Backups failing in Oracle geodatabase

[TCEQGIS_Team]

Our backups have started failing in our Oracle geodatabase. Below is what we are seeing in the logs. Does anyone know of a solution or can provide any suggestions? 

Error in expdp log:

Can you check the "PARAMETERS" and "DOMIDX_OPSTATUS" of the index in Oracle?

select * from all_indexes Where index_name like 'A784_IX1'‍;‍

If PARAMETERS is blank or DOMIDX_OPSTATUS is marked as "FAILED", we will need to update the index properties in the Geodatabase through ArcCatalog.

Thank you, Christian. It was blank. The index wasn't visible from ArcCatalog, but was visible from Toad. We dropped the index using Toad and then used ArcCatalog to release the locks and create a new index. Thanks for your help.

I'm glad to hear this resolved the issue, Chris. Have a good day!
