Index for group by
Oracle 10g:
Does having index help when doing query by "group by"?
For eg: select aa, count(*) from B group by aa

Hello,
as yo used count(*) a full table scan will be performed. If you use a col1 that was indexed,
like col1 for a count, not group by, an index scan will be performed, but be carefull if there
is no null in table col1, the amount will be incorrect.
RegardsSo I didn't understand that null col will destroy the count. Also why wouldn't having index help when doing group by?

NLSRTL Version 11.1.0.7.0 - ProductionThe table has 28 columns none indexed the columns mentioned here have non unique values.
The table approved has more than 10million records and the query is taking a huge time.
The query first tries to restrict the search to only valid entities and cc (already indexed and working fine).
The cardinality of allocations, projects is around 1000, entity is 3000, and cc is around 50,000, reference number = 2000, financialyear = 4
Please suggest which index would be best to use on these columns given that there will no updations but frequent insertions.
If nothing else works than I will need to change it to pre aggregated data for overnight run .

Index for "group by" statement.
Hi,
I have a statement directed at the GLPCP table.
It sums op the plan number in each month.
In ABAP it looks like this
SELECT ryear rprctr racct kostl ps_psp_pnr rfarea
SUM( hsl01 ) SUM( hsl02 ) SUM( hsl03 )
SUM( hsl04 ) SUM( hsl05 ) SUM( hsl06 )
SUM( hsl07 ) SUM( hsl08 ) SUM( hsl09 )
SUM( hsl10 ) SUM( hsl11 ) SUM( hsl12 )
INTO TABLE e_t_data
FROM glpcp
WHERE kokrs EQ '0020'
AND ryear IN l_r_year
AND rldnr EQ '8A'
AND rrcty EQ '1'
AND rvers EQ '010'
AND rbukrs EQ '0020'
GROUP BY ryear rprctr racct kostl ps_psp_pnr rfarea.
I have created an index on KOKRS, RYEAR, RLDNR, RRCTY, RVERS, RBUKRS. To support the where statement.
This speeds up the process some but i believe that greater performance can be achieved.
I ran the expression through the SQL explain routine.
The path looks like this http://yfrog.com/jdexplainpathj
It came out with poor performance regarding the group by sentence.
Explanation of query block number: 1 step: 2
Query block type is SELECT
Performance appears to be bad
Method:
. additional sorts needed
. for the composite table (current result table)
. the sorts are performed
. - to meet an GROUP BY
. unknown or no prefetch is used
How can i build an index to support the group by sentence.
Best Regards
- RasmusHi Hermann,
I can see why you are confused. It is hard to keep track with the changes.
I will sum up:
The abap statement.
SELECT ryear rprctr racct kostl ps_psp_pnr
SUM( hsl01 ) SUM( hsl02 ) SUM( hsl03 )
SUM( hsl04 ) SUM( hsl05 ) SUM( hsl06 )
SUM( hsl07 ) SUM( hsl08 ) SUM( hsl09 )
SUM( hsl10 ) SUM( hsl11 ) SUM( hsl12 )
INTO TABLE it_glpcp
FROM glpcp
WHERE kokrs EQ '0020'
AND ryear IN l_r_year
AND rldnr EQ '8A'
AND rrcty EQ '1'
AND rvers EQ '010'
AND rbukrs EQ '0020'
GROUP BY rprctr racct kostl ps_psp_pnr ryear.
The SQL statement mad from the abap:
SELECT
"RYEAR" , "RPRCTR" , "RACCT" , "KOSTL" , "PS_PSP_PNR" ,"RFAREA" , SUM( "HSL01" ) , SUM( "HSL02" ) ,
SUM( "HSL03" ) , SUM("HSL04" ) , SUM( "HSL05" ) , SUM( "HSL06" ) , SUM( "HSL07" ) , SUM("HSL08" ) ,
SUM( "HSL09" ) , SUM( "HSL10" ) , SUM( "HSL11" ) , SUM("HSL12" )
FROM
"GLPCP"
WHERE
"RCLNT" = ? AND "KOKRS" = ? AND "RYEAR" =? AND "RLDNR" = ? AND "RRCTY" = ? AND "RVERS" = ? AND "RBUKRS"
= ?GROUP BY "RYEAR" , "RPRCTR" , "RACCT" , "KOSTL" , "PS_PSP_PNR" ,"RFAREA" FOR FETCH ONLY WITH UR
The index no. 9.

Errors in the OLAP storage engine: An error occurred while processing the indexes for the partition of the measure group of the cube from the database.
I have dropped and recreated a fact table to refresh the data as the table is having identity columns. So not able to directly insert data. After that cube is throwing above error.
Please suggest.Hi Md,
It hard to analyse the issue base on the limited information, Are there any error message on the log? Under C:\Program Files\Microsoft SQL Server\MSAS11.\OLAP\Log (this could be different for your server), there are 3 log files that are generated:
msmdrrv.log
FlightRecorderCurrent.trc
FightRecorderBack.trc
The msmdrrv.log simply points to the other two logs. There might be some detail information for this error. Please provide us the detail information about it, so that we can make further analysis.

Index File group on same drive as data files
I've just found a file group used for indexes on the same drive as the data files.
Am i correct in saying there is little benefit to this. The index file group should be on it's own spindle?
Mr Shaw... One day I might know a thing or two about SQL Server!Definitely there will be performance gain provided you are querying for related data which as references index on those index filegroups.
It helps in parallel processing , having data and index on multiple disk heads helps in reading the data parallel. For more information you can refer the below link

More than one index for a column.
Hi,
I am trying to create more than one index for a particular column of the table.But oracle does not allow more than one index for a column.
I just want to make sure whether we can add more than one index for a column
and if yes what are the scenarios.
Because as far as i know some database allows more than one index for a single column.You cannot create more than one index for the same column(s).This is not so true Nicolas. Look at following example:
SQL> create index idx_mytest_id on mytest(id);
Index created.
SQL> create index idx_mytest_id_desc on mytest(id desc);
Index created.
SQL> create index idx_fbi_mytest_id_upper on mytest(upper(id));
Index created.
SQL> create index idx_fbi_mytest_id_upper_desc on mytest(upper(id) desc);
Index created.
SQL> create index idx_fbi_mytest_id_lower_id on mytest(lower(id));
Index created.
SQL> create index idx_fbi_mytest_id_lower_id_dsc on mytest(lower(id) desc);
Index created.
SQL> create index idx_fbi_mytest_id_tr_up on mytest(trunc(upper(id)));
Index created.
-- I can still continue but for this example this will be enough
SQL> select index_name from dba_indexes where table_name = 'MYTEST';
INDEX_NAME
IDX_MYTEST_ID
IDX_FBI_MYTEST_ID_UPPER
IDX_MYTEST_ID_DESC
IDX_FBI_MYTEST_ID_UPPER_DESC
IDX_FBI_MYTEST_ID_LOWER_ID
IDX_FBI_MYTEST_ID_LOWER_ID_DSC
IDX_FBI_MYTEST_ID_TR_UP
7 rows selected.You can see 7 indexes for one column (ID) and I could still continue...
So according this test we can say you can't create more than one index for one column (or the same group of columns in case of composite index) with same condition(s).

Creating index for a big table
Hello,
We have Oracle 9.2
I have two tables TableA and TableB. TableB is created by copying part of the content of TableA. Inorder to speed up the coping process, I dropped the primary index of TableB. Now TableB has 94 million records.
Now I was trying to create the primary index for TableB with the following script:
CREATE UNIQUE INDEX USR3."TableB~0"
ON USR3.TableB(ID,COUNTER)
PCTFREE 10
INITRANS 2
MAXTRANS 255
TABLESPACE INDEX1
STORAGE(FREELISTS 1
FREELIST GROUPS 1
BUFFER_POOL DEFAULT)
LOGGING
NOPARALLEL
NOCOMPRESS
And I get the Oracle catch all error (ora-00600: internal error....)
And I only have the following error message: "kcbvmap: unable to find victim buffer"
The tablespace is a locally managed tablespace
Please help, how do I fix this problem.CREATE UNIQUE INDEX USR3."TableB~0"

Why is the Star Transformation using two indexes for the same dimension?
Hi,
Recently, I have made an investigation about the Star Transformation feature. I have found a strange test case, which plays an important role in my strategy for our overall DWH architecture. Here it is:
The Strategy:
I would like to have the classical Star Transformation approach (single column Bitmap Indexes for each dimension foreign key column in the fact table), together with additional Bitmap Join Indexes for some of the dimension attributes, which would benefit from the materialization of the join (bitmap merge operation will be skipped/optimized).
The query:
select dp.brand, ds. region_name, dc.region_name
, count(*), sum(f.extended_price)
from fact_line_item f
, dim_part dp
, dim_supplier ds
, dim_customer dc
where dp.mfgr = 10 -- dimension selectivity = 1/10 --> acttual/fact selectivity = 6/10
and f.part_dk = dp.dk
and ds.region_name = 'REGION #1' -- dimension selectivity = 1/9
and f.supplier_dk = ds.dk
and dc.region_name = 'REGION #1' -- dimension selectivity = 1/11
and f.customer_dk = dc.dk
group by dp.brand, ds. region_name, dc.region_name

The Question:
Why is the Star Transformation using both indexes FACT_LI__P_PART_DIM_KEY_BIX and FACT_LI__P_PART_MFGR_BJX for the same dimension criteria (dp.mfgr = 10)?? The introduction of the additional Bitmap Join Index actually make Oracle to do the work twice !!!
Anybody, any idea ?!?Dom, here it is the plan with the predicates:

Planning to implement multiple column(Userdatastore) text index on dummy column appended to organizations table. And write triggers on other child tables to trigger the sync for Text index.
But not sure whether we can rewrite this above sql query by replacing union into joins, not sure why developer has not done so.
Can anyone please help me in creating text index for this sql. I do not want to approach cartesian joins as these are having parent-child relationship.
Oracle Version: 10.2.0.4
Please let me know if you need more information1 .As text index is created in parent table on id column, can we somehow search only from particular columns(Parent or child) by using user_datastore and tags for sectioning it?
Below are the sql which i need to make use of text index
select m.id from id_ALIAS_NAMEs an
join organizations m on(m.id=an.id)
where lower(ID_ALIAS_NAME) like 'technology%' and m.id_data_provider<100;
select M.id,ID_ALIAS_NAME,'ID_ALIAS_NAME' AS NAMETYPE
from id_alias_names an JOIN organizations m ON m.id=an.id
where id_data_provider<100 AND coalesce(m.ID_COUNTRY_OF_DOMICILE,m.ID_COUNTRY_OF_INCORPORATION)='US'
AND LOWER(ID_ALIAS_NAME) like LOWER('TECHNOLOGY%')
and F_GetFirstWord(ORG_ALIAS_NAME)='TECHNOLOGY'
The text index must be created on a text column, not a numeric id column. It is common to create it on a dummy column. You can name that column anything you like instead of dummy, like search_columns or some such thing. You can add tags in your procedure, so that your resulting virtual column is like xml data. You can then create a section group, so that you can search within each of those tags. In the example below, I used ctxsys.auto_section_group because it is the simplest to create, but you may get better performance by using another type of section group and naming each individual tag.

Configuring Browsing Indexes for Service Search Descriptor Filters
I am running DSEE 6.1 on Solaris 10.
I restrict access to the ldap clients (solaris8, 9, and 10) for various users in the Directory by configuring the service search descriptors to use a filter based on specific roles. Each servers profile mentions a role depending on type of server and then users are assigned roles which are nested within specific server type roles:
NS_LDAP_SERVICE_SEARCH_DESC= passwd:ou=People,dc=example,dc=com?one?nsrole=cn=serverRole,ou=profile,dc=example,dc=com
NS_LDAP_SERVICE_SEARCH_DESC= group:ou=group,dc=example,dc=com?one
NS_LDAP_SERVICE_SEARCH_DESC= audit_user:ou=People,dc=example,dc=com?one?nsrole=cn=serverRole,ou=profile,dc=example,dc=com
NS_LDAP_SERVICE_SEARCH_DESC= shadow:ou=People,dc=example,dc=com?one?nsrole=cn=serverRole,ou=profile,dc=example,dc=com
NS_LDAP_SERVICE_SEARCH_DESC= user_attr:ou=People,dc=example,dc=com?one?nsrole=cn=serverRole,ou=profile,dc=example,dc=com
I have noticed in my error logs on the Directory servers messages regarding these filters not being indexed:
WARNING<20805> - Backend Database - conn=949139 op=1 msgId=2 - search is not indexed base='ou=people,dc=example,dc=com' filter='(nsRole=cn=serverRole,ou=profile,dc=example,dc=com)' scope='one'
I have also had a few instances where the naming services seems to have stopped altogether. This seems to be timed with when my clients do a refresh of the ldap cache - which is the time that I seed the not indexed messages in the error log.
I guess that I need to set up Browsing Indexes for these filters
Can anyone give examples how to do this?
I guess I will need a vlvBase of ou=people,dc=example,dc=com
vlvScope of 1
vlvFilter of nsRole=cn=serverRole,ou=profile,dc=example,dc=com
I am not sure what I would do for vlvsort attributes though??The access logs shows that the attributes to be sorted are uid and cn:
25/Apr/2008:09:58:21 +1200] conn=171835 op=1 msgId=2 - SRCH base="ou=people,dc=example,dc=com" scope=1 filter="(nsRole=cn=serverRole,ou=profile,dc=example,dc=com)" attrs="cn uid uidNumber gidNumber gecos description homeDirectory loginShell"
[25/Apr/2008:09:58:21 +1200] conn=171835 op=1 msgId=2 - SORT cn uid (1426)
[25/Apr/2008:09:58:21 +1200] conn=171835 op=1 msgId=2 - VLV 0:999:0:0 1:1426 (0)
[25/Apr/2008:09:58:26 +1200] conn=171835 op=1 msgId=2 - RESULT err=0 tag=101 nentries=999 etime=5 notes=U
So the vlvsort attributes should be cn and uid. -
ESH_ADM_INDEX_ALL_SC cannot perform initial indexing for all search connectors
Dear SAP Gurus,
We are implementing TREX version 7.10.50 for Talent Management ECC 6.0 - EHP 5.
I'd like to ask you question regarding ESH_ADM_INDEX_ALL_SC program
which used to create search connector for TREX and perform initial indexing for all search connectors.
As we know we can perform indexing using ESH_COCKPIT transaction code or use ESH_ADM_INDEX_ALL_SC.
If I try to perform indexing using ESH_COCKPIT, all search connectors can be indexed ("searchable" column are "checked" and status are changed to "Active" for all search connectors).
However, if I try to perform indexing using ESH_ADM_INDEX_ALL_SC, not all search connectors are indexed.
I've traced the program ESH_ADM_INDEX_ALL_SC using ST01 transaction code and found these error:
- rscpe__error 32 at rscpu86r.c(6;742) "dest buffer overflow" (,)
- rscpe__error 32 at rscpc (20;12129) "convert output buffer overflow"
- rscpe__error 128 at rstss01 (1;178) "Object not found"
Please kindly help me to solve this issue,
Thank you very much

[svn] 4283: PARB Review changes for Group and DataGroup.
Revision: 4283
Author: [email protected]
Date: 2008-12-10 14:34:18 -0800 (Wed, 10 Dec 2008)
Log Message:
PARB Review changes for Group and DataGroup. The main API changes are:
- content property on Group and FxContainer renamed to mxmlContent.
- contentFactory property on FxContainer renamed to mxmlContentFactory
- New names for DataGroup methods: getRendererForItemAt(index:int):IVisualElement and getItemIndexForRenderer(renderer:IVisualElement):int. These are now in the mxml_internal namespace (not public anymore)
- registerRenderer and unregisterRenderer are private methods (not public)
Also, I made a minor fix to ITransformable.

Check table: V_503_ALL
V_T512Z and V_511_B are the tables for assigment of Permissibility based on ESG and PSA
After creating new EG/ESG (grouping also).
Please note that when we update Employee Group/Subgroup of position in PP01, it is not effective to PF in master data which was maintained with that position & old Employee group/supgroup.
So you should check:
- Position
- PFs with old EG/ESG.
Regards

Multi-column Index vs One index for each column
Hello everyone,
i have one table about 20 000 000 rows, some developers have to generate reports on it and i want to create indexes on this table.
The table has 34 columns, no primary key, no unique keys.
The "where..." clause of the reports usually use 8 columns but some reports uses 8 + some other columns.
can any one help me on what kind of indexes do i have to create?
1. one index for each column used in "where clause"
2. one index for 8 columns and some other indexes for other used columns
3. one index for all columns
or something else etc...

1. one index for each column used in "where clause"
2. one index for 8 columns and some other indexes for other used columns
3. one index for all columns
or something else etc...What's the version of your data base? what kind of database you have, DWH or OTLP? The answer might depend on the type of database as far as bitmap indexes might suit or might not depending if you are runing DWH or OLTP kind of database
Let me suppose that you are runing OLTP database and you have a where clause with 8 columns.
1) are all those where clause equalities (where col1 = and col2 =) or there are inequalities?
2) could you evaluate the most repetitive columns?
3) could you know the column that could have the best clustering factor (the column which most follow a certain order in the table)
Based on that I would suggest to create one b-tree index having 8 columns (even though that it seems for me to high) this index should follow the following points:
1) put the most repetitive column at the leading edge (and compress the index if necessary)
2) put the columns that are used in equalitity predicate first
3) put the column having the best clustering factor first
The most precise index you have the best access you could gain.
Of course that you have to know that an index access is not always good and a FULL table scan is not always bad.
