In - DB13 - warnings for missing indexes

Hi
I've noticed in the results of the DBCHECK job in DB13 that we have a number of warnings for missing indexes.
BR0970W Database administration alert - level: ERROR, type: MISSING_INDEX, object: (table) SAPR3./BI0/PCOSTELMNT
The strange thing is that no missing indexes are picked up be DB02. In SE11 these tables cannot be found. Checked at Oracle level and the tables exist but the indexes do not.
Does anyone know if these tables should have indexes?
If so what would be the best way to create these?
Thanks & Regards
Shishir

In DB02 they are probably showing under 'Optional Indexes' under 'not created'

Check Missing Indexes

Hi All,
We have a Database with many tables using foreign keys. Some of my queries from coldfusion are slow. We are using 11g version.
It's a way to check for missing indexes?
I would like to help the database to perform better, I know this is a huge topic but as new in oracle I need to start somewhere.
Any links or comments will be appreciate it.
Regards
Johnny

i have created a two step process for finding which Foreign key is not indexed
1. create a table having the ddl of all indexes
CREATE TABLE INDEX_TXT_TBD AS
SELECT DBMS_METADATA.GET_DDL('INDEX',INDEX_NAME) TXT FROM USER_INDEXES WHERE INDEX_TYPE='NORMAL' AND INSTR(INDEX_NAME,'$') = 0
2. create a table which will tell the tablename, columnname (FK) who are not indexed
CREATE TABLE INDEX_TBD AS
select distinct
     user_cons_columns.TABLE_NAME,
     user_cons_columns.COLUMN_NAME
from
     user_cons_columns,
     user_constraints,
     INDEX_TXT_TBD,
where
     user_constraints.CONSTRAINT_NAME=user_cons_columns.CONSTRAINT_NAME
     and CONSTRAINT_TYPE='R'
     AND INSTR(TXT,'"' || user_cons_columns.TABLE_NAME || '" ("' || user_cons_columns.COLUMN_NAME || '")') = 0

Hi,
these looks like active tables of ODS/DSOs...
You position you cursor on the missing object in DB02 and hit the create in DB button; better choose in background.
Note that they will remain showing missing in DB02 until statistics are refreshed...
After the background jobs are completed hit the dsplay definition button; you will be lead to the SE14 screen for this IDX; it should say that the index exists in the DB;
Tomorrow your DB02 screen should be updated...
hope this helps...

Hi All,
Just an update, I was able to get around my problems by patching the 2004s media from sp6 to sp8, uninstalling my scs, and database and re-installing from the patched media.

DB statistic missing & Missing index for critical tables after TDM refresh

Hello SAP expert,
We have completed our refresh using TDM, but after the refresh we encounter problem at the receiver system,
Issue Encounter
1. System too slow
2. When running tcode it resulted to time_out dump
3. Db statistics are missing
4. missing index for critical tables
Appreciate your help. How can we check tdm log if the data transfer really transferred or completed succesfuly.
Thanks

Thanks for your reply.
We are looking the possible root cause of the issue, everything is fine in the target system before the refresh even the DB statistics update job is working fine before the refresh.
is there a way we could find logs or report from tdms server if there something happen during the execution of the tdm jobs or data selection and transfer. as we only find logs of the latest run. let say we execute the data transfer 4 times where we could find a report or logs stating the error or execution logs from the 2nd or on 3rd run?
thanks

Missing indexes after system copy

Hi All
we have around 70,000 missing indexes after the system copy
offline export from
source with sun solaris oracle
To
Linux oracle
but these appeared after we Run SGEN , which took 60 hours for a 200 Gb database.
and target system response is also slow , how to go ahead with this issue
we have checked export and import logs , none of the packages were missed
1 Why these missing indexes after SGEN , and why SGEN for 60 hours
2 when we check the Tables which appeared in Missing indexes ,from SE14 it says In Consistency with Data dictionary
3 and the other error , is Index Missing in the database ,
4 but we cant create all these manually.
Regards

Hi Matt
Thanks for the response
After sap suggestion , we have done only import again, with 721 R3load same as export.
but still the R3load.exe.log of import shows as done with 720 kernel.
import R3load.exe log //bas/720_REL/src/R3ld/R3load/R3ldmain.c#
export R3load.exe log //bas/721_REL/src/R3ld/R3load/R3ldmain.c#10 $ SAP
But when we compare the sapinst_dev and AGR logs both from export and import
both are referring the same 721 R3load version ,
//bas/721_REL/src/R3ld/R3load/R3ldmain.c
still we have same missing indexes issue , after we did the import again.
Are we making any mistakes in export , Any suggestions are welcome
hi all , kindly respond with your inputs , on this

Missing Indexes in Database

Hi,
In tcode DB02, when seeing database statistics, i found that there were some missing indexes in database. ie., for some tables there are no indexes created.
Please tell me whether we need to create indexes or not. Is there any serious effect of a table not having any index?
Please suggest me a good solution for this.
Thanks,
Sailesh K

Not necessarily. You must decide if an index will assist in making a table scan faster. FULL table scans indicate that an index is not available. Creating an index in this case, will improve preformance and prevent full table scans from occuring.
Also, check oracle to see if the index exists. Somestimes the Data Dictionary is unaware of the index due to how it ws created.
In summary missing indexes are not a problem. FULL table scans are problems and require new indexes to be created for performance reasons.
Hope this helps.

Missing index problem

Hi Gurus!
I have a critical problem to solve.
I have a table without data which is inconsistent because it doesn't have the primary index. When i see missing indexes at DB02, the system tells me that the index is created, but when i go to SE14 and select the primary index, it says the index does not exists on the database and the only option that is active is the one to create the index. If I try to create the index, i get an error saying: there is already a an object named 'zmed_distr~0' ( my index name ).
Can anybody help me?
Thank you in advance.

the tsystem does'nt create the index and give me this log:
Request: Create Index ZMED_DISTR-0 (FORM05/11.12.07/19:06)
Process: BLADE04_0
sql:
ALTER TABLE [ZMED_DISTR]

PRIMARY KEY CLUSTERED
( [MANDT] ,
[ZUONR] ,
[GJAHR] ,
[KUNNR] ,
[ESTAB] ,
[TXT20] ,
[REPS] )
There is already an object named 'ZMED_DISTR~0' in the database.Could
not create constraint. See previous errors.
DDL time(___1): .........3 milliseconds
The SQL statement was not executed
Index   could not be created completely in the database
Index ZMED_DISTR-0 could not be created

Creating Missing Indexes

I find a missing Index when I do Database check
This is the error message:
"BR970W Database administration alert - level: ERROR, type: MISSING_INDEXES, object: (table) SAPR3.ZGMM0015"
I executed Trx. DB02 - Missing Indexes - there I find
--> Index missing under database
    --> primary index - 1
      --> Z..... --> I selected this and clicked on "Create in DB".
   Then it pops up a dialog box asking options like Online, Background .... (can I create this Index online)
   from here what I needs to do.
Gurus can some one guide me.
Thanks in advance

Looks like index is missing for the table.. When you get options like online, background, you may use online. It does not hamper the system.

Generated index is missing indexed items

Working with book and separate chapter for index. Index generates but is missing index entries. Is it something I'm doing or an InDesign problem?

Thanks for input. All available updates have been applied. Long telcon with India so far has produced no cure but at last they are 'escalating' problem to find a solution. It seems to only happen in the 'Symbols' heading (non-alphabetic entries) of the index. Not only are items missing but reference page numbers are missing and/or scrambled. Looks like several indexed subjects are loosing page references and/or picking up page references from following index lines. If you can read the image attached you'll see what I'm talking about if you compare the index flyout lines with what shows up in the generated index. Quite a time consuming pain. It took me almost an hour on the phone to get India to the point they wanted to see this.

Missing indexes found in DB02

Respected All,
We found a huge number of missing indexes(primary and secondary both) in DB02.Is there any way to rebuilt or produce all these missing indexes in a mass or in a single step?? Thanks in advance for your supports

Dear,
You can create indexes as per your requirement. You can create by BRTOOLS as well as from SE14 t-code. After creating index you have to run Update statastics job.

Missing indexes in db02

Hello,
Checking DB02 i've found a list of missing primary indexes. I know that i can use SE14 to adjust the indexes but i found some decumentation that says that i should first check if double index for the primary index exist and elimenate them.
Please Advice.
David.

hi David,
oss note 157918
BW: DB02 shows "missing indexes"
Symptom
DB02 shows indexes of a fact table to be missing. Such indexes have names that start with prefixes /BI0/F or /BIC/F (BW 1.2, BW 2.x) or /BI0/E or /BIC/E (BW 2.x only).
Additional key words
Business Information Warehouse, InfoCube, Fact Table, Bitmap Indexes, Oracle, DB02, Unique Index
Cause and prerequisites
For BW 1.2, this only applies to Oracle-based systems. For BW 2.x, this might apply to any DB-platform.
BW 1.2 and BW 2.x take advantage of certain DB-specific features which are not supported by the data dictionary of R/3 4.0, 4.5 or 4.6 base systems. Prominent examples are bitmap indexes on fact tables (Oracle-based BW systems), partitioned/fragmented indexes, nologging and parallel index building facilities etc. Such features are used in BW by triggering native SQL statements which bypass the data dictionary.
While all these features improve performance of the BW system, there are, however, some other transactions that are also affected when the data dictionary is bypassed. Amongst these is DB02. It sometimes claims that certain indexes of infocube fact tables are missing while direct checks on the database level show that those indexes are not missing at all or substituted by equivalent indexes. The latter might happen in BW 2.x where the primary index on fact tables might be replaced by a non-unique index or simply skipped as it is not required. Therefore you can usually ignore those messages. Obviously, we are currently working on removing such inconsistent information. If you want to be sure on the indexing then check the solution section of this note.
Solution
For BW 1.2A systems (Oracle only):
You have to ask your local DBA to check the state of the indexes directly by looking at the USER_INDEXES table on the Oracle database.
For BW 1.2B systems (Oracle only):
There are two alternatives to check the secondary indexes of infocube and aggregate cubes fact tables:
           (1) Go to the Admin Workbench. Go to the infocube. Click the right mouse button and choose "InfoCube Performance". This leads you to a screen that shows the state of those indexes via traffic light semantics. There are also buttons to repair inconsitent states of the indexes.
           (2) Use transaction RSRV. Go to the tabstrip "Database". Choose the item "Indices of an InfoCube and its aggregates" and insert the (technical) infocube name (e.g. 0BWTC_C01) in the input box at the bottom of the screen. Press F8 ("Analysis") and wait until a red, yellow or green light appears beside "Indices of an InfoCube and its aggregates", i.e. in the "Result" column. Then press F6 ("Results") in order to see a detailed report on the index situation of that cube.
           (3) Go to SE37 and do a "single test" for the function module RSDU_CHECK_SECONDARY_INDEXES. Use the infocube's technical name (e.g. 0BWTC_C01) as the input parameter and 'X' for both, the I_COMPLETE_CHECK and I_WITH_AGGREGATES, parameters. Press F8 to run the module. Only the C_T_INDEX output parameter is relevant. It shows a list of indexes. Check the TYPE and STATUS columns. These should show 'BITMAP' and 'VALID' respectively.
For BW 2.0A systems (all DB-platforms):
For checking secondary indexes on individual infocubes the following methods can be applied, similar to the BW 1.2B solution:
           (1) Go to the Admin Workbench. Go to the infocube. Click the right mouse button and choose "Manage". Choose the tabstrip "Performance". This leads you to a screen that shows the state of those indexes via traffic light semantics. There are also buttons to repair inconsitent states of the (secondary) indexes.
           (2) same as (2) for BW 1.2B.
           (3) Go to SE37 and do a "single test" for the function module RSDU_INFOCUBE_INDEXES_CHECK. Use the infocube's technical name (e.g. 0BWTC_C01) as the input parameter, leave the I_FACTTAB initial, use 'X' for both, the I_COMPLETE_CHECK and I_WITH_AGGREGATES, parameters and use 'U' in the I_DOUBLE_FACTTAB parameter. Press F8 to run the module. Only the C_T_INDEX output parameter is relevant. It shows a list of indexes. Check the TYPE_CHECK, UNIQUE_CHECK, PARTITIONED_CHECK and STATUS_CHECK columns. These should show 'G' (= "green" = ok) respectively.
If your BW 2.0A system is on patch level 11 Make DB02 consistent by running the report SAP_UPDATE_DBDIFF (via SE38), go to DB02 and press the "Refresh" button in order to synchronise the information in DB02 with the DBDIFF table. This should provide you with a consistent view.
For BW 2.0B and BW 2.1C systems (all DB-platforms):
DB02 should work consistently in BW 2.0B / BW 2.1C with infocubes created in 2.0B / BW 2.1C. If you wish, you can still use the BW 2.0A approach. For infocubes that were created in BW 2.0A or BW 1.2 you need to adjust the index setup (on the facttables) by running the report SAP_INFOCUBE_INDEXES_REPAIR. The latter is available from BW 2.0B patch 3 onwards. It should be run in a background process as it might take a while to run through.
You also might want to run the report SAP_UPDATE_DBDIFF once in order to update the table DBDIFF that lists database objects whose data dictionary setting do not correspond to the actual setup and that should therefore be omitted in DB02 checks.
