Connector Service
The Connector Container Service manages the overall connectivity to back-end resource systems.
The monitoring group contains the following important monitors that are activated by default:
● TimedOutConnectionRequests
Description of monitor |
The aggregated number of getConnection() requests that have failed because there was no free connection in the pool. |
Description of possible problems and their impact |
If the value is greater than 1 or the monitor value has increased recently, it means that the connection pool settings of the corresponding resource adapter are not adequate for the current user load or there is a connection leak. As a result, the connection pool is getting slower or does not respond at all. |
Boundary conditions for the metric (thresholds) |
We recommend you set the following: GY 1 YR 2147483647 RY 2147483647 YG 1 |
Recommended procedure if a problem occurs |
You can find detailed steps about how to proceed in case of timed out getConnection() requests in SAP Note 719778. |
· Maximum connections number
Description of monitor |
The maximum number of managed connections that could be managed by the pool. |
Description of possible problems and their impact |
Does not indicate a problem. |
Boundary conditions for the metric (thresholds) |
We recommend you set the following: GY 2147483646 YR 2147483647 RY 2147483647 YG 2147483646 |
Recommended procedure if a problem occurs |
Does not indicate a problem. |
· Used managed connections number
Description of monitor |
Returns the number of connections acquired by the applications and the J2EE Engine itself. |
Description of possible problems and their impact |
If Used managed connections number is close to Maximum connections number for a long time, It means that the pooling settings of this resource adapter are not correct or there is a connection leak. |
Boundary conditions for the metric (thresholds) |
We recommend you set the following: GY 2147483646 YR 2147483647 RY 2147483647 YG 2147483646 |
Recommended procedure if a problem occurs |
If the pool settings are correct, see SAP Note 719778. |
· Waiting for connections number
Description of monitor |
The number of getConnection() requests that are currently waiting for a managed connection. This happens when the pool maximum size is reached and there are no free connections in it. |
Description of possible problems and their impact |
This monitor does not indicate direct problems. It can indicate only warnings. If the value is greater than Maximum connections number, it means that the pooling properties of this resource adapter are not adequate for the current user load or there is a connection leak. |
Boundary conditions for the metric (thresholds) |
We recommend you set the following: GY 2147483646 YR 2147483647 RY 2147483647 YG 2147483646 |
Recommended procedure if a problem occurs |
If the pool settings are correct, see SAP Note 719778. |
