The Auto-Delete Dead Links feature can detect and remove dead links in UBIK®. If enabled, the feature deletes unreachable links automatically when encountered.
Contents
What is a Dead Link?
Dead links are Guid property values without corresponding objects, with the consequence that a lot of time is spent looking up the non-existent object in the database when reading the property value as a UBIK® object is attempted. A couple of such Dead Links can slow down a UBIK® web service, Studio or Enterprise Service drastically, therefore they should be avoided or at least cleaned up as soon as possible.
How to deal with Dead Links
- First of all, UBIK® logs each encounter with a Dead Link (but only up to once per minute) as a warning including all relevant details like the owner ID, the property name and the faulty value.
- One can enable the auto-deletion of Dead Links in the System Settings. Then, in addition to writing a log entry, UBIK® deletes a faulty value when it is encountered.
- There is the possibility to actively find and delete dead links for all instances of a MetaClass. If you know that there are Dead Links, you can do a bulk clean-up that way.
The auto-deletion is not enabled by default because there can be use-cases where the data is legitimate but other issues lead to a failure to find the object. E.g., timing issues during import or missing plugin DLLs in a setup.
Enable Auto-Deletion of Dead Links in the System Settings
- In UBIK Studio, navigate to System Settings.
- Locate the setting Auto-Delete Dead Links.
- Toggle the setting to enable or disable the feature.
Actively delete Dead Links for a MetaClass
This can be done from Who-Bert or custom code, or even via the UBIK® Enterprise Service.
UBIKEnvironment environment = anyObject.Environment;
environment.UBIKDataFactory().CleanDeadLinks(metaClassWithDeadLinks);
