Oracle 8.17/ Windows NT

Hello

I have a qucik question, just looking at the tablespace schema DBA studio manager,

I see that i have 68% of my RBS tablespace used up. The Dbse is running in noarchive log mode.

The oonly production type activity that runs is a series of daily updates from a remote data source...

Users then periodically write short queries against this data.

Is this healthy to have 62% used like this?? It seems very high

Thanks in advace for any help...
