To ensure optimum performance when you are using ARIS with the standard database system, we recommend that you regularly shrink the database. This prevents that the used disk space constantly increases. To do so, execute the vacuumdb.exe file (<ARIS installation directory>\server\bin\agentLocalRepo\.unpacked\<build number>_PostgreSQL-run-prod-<ARIS version>-windows64-runnable.zip\postgresql\bin). For detailed information, read the instructions provided by the manufacturer.
