    Finding Oracle SID
 What to update in the ‘config.txt’ file for deploying Canvas?

The ‘config.txt’ file contains the configuration details to connect to the database and execute the schema scripts of Canvas Technology framework. It is essential that you provide the correct DBA user ID and password in the ‘config.txt’ file to connect to the Oracle database. The Canvas schema scripts are executed on the connected database.

Updating config.txt file


 Why is the Canvas schema script running thrice when executing the ‘run.bat’ file?

It is because, by default the ‘run.bat’ file executes the schema scripts of CT ModelHouse, Expert Studio, and Wizard Studio. However, you can specify which scripts to be executed in the APP_LIST parameter in the 'config.txt' file by removing the unwanted schemas:

APP_LIST=ctmodelhouse, ctstudio/Expert, ctstudio/Wizard
