#Caché

Below are the output messages when Cache start.

Allocated 178MB shared memory: 1MB global buffers, 26MB routine buffers

I try to configure the global buffer size by [System] -> [Configuration] -> [Memory and Startup] from SMP,

but it seems like the changes does not apply to the global buffer.

Thanks for your help.

Make sure you don't assign more memory than the available physical memory : your OS will swap to the hard disk which will cancel the benenefits of global buffers.

You need to restart Caché after making and saving the changes.

I did, but it still remain the same.

Is this field of SMP corresponding to the global buffer [Memory Allocated for 8KB Database Cache (MB)] ?

I would like to 10G memory to global buffer, is there any constraint about the upper limit ?
