We are using Gen8.6 with latest patches.

When I try to update an object's property I am getting error EAPI_OBJECT_PROTECTED_RC.

The model is new generated model from 8.5 version.

In documentation there is not so mach about this error, some where there is info that there could be because of a subset.

I have checked, there is no subset of the model.

Please if some one knows why the object is locked and/or how to free it.

The log of upddemo.exe is following.

I have opened a Support case for Gintaras and working to find a resolution.

It's because you've locked the model with EApiLockModel.

Per https://techdocs.broadcom.com/us/en/ca-mainframe-software/devops/ca-gen/8-6/reference/encyclopedia-api-reference/model-lock-and-unlock.html, a read lock will prevent updates, a write lock will prevent access.

@Daniel Stratton

The answer is not correct. You must lock model to be able to update objects.

Or else, you will get the error :

EAPI_MODEL_NOT_LOCKED_RC if the model is not locked for update

As per https://techdocs.broadcom.com/us/en/ca-mainframe-software/devops/ca-gen/8-6/reference/encyclopedia-api-reference/property-information/eapiupnumeric.html

Hello to all,

The bug was in my code. I was caching model ID & Object ID.

As a result I was trying to modify object from other model.

The misleading error message EAPI_OBJECT_PROTECTED_RC was not expected.

I believe the error should be EAPI_MODEL_NOT_LOCKED_RC since the other model was not locked for edit.

The correct error would lead to examine program flow and wrong model id usage would be found mach faster.

Best Regards
