  1. Create a file named jms.properties inside  inside <EI_HOME>/conf with the following properties:
    • lst_t_core=200

    • lst_t_max=250

    • snd_t_core=200

    • snd_t_max=250

      Note
      titleDetermine a suitable value for lst_t_core and snd_t_core

      Make sure that the above mentioned recommended values per server satisfy the following calculation.

      Code Block
      lst_t_core >  Total number of consumers + 20
      
      lst_t_core < lst_t_max
      
      snd_t_core > Total number of consumers + 20
      
      snd_t_core < snd_t_max
        • Total number of consumers = transport.jms.MaxConcurrentConsumers * Number of JMS proxies
        • 20 threads have been added as a buffer.
        • Default value for lst_t_core and snd_t_core is 20.
        • If you do not specify a value for lst_t_core and snd_t_core, the default values are applied.
      Warning

      If the above values that you derived exceed the recommended values, make sure that your server has the necessary resources to handle the defined thread pool size efficiently.

    Create a directory called conf under your <EI_HOME> directory and save the file in this directory
