If you have problems with the database, note the following points:
Database-typical connection problems
Connection problems with databases can occur as follows:
- Incorrect information about the database in the config file, such as incorrect or incorrect entries for dbuser, dbpost, dbpasswd or dbpassword.
- Database is under load.
- Too many connections simultaneously (18 connections per user possible) Existing (not closed) database connections are terminated with a timeout after 60 seconds of inactivity. In principle, however, it is recommended to write scripts in such a way that opened database connections are closed again.
In principle, external access to a database is not possible. However, there is the possibility that shared packages can access shared databases of other contracts.
