1.7.2 Increasing the Number of ISH Processes

System administrators can scale an Oracle Tuxedo CORBA application by increasing the number of ISH processes on an application site, thereby enabling the ISL to load balance among more ISH processes. By default, an ISH can handle up to 10 client connections. To increase this number, pass the optional CLOPT -x mpx-factor parameter to the ISL command, specifying in mpx-factor the number of ISH client connections each ISH can handle (up to 4096), and therefore the degree of multiplexing, for the ISH. Increasing the number of ISH processes may affect application performance as the application site services more concurrent processes.

System administrators can tune other ISH options as well to scale Oracle Tuxedo applications. For more information, see the description of ISL in the File Formats, Data Descriptions, MIBs, and System Processes Reference.
