Hello, everyone. As a result, there is a failure of saving the data to the database due to a primary key conflict. The third line in the searched information lines is the synchronized NE information. The UltraEdit software makes it convenient to perform search and is recommended. Finally, search for the following error information in the extracted thread information the command word is required to delete other useless information because the thread ID is reusable.
Generally, such an error is reported when the primary keys conflict, that is, repeated data exists. Up to now, according to the log, it can be determined that the service port data that is synchronized from the UA IPMB and that is processed by the background of the NMS failed to be saved to the database due to repeated data, and as a result, the entire synchronization operation failed.
When this problem occurs, SNMP synchronization is adopted to synchronize customer data. Next, analyze the captured packet. At first, as shown in the following figure, for the node 1. In the data theatmVcCrossConnectTable of the node 1.
Therefore, all the subsequent CxC data is lost. The CxC connection ID uniquely identifies the connection relationship. The foregoing packet capture result indicates that all data behind the ID is lost.
As a result, the downlink port index related to the CxC connection ID is calculated as 0. Therefore, for each service flow, the value of DstIfIndex is unique. However, the value of this field in many records is calculated as 0 due to incorrect NE data, thereby failing to save the data to the database due to a primary key conflict. This entry belongs to an abnormal residual entry. According to the current analysis result, the synchronization failure is caused by this entry. Therefore, it is advisable to save and back up the latest configuration file, re-load the configuration file to the UA IPMB , and activate the configuration file.
A new database is re-generated when the configuration file is activated. In this way, service flows of a port cannot be queried, but the service flows are actually available on the UA IPMB. Therefore, when the OSS delivers the command of creating a service flow, an error "The Connection has existed" is reported. Matching Rule.
