安装 ORACLE 12C 单节点RAC

Posted on 2013 年 06 月 30 日 by 惜分飞

装过ORACLE 12C RAC 的朋友应该感觉到12C的RAC简直就是一个怪物,需要消耗太多的内存、IO、CPU资源,在没有物理机器的情况下,使用虚拟机装ORACLE 12C RAC那可能需要比较好的主机资源(8G的内存不运行主机,仅仅够2个节点的虚拟机运行,所以8G的内存主机基本上无法ORACLE 12C 2节点RAC),而没有好的资源情况下,又需要玩12C RAC功能的朋友,我这里展示了单节点RAC(一个节点的RAC的rac),这里主要显示的是单节点RAC和多节点RAC安装不同之处,同时这里的安装也仅仅是为了玩

在11GR2 GI上配置第二个监听

Posted on 2013 年 06 月 19 日 by 惜分飞

有客户因为归档日志量每天很大,为了不影响业务,需要配置一个单独的万兆网络来专门的传输归档日志到DG库,这里就涉及到在11G(11203 Linux) RAC中增加一个监听用来使用专门的网络.这里提供在主库配置第二个监听的整体操作过程,主要涉及配置解析,增加网络,增加vip,配置监听,配置listener_networks

0CRS-1002: Resource 'ora.rac1.vip' is already running on member 'rac2'

这里可以看出由于vip资源失败，致使lsnr资源也出现失败，紧接着又是启动vip，再启动lsnr。所以使得我们通过crs_stat -t观察资源情况时，看到这两个进程一直处于波动状态

分析ora.rac1.vip.log日志

[ora.rac1.vip]: clsrcexecut:env ORACLE_CONFIG_HOME=/u01/app/oracle/product/10.2.0/crs_1
[ora.rac1.vip]: clsrcexecut:cmd=/u01/app/oracle/product/10.2.0/crs_1/bin/racgeut -e 
_USR_ORA_DEBUG=0 54 /u01/app/oracle/product/10.2.0/crs_1/bin/racgvip check rac1
[ora.rac1.vip]: clsrcexecut: rc = 1, time = 6.430s
[ora.rac1.vip]: end for resource = ora.rac1.vip, action=check,status=1,time=6.450s
[ora.rac1.vip]: ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
[ora.rac1.vip]: clsrcstartorp: Error with malloc
[ora.rac1.vip]: ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
ping to 192.168.1.1 via eth0 failed, rc = 1 (host=rac1)
Interface eth0 checked failed (host=rac1)
Invalid parameters, or failed to bring up VIP (host=rac1)

通过这里发现:从eth0网卡ping192.168.1.1(网关)不通,导致VIP资源不能正常工作

核实问题原因/解决
我们人工从节点1上ping 网关(192.168.1.1),果真不通.继续检查发现,网关服务器上意外的开启了防火墙,对部分进来的包进行了过滤,恰好节点1在被禁止之列,使得节点1 ping 网关不成功,从而出现该了该错误.关闭防火墙或者重新设置规则后,rac工作正常,未出现vip和lsnr资源出现波动情况.

RAC 10g升级到10.2.0.5

Posted on 2012 年 04 月 02 日 by 惜分飞

1.Back Up database
一般情况下rman备份

2.备份ocr和vote disk

[root@rac2 bin]# ./ocrconfig -export /tmp/ocr_export.bak
[root@rac2 bin]# more /etc/oracle/ocr.loc 
ocrconfig_loc=/dev/raw/raw11
local_only=FALSE
[root@rac2 bin]# dd if=/dev/raw/raw11 of=/tmp/ocr_dd.bak
[root@rac2 bin]# dd if=/dev/raw/raw31 of=/tmp/vote_dd.bak

3.Update Oracle Time Zone Definitions
Actions for the DSTv4 update in the 10.2.0.5 patchset [ID 1086400.1]

4.Stopping All Processes
滚动升级关闭一个节点所有进程，非滚动升级关闭所有进程

$ isqlplusctl stop
$ emctl stop dbconsole
$ srvctl stop service -d db_name [-s service_name_list [-i inst_name]]
$ srvctl stop instance -d db_name -i inst_name
$ srvctl stop asm -n node
$ srvctl stop listener -n node [-l listenername]
$ srvctl stop nodeapps -n node
# CRS_home/bin/crsctl stop crs(root执行,滚动升级不需要关闭)

5.Back Up the System
$ORACLE_BASE中文件，主要包括(db和crs安装文件/oraInventory文件)

6.升级crs软件
执行./runInstaller选择crs目录

执行下面命令
# CRS_home/bin/crsctl stop crs
# CRS_home/install/root102.sh

7.升级db软件
关闭crs和db所有进程(步骤同4)
执行./runInstaller选择db目录

执行下面命令
# ORACLE_HOME/root.sh

8.升级数据库
8.1)检查数据库升级需要满足条件,对存在不合适之处,进行修正
