  • We have added a new SQL Stats Explorer report for Oracle users. This will be rolled out to to other platforms in upcoming releases. It allows reporting of SQL statistics over time for the Top n statements.
  • DBmarlin server now comes with updated versions of Java, Tomcat, PostgreSQL and TimeScaleDB containing the latest security updates and bug fixes.
  • DBmarlin server now bundles timescaledb-tune which can be run to optimise the DBmarlin PostgresSQL and TimeScaleDB settings for better performance. There are wrapper scripts for Window and Linux under scripts/dbadmin. You can run --yes (Linux) or timescaledb-tune.bat --yes (Windows) to automatically apply all suggested parameter changes and then restart PostgreSQL.
  • DBmarlin server on Windows now has a default Tomcat Heap size of 1GB and max of 2GB. For larger installations the size can be increased further by running tomcat\bin\DBmarlinTomcatw.exe and setting initial memory pool and maximum memory pool on the Java tab.
