Memory segment error.

[Abdullatif M abdulla]

thanks, but if I go back and ask about (Failed to get another shared memory segment (required size=100761552 bytes)

What does it mean by required size=100761552 bytes ? where is this required size?

@Dennis>> how do we find whether its using 32bit address space or 64 bit.
I could not find this out.

BR,

The application is trying to tell you the size it wants but didn't get.

>Kapil: how do we find whether its using 32bit address space or 64 bit.

You can do a file(1) on the executable, if 32 then it's 32. If 64, then you must use tusc to see if it wants to share a 32 bit address space, shmget(2) with IPC_SHARE32.

You can also look at the address to find if it is 32 or 64 bit.

Sample:

#file /oraprod/prod/oracle/product/805/bin/oracle
/oraprod/prod/oracle/product/805/bin/oracle: PA-RISC1.1 shared executable dynamically linked -not stripped

Can you tell from file() output it is 32 bit or 64 bit executable? What would be your guess on this executable?

PA1.1 can only do 32 bit mode. For more, see my reply here:

@Dennis:>PA1.1 can only do 32 bit mode.

What do you think about this:

# file /oraprod/prod/oracle/product/805/bin/oracle
/oraprod/prod/oracle/product/805/bin/oracle: PA-RISC1.1 shared executable dynamically linked -not stripped

# su - ora9prod

Strangely this didn't change, still 32. :-)

This claims to be 64 bit.

[Dennis Handly]

>Horia: getconf HW_CPU_SUPP_BITS -> 64

Since this always returns "black" (on Integrity or 11.23), it is a waste of time using it, unless you have 11.11 and an obsolete PA1.1 box or one that still allows a 32 bit kernel.
