d. Set the message compression and transaction parameters for the connection:
Property Description
Enable
Compression
Custom
Compression
Factory
Default Txn
Batch Size
Client
Transaction
Buffer Size
Max number of
redeliveries
When selected, requires connections that use this connection factory to
perform message compression before sending messages, and requires the
broker to deliver compressed messages to connections that use this
connection factory. The setting could be overridden by the client.
Specifies the custom class that defines message compression and
decompression.
Specifies an integer value for the common batch size. During a
transaction, messages can be batched on the client for later submission
when the transaction is committed or whenever the batch size or the
session’s ability to maintain the integrity of the transaction is at risk.
Messages are batched for each destination within a session. When several
destinations are used in a single transaction, messages are batched for
each destination separately. (For more information, see the
“Transactions” chapter in the Progress SonicMQ Performance Tuning Guide.)
Specifies the size, in bytes, that the client runtime is willing to buffer per
transaction. If the buffer size is reached, JMS client sending threads will
block until further messages are saved by the broker. The broker will
apply a transaction buffer size that is the lesser of the client-specified
value and the broker’s Transactions: Buffer Size (which has a default
setting of 32768). The default value is 0, which means that the broker’s
Transactions: Buffer Size is applied.
Specifies the number of attempts at redelivery that are allowed.
8. After you configure the parameters, click Apply.
