R/3 Table indexes

H All,
We are on data load performance tuning. Here in our Ecc 6.0 production system by SE11 indexes were created for tables on 2008 and data is loading from 2009 full daily.
Is it ok by creating indexes for fields of tables before loading and On what base fields can be selected for index creation?
Thanks
Sunil

Hi,
of course the fields used in the where clause of the select statement.

How to obtain the table index in word use LabVIEW Report Generation Toolkit for Microsoft Office

I created a word templete and it had several tables. When I use the "Word Edit Cell" function in LabVIEW Report Generation Toolkit for Microsoft Office, the function need "table index", and I didn't find any function to get or set the table index in word document. How can I achieve my attention to write value to specified table cell using the "Word Edit Cell" function?
Thanks for reply!
YangAfreet

Hi yangafreet
You do not need to get the table index for the word edit cell.vi from anywhere. LabVIEW will automatically index all the tables in the document. See the attatched vi for an example.

To Use Cursor or TYPE table Index by PLS_integer

Hi All,
Let's see if I have table with no. of records 19,26,20,000.
If I want to loop through all the records which will be a optimized way To Use Cursor or TYPE table Index by PLS_integer.
Please guide.
Thanks.

What is it you want to do to/with the rows you're looping through?
Ideally you want to avoid looping, as that's row by row (aka slow by slow) processing and it's expensive time-wise.
If you're doing DML (insert/update/delete) then you're best off doing it in one sql statement, rather than looping.

Fact Table index vs BIA Index

BIA gurus..
Prior to our BIA implementation we had the drop and rebuild index process variants in our process chains.
Now after the BIA implementation we have the BIA index roll-up process variant included in the process chain.
Is it still required to have the drop and rebuilt index process variants during data load ?
Do the infocube fact table indexes ever get hit after the BIA implementation ?
Thanks,
Ajay Pathak.

I think you still need the delete/create Index variants as it not only helps in query performance but also speeds up the load to your cubes.
Documentation in Perfomance tab:
"Indices can be deleted before the load process and after the loading is finished be recreated. This accelerates the data loading. However, simultaneous read processes to a cube are negatively influenced: they slow down dramatically. Therefore, this method should only be used if no read processes take place during the data loading."

New tables & indexes created do not show up in dba_segments view

Dear all,
I have created 3 tables and some indexes, but these objects do not show up in dba_segments view. Is this a normal behaviour? Previously, with dictionary managed tablespace, I can specify the minimum extent to create, when the table/index is created. But I'm not sure how the locally managed tablespace work. Please do advice. Thank you very much in advance.
I'm using Oracle 11g R2 (11.2.0.1.0) for Microsoft Windows (x64), running on Windows 7.
For the purpose of reproducing this issue, I have created the tablespaces as follow:
CREATE TABLESPACE CUST_DATA
DATAFILE 'd:\app\asus\oradata\orcl11gr2\CUST_DATA01.DBF' SIZE 512K
AUTOEXTEND ON NEXT 256K MAXSIZE 2000K
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 256K
SEGMENT SPACE MANAGEMENT AUTO;
CREATE TABLESPACE CUST_INDX
DATAFILE 'd:\app\asus\oradata\orcl11gr2\CUST_INDX.DBF' SIZE 256K
AUTOEXTEND ON NEXT 128K MAXSIZE 2000K
EXTENT MANAGEMENT LOCAL UNIFORM SIZE 128K
SEGMENT SPACE MANAGEMENT AUTO;
CREATE TABLE CUSTOMER_MASTER (CUST_ID VARCHAR2 (10),
CUST_NAME VARCHAR2 (30),
EMAIL VARCHAR2 (30),
DOB DATE,
ADD_TYPE CHAR (2) CONSTRAINT CK_ADD_TYPE CHECK (ADD_TYPE IN ('B1','B2','H1','H2')),
CRE_USER VARCHAR2 (5) DEFAULT USER,
CRE_TIME TIMESTAMP (3) DEFAULT SYSTIMESTAMP,
MOD_USER VARCHAR2 (5),
MOD_TIME TIMESTAMP (3),
CONSTRAINT PK_CUSTOMER_MASTER PRIMARY KEY (CUST_ID) USING INDEX TABLESPACE CUST_INDX)
TABLESPACE CUST_DATA;
SQL> SELECT TABLE_NAME, TABLESPACE_NAME
2 FROM USER_TABLES
3 WHERE TABLE_NAME LIKE 'CUST%';
TABLE_NAME TABLESPACE_NAME
CUSTOMER_MASTER CUST_DATA
SQL> SELECT INDEX_NAME, TABLESPACE_NAME
2 FROM USER_INDEXES
3 WHERE TABLE_NAME LIKE '%CUST%';
INDEX_NAME TABLESPACE_NAME
PK_CUSTOMER_MASTER CUST_INDX
SQL> SELECT SEGMENT_NAME, SEGMENT_TYPE, TABLESPACE_NAME, BYTES
2 FROM USER_SEGMENTS;
no rows selected

Prior to 11g, when you created a table or whatever, you automatically allocated one extent.
This is now no longer true and depends on a parameter I don't remember.
dba_segments is a summary of dba_extents.
Obviously, if there is no extent allocated, the table (view is defined with inner join) will not show up.
You could qualify this is as a bug and submit a SR to Oracle. But then the performance impact may be huge.

BWA Fact Table Index Size

Hi
Can anybody tell me how the BWA decides when a fact table index gets split into multiple parts? We have a number of very large cubes that are indexed and some have a fact table index that consists of one logical index which is made up of multiple physical indexes but other, similar sized cubes, just have one very large physical index for the fact table.
With the one very large physical index we seem to get an overload problem but when they are split into multiple parts we don't.
Thanks
Martin

Hi Martin,
this depends on the reorg config and the attribute of the index. You can manually trigger a splitting of an index via command 'ROUNDROBIN x', x stand for the number of parts which the index will be split to. Therefore you have to go into trexadmin standalone tool -> landscape right click on index -> split/merge index...
If you want an automatically split, you have to setup your reorg settings. Goto trexadmin standalone tool -> tab reorg -> options -> here you can choose the type of algorithm. Have a look into note 1313260 and 1163149.
Do you have a scheduled reorg job?
Regards,
Jens

Is it permissable to extend an SAP-provided table index?

(Please note I realize this might not be the best forum for this post; I did look at ABAP development, SAP on Oracle, and a few others, but given some other threads, it seemed like this might be the best place for it. Apologies if not).
We have a very large table (GMIA), and I noticed that two customer-created indexes can essentially be combined into one because the first index is RGRANT_NBR plus fields A and B, and the second index is RGRANT_NBR plus fields A, B, C, D, and E. So I might as well get rid of the first index and just keep the second one having RGRANT_NBR plus fields A through E.
However, I noticed that SAP-provided index 4 contains simply one field - RGRANT_NBR. So ideally, I could just add fields A, B, C, D, and E to index 4, then I could get rid of my second customer-created index.
Question: Is it permissable to extend an SAP-provided index like this? As a developer, I'm not in the modifying SAP objects business, but this is the first time I've been presented this situation with a table index. Given that our GMIA table has MILLIONS of records in it, getting rid of another customer-created index completely might be a great opportunity.
Thoughts?
Dave

I really don't have a requirement for this. I'm a developer, and I've noticed some of our biggest timeout issues concern programs that hit table GMIA. So I thought I'd take a look at GMIA and our indexes to learn more about it via SE11 and DB02.
In our Production environment, we have over 88 million records in this table for a table size of 38.23 GB. Aside from the 6 SAP-provided indexes, 8 customer indexes have been created by others over time. It was in looking at these indexes that I noticed our 8th customer index, ZS8, is essentially the same 3 fields as ZS3, plus a few more fields. Ideally, ZS8 should NOT have been created, and ZS3 should have simply been extended with the additional fields.
It was suggested to me in another thread a long while back that I could potentially get rid of ZS3 as well and just make SAP index 4 look like ZS8 because SAP index 4 is just indexed by Grant Number (RGRANT_NBR). ZS8's first index field is Grant Number followed by 5 or 6 additional fields. That's why I was wondering if it was even a "thing" or a possibility to extend an SAP index, but customizing an SAP component makes Dave a very, VERY nervous boy.
Basically, I'm alarmed at the number of records in the table and the number of indexes we have. There's no archiving strategy here, so I probably can't do anything about the number of records in GMIA, which go back to 2006 when we first went live with SAP. But I can clearly get rid of one customer-created index (ZS3). And if I can deactivate SAP index 4, I would assume the system would then automatically use ZS8 since the first field is Grant Number for situations where it would have used SAP index 4.
So that's the background here. Honestly, I don't know how much improvement these things will make, but getting rid of ZS3 will save 5 GB of space, and presumably "deactivating" SAP index 4 would save almost 5 GB as well. I'm assuming we might see some negligible performance gains on our table operations involving GMIA, but it's still a beast with a large number of indexes, so I don't know.
I'm really, really interested in hearing from others' thoughts and recommendations -- your input is MOST welcome here!

Problem with table-indexes when using select-options in select

Hello experts,
is it right that table-indexes will not be used if you take select-options to select data from the database?
in detail:
i have build up an table-index for one of our db-tables and test it via an test-programm. The first test with '=' comparisons worked fine. Every key of the index was used; checked via ST05!
e.g.:    SELECT * FROM TABLEA INTO ITAB WHERE keya = '1' AND keyb = '2' AND keyc = '3'.
Now i startet the test with select-options
e.g.:   SELECT * FROM TABLEA INTO ITAB WHERE keya IN seltabA AND keyb IN seltabB AND keyc IN seltabC.
First of all i just filled the seltabs with only 1 value:    eg: seltabA=      SIGN = 'I'   OPTION = 'EQ'   LOW = '1'     etc.
Everything worked fine. Every key of the index was used.
But now, I putted more than one entries in the seltabs e.g.
seltabA:      SIGN = 'I'   OPTION = 'EQ'   LOW = '1'
                   SIGN = 'I'   OPTION = 'EQ'   LOW = '2'
                   SIGN = 'I'   OPTION = 'EQ'   LOW = '3'
From now on, the indexed was not used completely (with all keys).
Isn't that strange? How can i use select-options or sel-ranges with using the complete table-indexes?
Thanks a lot,
Marcel

Hi Hermann,
i hope this helps:
this is the first one, which uses the complete index:
SELECT
"KOWID" , "LIFNR" , "KLPOS" , "ORGID" , "KOART" , "MATNR" , "GLTVON" ,
"GLTBIS" , "WERT" , "ABLIF" , "FAKIV" , "AENAM" , "AEDAT" , "AFORM" ,
"HERSTELLER" , "ARTGRP" , "OE_FREITXT" , "ARTFREITEXT" , "STATUS" ,
"TERDAT"
FROM
"/dbcon/01_con"
WHERE
"MANDT" = ? AND "LIFNR" = ? AND "ORGID" = ? AND "KOART_BASIS" = ? AND
"STATUS" = ? AND "GEWAEHR_KOWID" < ? AND ( "STATUS" = ? OR "STATUS" = ? OR
"STATUS" = ? ) WITH UR
RESULT: 5 IXSCAN /dbcon/01_con05 #key columns: 4
And the second one, which does not use the complete index! The 3 ranges are filled each with 2 values. Remember; when i fill them each with only one value, the result is the same as you can see above(/dbcon/01_con05 #key columns: 4):
SELECT
"KOWID" , "LIFNR" , "KLPOS" , "ORGID" , "KOART" , "MATNR" , "GLTVON" ,
"GLTBIS" , "WERT" , "ABLIF" , "FAKIV" , "AENAM" , "AEDAT" , "AFORM" ,
"HERSTELLER" , "ARTGRP" , "OE_FREITXT" , "ARTFREITEXT" , "STATUS" ,
"TERDAT"
FROM
"/dbcon/01_con"
WHERE
"MANDT" = ? AND "LIFNR" IN ( ? , ? ) AND "ORGID" IN ( ? , ? ) AND
"KOART_BASIS" IN ( ? , ? ) AND "GEWAEHR_KOWID" < ? AND ( "STATUS" = ? OR
"STATUS" = ? OR "STATUS" = ? ) WITH UR
and here the access-plan
   0 SELECT STATEMENT ( Estimated Costs = 5,139E+01 [timerons] )
5     1 RETURN
5     2 NLJOIN
5     3 [O] TBSCAN
5     4 SORT
5 TBSCAN GENROW
5     6 <i> FETCH /dbcon/01_con
7 IXSCAN /dbcon/01_con05 #key columns: 2
As you can see, only 2 keys were taken for indexed selection!
Any idea?
Kind regards,
MArcel

SQL Developer Behavior When Gathering Table/Index Statistics

Hey All,
Not sure if this has been posted yet. I did a search and did not find any threads on the topic though.
I noticed with SQL Developer 2.x, when you using the context menu to gather table/index statistics for a given table, you get no modal progress/waiting window like you did in 1.x. It just kind of "does nothing", even though it did actually execute the DBMS_STATS package. If you press cancel and try to navigate around, you get multiple "Connection is Busy" errors. Eventually it will come back and say "Statistics gathered for table <whatever>". In the old versions there was just a modal window with an animated progress bar while it ran the DBMS_STATS package. What happened to that? Or is this something unique to my install? Anyone else ran into this? Is there a fix or somewhere I can report this as an official bug? FWIW I'm running 2.1.1.64, and this did occur in the initial 2.0 release.
It is very confusing the first time you run into it... I pressed the "apply" button several times thinking it didn't take, but it ended up running the DBMS_STATS for every click I did.
Thanks!

Same happens to all the other context menu opened dialogs. Indeed very confusing at first and disturbing.
The only official site to report bugs is Metalink/MOS, but you might be lucky if someone from the team picks it up here.

K.

How can I remove the error? How to use index in where clause I'm not getting and on which key? or, should I use the statement "EC C1_NOFIRST to remove the error?
Kindly guide.

> should I use the statement "EC C1_NOFIRST to remove the error?
you can not really ask this question in this forum. This check gives you hints to the most serious problems in database accesses, if you want to override it, then you should better forget about performance.
If you are not familiar how databases use indexes, then check resources in the net or in books, in
short they use indexes and the indexes are absolutly necessary with large tables, if you want to get
good performance.
But indexes can only be used in the order of their field, until a field is not used in the WHERE-condition, (gap). If the gap is already the first field, then the index can not be used at all.
In your case there is not first field of any index specified in the WHERE condition, so the SELECT might be slow. Either you can add a condition on a first index field or you have to live with a poor performance.

Table index size in DB02 smaller after upgrade

SAP ERP 6.0, DB2 9.5, AIX 5.3. After we upgraded to SPS 15 / EHP4 / Netweaver EHP1 SPS02 using the downtime minimized method (shadow instance created) the index sizes for the tables are showing reduced sizes. When looking in DB02 under History -> "tables and indexes" all the tables show a drop in index sizes. I have compared the indexes to a pre upgrade copy of the system and all the indexes are still defined and active in the upgrades system. Can somebody please explain why the size drop? Is this a reporting error or what?

Hi Eddie,
DB2 V8.2 did not allow to retrieve table/index size information from DB2 directly. Therefore the SAP DB2 database interface and the CCMS code tried to do some size estimation based on cardinality and table/index width. DB2 V9.1+ provides table function ADMIN_GET_TAB_INFO to retrieve size information directly from DB2. Since this size information is much more accurate the SAP DB2 database interface and the CCMS code have been changed to use this table function.
So the phantom-"shrink" you observed may be related to the switch from size estimation to the size retrieved from ADMIN_GET_TAB_INFO . This may have happened directly after the V9.5 upgrade ( size retrieved differently in SAP DB2 database interface ) or after the SAP release upgrade ( change in CCMS ABAP coding ).
