[oracle@rh2 ~]$ oerr ora 1652 01652, 00000, "unable to extend temp segment by %s in tablespace %s" // *Cause: Failed to allocate an extent of the required number of blocks for // a temporary segment in the tablespace indicated. // *Action: Use ALTER TABLESPACE ADD DATAFILE statement to add one or more // files to the tablespace indicated. Bug 6977045 ORA-1652 even though there is sufficient space in RECYCLE BIN This note gives a brief overview bug 6977045. The content was last updated on: 06-DEC-2010 Click here for details of each of the sections below. Affects: Product (Component) Oracle Server (Rdbms) Range of versions believed to be affected Versions BELOW 11.2 Versions confirmed as being affected 11.1.0.7 Platforms affected Generic (all / most platforms affected) Fixed: This issue is fixed in 11.2.0.1 (Base Release) 11.1.0.7 Patch 32 on Windows Platforms Symptoms: Related To: Error May Occur Storage Space Usage Affected ORA-1652 Recycle Bin Description Under space pressure an ORA-1652 may be signalled even if there is sufficient space in the recyclebin. Rediscovery Notes: Under space pressure, space allocation fails, even though there is sufficient free space in recycle bin. Workaround Turn off the recycle bin. OR Purge the recyclebin. Hdr: 12582291 11.1.0.7 RDBMS 11.1.0.7 SPACE PRODID-5 PORTID-59 Abstract: UPDATING A LOB FAILS WHILE CLEARING RECYCLE BIN EVEN WHEN ENOUGH FREE SPACE IS A BUG TYPE CHOSEN =============== Code SubComponent: Recovery ====================== DETAILED PROBLEM DESCRIPTION ============================ An OCI application module tried to update a LOB object, and this operation internally & recursively tried to clear off a few segments from the recycle bin. As ct. had enabled triggers preventing uncontrolled droppings of segments, this apparently prevented the application module from succeeding. Further, since this error did not show up on the application module that failed, this customer-facing critical application of this large enterprise was down for considerable time. DIAGNOSTIC ANALYSIS =================== None. This bug is raised mainly as a Q/A to get clarifications for customer, who is demanding an answer and possible action plan so that they can prevent such disastrous situation in future. WORKAROUND? =========== Yes WORKAROUND INFORMATION ====================== Disable the trigger or not using the recycle bin (Though neither operation is acceptable to ct. because of their business reasons). TECHNICAL IMPACT ================ Critical application module fails. RELATED ISSUES (bugs, forums, RFAs) =================================== None (MOS Note 978045.1 was referenced by ct.)

If you have enabled recyclebin ,then you should check tablespace free space with dba_free_space and recyclebin space also like:
create view dba_free_space_pre10g as select ts.name TABLESPACE_NAME, fi.file# FILE_ID, f.block# BLOCK_ID, f.length * ts.blocksize BYTES, f.length BLOCKS, f.file# RELATIVE_FNO from sys.ts$ ts, sys.fet$ f, sys.file$ fi where ts.ts# = f.ts# and f.ts# = fi.ts# and f.file# = fi.relfile# and ts.bitmapped = 0 union all select /*+ ordered use_nl(f) use_nl(fi) */ ts.name TABLESPACE_NAME, fi.file# FILE_ID, f.ktfbfebno BLOCK_ID, f.ktfbfeblks * ts.blocksize BYTES, f.ktfbfeblks BLOCKS, f.ktfbfefno RELATIVE_FNO from sys.ts$ ts, sys.x$ktfbfe f, sys.file$ fi where ts.ts# = f.ktfbfetsn and f.ktfbfetsn = fi.ts# and f.ktfbfefno = fi.relfile# and ts.bitmapped <> 0 and ts.online$ in (1, 4) and ts.contents$ = 0 / create view dba_free_space_recyclebin as select /*+ ordered use_nl(u) use_nl(fi) */ ts.name TABLESPACE_NAME, fi.file# FILE_ID, u.ktfbuebno BLOCK_ID, u.ktfbueblks * ts.blocksize BYTES, u.ktfbueblks BLOCKS, u.ktfbuefno RELATIVE_FNO from sys.recyclebin$ rb, sys.ts$ ts, sys.x$ktfbue u, sys.file$ fi where ts.ts# = rb.ts# and rb.ts# = fi.ts# and u.ktfbuefno = fi.relfile# and u.ktfbuesegtsn = rb.ts# and u.ktfbuesegfno = rb.file# and u.ktfbuesegbno = rb.block# and ts.bitmapped <> 0 and ts.online$ in (1, 4) and ts.contents$ = 0 union all select ts.name TABLESPACE_NAME, fi.file# FILE_ID, u.block# BLOCK_ID, u.length * ts.blocksize BYTES, u.length BLOCKS, u.file# RELATIVE_FNO from sys.ts$ ts, sys.uet$ u, sys.file$ fi, sys.recyclebin$ rb where ts.ts# = u.ts# and u.ts# = fi.ts# and u.segfile# = fi.relfile# and u.ts# = rb.ts# and u.segfile# = rb.file# and u.segblock# = rb.block# and ts.bitmapped = 0 /
dba_free_space_pre10g which shows the real free space like 9i behavior , dba_free_space_recyclebin shows free space resided in recyclebin.
