Preparing to migrate
Perform the following steps before you migrate the database.
To prepare the systems for migration
- Enable archivelog mode on the source database.
Shut down the database instance if it is open.
Restart the instance with the mount option.
SQL> startup mount ORACLE instance started.
Enable the archivelog mode.
SQL> alter database archivelog; Database altered.
Open the database.
SQL> alter database open; Database altered.
- Create a VxFS file system on the volume and mount it.
For Mounting a VxFS file system. SeeStorage Foundation Cluster File System High Availability Administrator's Guide
Create a cluster-wide mount point for a RAC environment for administering CFS. SeeStorage Foundation Cluster File System High Availability Administrator's Guide
Note:
Ensure that the size of the file system is as large as the source database.
- Set up passwordless SSH between the root users of the source and target systems.
- Install the DBD::ORACLE perl module on the target systems, using the PERL binary which is present in the Oracle Home directory.
For instructions, see the Perl documentation.
- Set the following environment variables - ORACLE_HOME and LD_LIBRARY_PATH:
# export ORACLE_HOME=path of oracle_home # export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$ORACLE_HOME
- Keep the following information handy:
Oracle base directory path of the target system
Name of the source database
Any instance name of source database
Name of the target database
Name of all target database instances
Name of the source database host
Host name of all target instances
VxFS mount point
Destination path of the recovery files
Password of system user and sys user for the source databases
Absolute path of the configuration file.
