SUPPORT / SAMPLES & SAS NOTES
Problem Note 49604: Too many connections are made to the Netezza database and these connections are not being dropped or reused when no longer needed
 |  |  |  |  |
SAS/ACCESS® Interface to Netezza generates too many connections to Netezza, especially when constructing query nodes in SAS® Enterprise Guide®. The Netezza connections are not released until SAS terminates. As a result, users might run out of available connections and the Netezza database might become inaccessible to other systems or users.
The following error message might occur when you use CONNECTION=UNIQUE (default setting), if you have exceeded the connection limit that is set on the Netezza database.
[Error] CLI error trying to establish connection: The permitted number of client connections(510) has been exceeded
