B Appendix: Installer Silent Mode

In addition to the GUI and text interfaces of the Central Office installer, there is a silent mode that can be run. This mode is useful if you wish to run a new installation and use the settings you provided in a previous installation. It is also useful if you encounter errors during an installation and wish to continue after resolving them.

The installer runs in two distinct phases. The first phase involves gathering settings from the user. At the end of the first phase, a properties file named ant.install.properties is created with the settings that were provided and the cwallet.sso file is created. In the second phase, this properties file is used to provide your settings for the installation.

To skip the first phase and re-use the ant.install.properties and cwallet.sso files from a previous run, follow these instructions:

Edit the ant.install.properties file and correct any invalid settings that may have caused the installer to fail in its previous run.
If the previous install was successful, the cwallet.sso file is found in the installation directory for that install. Copy the cwallet.sso file to <INSTALL_DIR> for this silent install.
Run the installer again with the silent argument.
```
install.sh silent weblogic
```
After the installation is successfully completed, the CREATE SYNONYM privilege must be revoked. In the installer console window, it prompts for a database administrator to run the revokesyn SQL script to revoke the privilege. The script is found in the <INSTALL_DIR> directory.
