Pointing Functions at Connection Pools
To point a function at a connection pool
1. In Integration Server Administrator, go to Settings > JDBC Pools.
2. In the Functional Alias Definitions area, click Edit for the function.
3. In the Associated Pool Alias field, identify the connection pool at which to point the function.
4. If the Fail-Fast Mode Enabled option is available, choose whether to enable or disable.
Transient errors caused by an unavailable database can prevent a connection pool from connecting to its database. You can configure a function to enter fail-fast mode to handle this situation. In fail fast mode, all attempts by the function to get a database connection immediately return a SQLException; this saves time by preventing retry attempts. When database connectivity is restored, the function exits fail-fast mode and returns to normal operation. Fail-fast mode can improve performance when you are using synchronous audit logging (see the ).
5. Click Save Settings.
6. In the Functional Alias Definitions area, initialize the pool by clicking Restart for the function.
7. Make sure Integration Server can connect to the database by clicking 
for the function. 8. Restart Integration Server.
