Fragmentation, should I worry?

edited Oct 22, 2018 11:34AM in Database Administration (MOSC) 9 commentsAnswered ✓

I have a cronjob, setup previously by an ex-dba to check the tablespace for it's fragmentation, I observe from the weekly report that the fragmentation is increasing & the report is stating dangerous fragmented. Since this is a production instance and rather large as well (2TB) I can't get the downtime to do the defragmentation. Is there any impact if I left it as it is and do the defragmentation only when I can get a downtime? Will there be any impact towards performance? Understand that there will be wasted space due to this.

My DB version is 11.1.0.7.0 with segment space management set to AUTO.

Howdy, Stranger!
