Backing Up and Recovering Oracle Airlines Data Model

Backing up and recovering Oracle Airlines Data Model involves a two-step process to 1) backup or recover the relational objects, and 2) backup or recover the analytic workspace that is part of Oracle Airlines Data Model. These steps are outlined in the following topics:

Exporting Oracle Airlines Data Model
Importing Oracle Airlines Data Model

Exporting Oracle Airlines Data Model

Take the following steps to backup Oracle Airlines Data Model:

Backup the OADM_SYS schema by executing the expdp utility.

This utility exports all physical tables containing the data and trained mining models. For more information, see Oracle Database Utilities.
Backup the analytic workspace that is part of the Oracle Airlines Data Model. The analytic workspace is backed up as an EIF file, named OADM_BAK.EIF, which is generated under the ORACLE_HOME/oadm/pdm/olap directory.
1. Connect to the Database with oadm_sys.
2. Issue the following SQL statements.
```
exec dbms_aw.execute('AW ATTACH OADM');
exec dbms_aw.execute('CDA OADM_OLAP_DIR');
exec dbms_aw.execute('EXPORT ALL TO EIF FILE ','OADM_BAK.EIF',' NOTEMPDATA');
exec dbms_aw.execute('AW DETACH OADM');
```

Importing Oracle Airlines Data Model

Take the following steps to restore Oracle Airlines Data Model from the backup files:

Restore the OADM_SYS schema by executing the impdp utility.

This utility imports all physical tables containing the data and trained mining models. For more information, see Oracle Database Utilities.
Connect to the Database with oadm_sys, and import the analytic workspace that was saved as an EIF file, named OADM_BAK.EIF, under the ORACLE_HOME/oadm/pdm/olap directory.
```
exec dbms_aw.execute('IMPORT ALL TO EIF FILE ', 'OADM_BAK.EIF');
```

Overview: Deinstalling Oracle Airlines Data Model

To deinstall Oracle Airlines Data Model, you do not simply run Oracle Universal Installer in deinstall mode. Instead, you perform the following tasks:

Backup Oracle Airlines Data Model, as described in "Exporting Oracle Airlines Data Model".
Stop any sessions that use the Oracle Airlines Data Model schemas, as described in "Pre-Deinstallation Tasks".
Execute the deinstallation script, as described in "Deinstallation Script Execution".
If you are deinstalling the sample reports, perform the tasks described in "Post-Deinstallation Tasks".

Note:
To deinstall Oracle Airlines Data Model, you do not simply run the Oracle Universal Installer in deinstall mode.

Pre-Deinstallation Tasks

The deinstallation script removes the oadm_sys schema. Consequently, before you run the deinstallation script, ensure that there are no active sessions that connect to the oadm_sys schema.

Identifying if the oadm_sys schema is active

To identify if there are active sessions connecting to these schemas take the following steps:

Execute the following SQL statements:

select SID,SERIAL# from v$session where USERNAME='OADM_SYS';

If this query returns a session ID, then there is an active session.

Ending an active oadm_sys schema session

To end an active session, execute the following statements in which you replace sid and serial are the session ID and serial number returned by the earlier queries.

alter system kill session 'sid,serial' ;

Deinstallation Script Execution

To execute the Oracle Airlines Data Model deinstallation script:

Set the ORACLE_HOME to the location of the Database on which to deinstall Oracle Airlines Data Model.

For example, suppose that Oracle Home is in the directory /loc/app/oracle/product/11.2/

In a Bourne, Bash, or Korn shell, use these commands to set ORACLE_HOME:
```
$ ORACLE_HOME=/loc/app/oracle/product/11.2/
$ export ORACLE_HOME
```
In a C shell, use this command to set ORACLE_HOME:
```
% setenv ORACLE_HOME /loc/app/oracle/product/11.2/
```
Execute the Oracle Airlines Data Model deinstallation script:

$ORACLE_HOME/oadm/oadm_deinstall.sh
When prompted, enter the SYSTEM password.

The script de-configures Oracle Airlines Data Model and executes the Oracle Universal Installer in deinstall silent mode.

If you are deinstalling the sample reports, after the deinstallation script runs, perform the tasks described in "Post-Deinstallation Tasks".

Post-Deinstallation Tasks

If you are deinstalling the Oracle Airlines Data Model sample reports, follow these steps to perform additional cleanup:

Delete oadm.rpd in the directory BIHome/Server/Repository.
Delete the oadmwebcat folder in BIDataHome/web/catalog.
Delete the following line from BIHome/Server/Config/NQSConfig.INI:
```
Star    =    oadm.rpd, DEFAULT
```
