AIX高手挑战赛，这道题难倒你了吗？

3月 14,2012 有2条评论 Oracle, RAC

记得，之前在某论坛在线参加了一次AIX高手挑战赛，成绩不太理想，顺手把其中的某道题以txt文本方式记录下来了，刚才整理机器的时候，看到该题目，就整理在这儿了，那么这道题目也难倒你了吗？

Oracle10g或者11g的Real Application Cluster(RAC)版本，在AIX操作系统上是使用User Datagram Protocol(UDP)协议作为interprocess通讯的。为了提高Oracle的性能，需要调整UDP参数的设置。需要使用no命令来修改udp_sendspace和udp_recvspace参数。如：将udp_sendspace参数设置成为:[(DB_BLOCK_SIZE*DB_FILE_MULTIBLOCK_READ_COUNT)+4096]，并且不小于65536; 将udp_recvspace参数设置为>=4*udp_sendspace; 如果需要，增加sb_max参数（缺省是1048576），因为sb_max必须>=udp_recvspace. 为了确定udp_recvspace是否设置的合适，可以使用如下哪条命令：

A netstat -s | grep "socket buffer overflows"

B lsattr -El udp_recvspace

C no -a | grep udp_recvspace

D 以上都不是

答案应该选哪个呢？各位网友，可以回复给出你的答案…..

解决11gR2 RAC 客户端ORA-12545错误一则

3月 13,2012 有1条评论 Oracle, RAC

在一套Linux环境下X86_64的11gR2 RAC数据库集群中，客户端通过SCAN IP访问数据库时遇到下述错误：

通过查找MetaLink：ORA-12545 or ORA-12537 While Connecting to RAC through SCAN name [ID 970619.1]得到解决方法，修改数据库的local_listener参数：

至此，问题解决。

产生问题原因：

Client is able to resolve all Fully Qualified Domain Name (FQDN) SCAN and VIP name but not short ones(without domain name) as its in different domain; even though FQDN names were specified during Grid Infrastructure setup, due to bug 9150053 by default DBCA set database parameter local_listener to short node VIP name while database is created.

解决方法除了上述之外，我们也可以按照下面的方法解决，其实，都是换汤不换药，个人倾向于直接在监听里配置IP地址：

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=rac1-vip.localdomain)(PORT=1521))))' sid='devdb1';

System altered.

SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=rac2-vip.localdomain)(PORT=1521))))' sid='devdb2';

System altered.

SQL> alter system register;

System altered.

Oracle 10g RAC 配置物理dataguard系列3：物理备库配置步骤

2月 17,2012 有6条评论 Dataguard, Oracle, RAC

在上一篇文章Oracle 10g RAC 配置物理dataguard系列2：备库安装、升级oracle软件、配置ASM实例中，我们已经在物理备库上顺利安装、升级oracle软件同RAC主库版本一致的10.2.0.5，并且配置好ASM实例，这些准备工作一切就绪之后。接下来，我们需要在物理备库机器上一步一步的配置physical dataguard。

1 主库执行RMAN备份的准备工作：

其实，在配置physical standby dataguard时，主库必须要置于归档模式，且建议将数据库也置于FORCE LOGGING模式。在这里，我们在系列一文章里查看主库基本信息中，已经看到这些已经准备就绪。否则，需要将主库置于归档+FORCE LOGGING模式，在这里就省略这一步骤，当然我们也可以通过下述得以确认。在主库的第一个节点上执行：

我们分别修改了两个节点的归档路径，节点1的归档指向/home/oracle/arch1，节点2的归档指向/home/oracle/arch2,这两个路径事先已经建好，这一步骤必须完成！

由于我们的RAC主库归档路径都各自指向本地存储，并没有放到共享存储上，所以，这里我们在用RMAN做备份的时候，需要连接到每个实例上进行备份。我们备份的路径分别指向每台机器的/oracle_backup，且在每个节点上也事先建好/oracle_backup路径，且确保oracle用户有对该路径的路写权限！

接下来，在节点1上执行备份，注意下述的rman备份命令中的GLNDB2连接字符串是连接到节点2的实例上，已经在节点1的/u01/app/oracle/product/10.2.0/db_1/network/admin/tnsnames.ora事先配置好。

      (SERVER = DEDICATED)
      (SERVICE_NAME = glndb)
      (INSTANCE_NAME = glndb2)
    )
  )

GLNDB1 =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.0.35)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = glndb)
      (INSTANCE_NAME = glndb1)
    )
  )

GLNDB =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.0.35)(PORT = 1521))

到各个节点的/oracle_backup路径下确认备份文件信息：

节点1：

6 在备库上使用orapwd命令创建口令文件，要确保sys用户或者具有sysdba系统权限用户的口令要同主库两个节点上sys用户的口令一致。为简单起见，也可以在主库两个节点上分别修改sys用户口令为一致，然后，直接拷贝主库任意节点的口令文件到备库$ORACLE_HOME/dbs路径下，并且重命名为orapwSID，其中SID为备库上实例名，这里备库SID为pridb,，所以口令文件名应该为orapwpridb。

这里，在RAC两个节点上分别修改sys用户口令，然后，cp节点1下的口令文件到物理备库172.16.0.202的$ORACLE_HOME/dbs路径下，然后在备库上重命名该文件：

然后，在确认物理备库控制文件恢复成功后，将物理备库置于MOUNT状态，接下来restore物理备库：

其次，SQL*PLUS连接物理备库，确认状态：

从上述的错误信息，可以看到备库整等待主库第一个节点上的日志号为7707的日志。其它的错误信息提示是指备库第一次置于recover状态时，备库将生成对应的online redo log，这是正常的，可不必理会。

14 调整主库参数，使主库上的归档日志可以顺利传递到备库上去，其中也包括在主库备份完成到备库置于recover状态之间主库产生的归档日志，及archive log gap。

可以看到，主库节点1已经产生7711归档的本地日志，而备库上却没有接收到任何归档日志：

[oracle@ora10grac-dg arch2]$ pwd
/home/oracle/arch2
[oracle@ora10grac-dg arch2]$ ll
total 0
[oracle@ora10grac-dg arch2]$

并且物理备库的告警日志暂时也没有任何提示信息！！在这一步，尝试了N久，才发现备库的监听没有启动，导致主库无法连接物理备库，自然，主库的归档也就无法传递到物理备库。具体，可见下面的记录信息，首先在节点1上，在SQL*PLUS里尝试用pridb网络服务名连接物理备库时报错，没有监听，然后到物理备库启动监听，在物理备库上重新执行应用归档，最后问题的以解决！

主库尝试连接备库报错：

SQL> conn sys/oracle@pridb as sysdba
ERROR:
ORA-12541: TNS:no listener


Warning: You are no longer connected to ORACLE.
SQL>

备库监听未启，然后启动：

看到这些信息后，才说明主库所有节点的归档日志已经全部传递到物理备库，且物理备库也成功应用了这些归档！

15 主库创建standby logfile。在主库上创建standby logfile的目的和作用是，将来在做switchover时，RAC主库变成新standby备库，而原来的物理备库变成新主库时，新standby备库可以顺利接受并应用新主库的归档日志。当然，也别忘记了要修改主库的standby_file_management、db_file_name_convert、log_file_name_convert这三个重要的参数！

发现，最后两个参数不能修改！百思不得其解，不得已，只好通过创建PFILE，在PFILE里修改这两个参数，然后再利用该PFILE来创建SPFILE的方式来修改之！

终于，终于，经过漫长的配置，我们的dataguard成功创建！关于dataguard的功能测试，将在下一篇文章里介绍！依然敬请期待！

Oracle 10g RAC 配置物理dataguard系列1：RAC主库信息概览、备库准备工作

2月 14,2012 有1条评论 Dataguard, Experience, Oracle, RAC

最近在学习Oracle dataguard相关知识。本系列就Oracle Enterprise Linux 5.5 X86_64位环境下Oracle 10g 10.2.0.5.0双节点RAC数据库配置一套物理dataguard做一记录，一来给自己的学习做一简单记录，二来，同样希望可以给广大网友及Oracle数据库技术爱好者提供思路。

在实施之前，简单介绍下背景、最终目标及配置步骤：

背景介绍：主库是一套运行在Oracle Enterprise Linux 5.5 X86_64位环境下Oracle 10g 10.2.0.5.0双节点RAC数据库，主库用的是ASM存储，ASM磁盘利用raw来实现；
最终目标：需要给该主库搭建一套同样是运行在Oracle Enterprise Linux 5.5 X86_64位环境下的物理备库，并且能够switchover，确保高可用
配置步骤： 1 了解现有主库的配置信息；

2 搭建一台干净的新机器，用于创建物理备库使用；

3 在物理备机上安装oracle数据库软件，并且升级到同主库软件版本一致，即10.2.0.5.0；

4 在物理备机上创建ASM实例，ASM磁盘同样选择裸设备来实现；

5 配置物理备库；

6 确认switchover成功，双节点RAC+physical standby既可提供实例级别容灾(RAC功能)又可以提供存储级别容灾(Dataguard功能)，做到真正的高可用！

本篇是整个实施过程的系列1：本篇的内容主要是查看主库基本配置信息，及创建一台干净的Linux服务器，用作备库。

一首先了解下现有双节点RAC数据库配置信息：

二在获取了RAC主库的基本信息之后，接下来搭建一套新的机器做物理dataguard用

本文采用的是在一套虚拟机上搭建另外的备库机器，该虚拟机软件是VMware ESX 4.0，该软件其实可以认为是一个操作系统，是直接装在物理机器上的，有别于Vmware公司的VMware Server、VMware Workstation软件，后两者是先需要有操作系统，然后在操作系统上安装该虚拟机软件。而且，VMware ESX 4.0虚拟机软件相对来说也要比后两者稳定。

用Vmware vSphere Client工具登录虚拟机控制台：

登录控制台后，虚拟机信息概览：

2 选择File–New–Virtual Machine，新建虚拟机命名为10gRAC-Dataguard：

3 接下来一步一步走，同在VMware Server、VMware Workstation里创建新虚拟机一样，在此不再赘述。配置后的虚拟机概览如下：

4 给10gRAC-Dataguard加电，开始安装操作系统，虚拟机磁盘分区如下：

5 虚拟机网络配置信息如下：

IPv4:172.16.0.202

Netmask:255.255.240.0

Gateway:172.16.15.254

DNS:Null

Hostname:ora10grac-dg

6 软件包安装时，选择客户化，其中，下述是选择要安装的软件包：

Desktop Environments：GNOME Desktop Environment

Applications:

Editors

Graphics

Development:

Development Libraries

Development Tools

GNOME Software Development

Legacy Software Development

X software Development

Base System:

Administration Tools

Base

Legacy Software Support

System Tools （其中，选择oracleasm软件包。注：默认情况下并没有oracleasmlib-2.0.4-1.el5软件包，如果采用asmlib来管理和创建asm磁盘的话，仍需要后续手工安装该RPM包，否则将来配置ASM存储时会找不到ASM磁盘！！！）

暂时，先安装这些软件包，稍后在安装oracle软件时，如有缺失软件包的话，再续安装，至于其它的Server，虚拟化，集群软件包一概不装！

7 接下来，进行格式化文件系统，进入系统安装。稍后，还有一些后续的配置工作，记得不要开启SELinux并且关闭防火墙！最后，一台新的虚拟机配置成功，登录界面如下：

8 新虚拟机基本信息如下：

这样，一台新的物理备库机器配置成功！接下来需要在该机器上安装oracle软件，配置ASM，升级oracle软件到10.2.0.5.0版本，下篇继续！
