We are planning a significant infrastructure change: Upgrading an Oracle E-Business Suite server from Oracle Linux 7 to Oracle Linux 8. What are the primary technical considerations we need to address to ensure EBS compatibility post-upgrade?

    A major OS upgrade requires rigorous compatibility checks across all EBS components (Database, WebLogic, Apache, Java). You must ensure that the specific EBS version (e.g., 12.2.x) and associated database version (e.g., 19c) are fully certified and supported on Oracle Linux 8.

    How can our DBA team utilize tools for checking system parameters and environment health quickly before and after the OS upgrade?

  • Support Enginatics

    The Blitz Report DBA toolkit provides essential diagnostic reports. Before the upgrade, run AWR reports for a performance baseline , check the configuration of FND_NODES , and verify critical AD/TXK patches using AD_PATCH.IS_PATCH_APPLIED. This simplifies post-upgrade verification.

    Will the OS upgrade impact client access components like Java Web Start (JWS)? We have users running forms on Mac OS.

  • Support Enginatics

    The OS upgrade primarily affects the server side. However, you must verify that server-side Java configurations remain intact. Client-side issues, such as Launching EBS forms with Java Web Start on Mac OS , usually relate to client Java version and local JWS configuration, but server changes can affect the JNLP file generation via the `ICX: Forms Launcher` profile.

    We need to clear the EBS cache after the OS upgrade to ensure all old binaries or session data are flushed. What is the standard approach?

  • Support Enginatics

    You should use the documented procedures for clearing the Oracle EBS cache in a script. This is a necessary step in EBS R12.1 and R12.2 maintenance to ensure the application tier utilizes the newly configured server environment correctly.

    Since this is a major upgrade, we will generate many BR100s for data setup documentation.

  • Support Enginatics

    The Blitz Report Upgrade Toolkit includes specialized Support and Data Migration reports for automated BR100 extracts. These reports are invaluable for documenting configurations pre- and post-OS migration.

    We need to ensure reports generated on the Linux server are automatically transferred to a secure repository post-upgrade.

    You can continue using automation. The method of Sending files from Linux to Sharepoint online using a python script remains a viable solution for securely transferring Blitz Report Excel/PDF output from the updated Linux application server.
