Hi,
I've 1gb RAM and 2GB Swap on my Lclass server having Oracle Database of 50GB. What should be the value of maxdsize, maxssize and maxtsize.

How to set the integer value of these par using SAM.

How to convert 0x040000 to decimal value
and vice versa.

Thanks in advance.

This thread, contains a good copy of my kernel output with all settings that you require, from a L2000 box, 2 gb ram, 4 gb swap.

kmtune contains options in the man page for changing hex to numeric and back.

As does sam.

Hi Ashwin,

Kernel Values given below should be ok.
maxdsiz 0x40000000
maxdsiz_64bit 0x80000000
maxssiz 0x8000000
maxssiz_64bit 0x40000000
maxtsiz 0x4000000
maxtsiz_64bit 0x40000000

Conversion of decimal value to hexadecimal can been seen check through SAM --> Kernel Configuration --Configurable Parameters. It shows both the values.

Hi,
1)
maxdsiz 990056448
maxdsiz_64bit 4294967296

maxssiz 8388608
maxssiz_64bit 33554432

maxtsiz 67108864
maxtsiz_64bit 1073741824
2)
Just replace the integer values.
3)
For Conversion :
Very simple use you calculator of any windows O.S. and select view as scientific.
Here you can convert hex-dec and vice-versa.

The values can be just as recommended in the Oracle installation Guide.

In need you can bump this value to a higher value.

These parameters just describe the upper limit for the process so that it does not take away more resources.

you can just use

#echo "0x040000=D"|adb

to get the decimal value.
