Hi, I have a question with shared_buffer.
Ok, I have a server with 4GB of RAM
- -----
# cat /proc/meminfo
MemTotal: 4086484 kB
[...]
- -----
So, if I want to, for example, shared_buffer to take 3 GB of RAM then
shared_buffer would be 393216 (3 * 1024 * 1024 / 8)
Postmaster dont start.
Error: FATAL: shmat(id=360448) failed: Invalid argument
I can set a less value, but not higher than 3 GB.
Am I doing something wrong?
Any idea?
