OS X上的共享内存 - 7.4beta4 [英] shared memory on OS X - 7.4beta4

问题描述

当我尝试在OS X上启动一个新编译的beta4时，我得到了这个结果

10.2.6：


致命：无法创建共享内存segment：无效的参数


我在beta2上看到了一个关于此的前一个帖子。这听起来像是一个在beta3中修复的

错误，但我仍然遇到这个问题

与beta4。

谢谢，

编译并启动正常在我的OSX 10.2.8机器上


干杯

您请求多少SHM（shared_buffers），系统是否允许这么多？如果需要，可以在OSX中修改一些启动脚本

以达到该限制。检查谷歌和/或Postgres的'techdocs

网站。

我做了一个默认配置，并没有更改.conf中的任何内容

文件。它请求10444800字节。但即使我将max_connections

降至10，它仍然不会开始。是的，我可以为

操作系统修改SHMMAX以使其正常工作但我正在努力理解为什么我需要在没有必要的情况下执行此操作7.3或更早的7.4

开发版本（pre beta 1）。我本来希望它是一个bug，因为我认为如果我不得不担心很多低级操作系统设置只是为了设置一个，那么它会对Postgresql的采用造成伤害。简单的数据库。


最好，

I get this when I try to start up a freshly compiled beta4 on OS X
10.2.6:

FATAL: could not create shared memory segment: Invalid argument

I saw a previous thread on this for beta2. It sounded like this was a
bug that was to be fixed in beta3, but I''m still having this problem
with beta4.

Thanks,

I don''t know what this error is particularly, but just to say that 7.4beta5
compiles and starts up fine on my OSX 10.2.8 machine

Cheers

How much SHM are you requesting (shared_buffers), and does the system
allow for that much? There''s some bootup script you can modify in OSX
to up that limit if you need. Check google and/or Postgres'' techdocs
site.

I did a default configure and did not change anything in the .conf
file. It requests 10444800 bytes. But even if I drop max_connections
down to 10, it still won''t start. Yes, I can modify SHMMAX for the
operating system to make it work but I''m trying to understand why I
need to do this when it was not necessary under 7.3 or an earlier 7.4
development build (pre beta 1). I was hoping it is a bug, because I
think it hurts the adoption of Postgresql if I have to worry about a
lot of low level OS settings just to setup a simple database.

Best,
