8 Behaviors

This chapter contains information on the different behaviors and workarounds for the Oracle Communications Offline Mediation Controller IMS CDF/CGF cartridge pack.

The following are the known behaviors for this cartridge pack.

  • Behavior: Editing or stopping and starting the Session Aggregation AP and the 3GPP IMS ASN.1 DC while they are processing data can result in Offline Mediation Controller generating the following warning alarm:

    Configuration; NPL originated Critical log; A record contains an incorrect value in the field/AVP Accounting-Record-Type. This record will be processed as an ACR-Stop.

    There is also the possibility of duplicate record generation.

    Work-around:

    1. Stop the Session Sequencing EP

    2. Wait for all records to propagate though the Session Aggregation AP and the 3GPP IMS ASN.1 DC (Current NARs = 0 for more than 5 seconds in the Node Performance view of the Administration window)

    3. Proceed with the stop or edit operation

    4. Save or start the node

    5. Start the Session Sequencing EP

      Note:

      If the Session Sequencing EP is stopped for a period longer than its flush timer setting, duplicate records may appear.
  • Behavior: Changing the Expiry Interval setting on the Session Sequencing EP will affect new input records only. The EP will still flush any records waiting to be sequenced according to the pre-configured setting.

    Work-around: Not applicable.

  • Behavior: When the Diameter CC constructs the ACA (Accounting-Answer) in response to the ACR (Accounting-Request) the values for Origin-Host and Origin-Realm are obtained from the values in the ACR and therefore do not uniquely identify the CDF/CGF host.

    Work-around: None.

  • Behavior: According to the 3G Technical Specification, the GPRS-Charging-Id field is declared as type INTEGER and therefore the CCF requires that the associated Diameter AVP (GPRS-Charging-Id) contain an integer and not a string - otherwise the node will skip the field and raise the following warning alarm:

    Configuration; Error occurred in NPL; Exception occurred in the NPL assignment statement on line 150. Exception is java.lang.ClassCastException: For input string: "GPRS #1" NPL execution continuing with next statement.
