You can elect whether - on each sample - the SQL Toolkit keeps the connection, or disconnects after the sample. |
By default the SQL Toolkit will establish a connection using the credentials defined in the sampler setup. Having used this connection it will return it to a pool where it will be reused next time a connection with the same credentials is required. Externally this will appear that the connection remains open between the probe and the database. There is however a setting in the SQL Toolkit called "Close connection after query" which, by default, is set to False. When this option is set to True, Geneos attempts to close the existing connection via a "disconnect" database call every time a query is completed. No connection is being reused/returned to the database connection pool, since a new connection is established (and consequently destroyed) after every query.

If you encounter the error "Fail - ORA-02391: exceeded simultaneous SESSION_PER_USER limit(2391)", this means that Geneos has no visibility over an Oracle database's SESSION_PER_USER limit. Geneos will either reuse an existing connection from the database connection or create a new one every time a query needs to be executed. To solve this, ask the database administrator to increase the SESSION_PER_USER limit of the user profile. For further details regarding the encountered error, see the links below: |
