Question: I am seeing this ORA-01691
error and my database is hanging:
ORA-01691: unable to extend lob segment WM65NAIP.SYS_LOB0003$$ by 128 in tablespace
NAIP65_DATA
ORA-01691: unable to extend lob segment
WM65NAIP.SYS_LOB003$$ by 1024 in tablespace NAIP65_DATA
How do I correct the
ORA-01691 error?
Answer: The
oerr utility shows the cause and action for the
ORA-01691:
ORA-01691: unable to extend lob segment %s.%s
by %s in tablespace %s
Cause: Failed to allocate
an extent of the required number of blocks for LOB segment
in the tablespace indicated.
Action:
Use ALTER
TABLESPACE ADD DATAFILE statement to add one or more files
to the tablespace indicated.
In this case of an ORA-01691 error, the solution is to
identify the name of the tablespace associated with the LOB
segment and add space to the tablespace using the "alter
tablespace xxx add datafile yyy size zzz" syntax:
alter tablespace
NAIP65_DATA
add datafile
'/u01/app/oracle/
. . . /xxx.dbf
size 10G;
Note: Sometime the ORA-01691 error is truncated to
ORA-1691:
ORA-1691: unable to extend lobsegment WM65NAIP.SYS_LOB0003$$ by 128 in tablespace
NAIP65_DATA
ORA-1691: unable to extend lobsegment
WM65NAIP.SYS_LOB003$$ by 1024 in tablespace NAIP65_DATA
