Power Database Fields FAQ

What should I do if I installed an incompatible version?
Power Database Fields PRO™ 4.0 is compatible with Jira 7.X.
If you have installed DBCF 3.0.x on Jira 7.x or DBCF 3.1.x / DBCF 4.0.x on Jira 6.x, perform the following steps:
- Uninstall SIL Engine™.
- Uninstall Power Database Fields PRO™.
- Install the version of Power Database Fields PRO™ that is compatible with your Jira.
SIL Engine™ should get updated automatically and should now have the correct version as well.
After you uninstall SIL Engine™, some plugins might remain disabled, so you might need to re-enable them manually.
I have a large DB with about 30K records and I experience performance issues
Power Database Fields PRO™ app was not designed for dealing with large amount of data. Sometimes, our users reported issues when more than ~10k records were retrieved by the sql queries. This doesn't mean that the app will not work with more than 10K records, it's just that you might experience certain issues with performance and data retrieval.
We plan to enhance the app to take care of such cases as well.
I have a huge list in my database and it takes some time to display options
Power Database Fields PRO™ runs an SQL query every time when a user tries to pull up a screen that contains one of the custom fields. The performance of the custom field cannot exceed the performance of the query when run directly from the database. So, if you have a query that takes 10 seconds to run when running from the database console it will take 10 seconds to run for the custom field. So for instance if you have 5 thousand users who are running a 10-second query every time they go to create a new issue or edit an issue this might have an impact on the performance of the database and increase the response time of Jira when it is running its own queries against the database. This would be true of any database plugin custom field, not just those developed by Cprime.
There are some design changes that could be used to mitigate the performance risks. For example, you could run the custom fields from a database cluster that is separate from the main Jira database. Also, using normalization on the tables and indexes targeted to the way the custom fields will be searching the tables will increase the performance of the custom fields.
Database custom fields don't work on Jira 7.X
After updating to Jira 7, some user experienced the following error (Error rendering 'databaseinput') when using SQL Server databases or the custom fields simply didn't work when using PostgreSQL databases.
I experience difficulties using special characters
When users of the Power Database Fields PRO™ use another language than English and it contains special characters, some translation might happen at the JDBC driver level. To avoid this, ensure that the translation between char codes doesn't happen.
How can I use a custom field value in the SQL query?
Most of Power Database Fields PRO™ users are usually using some custom fields in their queries to filter the data returned from the database. We're assuming that you have already created a database custom field at this point.
