ORA-01426: Numeric Overflow During Cube Build (Doc ID 1494869.1)

Our cube builds starting failing and we received this error after the cube log table sequence reached 32787.
After recreating the sequence the builds run successfully. This seems to be an unacceptable bug for an enterprise level product.
I have been unable to find a patch on the Oracle support site for it. Is a patch avaliable?

I found what appears to be a related bug Bug 14627371 - ORA-01426: NUMERIC OVERFLOW DURING CUBE BUILD
. This bug is marked as fixed in 12.1 of the database.
I think that you may want to pursue this issue with support to see whether this can be back-ported ton 11.2.0.4.0.

ORA-01426: numeric overflow when creating job

Hello,
When executing the following script to create a job I get the error "ORA-01426: numeric overflow" . When I execute the same script on another database with same version and same configuration I do not get the error and the job is created.
Can anyone help me out solving this issue?
Script:
DECLARE
X NUMBER;
BEGIN
SYS.DBMS_JOB.SUBMIT
( job => X
,what => 'insert into dba.dba_logs values (''SGC'',''TRL03'',sysdate,null);

,no_parse => FALSE
SYS.DBMS_OUTPUT.PUT_LINE('Job Number is: ' || to_char(x));
COMMIT;
END;
Database version: 11.2.0.1

We are planning to migrate to dbms_scheduler, but that's in the future. for now we have this error first to solve.
We also tried the following with dbms_scheduler and it gives the same error. The strange is that in another database with same version and same OS it works fine.

Error message "ORA-01426: numeric overflow"

Could somebody please explain with me examples as when you get this error.
error message "ORA-01426: numeric overflow"
Thank You for your help.

You get 1426 when a number, usually from a caclulation, is too big, or too small for Oracle to represent. For example:
SQL> SELECT POWER(99,99) FROM dual;
SELECT POWER(99,99) FROM dual

ORA-01426: numeric overflow, while migrating "float" values

When I try to insert a value of *2.58612749363472E302* (originally a "float" in SQL DB) into an Oracle column of type float(126), I get this error "ORA-01426: numeric overflow"
I tried changing the column type to BINARY_FLOAT, BINARY_DOUBLE, but I still get same error.
I'm using Oracle SQL Developer (2.1.1.64.45) to migrate a SQL Server 2005 Database to Oracle 11g.
Do you have any thoughts on this? Or workarounds?
Thanks in advance.
Arul

Arul,
I have checked the Migration Workbench documentation where it says for float data -
Oracle® SQL Developer
Supplementary Information for Microsoft SQL Server and
Sybase Adaptive Server Migrations
Release 2.1
Table 2–2 Data Types in Oracle and Microsoft SQL Server or Sybase Adaptive Server
NOTE: If you try to migrate
floating point data greater
than or equal to 1.0E+126
then SQL Developer will fail
to insert this data in the
Oracle database and1 will
return an error.This also
applies to negative values
less than or equal to
-1.0E+126.
So, if I understand it correctly your value of 2.58612749363472E302 is outside this range.
Regards,
Mike

Error ORA-01426: numeric overflow when Creating table with double data type

Hi,
I am using ODP.NET to create a table with data from SQL to Oracle. The problem is with double data type fields that is equivalent to FLOAT(49) in Oracle. My syntax is:
CREATE TABLE SCOTT.ALLTYPES

F2 NUMBER(10),
F3 NUMBER(5),
F4 NUMBER(3),
F5 FLOAT(23),
F6 FLOAT(49),
F7 NUMBER (38,5),
F8 NVARCHAR2(500),
F9 NVARCHAR2(500)
Th error is with field F6 but I am not sure what is the correct type equivalent to double in SQL.
I woul appreciate if anyone can help me with this problem.

Autosolve during cube build

Hello!
Several days ago 14th of December 2008 we had run several cube builds. During these builds OLAP engine performs Data loading and Auto solve it was looking like this in XML_LOAD_LOG

Now OLAP engine refuses to perform Auto solve during build. So log looks like this:

Why OLAP engine refuses do Solve measures during build? Of course it is possible to do solve separately, but why it suddenly stops to perform it?

OLAP error leading to a corrupted AW during cube build

Hi all
My cube load keeps on crashing and the result is a corrupted AW. Sometimes it happens, sometimes it doesn't, thus it is very hard to pin point the cause of the problem
I would like to emphasize that the Alert log and trace files contain general info about the issue but does not help in resolving the problem.
Let me explain what is happening.
I have 6 cubes A, B, C, D , E and F in "MY_AW" and all the cubes are populated via a single dbm_cube.build call as shown below
DBMS_CUBE.BUILD('CUBE_A, CUBE_B, CUBE_C, CUBE_D, CUBE_E , CUBE F', 'C', FALSE, 5, TRUE, TRUE, FALSE);
Here is a brief description of the cube structure
a) CUBE_A, CUBE_B CUBE_C are partitioned along dimension A_A ( i.e. along the same dimension)
b) CUBE_D is partitioned along dimension B_B ( i.e. along a different dimension)
c) CUBE_E and CUBE_F' are NOT partitioned ( These cubes are really tiny, thus no need partitioning them)
All 6 cubes are loaded on a daily basis. Initial reload load is always without any issues. Then the next , say 3 incremental loads would run successfully too.
After that, any further incremental load generates an Oracle error ( as shown below) and the result is a corrupted AW.
It is really frustrating because the error is inconsistent( i.e does not surface always) , although the cube structure is constant across all loads..
Can anybody figure out what is happening here?
Any help would be highly appreciated.

One recent source of AW corruption is
BUG 8664896 - ORA-20000: ORU-10027: BUFFER OVERFLOW - AW VALIDATE
A characteristic error of this bug (which you may see in the alert log) is
+ORA-00600: internal error code, arguments: [xspggepGenPSErase05], [], [], []+
This is fixed in the most recent 11g patches, as described by metalink note 1078454.1, so apply these may clear up the issue.
I also see that you selecting the 'atomic' option in your call to dbms_cube.build. This means you may be a victim of
BUG 11795047 - USING OLAP "ROLLBACK TO FREEZE" CAN DAMAGE AW
The issue is that if you choose to run an atomic build and any error occurs during a slave process, then your AW may end up being corrupted. Choosing FALSE for the atomic argument would not fix the underlying error, but it may stop the subsequent AW corruption. As of writing the fix for this bug is not part of any public OLAP patch, so you would need to get a one-off patch through a service request.
In either case I think a service request would be appropriate here since this is a serious error. You can mention my name if you like and I will help direct the problem to the appropriate developers.

Unexpected Numeric Overflow on empty tables when scanning with DMU

I have an instance of oracle running on an isolated network (oracle 11.2.0.3), on a Windows Server 2008 r2, x64 dell R705 server
When using the DMU to scan tables, I get the following error:
ORA-01426: numeric overflow
DBMS_DUMA_INTERNAL: line 8
DBMS_DUMA_INTERNAL: line 43
at line 1
I get his on multiple tables, but in each case, the table is empty (0 rows)
Can I safely ignore this? How do I get DMU to ignore the errors and continue?
Thanks in advance.

The fix for bug 8743409 is not included in the 11.2.0.1 release. Please check the DMU supported configurations. In order to use DMU on any versions of the database before 11.2.0.3, you need to apply a prerequisite server-side patch on one of the supported configurations. If you can upgrade to 11.2.0.3, there is no need to apply additional patches and the aforementioned fix is included.

Numeric overflow with DBMS_CDC_PUBLISH.CREATE_CHANGE_TABLE

Hello all-
I'm running Oracle 9i on WinXP sp. 2.
I'm trying to create a CDC table with the standard SYS package and am getting a numeric overflow error. The code I'm attempting to execute is this:
BEGIN
sys.dbms_cdc_publish.create_change_table(
OWNER => 'CDC_USER',
CHANGE_TABLE_NAME => 'PA_BUDGET_ENTRY_METHODS',
CHANGE_SET_NAME => 'SYNC_SET',

USER_ID => 'Y',
TIMESTAMP => 'Y',
OBJECT_ID => 'N',
SOURCE_COLMAP => 'N',
TARGET_COLMAP => 'N',
OPTIONS_STRING => NULL);
END;
The error I'm getting is this:
ORA-01426: numeric overflow
ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 299
ORA-06512: at line 2
This happens every time, regardless of the source table i'm trying to capture changes for.
Clearly this is a normal exception (i.e., not only thrown in the CDC packages) so I'm having a hard time figuring out what it could be. Anyone out there familiar with CDC have any thoughts?
Thanks in advance,
James

I tried that but no luck yet, also tried put all in a single line, but the same error. It doesn't something tricky here, but actual problem with package. "ddl_markers" is new to 11g and not much documentation is available on that.
Also setting ddl_markers=N removed 3 columns from Publisher table, and the effect of it on Subscriber's view is still a gray area,

Function - numeric Overflow error

Hi
The loop control variable in a FOR loop is an integer (or similar) it seems; those numbers are simply too big for it.
Change your code to something like:
FOR rec IN 1 .. v_highest_uprn - v_start_uprn + 1 LOOP
