Kernel Tuning

Yajuvendra Singh — Tue, 03 Jan 2006 01:38:43 GMT

Dear All,

I am failing to Install an application because of maxdsiz. My current value is 2 pages I want to make maximum using command.

I am having c8000 series hp-ux 11.11i machine. I went throught SAM and found that values are not in Pages. How to change this maxdsiz from 2 pages to 65536 pages.

Please help me sort it out. Thanks in advance.

Regards,
Yajuvendra Singh

maxdsiz is varying in bytes not by pages. Look at this,

When Should the Value of This Tunable Be Raised?

This tunable should be raised if user processes are receiving the ENOMEM error message:

exec(2): data exceeds maxdsiz

or

exec(2): data exceeds maxdsiz_64bit.

This may or may not cause a process failure depending on the program code.
