RedHat Password encryption in RHEL

I am working on a script where we are using sqlplus command to connect to Oracle DB. But the schemaname and password used for sqlplus authentication, have to be hardcoded in the script.

Code:
DBconnection=scott/tiger@SID
sqlplus $DBconnection

Here any user who reads the script can read the password of Oracle DB schema . Is there any way (apart from Oracle Wallet) we can hide the password from this script?

I tried creating a separate file having DBconnection variable defined inside it but its of no use as the user can source that file and read the variable's value.


Regards,
Abhishek

capture-schema(1m)					    Application Server Utility						capture-schema(1m)

NAME
capture-schema - stores the database metadata (schema) in a file for use in mapping and execution SYNOPSIS
capture-schema-dburl url-username name- password password-driver a_jdbc_driver [-schemaname name] [-table tablename]* [-out filename] Stores the database metadata (schema) in a file. You can also use the Sun Java System Studio IDE to capture the database schema. Run cap- ture-schema as the same database user that owns the tables, so that the -username and -schemaname options are given the same username. Additionally, you can grant the database user running the capture-schema command the ANALYZE ANY TABLE privilege. OPTIONS
-dburl JDBC URL expected by the driver for accessing a database. -username user name for authenticating access to a database. -password password for accessing the selected database. -driver JDBC driver classname in your CLASSPATH. -schemaname name of the user schema being captured. If not specified, the default will capture metadata for all tables from all the schemas accessible to this user. Specifying this parameter is highly recommended. If more than one schema is accessible to this user, more than one table with the same name may be captured which will cause problems. -table name of the table; multiple table names can be specified. -out output target; defaults to stdout. This parameter corresponds to the schema sub-element of the sun-cmp-mapping ele- ment in the sun-cmp-mapping_1_1.dtd file. EXAMPLES
Example 1: Using capture-schema capture-schema -dburl jdbc:oracle:thin:@sadbuttrue:1521:ora817 -schemaname cantiflas -username CANTIFLAS -password enigma -driver oracle.jdbc.driver.OracleDriver asadmin(1M) Sun Java System Application Server March 2004 capture-schema(1m)
