Top Three EBS 12.2 Online Patching Resources

Steven Chan
Senior Director

Oracle E-Business Suite Release 12.2 introduced Online Patching, a feature that greatly reduces the downtime that was needed in previous releases to apply patches and updates. Online Patching minimizes downtime by allowing patching operations to be performed while users remain on the system.

Online Patching features

  • In Release 12.2, all patching operations are carried out while the applications are in use and users are online. 
  • Patching is performed using the new adop (AD Online Patching) utility.
  • A short period of downtime is required to restart application tier services; the E-Business Suite database does not need to be restarted.

    I want to know about a scenario. I have applied patch/es using adop. Before cutover, can I start patch base services using forcepatchfs option to check impacts of patch on application and do UAT?

    If yes then apache port is same for both the file system. So how apache service will start? Will it use any different port?

    The two file systems in EBS 12.2 are used only for online patching. You cannot perform system testing in the second file system. As with earlier EBS releases, you must test patches in a separate pre-production environment before applying them to your production environment.
