Use high-value link statistics to help diagnose MSC link problems
You can use high-value link statistics to help diagnose
certain problems that lead to a backup of messages on MSC links. In
the output of the type-2 command QUERY MSLINK command,
the fields for the high-value statistics all begin with HI.
For example, if a message backup on a link occurs, you might check for an unusually high value recorded for the Hi_SendIO_Time. An unusually high I/O time to send a message might indicate that an outage has occurred in the network connecting the two IMS systems and you can then pursue the cause.
The
high-value statistics that you can check include:
- Hi_Proc_Time
- The highest (longest) time the link was dispatched to process
- Hi_MSG_Send_SZ
- The largest message size sent (type X'01' or X'03' message record)
- Hi_QGET_Time
- The highest (longest) QMGR call (GU or DEQ) to process a send message.
- Hi_SendIO_Time
- The highest (longest) I/O time to send a message
- Hi_MSG_Rec_SZ
- The largest message size received (type X'01' or X'03' message record)
- Hi_QPUT_Time
- The highest (longest) QMGR call (ISRT or ENQ) to process a received message
- Hi_RecIO_Time
- The highest (longest) I/O time to receive a message
