How to redeploy a web app

For certain classes of errors, the solution is to redeploy the affected web app. For instance, the TDS web app can hold on to a stale database handle when Ingres is restarted without its knowledge. In that case, TDS needs to be redeployed.

Production

  1. Log in to the Weblogic admin console http://bay:7001/console
  2. Navigate to Domain Configurations > Your deployed resources > Web application modules
  3. Click on the affected web app (for instance, TPW)
  4. Click on the Deploy tab
  5. Click on the Redeploy button and wait about 10-15 seconds
  6. Watch for the Deployment Status to return to Available.
    1. if it does not become Available after 30 seconds try to cancel and Deploy
    2. if it still does not become Available after another 30 seconds, restart the Weblogic service
