■ Extent fragmentation

As files are created and removed, the free extent map for an allocation unit

changes from having one large free area to having many smaller free areas.

Extent fragmentation occurs when files cannot be allocated in contiguous

chunks and more extents must be referenced to access a file. In a case of

extreme fragmentation, a file system may have free space that cannot be

allocated.

Starting an Oracle database instance

You can start an Oracle database instance or a cloned Oracle database from the

GUI. You must know the password of the database owner. The steps to restart an

Oracle database instance are the same.

To start an Oracle database instance or a cloned Oracle database instance

Access the Oracle Start Up Database wizard.

See “To access Oracle database wizards in the Java GUI” on page 26.

See “Accessing database management tasks in the Web GUI” on page 34.

Enter the Oracle SID, Oracle home, and Owner information. Click Next to

continue.

Enter your password and optionally enter Oracle pfile information, then click

Start Database. The UNIX user name field is populated automatically and

the other fields on this screen are read-only.

At the confirmation prompt, click Yes to confirm that you want to start the

database.

If the Oracle database was successfully started, you will receive a confirmation

message. Click OK to continue.

Starting an Oracle snapshot database instance

If you created a snapshot using the Database FlashSnap feature, you can start an

Oraclesnapshot database from the secondary host. This is the equivalent of cloning

the database from the primary host. You must know the password of the instance

owner and there must be an existing snapshot.

See “Database FlashSnap in the GUI” on page 73.

■ Make sure you have enough space to create a clone database on

your system.

■ You must have an existing snapshot.
