This chapter provides information on backing up and recovering
your database.
Specific topics discussed are:
Backing up and recovering your Oracle8 database is one of
the most critical operations that a database administrator (DBA) performs.
For this reason, it is extremely important to choose the correct tools.
The table below describes available backup and recovery tools and makes
recommendations on which tool to use with your Oracle8 database:
Tool | Description | Analysis of Tool | To Use this Tool, See... |
---|---|---|---|
Oracle Enterprise Manager Backup Manager |
The Oracle Enterprise Manager Database Application Tools include a Backup Manager for backing up and recovering your Oracle8 database. The Backup Manager:
The Backup Manager enables you to back up and recover your database through a graphical user interface (GUI). This GUI enables you to use either of the two backup subsystems: |
Highly recommended for backing up and recovering your Oracle8 database because of capabilities and ease of use. Works in conjunction with Recovery Manager (RMAN80.EXE). Backing up to tape requires an optional media management layer (MML) from a third-party vendor, such as Legato Storage Manager (LSM). |
|
Recovery Manager (RMAN80.EXE) in command line mode |
Recovery Manager in command line mode is an Oracle8 tool that manages the process of backing up, restoring, and recovering files. Recovery Manager is automatically installed with Oracle8 Utilities. Recovery Manager uses a special PL/SQL interface to the server for invoking backup functions. The user is unaware of this interface and instead interfaces only with a command line. |
Command line usage only. Must clearly understand the command line syntax described in Oracle8 Backup and Recovery before using. Backing up to tape requires an optional MML from a third-party vendor. |

Third-party vendor products |
Third-party vendors such as Legato provide tape backup software that works with Backup Manager and RMAN80.EXE. |
Can back up to tape. Contact your third-party vendors for additional information. |
Legato Storage Manager Administrator's Guide and other third-party vendor documentation. |
NT Backup Manager and NT Recovery Manager (GUI tools) |
NT Backup Manager and NT Recovery Manager are Oracle tools that enable you to perform database backups to disk or tape. Both tools are automatically installed with the Oracle8 Utilities. |
Can back up to 4mm tape. Can perform hot and cold backups. This is the last release of this product on Oracle8. |
Online help included with these tools. |
OCOPY80 |
An Oracle executable that behaves like Windows NT's XCOPY command. OCOPY80 is needed when performing a hot backup manually (that is, backing up a tablespace that is in offline backup mode). |
Command line usage only. Can back up only to disk. Can only perform local backups. |
"Backing Up Files with OCOPY80" and "Recovering Files with OCOPY80" in this chapter. |
Use OCOPY80 for both hot and raw database file backups of
the following file types:
This table describes the two copy modes in which to use OCOPY80:
This table describes the syntax to use when backing up all
file types to hard disk or multiple diskettes:
Note: Always use a fresh diskette for each OCOPY80 procedure; do not use OCOPY80 to back up a file onto a diskette that contains part or all of another file backed up using OCOPY80. |
The table below describes the syntax to use when recovering
all file types from hard disk or multiple diskettes.
Restore From... | File Type to Restore | Syntax |
---|---|---|
Hard Disk1 |
FAT or NTFS files |
Use the Windows NT COPY command. |
|
Logical raw |
C:\> OCOPY80 new_file \\.\c: |
|
Physical raw |
C:\> OCOPY80 new_file \\.\physicaldriveN |
Multiple diskettes2 |
FAT or NTFS files |
C:\> OCOPY80 /R a: restore_dir Note: First insert the diskette containing the initial part of the backed up file. |
|
Logical raw |
C:\> OCOPY80 /R a: \\.\c: |
|
Physical raw |
C:\> OCOPY80 /R a: \\.\physicaldriveN |
1 These
are files originally backed up without the /B option.
2 These are files originally backed up with the /B option. |
When running backups to tape drivers using Legato Storage
Manager (LSM), LSM's BIN directory must be added to the PATH. The default
location of the directory is C:\WIN32APP\NSR\BIN.
To add this directory to the PATH:
The System Properties dialog box appears.
The Environment view appears.
