# Editing the etl.properties file and installing the ETL utility again

If you need to install the ETL utility subsequent times after the first installation, you must first drop the destination account.

Step 1. Edit the etl.properties file.

1. In a command shell, set your current directory to the location where you unpacked the installation ZIP file, Healthcare-CDM4_ETL_xxx.zip, where xxx refers to the build number.

   For example:

   $ cd /u01/stage/cdm4etl

2. Open the etl.properties file in a text editor, such as vi.
3. Provide values for the settings in the etl.properties files. For descriptions of each property, see Setting installation and data transfer settings.

Step 2. Drop the destination account.

1. In the command shell, log in to the Empirica Healthcare Analysis database using a privileged user, such as sys or system. The user must have privileges to create a user and grant privileges to the user.

   For example:

   $ sqlplus <privileged_user_name>@<connect_string>

   You are prompted to type a password for the user.

2. Type a password, and press Enter.
3. Drop the destination account using the following command:

   Note: Drop the destination account, which the ETL utility created, not the account that was created when you installed the Empirica Healthcare Analysis application. You must type the user name for the account correctly. You cannot recover a dropped account.

   SQL> drop user <user_name> cascade;

   Example:

   SQL> drop user CDM_DEST cascade;

Step 3. Install the ETL utility again.

1. In a command shell, set your current directory to the location where you unpacked the installation ZIP file, Healthcare-CDM4_ETL_xxx.zip, where xxx refers to the build number.

   For example:

   $ cd /u01/stage/cdm4etl

2. In the command shell, log in to the Empirica Healthcare Analysis database using a privileged user, such as sys or system. The user must have privileges to create a user and grant privileges to the user.

   For example:

   $ sqlplus <privileged_user_name>@<connect_string>

   You are prompted to type a password for the user.

3. Type a password, and press Enter.
4. In SQL*Plus, execute the installation script, install_etl.sql. This file is in the installation kit.

   SQL>@install_etl.sql

   If you set properties so that you import using a database link, the installation prompts you to provide and confirm the passwords for the data and vocabulary accounts in the source database.

   For all installations, the installation prompts you to create a password for the destination account. Remember this value for later when you check whether the installation was successful and execute the ETL utility.

   The install_etl.log file, which is in the current directory, is overwritten when you reinstall.
