I have searched the forum, internet, docs, maybe I get the question wrong or do I understand it wrong? I have no idea.
This is the theory:
1. I create a 32,000 MB datafile, starting at 1000MB, increase every 1000 MB.
2. At 5000 MB, a monitoring software says that the tablespace/datafile is less than 10% free. I know the issues is might be with monitoring software, etc, etc, so on and so forth.
Let just say, for a long while, the data might stays at 4900 MB.
But the key question is this: Is there a command to force a datafile to extend by its original extend value? So if I call it once, the datafile will increase by 1000 MB, making it 6000. And if I call it again, it will become 7000 (out of maximum 32,000).
Just to keep the monitoring software silent? Because by adding 2000 MB free space, the monitoring software will no longer complain.
