Port Oracle databases in Windows to Linux

After that, the database and instance names on the linux Server are changed from uppercase ORCL to lowercase orcl, and all the parameter files and password files are modified to decompress the cold backup.

After that, the database and instance names on the linux Server are changed from uppercase ORCL to lowercase orcl, and all the parameter files and password files are modified to decompress the cold backup.

Install a Windows 2008 Server 64 and Oracle, and then migrate the database to the Linux environment
Windows Server 2008-192.168.182.128 Oracle 11.2.0.3.0 ORACLE_SID = orcl
Oracle Enterprise Linux 5.8-192.168.182.131 Oracle 11.2.0.1.0 ORACLE_SID = ORCL

The process is the same as migrating a 10g Database to 11g. When modifying the control file script, you must modify the path and database name.
