网关不通致使vip/lsnr资源异常

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

发表于 2012 年 4 月 2 日 由 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
How to Download and Run Oracle’s Database Pre-Upgrade Utility [ID 884522.1]

SQL> STARTUP UPGRADE
SQL> SPOOL upgrade_info.log 
SQL> @/rdbms/admin/utlu102i.sql
SQL> SPOOL OFF
SQL> ALTER SYSTEM SET CLUSTER_DATABASE=FALSE SCOPE=spfile;
--其他根据upgrade_info.log中提示修改
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP UPGRADE

8.2)启动监听
srvctl start listener -n node

8.3)升级数据库

SQL> SPOOL patch.log
SQL> @?/rdbms/admin/catupgrd.sql
--检查patch.log，发现有错误查找原因，重新执行catupgrd.sql脚本
SQL> SPOOL OFF
SQL> SHUTDOWN IMMEDIATE
SQL> STARTUP
SQL> @?/rdbms/admin/utlrp.sql
SQL> ALTER SYSTEM SET CLUSTER_DATABASE=TRUE SCOPE=spfile;
--包括其他修改调整参数
SQL> SHUTDOWN IMMEDIATE
--使用rac管理相关命令，启动需要启动资源

9.修改相关目录权限
# ORACLE_HOME/install/changePerm.sh

具体操作步骤请阅读README.html
