As per the plan, I logged into both the source and target hosts today to initiate the requested database restore. I performed all the preliminary checks, and everything was in order.
However, just before starting the restore, I observed that the target filesystem size is exactly 2.6 TB, which is the same as the current size of the source database. This presents a risk of failure, as there is a high possibility that additional space will be required during the restore process. Proceeding with the restore under these conditions could result in an incomplete or abandoned database on the target side.
I also explored whether any tablespaces on the source database could be resized to reduce its footprint, but unfortunately, no space could be reclaimed at this time.
At this point, the only viable option is to request the DI team to allocate additional space on the ACFS filesystem at the target side to safely accommodate the full restore and ensure operational integrity.
Please let me know how you'd like to proceed, and I can coordinate with the DI team accordingly.
Best regards,
