JMS Provider Service
The JMS Provider service enables you to manage the JMS destinations and connection factories on the J2EE Engine.
This service runs on both the server and dispatcher.
Each working destination (the one with at least one producer or consumer) may take up to sizeLimitInMasterQueue bytes, which means that you should ensure that N * sizeLimitInMasterQueue (where N is the number of expected working destinations) does not exceed the virtual machine heap size.

The maximum number of threads that can work simultaneously to deliver messages to the destinations. |

600000 |
clientMemorySize |
The total amount of memory the client can distribute in the buffer. |
10485760 |
clientConsumerBuffer |
The size of the buffer the client can use. |
102400 |
countLimitInMasterQueue |
The limit of the number of messages in the master queue. |
32000 |
sizeLimitInMasterQueue |
The total size of the messages in the master queue. |
1048576 |
fetchSizeOnStartupInMasterQueue |
The number of messages that are loaded at the startup of a destination. |
4096 |
maxFetchSizeInMasterQueue |
The maximum count of the loaded messages at the startup of a destination. |
1024 |
transactionStorePath |
Defines the directory with enough free space where the transactions are to be written. |
|
Dispatcher
Property |
Description |
Default Value |
/tcp |
The port on which the JMS Provider opens a socket. |
1139 |
