We do a heartbeat at fixed intervals ... a heartbeat consists of 1. logging in 2. inserting sysdate into a table. 3. sleeping for 3 seconds. 4. performing current_sysdate-sysdate_from_table 5. rollback 6. exit with output from step 4.
If the output from step 4 is excessive (> 5 or 6 seconds), DBAs, Unix Admins automatically get paged. This gives a check for instance, listener too. Some might think it is a bit over the top, but we like it.
