Oracle parameters installation

[Former Member]

Hi,

I want to install the software client of oracle on unix and one of the prerequiste check is with warning:

Checking security kernel parameters

Checking for BIT_SIZE=64; found BIT_SIZE=64. Passed

Checking for shmsys:shminfo_shmmax=4294967295; found no entry. Failed <<<<

Checking for shmsys:shminfo_shmmni=100; found no entry. Failed <<<<

Checking for semsys:seminfo_semmni=100; found no entry. Failed <<<<

Checking for semsys:seminfo_semmsl=256; found no entry. Failed <<<<

Check complete. The overall result of this check is: Failed <<<<

Problem: The security parameters in the kernel do not meet the minimum requirements (see above).

Recommendation: Perform operating system specific instructions to update the kernel parameters, namely BIT_SIZE and noexec_user_stack.

What can I do?

Hi Ruben,

Which OS you are using, if its HP-UX, then in installation guide, you can check the topic "Checking and Modifying the HP-UX Kernel" for modifying the kernel parameters.

Also run the Prerequisite Checker, so that you can know if any thing is missing.

Hi Ruben,

What kind of UNIX/Linux OS are you using? I think you have to change some kernel parameter.

If you are using Linux, here is an example in order that can help you in order to find the right values:

edit /etc/sysctl.conf and add the following lines:

> kernel.shmall = 2097152

> kernel.shmmax = 2147483648

> kernel.shmmni = 4096

> kernel.sem = 250 32000 100 128

> fs.file-max = 65536

after that type "sysctl u2013p" and start again your installation.

I guess you're talking about installing the oracle client. If so kindly follow SAP Note :819829
