A proxy server is a computer system or an application that acts as an intermediary for
requests from clients seeking resources from other servers. Configure the IBM® Spectrum Symphony client to send workload
outbound to the multicluster proxy
cluster using a proxy server.
Procedure
-
Create a configuration file, called proxy.conf, with the proxy server
(multicluster proxy
cluster's) host name and the following port numbers for the multicluster proxy cluster:
- The listening port for VEMKD, as defined in the EGO_KD_PORT environment variable within the
ego.conf file.
- The session director (SD) ports for SD SDK and SD administration, as defined in the SD_SDK_PORT
and SD_ADMIN_PORT environment variables within the sd.xml file.
- The session manager (SSM) ports for SSM SDK and SSM SIM, as defined in the SSM_SDK_ADDR and
SSM_SIM_ADDR environment variable in the sd.xml file.
For example, with the following configuration in the
proxy.conf file,
IBM Spectrum Symphony packages are sent
to the proxy server (
proxyHost
) instead of to the
IBM Spectrum Symphony host
(
symHost1
):
#VEMKD
proxyHost:7870 symHost1:7870
#SD
proxyHost:7874 symHost1:7874
proxyHost:7875 symHost1:7875
#SSM
proxyHost:31000-32000 symHost1:31000-32000
proxyHost:32001-33000 symHost1:32001-33000
Note that the lines prefixed with a #
symbol are comments for informational
purposes only. If you include comment, add them on a separate line.
-
Copy your proxy.conf file to the conf directory on
the IBM Spectrum Symphony client.
-
Configure the ego.conf file for the IBM Spectrum Symphony client to include the
IBM Spectrum Symphony host (in our
example,
symHost1
) as the value for the EGO_MASTER_LIST environment variable, and
its VEMKD port number for the EGO_KD_PORT environment variable. For example:
#EGO primary candidate host
EGO_MASTER_LIST=symHost1
#EGO VEMKD daemon port number
EGO_KD_PORT=7870
What to do next
If IBM Spectrum Symphony cannot find
the proxy server information in proxy.conf, it sends network packages to the
IBM Spectrum Symphony cluster hosts
directly. No error is reported.
If you require disabling the proxy server, remove the proxy.conf file from
the conf directory on the IBM Spectrum Symphony client.
