Portal service is intermittent (/irj/portal)

[Former Member]

Hi All

We have a strange issue in our production portal

We have CI+DB running in ngepha-pub and application servers running on

Ngsvawrk162 & ngsvawrk165, load balancing is happening via web

dispatcher.

From 9th of April the portal service is intermittent, like we are

getting u2018u2019page not displayedu2019u2019 error message, after refreshing it goes

through

Observed that one of the application server is faulty and causing the

intermittent issues, if we shutdown application on ngsvawrk165, we

donu2019t have any issues in load

Balancing via web dispatcher, can you guys please provide help to

resolve this issue?

And I have installed Httpwatch software and observed that we are

getting error

u2018u2019401 Unauthorizedu2019u2019 as of now we shutdown the faulty application, but

potentially will be having high user loads cause the performance

problem with one application is down.

Please provide some inputs

Regards

Hi,

I would remove the 165 server from the load balancing configuration so that it does not use it for now. Then start the 165 server and call it directly... what response do you get? Check the default.trc files on the 165 server for any errors. If the 165 server is just a dialog instance (i.e. not the CI) then you can delete it and recreate it... that might be the easiest fix if the problem is not evident to you in the logs.

BRgds,
