Overview
This plug-in provides a Smart Service and Function for executing stored procedures. The Smart Service can be used to execute stored procedures that modify data. Result sets are returned as CDTs. As custom functions cannot have side-effects, it must not be used to execute stored procedures that modify data. It is only safe to use the Smart Service with stored procedures that modify data. Following SQL Statements should not be used by the stored procedures executed with the function:
Key Features & Functionality
Hi James,
I have a query on how connection is maintained while using the function as well as smart service, i.e. when does the connection to DB opens and closes?
Is it per execution of smart service / function call or some other logic?
We are calling a stored procedure hosted on another legacy system data base using this plugin and they have reported that there are many open connections on their dashboard for this call from Appian. Any comments or suggestions welcomed:)
Thanks.
Hitesh
Each execution of the smart service or function requests a connection from the pool and returns it to the pool when complete. A high volume of concurrent connections (using this plug-in or other database related functionality in Appian) may result in additional connections being made to the database.
The connection pool behaviour is not specific to this plug-in. If you require further input please reach out to Appian Technical Support.
