Überwacht man mit check_oracle_health den Füllgrad von Tablespaces einer Oracle-Datenbank, so werden in der Ausgabe des Plugins grundsätzlich alle Tablespaces aufgeführt. Dabei spielt es keine Rolle, ob ein Tablespace genügend freien Speicherplatz hat oder bereits zu voll ist. Dies hatte in der Vergangenheit zur Folge, daß die Ausgabe bei großen Datenbanken mit vielen Tablespaces sehr, sehr lang war und somit in der Web-Oberfläche von Nagios etwas unübersichtlich erschien. Mit den neuesten Releases von check_oracle_health, check_db2_health, check_mysql_health und check_mssql_health ist es nun möglich, nur noch diejenigen Tablespaces/Datenbanken anzeigen zu lassen, die voller sind als es die Schwellwerte erlauben.

Citrus includes a lot of convenient features which are only waiting for you to discover and use them. The other day I needed to validate a SoapAttachment. As you probably already know, a SoapAttachment is referenced by a href property in an Include tag like this: <Include href="..." xmlns="http://www.w3.org/2004/08/xop/include"/>. Validation is quite easy when you’re still mock testing your application because you have full control over what your mock response will look like.

Devoxx - Day 4

The last full conference day of the Devoxx was again packed full with very interesting talks of various kind. It started with a keynote about the roadmap of JEE 7. Summarizing we can expect some smooth refinements of the platform (exept maybe the support for virtualization out of the box). Here are our impression on the talks of Thursday. Please expect our summary blog post on monday since we are all now in rush to get out things done and to catch train, plain etc. We hope, you enjoyed the blog flood so far ;-)
