Symptom

  • You are running a SAP Business Suite application on SAP ASE and you have configured a High Aavailability Disaster Revovery (HADR) environment with SRS
  • You run sap_status path command to check the health and latency status of the replication paths in the HADR system and find that Latency Time shows the timestamp many days ago

1> sap_status path
2> go
