then verify the settings using:

bash-3.00#  ndd /dev/tcp tcp_smallest_anon_port tcp_largest_anon_port

bash-3.00# ndd /dev/udp udp_smallest_anon_port udp_largest_anon_port

After setting these kernel parameters the pre-requisite check was successfull and Installation completed without any issue.

Happy reading.
