ORA-03113 and ORA-02063 when using dblinks

Hi,

I have created an application which monitor's various databases in APEX (4.1).

When i query those databases i use synonyms to database links.
Becuase every now and then the target databases are going down (DEV and UAT environments) i created a check for the availability of the database links. The pl/sql procedure sets available = "yes" or "no" in  table, and this information will be used to show the available databases on the Apex page. This procedure run's every minute. Under normal circumstances only the available database's will be used in the apex pages.

However, when one of the target databases has been down, i receive ORA-03113 and ORA-02063 error's the soon as i try to log on to Apex.

Howdy, Stranger!
