Would be nice to see, we occasionally have problems with bouncing a database 
which sometimes doesn't come back up fully...ie service is up but unable return 
a query from the database.

Additionally, not lists originally but you could do a simple TCP 1433/3306/ect 
port-check to the database servers...not monitoring the "service" per-say but 
monitoring a behavior of the service.

Subject: [SA-list] Database check changes

Currently in SA there are several ways to check a database
  * in SA via the SQL checker (using the old DMO libs)
  * in SA via the Oracle checker (using the Oracle Windows libs)
  * external COM check for SQL (2005/2008) using the current SMO libs
  * external COM check for ODBC
  * external COM mySQL

We are thinking about converting this to 1 type of db check that is based on 
the "native" client (for Oracle - SQL - Sybase - DB2 - Interbase - SQLBase - 
mySQL - SQLite - Postgress or ODBC).  This would require that you changing your 
existing db checks (the COM ones would still work, the internal not) and that 
instead of "just" checking if a database is online (like the current SQL and 
Oracle check do) we would do execute a SQL statement just as we do in the ODBC 
checker.
The idea is to remove the current MS-SQL and Oracle check from SA and replace 
it by the above check, other option would be to leave the old checks in it and 
create a new check (internal or as COM check)

I would like some reactions/feedback on this idea....
