Prepare Linux for CA Business Intelligence Installation

Before you can install CA Business Intelligence on Linux, you prepare the computer for installation. You create a non-root user for the CA Business Intelligence installation, verify that the Oracle RDBMS is exposed to the installation of CA Business Intelligence and set the environment variables.

Follow these steps:

Log in as a root user.
Create a non-root user. The CA Business Intelligence installation requires a non-root user.
For example, enter the following commands to create a user named bouser that belongs to the group other:
```
groupadd other
useradd -d /home/bouser -g other -m -s /bin/bash -c bouser bouser
passwd bouser
```
When prompted, enter and confirm a password for the user you defined.
Verify that the LANG environment variable is configured as follows:
```
LANG=en US.utf8
```
Log in as the non-root user you created.
Enter the following commands to verify that the ORACLE_HOME and TNS_ADMIN environment variables are set correctly:
```
echo $ORACLE_HOME
echo $TNS_ADMIN
```
A non-empty output verifies that these environment variables are valid. For example:
```
/opt/oracle/app/oracle/product/10.2.0/client_1
/opt/oracle/app/oracle/product/10.2.0/client_1/admin/network
```
If you receive an empty output for the commands, verify that the variables are set for the non-root user you created. For example, edit /home/bouser/.profile as follows:
```
ORACLE_HOME=/opt/oracle/app/oracle/product/10.2.0/client_1
export ORACLE_HOME
TNS_ADMIN=$ORACLE_HOME/network/admin
export TNS_ADMIN
```
Verify that LD_LIBRARY_PATH for your non-root user contains the following paths:
```
$ORACLE_HOME/lib:$ORACLE_HOME/lib32
```
For example, type the following command and search the output for these paths:
```
echo $LD_LIBRARY_PATH
```
If these paths are missing, append them to LD_LIBRARY_PATH. For example, edit /home/bouser/.profile as follows:
```
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:$ORACLE_HOME/lib:$ORACLE_HOME/lib32
export LD_LIBRARY_PATH
```
Verify that the folders in LD_LIBRARY_PATH and TNS_ADMIN are accessible, as follows:
```
ls -l $ORACLE_HOME
ls -l $TNS_ADMIN/tnsnames.ora
```
The commands should not return a permission denied error. If they do, you must grant proper permissions. For example, the root/oracle user should run the following command:
```
chmod -R +xr $ORACLE_HOME
```

Verify that Oracle connectivity is valid, using the TNS Ping utility as follows:

$ORACLE_HOME/bin/tnsping service_name

The output from TNS Ping should look be similar to the following example:

TNS Ping Utility for Solaris: Version 10.2.0.1.0 - Production on 07-MAY-2008 09:17:02

You can now install CA Business Intelligence on Linux.
