TheOraClusterNotes

Oracle db "cluster" in CNTV senario, notes:


-* Make it a document for express the structure, method, steps, maintain and attention *-






Install Oracle 11g 64bit, Capture the installation steps, record the password settings and db files path in the installation wizard


-* "CNTVDB" is the db instance name


//test the installation
cmd


sqlplus /nolog


connect system/CNTVdb123 as sysdba


Create a SIMPLETABLE for test
or
select * from all_users;


quit
/////////////////////////////////////////


-* stop oracle services (OracleDBConsoleorcl2,OracleServiceORCL2,OracleVssWriterORCL2)
-* change startup user to administrator:root1234


//make sure the user has the right for the net disk
-* change startup mode to manual


停止OracleService将control文件copy到 指定的共享磁盘路径下


启动OracleService服务
-* start OracleServiceCNTVDB service


//Change the db control files path
// !!! make sure the path is which you want use
cmd
sqlplus /nolog


SQL>connect system/CNTVdb123 as sysdba


Create a SIMPLETABLE for test
or
SQL>select * from all_users;


copy 'D:\oracle11g\oradata\CNTVDB\CNTVDB\CONTROL01.CTL','D:\oracle11g\oradata\CNTVDB\CNTVDB\CONTROL02.CTL' to '\\172.16.103.6\103.6cifs\ora_151_157\dbdata\oradata\CNTVDB\'




SQL>alter system set control_files='\\172.16.103.6\103.6cifs\ora_151_157\dbdata\oradata\CNTVDB\CONTROL01.CTL',
'\\172.16.103.6\103.6cifs\ora_151_157\dbdata\oradata\CNTVDB\CONTROL02.CTL' scope=spfile;
系统已更改。


--alter system set control_files='D:\oracle11g\oradata\CNTVDB\CNTVDB\CONTROL01.CTL','D:\oracle11g\oradata\CNTVDB\CNTVDB\CONTROL02.CTL' scope=spfile;






SQL>shutdown  如果shutdown一直卡在这里  就用另一种STOP OracleServiceCNTVDB 把service强行停掉




-- copy D:\oracle11g\oradata\CNTVDB\ folder to \\172.16.103.6\103.6cifs\ora_151_157\dbdata\oradata\CNTVDB


// change the db files path
// !!! make sure the path is which you want use

-* stop oracle services


do it again in the other machine


!!!attention: You can NOT startup both machine's oracle service in same time, if so, there should be unknown risk!




the rest work:


load all of data(tables & db config partations settings users) to this oracle environment, redirect the 1_webapp 2_etl 3_webfocus programs point to this oracle environment, test the 2 WORK LINES


For the "faild over" achievement, considers backup strategy
