监听日志过大导致数据库连接变慢

6月 25,2014 有2条评论 Oracle, oracle 11g

收到公司一项目组邮件，说某开发环境的数据库连接不稳定，时快时慢，但是一旦连上数据库，整体的操作并不慢，想让我帮忙看看。

环境：Windows 2K8 R2 64位操作系统+Oracle 11gR2 64 bit单实例数据库。

现象：在数据库服务器上，tnsping本地机器上的Oracle网络服务名，果然时快时慢。快时延迟只有10毫秒或者是0毫秒，而慢时延迟能达到10000多毫秒。这个显然不能接受。

思路：

1 第1反映可能是Oracle网络配置问题；

2 数据库服务器或者监听进程过于繁忙导致的；

处理：

经过排查和分析，由于是开发环境，各种不知名的原因，导致该Windows服务器上安装了1套10g的数据库软件[未建库]，1套文中提到的11gR2单实例数据库，10g和11g版本的环境分别创建了各自的监听程序，10g的在默认1521端口，11g的在1522端口，并且2个监听程序的名字都是listener。问题更为蹊跷的是，如果tnsping 10g软件下的网络服务名很正常，tnsping 11g软件下的网络服务名才会出现时快时慢的现象。

于是乎，停掉10g环境下的那个占用1521端口的监听，重新配置11g的监听使之驻留在1521端口上。此时问题依旧：

C:\Users\Administrator>tnsping orcl

OK (0 毫秒)

OK (7360 毫秒)

说明问题应该不至于出现在网络配置上面。

同时，该库是一个开发用的数据库，更谈不上繁忙之说。

那么，问题究竟应该出现在那儿呢？既然，在服务器上tnsping本地机器上的网络服务名不稳定，且SQL*PLUS通过网络服务名来访问本地机器上的Oracle服务肯定也会慢，那么就发起一个本地的网络服务连接，然后看看监听的日志信息。果不其然，发现了一点儿端倪，监听程序的日志文件过大：

listener_log_4GB

原来，造成问题的罪魁就是这个过大的日志文件[Windows下Oracle的监听日志文件超过4G大小，便会出现该问题]！解决的方法就很简单，停止监听程序，删除监听日志文件，重启监听，问题解决！

谨慎细致的德国客户同事

5月 28,2014 有1条评论 Life, Oracle

这次，在德国出差期间，不巧的是，干活儿的家伙什蓝屏罢工了。向德国客户求助，德国人原本想帮我重新安装个正版的Windows系统，但想想，不对劲，友好的说，到时候你还是要把这个正版的软件带回China。

所以，作罢。

然后，德国佬给我提供了一台式机，并帮我做了些基本配置。开机，进入桌面之后，瞬间就觉得人家德国人做事的贴心与细致了：

原来，这哥们儿深知我干的是数据库相关的活儿，所以就事先在桌面上帮我创建好了访问数据库服务器远程桌面的快捷方式。

瞬间，觉得温暖。

Windows 10gR2 RAC迁移OCR和Vote Disk以及ASM磁盘组上的数据

5月 9,2014 有1条评论 Oracle, RAC

概要：本文详细记录如何把运行在Windows 2K8环境上的Oracle 10gR2 双节点RAC数据库的OCR、Vote Disk以及存放在ASM磁盘组里的数据，迁移至新存储的步骤。

迁移之前的存储信息：

如上图所示，我们的最终目标是要把OCR、Vote Disk，DATA、FLASH磁盘组从Disk 2，Disk 3上分别迁移至Disk 4和Disk 5。

接下来给出详细的操作步骤和流程：

1 迁移OCR

A 创建磁盘分区

C:\Users\Administrator>diskpart

Microsoft DiskPart version 6.1.7601

* Partition 2    Logical           5825 MB   323 MB

DISKPART>

分区之后：

注：您应该在其他节点上看到同样的磁盘分区信息。且，建议在其他节点上将Windows系统自动给新分区分配的盘符移除掉。

B 准备磁盘，创建裸设备链接

C:\oracle\product\10.2.0\crs\BIN\GUIOracleOBJManager.exe

同样，执行完上述操作，您应该在RAC的所有节点上通过

C:\oracle\product\10.2.0\crs\BIN\GUIOracleOBJManager.exe程序看到相同的信息。

C 手工备份OCR

ocrconfig -export c:\oracle…..\backup_filename

备份之前，可以查看下OCR的自动备份信息：

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -showbackup

hamnode2     2014/05/08 06:01:07     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode2     2014/05/07 19:44:04     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode2     2014/05/06 16:34:35     C:\oracle\product\10.2.0\crs\cdata\crs

hamnode1     2014/04/30 07:09:51     C:\oracle\product\10.2.0\crs\cdata\crs

c:\oracle\product\10.2.0\crs\BIN>

执行备份：

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -export C:\oracle\product\10.2.0\crs\cdata\crs\backup_ocr_140508.bak

c:\oracle\product\10.2.0\crs\BIN>cd ..\cdata\crs

c:\oracle\product\10.2.0\crs\cdata\crs>

D 添加OCR镜像

ocrconfig -replace ocrmirror \\.\ocrmirror

添加之前，查看OCR信息：

c:\oracle\product\10.2.0\crs\BIN>ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     327452

Device/File Name         : \\.\ocrcfg

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

c:\oracle\product\10.2.0\crs\BIN>

添加OCRMIRROR并验证：

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -replace ocrmirror \\.\ocrmirror

c:\oracle\product\10.2.0\crs\BIN>ocrcheck

Status of Oracle Cluster Registry is as follows :

Device/File integrity check succeeded

Device/File Name         : \\.\ocrmirror

Device/File integrity check succeeded

Cluster registry integrity check succeeded

c:\oracle\product\10.2.0\crs\BIN>

E 删除OCR device并验证

c:\oracle\product\10.2.0\crs\BIN>ocrconfig -replace ocr

c:\oracle\product\10.2.0\crs\BIN>ocrcheck

Status of Oracle Cluster Registry is as follows :

Version                  :          2

Total space (kbytes)     :     327452

Used space (kbytes)      :       3836

Available space (kbytes) :     323616

ID                       :  478679697

Device/File Name         : \\.\ocrmirror

Device/File integrity check succeeded

Device/File not configured

Cluster registry integrity check succeeded

c:\oracle\product\10.2.0\crs\BIN>

F 重启CRS并验证

至此，我们通过给OCR添加1份镜像然后删除原主OCR的方式，完成对OCR的迁移。

注：通过这种方式，删除原OCR之后，新添加的OCR镜像自动成为主OCR。

2 迁移Vote Disk

A 创建磁盘分区

这里的创建磁盘分区如创建OCR磁盘分区时，方法一致：

5 删除磁盘分区

删除卷、磁盘分区信息之后：

最终，对于OCR、Vote Disk的数据，我们分别通过添加镜像的方式，然后删除现有的配置，进而间接的将OCR、Vote Disk分别从Disk 2、Disk 3迁移到Disk 4和Disk 5。

对于存放在ASM 磁盘的DATA和FRA中的数据，我们是通过先对现有DATA、FRA 磁盘组分别添加ASM磁盘，然后删除磁盘组中原有的旧ASM磁盘，进而完成迁移ASM 磁盘数据的目标！

6 注意事项

1 Note:

Note:

You can migrate the RAC OCR when CRS is running ,but you cannot migrate the Voting Disk when the CRS is running.That means we must stop the CRS before we can migrate the Voting Disk.

2 Note:

Also,you must backup the voting disk when the CRS is running,or else if you shutdown the CRS first,and then you cannot use the ocopy command to backup the voting disk.

3 Note:

PROT-22: Storage too small

Cause:

The ocrmirror disk space is less than the ocr disk space.

Solution:

Enlarge the ocrmirror disk space as the same as the ocr disk space.

4 Note:

PROT-21: Invalid parameter

Cause:

PROT-21 error is encountered because the cluster is not yet fully aware of the newly created logical drive that is being specified for <filename> in the ocrconfig -replace command.

Solution:[Doc ID 1059663.1]

This code defect is fixed in patch bundle 31 (and higher) for Oracle on Windows.
Patch 31 is available for download from My Oracle Support under the following patch numbers:

Microsoft Windows (32-bit) – 9233830
Microsoft Windows Itanium (64-bit) – 9233831
Microsoft Windows x64 (64-bit) – 9233832

There is also a relatively simple workaround available. Namely, stop and restart the Oracle Object Service after creating the symbolic link for the new logical drive and before running the ‘ocrconfig -replace’ command.

Windows下如何查看ASM磁盘对应的设备？

4月 8,2014 有2条评论 ASM, Oracle

如题，在Windows系统下维护ASM磁盘提供存储设备的Oracle数据库时，该如何确定ASM磁盘对应的磁盘设备呢？

1 在操作系统层面看到下述磁盘信息，Disk 0是操作系统盘，Disk 1,Disk 2是2块ASM磁盘：

wps_clip_image-11545

2 从ASM实例里，看到磁盘组、磁盘的信息如下：

SQL> select name,total_mb,free_mb,state from v$asm_diskgroup;

NAME                             TOTAL_MB    FREE_MB STATE
------------------------------ ---------- ---------- -----------
ORADATA                            206849      32661 MOUNTED

SQL> select name,total_mb,free_mb,state from v$asm_disk;

NAME                             TOTAL_MB    FREE_MB STATE
------------------------------ ---------- ---------- --------
                                   206849          0 NORMAL
ORADATA_0001                       206849      32661 NORMAL

SQL> select name,total_mb,free_mb,state,path from v$asm_disk;

NAME                             TOTAL_MB    FREE_MB STATE    PATH
------------------------------ ---------- ---------- -------- --------------------
                                   206849          0 NORMAL   \\.\ORCLDISKORADATA0
ORADATA_0001                       206849      32661 NORMAL   \\.\ORCLDISKDATA0

SQL>

上述看到的信息已经是对ORADATA磁盘组执行过drop disk之后看到的信息。

那么接下来，如果想要OS级别移除ORADATA磁盘里path为\\.\ORCLDISKORADATA0的磁盘的话，该如何确定该磁盘对应OS级别的磁盘呢？究竟是Disk 1还是Disk2呢？

3 方法1：

C:\Users\Administrator>asmtool -list
NTFS                             \Device\Harddisk0\Partition1           278973M
ORCLDISKDATA0                    \Device\Harddisk1\Partition1           206849M
ORCLDISKORADATA0                 \Device\Harddisk2\Partition1           206849M

C:\Users\Administrator>

方法2：

通过DBCA进入ASM管理[Oracle 10g版本，11g应该使用ASMCA]之后，选择给磁盘stamp disk之后，也可以看到下述信息：

wps_clip_image-11662

进而，均可以可定path为\\.\ORCLDISKORADATA0的ASM磁盘对应于OS上的Disk2。

4 通过上述第3步骤移除磁盘的stamp操作之后，看到的信息如下：

wps_clip_image-11786

此时，已经从ASM实例里看不到ASM磁盘的信息了。

5 最终，从OS级别删除磁盘Disk 2的卷信息，分区信息之后，如下：

wps_clip_image-11848

附：在Linux上，可以直接通过/usr/sbin/oracleasm querydisk /dev/sd*的方法来查找ASM磁盘对应OS级别的设备信息。

11gR2 OCP实验1：搭建数据库服务器OEL5.5 X86_64

3月 20,2014 有4条评论 OCP, oracle 11g

一实验目的

本实验是整个系列教程的前期准备，即部署Oracle数据库服务器。这里通过虚拟机技术来创建一台Linux服务器，后续的章节中我们将在该数据库服务器上安装Oracle 11gR2数据库软件，并创建数据库。

Note：

1 操作系统选择Oracle公司的Oracle Enterprise Linux5.5 X86_64，非必须，也可以选择其它版本Linux，如Redhat，建议选择64位系统，但不建议选择Windows平台。

2 虚拟机平台选择VMware公司的VMware ESXi Version 5.1的虚拟主机，条件不允许的话，也可以选择安装VMware Server作为虚拟机软件。

二软件获取

软件名称	官方下载	百度网盘	360网盘
OEL 5.5 X86_64	https://edelivery.oracle.com /linux	http://pan.baidu.com /s/1jGwpx1k	http://yunpan.cn /QIV29JTXNGrP4
VMware Server	http://www.vmware.com/ download/server/	http://pan.baidu.com /s/1jGwpx1k	http://yunpan.cn /QIV29JTXNGrP4

三实验步骤

这里，我们需要完成在VMware ESXi Version 4.0的虚拟主机上创建1台虚拟机的工作，其中虚拟机的基本配置信息如下表[这里仅给出建议值，非必须，具体视实际硬件资源而定]：

Item	Value	Mark
OS	OEL 5.5 X86_64
Kernel	2.6.18-194.el5 X86_64
Hostname	OCP11gR2
Domain	oracleonlinux.cn
IP	172.16.0.224/20	掩码为255.255.240.0
Gateway	172.16.15.254
Hard disk 1	30G
Hard disk 2	8G	后续配置ASM磁盘用
Hard disk 3	8G	后续配置ASM磁盘用
CPU	4c
Memory	2G
Swap	4G

表1 虚拟机基础配置信息表

1 配置虚拟机，安装OEL 5.5 X86_64位Linux操作系统

以root用户登录172.16.0.181的虚拟主机：

进入虚拟主机管理界面：

新建虚拟机,选择Custom，Next进入下一步：

给虚拟机命名为11gR2–OCP，Next：

选择Datastore位置，这里选择第1个名为snap-62ed4023-BAT的存储设备，Next：

虚拟机版本选择version 8，Next：

操作系统类型选择Linux，版本选择Red Hat Enterprise Linux 5(64-bit)，Next：

CPU核数选择4，Next：

内存选择2G，Next：

网卡选择1块，Next：

SCSI驱动器类型选择LSI Logic Parallel，Next：

选择创建新磁盘，Next：

磁盘大小选择30G，Next：

虚拟设备节点选择默认SCSI(0:0)，Next：

选中在虚拟机创建之前编辑选项，Continue：

编辑光驱设备，选择ISO文件，找到之前已经准备就绪的OEL 5.5 X86_64位的ISO文件：

选中光驱在启动时连接选项，最后，单击Finish完成。

至此，一台新的虚拟机配置完成。

2 启动11gR2–OCP虚拟机，安装Linux操作系统

给11gR2–OCP虚拟机加电，进入图形界面开始安装系统：

回车，进入安装：

Skip，跳过光驱检查：

Next，开始安装Oracle Enterprise Linux：

语言选择—>English，键盘选择–>U.S.English美式键盘，硬盘分区选择最后一个选项Create custom layout，Next：

给硬盘分区，其中SWAP分区选择4000M，剩余空间全部划给根分区/，Next：

网络配置，参照表1 虚拟机基础配置信息表，分别配置eth0网卡的IP、子网掩码、网关、主机名，Next：

时区选择，亚洲/上海，Next，配置root用户口令，Next：

选择定制软软包，Next：

Note：
    Desktop Environments:
               GNOME Desktop Environment
    Applications:
               Editors
    Development:
               Development Libraries
               Development Tools
               GNOME Software Development
               Legacy Software Development
               X software Development
    Base System :
               Administration Tools
               Base
               Legacy Software Support
               System Tools
               X Window System

其它的软件包，可以忽略，暂时不装，一来加快操作系统的安装进度，二来其余的软件包对于配置Oracle 11gR2 数据库环境而言不需要，如果在将来的安装过程中，系统提示缺失软件包的时候，我们也可以手工从安装光盘中自行安装。Next：

进入格式化文件系统，开始安装软件包，直到最后：

根据提示，选择reboot系统。

系统重启之后，Forward，选择关闭Firewall，Next：

禁用SELinux，Next：

直到最后一步，按照提示，再次重新启动系统，使刚才的配置生效。

重启之后，键入root用户名和对应的口令，登录进入图形界面：

到此，通过虚拟机技术已经成功创建1台OEL 5.5 X86_64位系统的数据库服务器。

四实验结果

通过完成本实验，您应该掌握通过虚拟机技术来创建1台Linux虚拟机，以便为后续的实验课程做好铺垫！

一步一步在Linux上升级10gR2 RAC到11gR2 RAC(6)

1月 22,2014 留下评论 Oracle, RAC

11 升级10gR2 RAC数据库至11gR2 RAC数据库

升级前的准备工作：

A 确保原10g RAC数据库在双节点上都已经正常关闭，如果没关闭，请确保在所有节点上都关闭。

B Copy 10gR2 RAC下的初始化参数文件、口令文件、网络配置文件至11gR2 软件下对应的目录

节点1：

node1-> cp /u01/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora /u01/app/oracle/product/11.2.0/db_1/network/admin/

node2-> cp /u01/app/oracle/product/10.2.0/db_1/dbs/orapwdevdb2 /u01/app/oracle/product/11.2.0/db_1/dbs/

node2->

Note 1：

请将cluster_database=false，如果不修改该参数的话，在下一步中，用11gR2版本的数据库软件来拉起10gRAC库的时候，您会遭遇下述错误：

即，在启动数据库的过程中，发现Hang：

果不其然，发现报错！！！

D 执行预检查脚本

根据上一步的错误提示：

我们要以原来10gRAC环境的数据库软件来启动数据库，去执行1个升级前的预检查脚本：

Note：

该预检查脚本是要把低版本的数据库升级到11204版本的数据库需要执行预检查的脚本，可以参考MetaLink官方文档：Doc ID 837570.1及Note 884522.1

这里将utlu112i_7.sql脚本下载至/home/oracle路径下。

这里要以原来10gRAC环境的数据库软件来启动数据库、并且以UPGRADE方式来启库、且需要注意环境变量需要设置成对应原10g RAC数据库软件的配置。

同样，记得需要修改10g参数文件里的cluster_database=false。

Note：

11gR2版本下，oracle会自动创建一个隐含参数”__oracle_base”，而在10g版本下不支持该参数。当然，如果不去掉该参数的话，那么您可能会遇到下述错误：

node1-> export ORACLE_SID=devdb1

node1-> export ORACLE_BASE=/u01/app/oracle

node1-> export ORACLE_HOME=/u01/app/oracle/product/10.2.0/db_1

Oracle用户调用/u01/app/11.2.0/grid/bin/asmca 进入ASMCA图形界面来将之前10gR2 RAC下的2块ASM磁盘添加到11gR2 grid软件下来进行管理。

Q ：为什么可以把存放10g数据库的磁盘放在11g ASM实例来管理？

A ：可以参考本人之前文章如何在一台服务器上共用一个ASM实例来创建10.2.0.5和11gR2的物理备库

收到公司一项目组邮件，说某开发环境的数据库连接不稳定，时快时慢，但是一旦连上数据库，整体的操作并不慢，想让我帮忙看看。

环境：Windows 2K8 R2 64位操作系统+Oracle 11gR2 64 bit单实例数据库 。

现象：在数据库服务器上，tnsping本地机器上的Oracle网络服务名，果然时快时慢。快时延迟只有10毫秒或者是0毫秒，而慢时延迟能达到10000多毫秒。这个显然不能接受。

1 第1反映可能是Oracle网络配置问题；

2 数据库服务器或者监听进程过于繁忙导致的；

概要：本文详细记录如何把运行在Windows 2K8环境上的Oracle 10gR2 双节点RAC数据库的OCR、Vote Disk以及存放在ASM磁盘组里的数据，迁移至新存储的步骤。

1 迁移OCR

A 创建磁盘分区

B 准备磁盘，创建裸设备链接

C 手工备份OCR

D 添加OCR镜像

E 删除OCR device并验证

F 重启CRS并验证

2 迁移Vote Disk

A 创建磁盘分区

B 准备磁盘，创建裸设备链接

C 查看Vote Disk信息

D 备份Vote Disk

E 停止CRS

F 添加Vote Disk

G 删除原Vote Disk

H 启动CRS并验证

3 迁移ASM DATA磁盘组

A 查看ASM磁盘信息

B DATA磁盘组添加磁盘
