sqlDoInstall will help you to install new SQL scripts and keep track of the versions applied to your Oracle database. Freeware

sqlDoInstall 1.6 allows you to rerun a failed script and restart from the point where it has failed in a previous run. It does not apply a driver+script combination that has been installed successfully. The "driver" and the supplied SQL uniquely identifies your script across the database. It'll create two tables: driverinst contains details, and driverinst_head contains a summary of the installation process. SQL installation, schema upgrades, and version tracking are easy.
