JWS Forms Fail on Secondary EBS Application Nodes

Customer May 3, 2020 at 11:34 am

We have a multi-node EBS application tier with JWS enabled. If the connection hits Node 2 or Node 3 directly, Forms fail to launch. However, if the master node (Node 1) is running and handles the connection, everything works fine. We already ran AutoConfig on all nodes. What specific configuration should be checked for multi-node JWS setup?

  This issue points to a configuration discrepancy between your nodes, likely related to hostname registration or the Forms Launcher profile . You must first inspect the value of the `ICX: Forms Launcher` system profile to ensure it is correctly pointing to your load balancer or the designated access URL, not an individual node’s internal address . Secondly, run a SQL query against the `apps.fnd_nodes` table .

  What details should I be looking for when querying the `apps.fnd_nodes` table?

  You should examine the output of the query `select support_db D, support_cp C, support_admin A, support_forms F, support_web W, node_name, webhost from apps.fnd_nodes order by node_id` . Pay close attention to the `webhost` column and the `support_forms` column (labeled ‘F’) . Ensure that the `webhost` reflects the publicly accessible address (Load Balancer or hostname) and that the `support_forms` flag is correctly set for all nodes intended to serve JWS forms .

  We had the old Look and Feel (SWAN/SKYROS) applied before migration. After JWS, it defaulted to the modern Alta Look and Feel. Can we revert the UI style?

  Unfortunately, Oracle no longer supports the Look and Feel options of previous releases after applying critical ATG patches (like R12.ATG_PF.C.Delta.5 and higher) . If your UIX version upgraded to 12.2.6 or later during the JWS migration, Oracle only supports the ‘Alta Look and Feel’ with Java Web Start . Customization to revert to SWAN or SKYROS is not supported .

  Where is the `javaws` executable located that is required to open the downloaded `jnlp` file?
- Support May 11, 2020 at 10:40 pm
  When a JNLP file is downloaded (e.g., when launching a form menu), the user may be prompted on the first run to provide the path to the `javaws` executable . Its precise location can vary depending on the operating system and installation structure . Users should locate the `javaws` binary within their client-tier JRE installation path to correctly associate the JNLP file , .
