Subject: Default shared memory SGML mention
Date: Wed, 2 May 2001 12:17:33 -0400 (EDT)
Message-ID: <200105021617.f42GHX811076@candle.pha.pa.us> (raw)
I am looking over the shared memory SGML files, and found that on my
BSD/OS system, I get as the following default shared memory size:
m 131072 5432001 --rw------- postgres user postgres
user 1 1236992 10622 10622 12:11:14 12:11:15 12:11:14
^^^^^^^
I have highlighted the size. If I subtract the default shared memory
buffers, I get:
1236992 - 8192 * 64
712704
so by my computations, we need about 700k added to the shared buffer
cache area. The documentation says to add 512k, not 700k. My guess is
that the non-cached shared memory area has increased in a recent
release, and docs were not updated. I will bump up the SGML mention to
700k unless someone shows a lower default shared memory size.
