Measures reported by BBSysSrpTest

Server Routing Protocol (SRP) is a unique identifier used to communicate and authenticate the BlackBerry Enterprise Server with the BlackBerry relay. The BlackBerry relay is a key component of the BlackBerry system. It receives messages from within a corporate network, translates the messages, and routes them to the wireless network for delivery to the handheld device. In order to facilitate this transaction, the BlackBerry Enterprise Server maintains a constant connection with the SRP host, so that it knows where the handheld devices are located. This test monitors the SRP host and reports the status of the BES server's connections with the SRP host.  The measures made by this test are as follows:

Measurement Description Measurement Unit Interpretation
Connection_to_srp Indicates whether BES is currently connected to the SRP host or not Boolean The value 1 indicates that BES is connected to the SRP host. The value 0 indicates that BES is not connected to the SRP host. If the BES-SRP host connection fails, it would result in crucial lapses in delivery of messages to handheld devices. Therefore, if the value of this measure is 0, you are advised to perform additional prognosis to identify the cause of the connection failure, and attend to the cause quickly.
Reconnection_success_srp Indicates the number of times the blackberry server has successfully reconnected to the SRP host during the last measurement period. Number The BlackBerry Enterprise Server may disconnect the Server Routing Protocol (SRP) connection to the BlackBerry Infrastructure. This disconnection may be due to the following network conditions:
  • Packet loss
  • Latency
  • Other symptoms of poor network conditions

Immediately following the SRP disconnection, the BlackBerry Enterprise Server attempts to reconnect to the BlackBerry Infrastructure. However, if poor network conditions persist during this time, the SRP connection may be repeatedly disconnected and reconnected by the BlackBerry Enterprise Server. This is what a high value of the Failed reconnections to SRP host measure would typically imply.
Reconnection_failed_srp Indicates the number of times the blackberry server has failed to reconnect to the SRP host during the last measurement period. Number
Not_connected_to_srp Indicates the number of seconds for which BES has not been connected to the SRP host during the last measurement period. Secs If the BES remains disconnected from the SRP host for too long a time, it would disrupt the interaction between BES and the BlackBerry handheld devices within a wireless network. Such disconnections could be caused due to any of the following practical reasons:
  • Pathetic network conditions causing reconnections to SRP hosts to fail repeatedly
  • The BlackBerry Infrastructure is configured to disable SRP identification (IDs) that establish and exceed five connections within one minute. This configuration can be changed.
  • If the BlackBerry Enterprise Server is connected to the BlackBerry Infrastructure and another client attempts to connect using the same SRP ID and Authentication Key, the BlackBerry Infrastructure drops the connection to the BlackBerry Enterprise Server.
Improper configuration of BES can also affect the BES-SRP host connectivity. Such configuration issues include:
  • Firewall configurations disallowing BES - SRP host connections
  • The Network Access Node key is set to an IP address or NetBIOS name other than localhost.
  • The Server Routing Protocol (SRP) Address is blank or set to local host.
  • The SRP identifier or SRP authentication key are specified incorrectly.
  • On the Server tab of BlackBerry Server Configuration, the router host is not set to localhost.
  • The BlackBerry Router service cannot start.
