BigFix Patch provides an automated, simplified patching process that is administered from a single console.
Updates for Middleware Applications
Middleware patching is an important process for organizations to ensure their systems are secure and up to date. By applying the appropriate patches and security updates, organizations can minimize the risk of malicious attacks and potential data loss. BigFix users can enjoy unified patch management by using a single platform for deploying database and middleware patches.
Oracle Database
An Oracle Database (DB) is a collection of data treated as a unit. A database stores and retrieves related information. Oracle Database is widely used and known for its reliability, scalability, and extensive features.
Rolling back an Oracle DB patch
You can roll back most Oracle DB patches with Fixlets that HCL provides. However, rollbacks are not officially supported.

    - Configuring Oracle DB patching for your deployment
      You can configure Oracle DB patching for your deployment from BigFix console.
    - Preparing Oracle DB patch downloads
      Complete these steps to prepare for downloading Oracle DB patches.
    - Check servers for Oracle DB patch readiness by using the precheck Fixlets
      For each Oracle DB patch Fixlet a corresponding precheck Fixlet is available. The precheck Fixlets check that your Oracle DB servers are ready to accept the the specified Oracle patch level.
    - Patch Oracle databases
      Oracle Database Patch Fixlets are specific to OS, Oracle version, and specific patch level such as "OracleDB 19c on Linux - 2023-10 Patch". (There are also Patch Fixlet variants specific to ASM and RAC.) When a Patch Fixlet is deployed to a database server, it attempts to patch all the targeted databases on that server; for example, "OracleDB 19c on Linux - 2023-10 Patch" will patch all 19c databases listed in the server's oratab file to 2023-10.
    - Rolling back an Oracle DB patch
      You can roll back most Oracle DB patches with Fixlets that HCL provides. However, rollbacks are not officially supported.
    - Troubleshooting
      Troubleshooting in Oracle DB involves diagnosing and resolving issues that might arise while you work with the database server, applications, or related components.

  This topic describes how supersedence works in Patch.

Rolling back an Oracle DB patch

You can roll back most Oracle DB patches with Fixlets that HCL provides. However, rollbacks are not officially supported.

Patch rollback Fixlets remove the Fixlets that the corresponding patch Fixlet applied. For example, if an Oracle DB server is initially at the 2023-01 patch level, and the patch Fixlet for 2023-07 is applied, then the rollback Fixlet for 2023-07 removes the 2023-07 patches. After the Fixlet removes the 2023-07 patches, the DB server returns to the 2023-01 patch level.

Important: Patch rollback Fixlets do not roll back the OPatch version upgrades that a precheck patch Fixlet installed.

The corresponding precheck and patch Fixlets become applicable again after a a rollback Fixlet deployment.
