Recovery

  1. ITUN PDU is allocated to each ITUN message that arrives at an MP and is de-allocated when message processing completes. This measurement is useful for evaluating whether persistent network problems exist. In general PDU buffers are engineered for required SS7 domains and the processing capacity of the MP. If network problems exist, delaying the off-loading of egress messages from the MP, then PDUs/messages will sit in internal SS7 queues. Under normal circumstances, the PDU Buffer Pool should never be 100% utilized.
  2. If this measurement is greater than zero, then a network (IP or SS7) problem may exist or an MP-specific software problem may exist (e.g., a buffer pool leak).
  3. If the problem persists, it is recommended to contact My Oracle Support (MOS).
