[. . . ] Setting this parameter to a lower value refreshes any data cached in the real-time service more often. High traffic behavior Use the Queuing timeout parameter to specify the maximum amount of time the client application must wait for a request to be processed. If the number of requests the Access Server receives for a particular service exceeds the number of registered service providers that can process those requests, the Access Server queues the requests in the order they are received. When a service provider completes processing a request and responds to the Access Server, the Access Server dispatches the next request in the queue for that service to the open service provider. If there are many requests and the queue causes requests to exceed the queuing timeout, the Access Server removes the oldest request from the queue and responds to the client with an error indicating that the request failed. You can use the queueing timeout to ensure that the client receives a timely response, even during high-traffic periods. The queuing timeout is in seconds. 100 Data Integrator Management Console: Administrator Guide Real-Time Performance Service statistics 8 A service experiences high traffic when the available resources cannot process the received requests efficiently. High traffic occurs when the time messages wait to be processed exceeds the time required to process them. See "Using statistics and service parameters" on page 104. Response time controls Use two parameters to configure how long the Access Server waits for responses from service providers for a particular service: · · Processing timeout Processing retry count max After the Access Server sends a request to a service provider to process, the Access Server waits for the response. If the response does not arrive within the specified processing timeout, the Access Server sends the request to another waiting service provider. If the first attempt fails, the Access Server will attempt to process the request as many times as you specify in the Processing retry count max parameter. If Processing retry count max is set to zero, the maximum response time is equal to the queuing timeout plus the processing timeout. Service statistics The Real-time Service Status page for a particular service shows overall statistics. · Number of processed requests Data Integrator Management Console: Administrator Guide 101 8 Real-Time Performance Service statistics The number of requests for this service from any client that the Access Server received and responded to since the last time the Access Server started. · Number of requests in the queue The number of messages the Access Server has received from a client for this service but has not sent to a service provider for processing. This value reflects the current state of the Access Server. · Max queuing time (milliseconds) The maximum time any request for this service waited after the Access Server received the message and before the Access Server sent the request to a service provider for processing. · Average queuing time (milliseconds) The average time that requests for this service waited after the Access Server received the request and before the Access Server sent the request to a service provider for processing. · Queuing timeouts The number of requests to which the Access Server replied to the client with an error indicating that there was no service provider available to process the request. · Max processing time (milliseconds) The maximum time required to process a request for this service. It is the difference between the time the Access Server sent the request to a service provider and the time that the Access Server responded to the client. The processing time does not include time the request spent in a queue waiting to be sent to a service provider. · Average processing time (milliseconds) The average time required to process a request for this service. It is the difference between the time the Access Server sent the request to a service provider and the time that the Access Server responded to the client. The processing time does not include time the request spent in a queue waiting to be sent to a service provider. · Processing timeouts The number of requests that the Access Server sent to a service provider and did not receive a response before exceeding the processing timeout. These requests are either successfully processed by another service provider, or if they are left unprocessed beyond the time indicated by the queuing timeout parameter, the Access Server returns an error to the client. 102 Data Integrator Management Console: Administrator Guide Real-Time Performance Service provider statistics 8 Service provider statistics The Service Provider Status page shows the statistics for an instance of a real-time service. When Data Integrator measures a statistic "from the start, " the value does not restart when the Access Server restarts the service provider. The value restarts when the Access Server restarts. When Data Integrator measures a statistic "for the current service provider, " the value restarts when the Access Server restarts the service provider, either due to error or when the service provider reaches the maximum number of requests defined for the service. · Max processing time (milliseconds) The longest time it took between when the Access Server sent a message to this service provider and when the service provider returned a response. · Average processing time (milliseconds) The average time it took between when the Access Server sent a message to this service provider and when the service provider returned a response. If you are running more than one service provider for this service, compare this statistic with the same statistic from the other instances. If this instance is significantly different, look for processing constraints on the computer where this instance runs. · Processed requests (for the current service provider) The number of requests that the Access Server sent to this service provider to which the service provider responded. · Processed requests (since start) The number of requests that the Access Server sent to this service provider to which the service provider responded. · Error replies received from the start The number of requests that the Access Server sent to this service provider to which the service provider responded with an error. · Communication errors encountered from the start The number times that the communication link between the Access Server and this service provider failed. · Timeout errors encountered from the start Data Integrator Management Console: Administrator Guide 103 8 Real-Time Performance Using statistics and service parameters The number of times the Access Server sent requests to this service provider and did not receive a response within the time specified by the processing timeout. · Service provider connections (restarts) from the start The number of times the Access Server restarted this service provider when it did not receive a response from the service provider. · The last time of a successful flow launch The system time when the Access Server last started the real-time service associated with this service provider. If the Access Server never successfully started an instance of this service provider, the value is "N/A. " This time is from the computer running the Access Server. · Time since start attempt The amount of time since the Access Server last attempted to start this service provider. [. . . ] Make sure that the real-time jobs are available in the repository associated with the Job Server. Make sure the repository and the Access Server are connected to the Administrator and that the repository is available. If you change the password for your repository database, the job server will not be able to start real-time services. To fix this problem, re-register your repository in the Administrator and reconfigure the real-time services. · Real-time service cannot register with Access Server If this error occurs, you would see: · · · A red indicator for the service provider An error log in the Logs-Current page (the startup timeout will eventually be triggered) An error log available from the Service Provider Status page. Make sure the Access Server host name correctly identifies the computer where the Access Server is running. 196 Data Integrator Management Console: Administrator Guide Troubleshooting Restarting the Access Server 14 · Access Server cannot connect back to application client If this error occurs, you would see an error log under the Access Server's Logs-Current node.
