Aix 32位内核/ 64位硬件上的64位实例 [英] 64-bit instance on Aix 32 bit kernel / 64 bit hardware
问题描述
在32位内核上使用64位DB2实例是否值得：
- 性能
- 配置（超过私有内存的256 Mb段，
缓冲池的1.75 Gb）
- 其他？
我见过不支持NIS，不支持下层（64到32位？）
....
我应该使用DB2 64位吗？技术说明似乎令人困惑：
http://www-1.ibm.com/support/docview...=utf-8&lang= en
它声明了一些限制
- 您只能在32位操作系统上安装64位DB2 UDB版本8
AIX，HP-UX和Solaris操作环境上的
。 ==>您将无法创建或运行64位实例
。您只能创建和运行32位
实例。 < ==真的吗？
db2setup（8.2 / Aix）要求创建32位或64位实例。它好像
似乎db2iupdt -w 64工作正常，实例正在运行，但它是值得吗？
值得吗？
谢谢你你的帮助，

Hi,
Is it worth to use 64-bit DB2 instances on a 32-bit kernel, in terms of:
- performance
- configuration (go beyond the 256 Mb segment for private mem, 1.75 Gb for
Bufferpools)
- other ?
I''ve seen NIS is not supported, downlevel (64 to 32 bit ?) is not supported
....
The "Should I be using DB2 64-bit?" tech note seems confusing:
http://www-1.ibm.com/support/docview...=utf-8&lang=en
It states some restrictions
- You can install 64-bit DB2 UDB Version 8 on 32-bit operating systems only
on AIX, HP-UX and Solaris Operating Environments. ==>You will not be able to
create or run 64-bit instances. You can only create and run 32-bit
instances. <== Really ?
The db2setup (8.2 / Aix) asked for 32-bit or 64-bit instance creation. It
seems db2iupdt -w 64 works fine, and the instance is functionning, but is it
worth ?
Thanks for your help,
Jean-Marc
推荐答案
Jean-Marc，
我相信技术人员试图说的是你可以在32位操作系统下安装
64位版本的DB2（即DB2二进制文件），但是
安装DB2二进制文件后，必须以
顺序创建DB2实例以操作DB2数据库。我相信它说你不能在32位操作系统下创建64位实例。如果您在尝试这样做时没有收到
错误，我猜您处于未知领域，
并且无法获得IBM的支持。我不确定
在32位操作系统下使用64位实例有什么好处，如果你能得到的话，甚至是
即使它得到支持也能发挥作用。

Jean-Marc,
I believe what the technote is trying to say is you can install the
64-bit version of DB2 (i.e. the DB2 binaries) under a 32-bit OS, but
once you install the DB2 binaries, you must create DB2 instances in
order to operate a DB2 database. I believe it is saying that you cannot
create 64-bit instances under a 32-bit OS. If you didn''t receive an
error in attempting to do so, I guess you are in uncharted territory,
and risk not being able to get support from IBM. I''m not sure that
there''s any advantage to using a 64-bit instance under a 32-bit OS, even
if you are able to get it to work and it even if it IS supported.

我的理解是AIX是一个特殊情况，因为它有效。
但是，我不认为它得到官方支持。我不确定这个
是否明确不受支持，或者只是隐含地不支持
这个组合没有记录支持的事实。
My understanding is that AIX is a special case in that it works.
However, I don''t think it''s officially supported. I''m not sure if this
is explicitly unsupported, or simply implicitly unsupported by the fact
that the combination is not documented to be supported.
