Separate table and index data in RAC database

Hi Experts,
Our database is Oracle11g RAC database. I need your expertise on this
Do we need to retain the table and index data in two different tablespaces for performance perspective in RAC database too?
Please share your practical experience…Thanks in advance.
Regards
Richard

In my opinion, if there is striping implemented then performance shouldn't degrade even if the index and table blocks are in one tablespace. Exactly.. striping is NOT a good idea at tablespace level as a tablespace is a logical storage device. It is very difficult to stripe comprehensively/correctly at that level, if not impossible.
Striping is a function of the actual storage system and need to happen at physical level. A proper RAID0 implementation.
So the question about multiple tablespaces for a performance increase should not be about striping - but about issues such as data management, block sizes, transportable tablespaces and so on.
Thus my question (at the OP) - what performance problems are expected and are these relevant to the number of tablespaces?

How to create table(s)/indexes on a new database from an existing database

Hello all - I need some help in finishing a task, quick response is really appreciated
So, I have a new database that needs creation of tables including indexes and objects for two different tablespaces called CDS1 and CSD2. I have created these tablespaces and datafiles associated with them. I need some help just to create these tables and indexes from an existing database without copying any of its contents. How can I achieve this, these are 2 different servers at different locations. Can somebody give me step by step instruction - would greatly appreciate it !
Thanks,

Dear All(s)
How i check space used (and number of rows) by each table and index in schema. ( can i check current space utilization and sysdate-date past in time)

Getting a list of all table and index names

Hi,
I have just create a set of tables and indexs, but I have misspelt on of the table names and am now trying to find out what it is. I am using sql*plus as a command line interface but can only find desc as a way of finding any data on a table. What is the command to list all the tables within a table space?
Cheers
Simon

Hi,
there are almost always three ways to find things in Oracle's dictionary :
USER_xxx = thing that you own
ALL_xxx = thing that you own and have access to
DBA_xxx = all things in hole database
If you want to find tables/indexes that you own :
SELECT table_name FROM user_tables
WHERE tablespace_name = 'APP_TBS';
SELECT index_name FROM user_indexes
WHERE tablespace_name = 'APP_TBS';

Missing Tables and Indexes greyed out in DBACOCKPIT

Hi All,
I use Solution Manager 7.01 with MS SQL Server 2008 DB.
I want to monitor with DBACOCKPIT a MS SQL Server 2005 DataBase of a SAP BPC 5.1.
I connected the DB but in DBACOCKPIT some functionality are greyed out.
I want to use in Diagnostics section the "MISSING TABLES AND INDEXES" function but this command is greyed out.
Is it possible to use this function?
Please, help me!
Regards,
Alessandro

Hi,
Gray color means that screen is disabled for any reason (authorization, SQL Server release, monitoring remote, etc).
I believe, those items cannot be monitored unless these limitations are sorted out.
Please refer to the Document "The SAP DBA Cockpit for Microsoft SQL Server" in SDN.
You can get the status about the restriction in the bottom of dbacockpit screen.

DB02 = Missing Tables and Indexes = Unknown objects in ABAP Dictionary = DB views

Hi SAP Gurus,
on our SAP NetWeaver 7.x BW (based on AIX/Oracle) I find via transaction DB02 (path = Diagnostics => Missing Tables and Indexes) under "Unknown objects in ABAP Dictionary" under DB views a BW object /BI0/.....
When I make a double click on the object, I am getting the popup window "Display not possible for this object":
How can I identify the object and clarify with the BW application expert, if needed, how to resolve this object?
I searched already via RSA1 for the object, but I wasn't able to find anything so far ...
Thanks for your help and ideas.
Best regards
Carlos

Hello Carlos
The database view in question is a temporary database object created during a query execution.
Please read this SAP note 449891 - Temporary database objects in BW 3.x to understand what that view is all about and impact if those views are removed.
The SAP notes 449891 and 1139396 suggests to run the report SAP_DROP_TMPTABLES to drop these temporary objects. Whether the objects are still required or not is a question to be put across to the BW team. If the temporary objects are removed when they are used by a query, then the query will fail.
Have a nice day

Import dumpfile with seperate tablespaces for table and index

Hi,
We have a schema for which the its tables are stored in seperate tablespace and indexes are stored in different tablespace. Now we have take full schema export. Now we want to import it on another schema. Now I want to know if the we have difference in the tablespace name we use REMAP_TABLESPACE clause of the impdp command but what about the seperate tablespace for table and indexes. How would Oracle handle this.
Regards,
Abbasi

Hi,
I hope you created the same tablespace structure on the target side if not so remap_tablespace option you have to use for specifying different tablespaces.Oracle will take care of putting data and index.Any how if a index is moved from one tablespace to other you have to rebuild them,once you rebuild them than only stattistics are gathered otherwise you
might face some performance issue.
Better option is to keep same tablespace structures in source and target environment.

BW DB13 Tables and indexes missing

hi, everyone,
our team find a strangethings in DB02 about the growth of table space, there is even no any growth, and it keeps about two months. and then we found that in tables and indexes all table about BW like *ODSD, *FACTD, *DIMD are missing!
I only find DB13C appear the error as" REOGR CHK for All Tables" at the same time .
please tell me why I can't find BW tables ? is there any relations between tables missing and job calendar?
our level is 701, and database is DB6.

It's a fool questions, i found the reason is so easy^^

Transaction DB02 = Missing Tables and Indexes shows under Secondary indexes from package $tmp

Hi SAP Gurus,
I noticed on our SAP business warehouse (BW) system (NetWeaver 7.0 based on AIX/Oracle 11g) in transaction DB02 => Diagnostics => Missing Tables and Indexes under Secondary indexes, 26 indexes, in package $tmp:
The indexes are defined, but they don't have been created on the database.
When I try to create them via the database tool, I am getting the warning:
Does the warning raise up, because they where defined in the $tmp package?
I was looking in SAP notes for a solution for this "warning" concerning the /BIC/F-Indexes but I didn't found yet anything helpful ...
Thanks for your help and ideas ...
Best regards
Carlos

Hi Carlos,
These are secondary indexes created during process chains in BI to improvise performance.
You may refer below SCN blogs on creation of these indices in BI.

Hope this helps.

Create a table and upload data in MS ACCESS from SAP ABAP programming?

Hi All,
How to create a table in MS ACCESS database and Upload SAP database table data into MS ACCESS table using ABAP programming?
Explain: My client requirement is " If he/she runs a ABAP Program, that will create a table and upload data into MS ACCESS Database table in background. "
Could you please give the solution or code? I know the program RIACCESS and I went through the SAP Note 583698.
Is this only solution for this? Or Any other possibilities?
Please give me solution.
Thanks in advance.

Hi,
It is not possible to create tables in a non SAP schema from inside SAP.
The SAP-Oracle license also does not allow you to create the table (see note 581312):
the following actions, among other things, are therefore forbidden at database level:
Creating database users
Creating database segments
Querying/changing/creating data in the database
Using ODBC or other SAP external access methods
Please refer following link,
[Ckick Here|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do]
You can also do it by LSMW,
If you are using Access 97, you can download directly into an access
database from SAP. See program RIACCESS for details. You have to establish
an RFC destination PS_ACCESS_1 and 2.
There are then a couple of function modules. Go to SE37 and put in
msaccess and hit PF4.
The following is from the readme file: sapgui/ps/readme.sap
For the MS-Access interface SAP delivers 4 files:
WDPSASTR.EXE This is an RFC server program that is called by SAP R/3
(PS module). This program creates a MS Access database. The structure
information of the tables is transferred from R/3. In addition to
these tables a table named DDIC is created. This table contains the
structure information and should in no case be modified or deleted.
WDPSATAB.EXE This is an RFC server program that is called by SAP R/3
after WDPSASTR. This program filles the tables of the database with data.
There must not be made any changes of the structure of
the tables between the calls of WDPSASTR and WDPSATAB.
WDPSAZET.EXE This is an RFC client program that triggers work/time
confirmations in the PS module of SAP R/3 (like transaction CN27 Collectiv
confirm).
WDPSAMAT.EXE This is an RFC client program that triggers material
confirmations in the PS module of SAP R/3 (like transaction MB1A - Goods
Please also refer following links,
[Click here|Upload data from MS Access tables, to SAP tables.;
Before using the program "RIACCESS", you need to install the PS utilities, which are part of SAPGUI install CD.
It is available in the "SAPGUIPS directory".
Then do the followings :
1. Select transaction code SALE -> Systems in network-> Define RFC Destination.
2. You will need two RFC destinations (TCP/IP connections for the front-end workstation).
Setup the two RFC destinations PS_ACCESS_1 and PS_ACCESS_2 and you'll have to get them to point to
wdpsastr.exe and wdpsatab.exe respectively.
3. Then execute RIACCESS and choose PS_ACCESS_1 to generate access tables.
The system must also be able to access the RFC-DLL files (librfc2.dll, librfc3.dll, librfc4.dll, librfc5.dll, librfc6.dll, vrfc.dll).
Please note that Access only supports tables with up to 255 fields.

Cannot INSERT records into Partitioned Spatial Table and Index

I am trying to tune our Spatial Storage by creating partitioning our spatial_entity table and index. I used the World Geographic Reference System (GEOREF) creating a partition for each 15 x 15 degree grid square assigning a partition key of decimal longitude, decimal_latitude. The build went OK, however when trying to insert a data record I receive an ORA-14400: Inserted partition key does not map to any partition.

Thank you for your quick reply. I did not post the entire CREATE script as it is quite long. The portion of the script that is applicable to the INSERT is:
,PARTITION p_lt_45e_90s
          VALUES LESS THAN (23, -90)
     ,PARTITION p_lt_45e_75s
          VALUES LESS THAN (23, -75)
     ,PARTITION p_lt_45e_60s
          VALUES LESS THAN (23, -60)
     ,PARTITION p_lt_45e_45s
          VALUES LESS THAN (23, -45)
     ,PARTITION p_lt_45e_30s
          VALUES LESS THAN (23, -30)
     ,PARTITION p_lt_45e_15s
          VALUES LESS THAN (23, -15)
     ,PARTITION p_lt_45e_0
          VALUES LESS THAN (23, 0)
     ,PARTITION p_lt_45e_15n
          VALUES LESS THAN (23, 15)
     ,PARTITION p_lt_45e_30n
          VALUES LESS THAN (23, 30)
     ,PARTITION p_lt_45e_45n
          VALUES LESS THAN (23, 45)
     ,PARTITION p_lt_45e_60n
          VALUES LESS THAN (23, 60)
     ,PARTITION p_lt_45e_75n
          VALUES LESS THAN (23, 75)
     ,PARTITION p_lt_45e_90n
          VALUES LESS THAN (23, maxvalue)
Or, I do not fully understand. Are you indicating that I must explcitly state the longitude in each clause,
e.g ,PARTITION p_lt_45e_45n
          VALUES LESS THAN (45, 45)
,PARTITION p_lt_45w_45n
          VALUES LESS THAN (-45, 45)
If so, that answers the question of why it cannot find a partition, however an Oracle White Paper "Oracle Spatial Partitioning Best Practices" Sept 2004, discusses multi column partitioning such as represented by this problem, and gives an INSERT statement example of :
CREATE TABLE multi_partn_table (in_date DATE,
geom SDO_GEOMETRY, x_value NUMBER, y_value NUMBER)
PARTITION BY RANGE (X_VALUE,Y_VALUE)
PARTITION P_LT_90W_45S VALUES LESS THAN (1,-45),
PARTITION P_LT_90W_0 VALUES LESS THAN (1,0),
PARTITION P_LT_90W_45N VALUES LESS THAN (1,45),
PARTITION P_LT_90W_90N VALUES LESS THAN (1,MAXVALUE
and as I am writing this I am seeing that I failed to include the longitude and latitude in the SDO_GEOMETRY clause, so it does appear tht I need to explicitly state the longitude valuues.
What is your judgement sir?

Fragmentation in tables and indexes with 9.2.0.5

Hi guys ,
I need of query to identified fragmentation in tables and indexes using Oracle 9i,someone could help me send that's querys
tks
spaulonci

Fragmentation by itself at the tablespace level doesn't mean any thing from the performance point of view, only from the storage capacity perspective, and this just in case fragments are not necessarily the same size as in the case of dictionary manged tablespaces.
You may be concerned about block density, which actually could lead to performance degradation. I suggest you to consider using coalesce instead of rebuilding in the case of indexes, and in the case of tables you should perform a segment reorganization. In the case of 9iR2 the coalesce command for table segments is not available so you will have to perform another segment reorganization strategy. If there are meaningful differences with the high water mark, average number of rows per block and chained rows then you will notice performance differences.
I suggest you to take metrics for block usage prior to perform an index coalesce operation, as well as prior to perform a data segment reorganization to assess if the reorganization effort is useful.
