The maximum number of messages that can be sent through a channel before taking a checkpoint.
For considerations when choosing the number for batch size, see the description of the Batch size (BATCHSZ) property in the WebSphere MQ Intercommunication book.
Required | No |
Data type | Integer |
Default | 50 |
Range | 1 through 9999 |
The maximum message length, in bytes, that can be transmitted on any channel for the WebSphere MQ link. This is compared with the value for the partner and the actual maximum used is the lower of the two values.
For considerations when choosing the number for message size, see the description of the Maximum message length (MAXMSGL) property in the WebSphere MQ Intercommunication book.
Required | No |
Data type | Integer |
Default | 4194304 bytes (4MB) |
Range | 0 through 104857600 0 indicates to use the largest value that the target queue manager will honour. |
The time, in seconds, between heartbeat flows passed from the sender channel across the WebSphere MQ link when there are no messages on the transmission queue.
Heartbeats give the receiving channel the opportunity to quiesce the channel connection.
For considerations when choosing the number for this property, see the WebSphere MQ Intercommunication book.
