Re: Total memory calculation

Why do you need the exact size of the dataserver executable. This size will change which every new version of the binaries that you would use.

The best way to check the size of the memory requirements for ASE is to set up the 'max memory' variable. This setting will set the upper limit for the memory allocation in ASE.

The easiest way to check what is the current memory usage by running

sp_configure 'total logical memory'

More details are here:

How much memory to configure

All the other parameters are also set by sp_configure.

When you add some memory to some functionality, the remaining memory from (max memory - total logical memory) will decrease.

correct

>Devices x 45,056 bytes +                   ----number of devices???

correct

incorrect

The procedure cache is set up by 2k page size

sp_configure 'procedure cache size'

This is the sum of all your data cache:

sp_cacheconfig will give you a summary
