Hi DBA's
Our production database has a tablespace with the following schema:
CREATE TABLESPACE IRD_DATA_LARGE
DATAFILE 'E:\ORANT\DATABASE\USR1PROD.ORA' SIZE 128472K AUTOEXTEND ON
NEXT 2K MAXSIZE UNLIMITED
LOGGING
DEFAULT STORAGE(INITIAL 100K
NEXT 100K
MINEXTENTS 1
MAXEXTENTS 121
PCTINCREASE 1)
ONLINE
PERMANENT
This tablespace has only 2MB of free space available.
The fragmentation index is 58.7
The largest table is 29MB and has 5 extents.
I've observed some segments with Max Extents different than 121 which is the
default and how most of the segments were created.
I know I need to add another datafile, however, I'd like to find out what
would happen if a segment requested another extent that was larger than the
available free space in the tablespace. Since AUTOEXTEND is enabled is there
a possibility that this situation could cause the tablespace or instance to
go offline or crash?
Thanks for your comments and advice!
