    ORA-1652: unable to extend temp segment by 38400 in tablespace

    Hi

    ORA-1652: unable to extend temp segment by 38400 in tablespace MST.

    How to resolve the above error. This error populating very frequently in alert.log. The mentioned tablespace is categorized as permanent tablespace. How to find out which segment is causing the problem. MST tablespace is enough free space.


    Thanks in Advance.

    One of your sessions must be failing -- which one is getting the error?

    do you use that for temporary tablespace?

    do you rebuild index to that tablespace?

    do you move tables to that tablespace?

    No. Users temporary tablespace designated as TEMP.
    No. No rebuilding indexes
    No. not moving any tables.

    But I extracted one particular query during the error which is

    SELECT /*+ ordered USE_NL(PIR_DATES_TXN) USE_NL(b) INDEX(GL_AUDIT_TXN
    XFR_GLAUDIT_TXN_REF_NMBR) */ ......

    could that be causing?

    Thanks In Advance.

    It might be helpful to put the following in init.ora and restart the database:

    EVENT="1652 TRACE NAME ERRORSTACK LEVEL 3"

    This will generate a trace file each time ORA-01652 occurs. The trace file should contain the offending SQL.

    I can not restart the database 24/7. I have used
    alter system set events '1652 trace name errorstack level 3'. But no trace files have been generated. What could be the problem. Do I need to use dbms_system.set_ev?

    Thanks In advance.

    select * from dba_segments where next_extent > 38400 * db_block_size

    and see what's the segment causing the problem

    Thanks pando.
    select segment_name,segment_type from dba_segments where next_extent >= (38400 * 8192)

    SEGMENT_NAME SEGMENT_TYPE
    -------------------------------------------

    SYS_IL0000011225C00004$$ LOBINDEX
    SYS_IL0000010344C00005$$ LOBINDEX
    SYS_LOB0000011225C00004$$ LOBSEGMENT
    SYS_LOB0000010344C00005$$ LOBSEGMENT

    Thanks In Advance.
