INSTALLED RESOURCE LIST

 

The following resources are installed on the machine.

+/- = Added or deleted from Resource List.

*   = Diagnostic support not available.

 

       

 

 

 

解决方法：

 

如何和产品不符，咨询厂家实际情况并修复问题（更换内存？CPU？）

 

 

 

 

 

八、操作系统查看8

 

 

查看是否属于夏时制（不要是夏时制）[确认tz那行对应的不是TZ=1而是TZ=BEIST-8]

 

 

方法：”more /etc/environment”

 

 

类似结果:

 

 

# more /etc/environment

 

 

# @(#)18      

 

 

 1.25  src/bos/etc/environment/environment, cmdsh, bos53A, a2004_

解决方法:

 

 

||||||||||||||||||

若时区不是”BEIST-8”，则通过smitty chtz 改时区（改完时区之后需要重启才能生效）

 

 

Smitty chtz-> Use DAYLIGHT SAVINGS TIME?(选择no)-> CUT (Coordinated Universal Time) Time Zone  (选择”(BEIST-8)   Peoples Rep. China        (CUT +8)”)       

 

|||||||||||||||||||

 

 

九、操作系统查看9

检查rac两节点是否时间同步，用“date ”命令查看（首先确认时区要一致）

结论，若不同步， 通过smitty date改 时间

 

 

 

 

 

 

 

十、数据库查询1

 

 

数据库版本检查，是否为最新:  检查数据库版本和crs的版本是否打到最新(10.2.0.5):

 

 

方法:

 

 

"sqlplus -version"， 查看software版本

 

 

 "crsctl query crs softwareversion"  查看crs版本

 

 

类似结果

$ sqlplus -version

SQL*Plus: Release 10.2.0.5.0 – Production

# crsctl query crs softwareversion

CRS software version on node [zzrac1] is [10.2.0.5.0]

 

 

解决方案：

如果补丁集较低，建议升级补丁:

1>、应用备份数据

 

 

2>、升级rac crs

 

 

3>、升级oracle software

4>、升级库版本

5>、编译无效的对象

||||||||||||||||

 

 

十一、数据库查询2

 

 

（数据文件如果采用裸设备的方式）检查是否数据库文件关闭了自动扩展（建议关闭自动扩展)（用toad上去观察)

 

 

方案: 使用toad检查问价系统状态

 

类似结果:

 

 

 

 

 

解决方案：

 

 

关闭相应的数据文件的自动扩展:

 ALTER DATABASE TEMPFILE '/dev/rrac_temp_2G' AUTOEXTEND OFF;

 

 

 

 

十二、数据库查询3

 

 

检查数据库文件是否已经和lv大小相近似(建议扩充文件系统，接近到可扩充的最大文件）

 

 

方法：使用toad检查

 

 

类似结果

 

 

 

 

解决方案：（rac_temp_2G对应了8个pp）

查看pp大小（1个pp大小为256M）

所以rac_temp_2G 可以扩展到2G（8*256M）

 

 

如果没有扩展到适应大小，用下面命令：（确认lv大小）

           ALTER DATABASE TEMPFILE '/dev/rrac_temp_2G' RESIZE 2000M;
