Multiple Instances on Same Machine as Oracle HTTP Server

Multiple JVM Support and Load Balancing


5.2 Multiple Instances on Same Machine as Oracle HTTP

To configure multiple JVM instances on the same machine:


Modify the jserv.conf file so the Oracle HTTP Server is aware of the multiple
JServ instances that are running. Start each of these JServ instances manually.
Insert the following statements after any existing statements in the section that
begins with <IFModule> and ends with </IFModule> in the jserv.conf file. The

file is in the ORACLE_HOME\Apache\JServ\conf directory.


Modify the following:

<IfModule mod_jserv.c>

Running multiple instances of JServ requires a manual start for each

ApJServMount /ptg balance://set1/root


W1, W2,...WN are integers that determine the load-balancing weight
assigned to each of the instances. To balance equally among all instances; do
not specify Wx; the weight value must be an integer. Weight can be decided
on the relative load you want each JServ to handle. Requests for /ptg are
load-balanced on set "set1":

ApJServBalance set1 PC1 W1

ApJServBalance set1 PC2 W2



ApJServBalance set1 PCN WN


Port numbers can be any valid port on the system, however they should not
conflict with any other application using the same port.
