To define error codes that indicate that the back-end database with
which the data source communicates is no longer accessible:
If you have not already done so, in the Change Center of the Administration Console, click Lock & Edit (see Use the Change Center).
In the
Domain Structure tree, expand
Services, then select Data
Sources.
On the
Summary of Data Sources page, click the data
source name.
Select the
Configuration: Connection Pool tab.
Scroll down and
click Advanced to show the advanced connection
pool options.
In Fatal Error Codes, enter a
comma-separated list of error codes that are treated as fatal errors
to prevent a connection from being put back in the connection
pool.
Click Save.
To activate these changes, in the Change Center of the Administration Console, click Activate Changes. Not all changes take effect immediately—some require a restart (see Use the Change Center).
