We have tested Joget Workflow v3 with Oracle 10g Express, and generally it ran fine. However, if you have found any issue, please feel free to [inform the community through forum discussion|FORUM:Running Joget Workflow with Oracle].
# Create a database schema in Oracle, name it as jwdb (or other preferred name).
# Download jwdb_oracle.sql, and load this SQL file to "jwdb" schema. This will populate all necessary Joget Workflow table structure into "jwdb".

1. In joget-installation-directory/wflow/, create a new datasource profile file - app_datasource-oracle.properties
2. Open to edit joget-installation-directory/wflow/app_datasource-oracle.properties in text editor, and insert contents as shown in Figure 1 below. You may need to edit the configurations (such as datasource URL, database user/password) according to your environment.
3. Open to edit joget-installation-directory/wflow/app_datasource.properties in text editor, and change the content to as shown in Figure 2 below. This is to activate the datasource profile named "oracle".
4. Restart Joget Workflow server.

Figure 1: Datasource Profile Configurations

workflowUser=jwdb
workflowPassword=jwdb
workflowDriver=oracle.jdbc.driver.OracleDriver
workflowUrl=jdbc\:oracle\:thin\:@hostname\:1521\:XE

Each profile contains 5 datasources. So, as shown above, each property (such as datasource URL) repeats 5 times.

You may need to change the datasource URL, database user, and database user's password accordingly.

currentProfile=oracle
