[OO Tip] Running flow via Load Balancer returns "502 Proxy Error"



Using Operations Orchestration (OO) and running the following "wget" via a Load Balancer (LB) returns this error:

2011-12-12 12:43:13 ERROR 502: Proxy Error.

The following "wget" command works if "oo-lb-server" is replaced by Central server's IP or hostname.

wget -t 1 --no-check-certificate --http-user=admin --http-passwd=xxxxxx 'https://oo-lb-server:8443/PAS/services/rest/run/Library/My Ops Flows/testFlow'


The cause is that OO LB uses Apache with a default timeout is 300 seconds (5 minutes).




Please add your desired timeout value in httpd.conf or pas.conf,
The default location of OO LB conf files is "%ICONCLUDE_HOME%Clusteringapacheconf"

Because OO LB does not specify TimeOut or ProxyTimeout parameter, using either TimeOut or ProxyTimeout in httpd.conf should extend the timeout.

For example, to extend the timeout to 600 seconds, use one of the following:

1. add "TimeOut 600" in httpd.conf

2. add "ProxyTimeout 600" in httpd.conf

3. add "TimeOut 600" in <VirtualHost *:8443> in pas.conf

4. add "ProxyTimeout 600" in <VirtualHost *:8443> in pas.conf

Note that modifying pas.conf also extends the timeout, however, if cluster-config.jar is used to modify the LB node, the change might be overwritten.
