Goal
What are the steps to move the RAC database ORACLE_HOME from one location(filesystem) to another one?
This note is for database home only and does not apply to CRS or GI home.
Solution
Execute all the following as database user:
Solution 1:
1. Install a new set of RAC binaries with OUI into a new home
2. Apply all patches that have been installed in the old home, use "opatch lsinventory" to compare the old and new home once all patches are applied.
3. Copy over init{ORACLE_SID}.ora in dbs directory from the old home to the new home on all nodes
4. Copy over network files (listener.ora, tnsnames.ora, and sqlnet.ora) in network/admin directory from the old home to the new home on all nodes
5. Shutdown the database with srvctl from the old database home: srvctl stop database -d
6. Modify the database resource as with srvctl from the old database home: srvctl modify database -d -o
7. Start the database with srvctl from the new database home: srvctl start database -d
Solution 2: (Clone)
1. Copy existing RAC binaries to a new location and keep the same ownership/permission on any node: cp -rp
2. Execute:
3. Extend the new home to other nodes:
4. Go to Step3 of "Solution 1"

Oracle View Encryption allows you to encrypt data in the view, thereby enhancing the security of sensitive information. The steps include: 1) creating the master encryption key (MEk); 2) creating an encrypted view, specifying the view and MEk to be encrypted; 3) authorizing users to access the encrypted view. How encrypted views work: When a user querys for an encrypted view, Oracle uses MEk to decrypt data, ensuring that only authorized users can access readable data.

Deleting all data in Oracle requires the following steps: 1. Establish a connection; 2. Disable foreign key constraints; 3. Delete table data; 4. Submit transactions; 5. Enable foreign key constraints (optional). Be sure to back up the database before execution to prevent data loss.

Solutions to Oracle cannot be opened include: 1. Start the database service; 2. Start the listener; 3. Check port conflicts; 4. Set environment variables correctly; 5. Make sure the firewall or antivirus software does not block the connection; 6. Check whether the server is closed; 7. Use RMAN to recover corrupt files; 8. Check whether the TNS service name is correct; 9. Check network connection; 10. Reinstall Oracle software.

Oracle database paging uses ROWNUM pseudo-columns or FETCH statements to implement: ROWNUM pseudo-columns are used to filter results by row numbers and are suitable for complex queries. The FETCH statement is used to get the specified number of first rows and is suitable for simple queries.

The method to solve the Oracle cursor closure problem includes: explicitly closing the cursor using the CLOSE statement. Declare the cursor in the FOR UPDATE clause so that it automatically closes after the scope is ended. Declare the cursor in the USING clause so that it automatically closes when the associated PL/SQL variable is closed. Use exception handling to ensure that the cursor is closed in any exception situation. Use the connection pool to automatically close the cursor. Disable automatic submission and delay cursor closing.

In Oracle, the FOR LOOP loop can create cursors dynamically. The steps are: 1. Define the cursor type; 2. Create the loop; 3. Create the cursor dynamically; 4. Execute the cursor; 5. Close the cursor. Example: A cursor can be created cycle-by-circuit to display the names and salaries of the top 10 employees.

To stop an Oracle database, perform the following steps: 1. Connect to the database; 2. Shutdown immediately; 3. Shutdown abort completely.

SQL statements can be created and executed based on runtime input by using Oracle's dynamic SQL. The steps include: preparing an empty string variable to store dynamically generated SQL statements. Use the EXECUTE IMMEDIATE or PREPARE statement to compile and execute dynamic SQL statements. Use bind variable to pass user input or other dynamic values to dynamic SQL. Use EXECUTE IMMEDIATE or EXECUTE to execute dynamic SQL statements.
