Document overview This document is a Storage Mirroring application note. An application note provides guidelines on the use of Storage Mirroring in a specific environment. This document contains: • Document overview—Explains what an application note contains, how it should be used, what you need to know before trying to use the application note, and where you can go for more information.
Solution overview Oracle is a scalable, reliable, flexible, and high-performance relational database management system for many server-based operating systems. Storage Mirroring provides real-time enterprise data protection and replication. Storage Mirroring can be used to provide high availability for Oracle. This document describes the steps necessary to configure Storage Mirroring to provide high availability for Windows® servers running Oracle 10g.
Modifying the sample script files After you modify the sample scripts, save them with a new name to remove the SAMPLE_ prefix. Copy the scripts to the directory where Storage Mirroring is installed. The sample batch files provided are only examples. Because no two environments or configurations are exactly the same, you MUST modify the sample scripts in order to make the solution work in your environment.
Sample implementation This section described an example of how to configure Storage Mirroring and Oracle. Use these procedures as a guideline for creating your own implementation. Because no two environments or configurations are exactly the same, you will probably need to implement additional or different steps than what is documented in order to Install software on the source. Install software on the source 1. Install Oracle on the source, if it is not already installed. 2.
example, if you used the default Oracle installation, your instance parameter file will be init.ora and located in the \oracle\product\10.x.x\admin\instance_name\pfile folder in the destination drive. If you supplied an instance name of prod, your init.ora file will be located in the \oracle\product\10.x.x\admin\prod\pfile folder by default. Files with unique names will be identified in the table with a wildcard asterisk (*).
NOTE: There is a unique numeric identifier at the end of the init.ora file (xxxxx) that uniquely identifies initialization files when there is more than one installed. Besides the initialization parameter file (init.ora), which is stored in a text format, administrators can choose to maintain the initialization parameters in a binary server parameter file (spfile.ora). This is installed by default The Listener service will not start on the target if listener.
Sample_postover.bat rem ## ***SAMPLE*** Oracle post-failover script rem ## This sample batch file is provided as an example only. Because no two rem ## environments or configurations are exactly the same, you MUST modify rem ## this script in order to make the solution work in your environment. rem ## This script makes the following two assumptions: rem ## 1. You have created a directory c:\oracle_fo rem ## 2. The dbx_start.
set ORACLE_SID=instance_name1 %ORACLE_HOME%\db_1\bin\sqlplus.exe "/ AS SYSDBA" <%ORACLE_FO%\db1_start.sql>%ORACLE_FO%\start_%ORACLE_SID%.log set ORACLE_SID=instance_name2 %ORACLE_HOME%\db_1\bin\sqlplus.exe "/ AS SYSDBA" <%ORACLE_FO%\db2_start.sql>%ORACLE_FO%\start_%ORACLE_SID%.log rem ## The following line starts the Oracle Listener service. The outcome is redirected to the rem ## failover directory where a log file is created. Check this log file for errors.
Sample_preback.bat rem ## ***SAMPLE*** Oracle pre-failback script rem ## This sample batch file is provided as an example only. Because no two rem ## environments or configurations are exactly the same, you MUST modify rem ## this script in order to make the solution work in your environment. rem ## This script makes the following two assumptions: rem ## 1. You have created a directory c:\oracle_fo rem ## 2. The db_stop.
3. Select Start, Programs, Storage Mirroring, Failover Control Center. 4. Select the target machine from the list of available machines. If the target you need is not displayed, click Add Target, enter the machine name, and click OK. 5. Click Login to login to the selected target. 6. To add a monitor for the selected target, click Add Monitor. Type the name of the source machine and click OK. The Monitor Settings window will open. 7.
3. f you must rebuild your hard drive, complete the following. If you do not need to rebuild your hard drive, skip this step and continue with step 4. a. Install Windows. Since your source machine is not connected to the network, go ahead and use the source’s original name and IP address. b. Install Storage Mirroring using the installation defaults. c. Install Oracle using the installation settings previously used. 4. Disable all of the NICs on the source. 5.
• Restore To—The name of the machine where the data will be restored. This is your temporary source that has the unique IP address. 14. Identify the correct drive mappings for the data and any other restoration options necessary. For detailed information on the restoration options, see the Storage Mirroring User’s Guide. 15. Verify that the selections you have made are correct and click Restore to begin the restoration.
