Use the following procedure to restore OCR on UNIX-based systems: Identify the OCR backups by using the ocrconfig -showbackup command. You can execute this command from any node as user oracle. The output tells you on which node and which path to retrieve automatically generated backups. Review the contents of the backup by using ocrdump -backupfile file_name , where file_name is the name of the backup file. Stop Oracle Clusterware on all the nodes of your cluster by executing the crsctl stop crs command on all the nodes as the root user. Perform the restore by applying an OCR backup file that you identified in step one using the following command as the root user, where file_name is the name of the OCR file that you want to restore. Make sure that the OCR devices that you specify in the OCR configuration file (/etc/oracle/ocr.loc) exist and that these OCR devices are valid before ...

Step to Install - Oracle 10G Silent Installation Step :- Pre-requisites Kernel Paramters settings and Creation of Oracle user and groups. Step :- Mount CD or allocate Oracle software as per requirment. Step :- To create a response file, start the OUI with the following command and perform an installation as normal. ./runInstaller -record -destinationFile /tmp/10gR2.rsp Description :- The "-record" parameter tells the installer to write to the response file and the "-destinationFile" parameter defines the name and location of the response file.The response files are quite large, containing a large number of parameters and comments. The 10gR2.rsp file is an example of a response file from an Oracle Database 10g installation generated by the previous command. Step :- A silent installation is initiated using the following command. ./runInstaller -silent -responseFile /tmp/10gR2.rsp Description :- The "-silent" parameter indicates that this is a silent in...

Solution To Flashback primary database execute following steps : 1. Shutdown primary database . SQL> SHUTDOWN IMMEDIATE 2. Start primary database in mount stage SQL> STARTUP MOUNT 3. Flashback primary database to specified scn SQL> FLASHBACK DATABASE TO SCN <scn_number>; 4. Open primary database with reset logs. SQL> ALTER DATABASE OPEN RESETLOGS; 5. Cancel media recovery on the standby database. SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL; 6. Check current_scn on the standby database, If flashback scn is greater then current_scn then skip next step (step 7). SQL> SELECT CURRENT_SCN FROM V$DATABASE; 7. Flashback Standby database SQL> FLASHBACK STANDBY DATABASE TO SCN <scn_number -2>; (on standby database) 8. Start managed recovery on the standby database . SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE DISCONNECT FROM SESSION;
