Linux db2内存限制 [英] Linux db2 memory limit

问题描述

有没有人在Red Hat AS 2.1上有关于数据库共享内存限制的文件

？在AIX上，我知道它是2 GB减去为db2核心功能分配的段数b / b（大约是1.7），但我需要Linux的

数字（I '听说它只有1 GB）。如果有人知道这是正式记录在哪里，我也会非常喜欢它。

我可以指出我正在合作的一些团队。


谢谢，

Does anyone have documentation on the limit for database shared memory
on Red Hat AS 2.1? On AIX, I know it''s 2 GB minus the segments
allocated for db2 core functionality (so about 1.7), but I need the
numbers for Linux (I''ve heard that it''s only 1 GB). I would also
really love it if anyone knows where this is officially documented so
I can point some of the teams I''m working with to it.

Thanks,

Ember

推荐答案

IIRC，它应该是3.75G。

Linux的内存限制取决于你的内核;它的版本以及它是如何编译的。默认内核的限制为1GB（这意味着此限制中包含的1GB不是
）。然后你可以配置一个4GB限制的内核

（不包括I / O设备等;因此大约3.7GB）。我想你也可以在更新的内核上使用

扩展内存类功能。

Memory limit on Linux depends on your kernel; both its version and how it is
compiled. Default kernel has limit on 1GB (and this means that 1GB is not
included on this limit). Then you can configure a kernel with 4GB limit
(excluding I/O devices etc; thus about 3.7GB). I guess you can also use
extended memory kind features on newer kernels.

DB2确实支持Linux上的64位可寻址性。


如果你有32位芯片，那么限制是大约2.2 GB与

SuSE SLES 8 Service Pack 2和DB2 v8.1 FixPak 2或更高版本。


Ember写道：

DB2 does support 64-bit addressability on Linux.

If you have 32-bit chips, the limit is about 2.2 GB with
SuSE SLES 8 service pack 2 and DB2 v8.1 FixPak 2 or later.
