Multiple instances of TAC on same host

Anonymous — Sat, 16 Nov 2024 10:07:17 GMT

Can I install TAC for talend 6.2.1 on the same host where we already have 5.6 TAC installed? We need to have both TACs up and running at the same time for multi stage migration.

No, you would have a port conflict. While you could modify the 6.2.1 TAC configuration to use a different set of ports to avoid such conflicts, I would recommend simply installing it on a separate server to minimize complexity and change for errors.

I was able to install 6.2 on separate ports and now I am getting the following error on the old TAC. Please see the log below.

I assume that each TAC is hopefully pointint at its own database. The error is probably due to the browser caching the result from the previous login. Try using Chrome incognito mode with one TAC and regular chrome or another browser for the other TAC.

I reinstalled TAC under TAC621 instead of TAC and it is working fine now. Thanks for your suggestion.
