tunable parameter

[Roro_2]

Hello,

Our customer had an ES40 server running Tru64 Unix 5.1 ; the Oracle DBA requested the modification of the tunable parameter "new_wire_method" from the default value 1 to 0.
But i read a notice about this parameter that it is for internal use only and we should not modify it.

Please advise.

Regards

Roger

There have been several topic addressing this before. Google for:

+new_wire_method +site:itrc.hp.com

Add +hein for the good stuff :-)

Notably check:

And

http://alpha-supernova.dev.filibeto.org/lib/misc/tuning/tuning-tru64-oracle.pdf

Unfortunately I could (quickly) not find an .HP.COM address for that critical document.

I googled for its title and it pointed to an interesting page:

google: "Tuning HP Tru64 UNIX V5.1A and V5.1B for Oracle Environments"

There are certain combinations of Tru64 UNIX version and patch kit, and Oracle version, for which turning off new_wire_method is beneficial and recommended. This is particularly true for older versions of Tru64. If the Oracle DBA recommends turning it off, I would have no hesitation in doing so. Turning it off will not harm anything in the operating system.
