High Availability Monitors Version A.03.01 Release Notes

10 Chapter1

Known Problems and Workarounds

server is a reliable indicator of the availability of its corresponding

database. (You can also use /rdbms/server/status/

systems where a single database is conﬁgured.)

When a database is not available, an error message

indicates that its resource instance is not available.

• What is the problem? If a database is unavailable or its server is

down, you may see this error message: Resource “/rdbms/...”

is not available. The message will pop up in the EMS graphical

user interface window when you try to access the following resources:

server_started, allowed_max_connects, peak_connects,

usage (for both server and database), commits,

commits_per_sec, database used, and database allocated.

• What is the workaround? Before you try to monitor these particular

resources, be sure the database is available, and its server has been

started.
