Recently, a widespread issue has been affecting Oracle Exadata Administrators, particularly those attempting to upgrade their Grid Infrastructure to 23. Consequently, the failed upgrade leads to an unfamiliar error message being thrown, pointing to a problem with resource dependencies.

More often than not, when dealing with complex technical issues such as these, getting a grasp of the root cause can be quite a challenge. As it turns out, this specific issue can be boiled down to a malfunctioning delete operation during the removal of the previous release’s version. This process failure, however, does throw an error code yet is documented in the official Oracle Support document Doc ID 2986989.1, detailing the steps required to diagnose and resolve issues during Grid Infrastructure upgrades.

Delving deeper into this problem, we need to identify the triggers. Essentially, this situation arises when the Oracle Grid Infrastructure resource dependencies for a particular node get deleted, however, not all dependencies associated with it get completely removed. As a result, once the upgrade process fails, there persists a partial leftover in the OLR (Oracle Local Repository) that would need to be re-run.

Fortunately, to surmount this challenge, we can follow some steps and clean-up actions. Initially, the user is required to complete manual resource deletion, making sure that they apply these actions to each affected node separately. Further, reconfigure resource dependencies if needed, taking great care to execute ” grid -configuration” command to proceed – while performing additional validation on other operations that involve editing / initializing the Oracle Grid Infrastructure resource dependencies that go without saying would otherwise become non functional. This detailed process might call for an extra round of caution and verification checks, especially given the specifics involved when cleaning and readjusting resource dependencies into an unproblematic coherent configuration following grid reconfiguration failure. More details can be seen at the end of this article.

Understanding Grid Infrastructure Upgrade Process Error in Oracle Exadata

In a real-life scenario, to mitigate risks related to partial upgrades or removing former storage mounts, you could adopt practices similar to monitoring those failed state upgrades at hand (like in the upgrade operation run via `grid -configuration`) and make the most of diagnostic log review for your ongoing proactive interventions.

How to Fix a Failed Upgrade and Diagnose Resource Dependencies Issue in Oracle Grid Infrastructure

As indicated before, some additional measures must be applied to fix these upgrade issues while troubleshooting error messages shown on screen in reaction to previous install /update invocations while attempting the current upgrade over there. Finally, you end up getting your environment fixed after getting hold of the relevant log output information saved for knowledge in oracle database enterprise manager as well as for the subsequent cleanups.

Illustrative Steps to Address and Solve a Resource Dependencies Issue in Oracle Grid Infrastructure with a focus on the

upgrade failure with unresolved partial state

Step 1: Clean Up Incomplete Actions and Run Administrative Operations Again

When we encounter a problem of failed upgrade, we need to address it on each individual node involved in the upgrade. Specifically, we need to make sure we have done:

• clean-up any actions previously underway
• remove any former versions of release properly and associated additional storage mounts
• reactivate the prior resource dependencies that might have been initialized

Step 2: Remove Orphaned Entries on Individual Nodes Manually if Needed and Review Diagnostic Logs

Following a removal process as proposed in Oracle Database 23 Documentation, we must deal with resource dependencies if they haven’t been successfully deleted by running once again related and customized “remove resource” procedure to handle situations that lead to failure:

Step 3: Monitoring failed state and log diagnostic messages from Pre-upgrade Execution of grid -p and grid-configuration while identifying residual cleanup that needs re-checking

Make sure that “grid-configuration” and diagnostics have covered both Grid Infrastructure nodes and operations cleanup; especially have diagnostics running based on prior upgrade failure. Always ensure a good clean-up cycle for all operations diagnostics because diagnostics run on both the preoperational node and primary failed state as previously suggested in step two.

Summarizing

Dealing with a Grid Infrastructure upgrade failure as met in a certain version 23 can be resolved by looking at prior actions/operations alongside resources existing around this version.

Solution services like those found at www.person-it.com might offer the guidance or tools needed to implement these clean up steps and the overall environment upgrade validation procedures specified for each grid infrastructure version, to prevent mistakes that would otherwise cause disruptions or data loss.

Further Steps for a Smoother Exadata Grid Infrastructure Upgrade Process

At all costs, verify and repeat if necessary each possible measure to avert human error potentially triggered either by incomplete failure recovery steps or from the current practice. A critical reminder at every process interruption level of “grid-configuration” run during your troubleshooting endeavor – but especially during earlier preoperational node setup operation.

As it has been demonstrated, an Exadata Grid Infrastructure upgrade failure issues can be resolved in three clean and manageable steps, regardless of the Oracle database version you’re using.
