11.2.10. Defining the Switchover Delay Previous topic Parent topic Child topic Next topic

If a breakdown has been detected in the OpenScape 4000 host system or the IP network, and if a CC-IP has decided based on its configured rules that access points/OpenScape 4000 SoftGates should be switched over, there is another point to be considered:
How should the overall system react if the OpenScape 4000 host system carries out a RELOAD?
There are two possibilities:
  1. React as quickly as possible, i.e. perform immediate switchover. In the case of a RELOAD, switchover to emergency operation is then always performed.
  2. Delay the switchover long enough to prevent a RELOAD leading to emergency operation.
In line with this decision, you must set the AP Emergency switchover delay either
  1. to zero (switch immediately) or
    • to the length of time that the OpenScape 4000 system needs to execute a complete RELOAD.

    CHANGE-SIPCO:TYPE=TIMING,APESWDLY=5;
    Sets the switchover delay to 5 minutes ->i.e. the system RELOAD takes 5 minutes; wait for the corresponding length of time.
    The modified data does not take effect until after you have used OpenScape 4000 Assistant Backup & Restore to copy the database to the CC-AP/Survivable OpenScape 4000 SoftGate, and the CC-AP/Survivable OpenScape 4000 SoftGate has accepted it.

    APE Umschalteverzögerung
    Das Umschalten eines Access Points/OpenScape 4000 SoftGates in den Emergency Mode kann um eine konfigurierbare Zeit verzögert werden.
    Der Wert wird in Minuten angegeben.
    Wertebereich [0 .. 99].
    "0" sollte nicht konfiguriert werden, weil damit würde der APE auch im Falle eines RMX Restarts des Hostsystems (CCA/CCB) übernehmen.
    Konfigurationsempfehlung und AMO Defaultwert: 5 (Minuten)

    APE Switch Over Delay
    The switch-over of an Access Point/OpenScape 4000 SoftGate to Emergency Mode can be delayed for a configurable amount of time.
    The value is entered in minutes.
    Range [0 .. 99].
    "0" should not be configured because then a switch over to the APE is performed even in case of a restart of the RMX of the host system (CCA/CCB).
    Recommendation configuration and AMO default: 5 (minutes)
