How to Run Ispirer SQLWays Wizard in a Parallel Mode
When Parallel Mode Can Be Useful
Running Ispirer SQLWays Wizard tool in a parallel mode can be quite useful when:
- Migrating a huge database with a great number of SQL objects and data
- Migrating a great number of databases
- Migrating one very huge table.
In these cases you may optimize the migration process by running the tool in a parallel mode. It may significantly speed up the migration.
How to Run Migration in a Parallel Mode
To migrate in a parallel mode you just need to run several instances of Ispirer SQLWays Wizard tool. For example, launch the first process of Ispirer SQLWays Wizard and specify the set of objects that should be migrated during the first process. Then launch the same tool again and specify another set of objects or another database for conversion. So you can run as many processes as required, but please note that it's important to have powerful working environment to be able to run more than 5 processes of Ispirer SQLWays Wizard.
Please also note that each instance of Ispirer SQLWays Wizard should have its own project directory, like it is shown on the screenshot:
Ispirer Recommendations
- We recommend to divide the whole migration scope into the sets of objects that are independent from each other.
- If you are migrating a huge database or one table in separate processes, we recommend to divide the data into approximately equal parts for each migration set.
