Run the preinstallation script

Run the preinstallation script to verify your readiness to install Oracle.

Procedure

As root, change directory using the following command:
systems:
```
# cd <DIST_DIR>/proviso/SOLARIS/DataBase/SOL10/oracle/instance/ora_installer
```
systems:
```
 # cd <DIST_DIR>/proviso/AIX/DataBase/AIX<version_num>/oracle/instance/ora_installer
```
systems:
```
# cd <DIST_DIR>/proviso/RHEL/DataBase/RHEL<version_num>/oracle/instance/ora_installer
```
where:

<DIST_DIR> is the directory on the hard drive where you copied the contents of the Tivoli® Netcool® Performance Manager distribution in Download the Oracle distribution to disk.
Set the ORACLE_BASE environment variable. For example:
```
# ORACLE_BASE=/opt/oracle
# export ORACLE_BASE
```
Note: You must use the same ORACLE_BASE setting that you specified in “Run the Oracle server configuration script”.
Enter the following command:
```
# ./pre_install_as_root
```
The following messages indicate success:
```
Checking that you are logged in as root --> Ok.
Checking ORACLE_BASE --> Ok.
Checking oraInst.loc file --> Ok.
```
If the script shows an error, correct the situation causing the error before proceeding to the next step.
