[Script] Oracle Control File Move Add Delete Multiplex

Oracle maintains control file Controlfile related scripts (moving, adding, deleting, multiplexing operations)

-- 1- When the database uses the PFILE parameter file, use this method to maintain the control file
-- 1.1 View the parameter file type used by the current database

SQL> SHOW PARAMETER PFILE;
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /home/oracle/product/11gR2/dbs/spfileora11g.ora

SQL> SHOW PARAMETER SPFILE;
 
NAME                                 TYPE        VALUE
------------------------------------ ----------- ------------------------------
spfile                               string      /home/oracle/product/11gR2/dbs/spfileora11g.ora

-- 1.2 View the current database control file layout status
