0BWTC_C02 BW Statistics - OLAP: Obsolete in 7.0
Hi All
We have recently upgraded but not the BI cockpit yet (problems setting it up).
We want to reprt on things that were in the 0BWTC_C02 but this no longer collects data.
Is there a way to report on this without having set up the new BI cockpit like does the data sit anywheere else or must we set up the cockpit.
Cheers
Andy
Hi Andy,
For more Insights -
The new InfoProviders are:
For more highly aggregated query-runtime statistics:
0TCT_C01, 0TCT_VC01 and 0TCT_MC01
These replace InfoCube 0BWTC_C02.
For more detailed query-runtime statistics:
0TCT_C02, 0TCT_VC02 and 0TCT_MC02
These replace InfoCube 0BWTC_C02.
For data manager statistics:
0TCT_C03, 0TCT_VC03 and 0TCT_MC03
These replace InfoCube 0BWTC_C03.
For data-load statistics of process chains and processes:
0TCT_C21, 0TCT_VC21 and 0TCT_MC21
For data-load statistics of data transfer processes:
0TCT_C22, 0TCT_VC22 and 0TCT_MC22
For data-load statistics of InfoPackages:
0TCT_C23, 0TCT_VC23 and 0TCT_MC23
These deliver essentially the same information as InfoCube 0BWTC_C05 but they use the new InfoObjects. The remaining new InfoProviders also use the new InfoObjects.
For the current data-load status of process chains and processes:
0TCT_VC11 and 0TCT_MC11
For the current status of requests loaded to InfoProviders, InfoObjects that have been updated flexibly, and PSA tables:
0TCT_VC11 and 0TCT_MC11

Anil

0bwtc_c02 (BW statistics)
Hi,
Kindly let me know in the cube 0bwtc_c02 (BW statistics) which charac/key figure tells us who and when a query was last
used(not modified)
Or in which cube can I find this info (we are using BW3.5 version )
Regards,
dolaHi,
You should be able to use the infocube 0BWTC_C02 and the use the fields:
0TCTUSERNM (user name)
0TCTQUERY (query name)
0TCTTIMSTMP (timestamp)
For more information, check:

BW Statistics - OLAP Navigations
I am interested in getting stats out of the stats cube that show the number of times a query is executed. OLAP navigations include this but also include things such as drilldowns and filtering. Is there any way of getting just the number of times a query is executed out of the stats cube such as a key figure that I havn't found?
Any help much appreciatedHi Ian !
To determine how often a query is called, at best use a calculated key figure. The calculated key figure refers to key figure 0TCTSTAUIK. Define an exception aggregation of type count. The following reference characteristics are possible for exception aggregation:
a) 0TCTSESUID - Determines the number of times a query is called.The number of navigations is not taken into account.
b) 0TCTNAVUID - Determines the number of navigations.
Hope it helps !

BW Statistics and Technical Content
HI,
I am working on BI 7.0.
I understand both BW statistics and Technical content are used to monitor the system status to improve performance. But what I dont get is teh exact difference between these two.
BW statistics provides the follwing Dataprovider:
0BWTC_C02 BW Statistics - OLAP
0BWTC_C03 BW Statistics - OLAP, Detail Navigation
0BWTC_C04 BW Statistics - Aggregates
0BWTC_C05 BW Statistics - WHM
0BWTC_C09 BW Statistics: Condensing InfoCubes
0BWTC_C11 BW Statistics: Deleting Data from InfoCubes
Whereas Technical content provides following:
0TCT_C03 Data Manager Statistics (Details)
0TCT_C22 DTP Statistics
0TCT_C01 Front End and OLAP Statistics (Aggregated)
0TCT_C02 Front End and OLAP Statistics (Details)
0TCT_C23 Infopackage Statistics
0TCT_C21 Process Chain Statistics
Please advice
Regards
PankajThanks...
but in the following link of 7.0 saphelp, it still shows the BW statistics cube 0BWTC* and so is the confusion whether to use 0BWTC* also aprt from using 0TCT*

Welcome to SDN
We use BW statistics to evaluate the fundamental functional areas of the Business Information Warehouse.
BW statistics provides you with the following options that allow you to evaluate data from both the OLAP processor and warehouse management. You are able to
· get an overview of how InfoProviders, InfoObjects, InfoSources, source systems, queries, and aggregates are used
· determine the system performance and improve it
· improve the way in which aggregates are selected and used and reduce the cost of updating them
Please check these threads

Some of the Statistic Cubes are
0BWTC_C05 BW Statistics - WHM
0BWTC_C04 BW Statistics - Aggregates
0BWTC_C02 BW Statistics OLAP

Hi all,
We have different installation, R/3 4.6C, BW3.5, BW 310c, CRM 4.0...and my question is about the transaction DB13 for daily DB check, the result based on configured table in DBSTATC, the system doesn't detect others tables with obsolete statistics, so, I've my own process that I start and this process is like DB20 doing a refresh and computing the difference in %, and after this I use the list to compute the statistics. So, do you think there's a way to locate those obsolete statistics ?Hi Fidel,
When during a process there's many operations like delete/insert/update on a table (for example srrelroles on CRM env.), you can start from DB13 a DBCHECK and the result is OK, green, because this table in not in the configuration table for statistics (DBSTATC), but when you start TR DB20 and you enter table name and refresh, the system compute a deviation, and if this deviation is greater than 50%, the system give you a message "statistics are obsolete" and to solve this, you have to compute/estimate the statistics. Hope this help you.

BW Statistics 0BWTC_C10 in BW 3.5
We have the BW Stats multi cube(0BWTC_C10) which currently consists of six cubes.
1. BW Statistics OLAP 0BWTC_C02
2. BW Statistics - OLAP, Detail Navigation 0BWTC_C03
3. BW Statistics - Aggregates 0BWTC_C04
4. BW Statistics - WHM 0BWTC_C05
5. BW Statistics: Condensing InfoCubes 0BWTC_C09
6. BW Statistics: Deleting Data from InfoCubes 0BWTC_C11
We have the data in all except 0BWTC_C02
Now I want to load the data in to it and want to develop some queries on the MultiProvider(0BWTC_C10)
Can any one help me in how to load the data to 0BWTC_C02??
Any help much appreciated.
Kind Regards,
BHHi Sesh,
1)
0BWTC_C02 is replaced by 3 cubes: 0TCT_MC01, 0TCT_MC02 and 0TCT_MC03
(here each mulitprovider is based on 2 cubes, one basic cube and one virtual cube.
For ex, 0TCT_MC01 has basic cube 0TCT_C01 and virtual cube 0TCT_VC01, the naming convention is same for rest 0TCT_C* and 0TCT_VC*)
Hope the above is clear
0BWTC_C03 was referring to RSDDSTAT table before, but this table has become obsolete in BI 7.0. Corrections have made to the extractor in BI 7.0 SAP_BW SP 9 such that the extractor refers to RSDDSTAT_OLAP. So you can use this cube as the way you were using in BW 3.x if you are above or equal to SP 9.
0BWTC_C04 - no migration is required, technical content 3.x is still valid.
0BWTC_C05 - is replaced by 0TCT_MC23 (0TCT_C23 and 0TCT_VC23)
0BWTC_C09 - no migration is required, technical content 3.x is still valid.
0BWTC_C11 - no migration is required, technical content 3.x is still valid.
2) There is virtual provider for all the replaced cubes, but the old cubes for which migration is not required dont have virtual cubes.
3) The new multiproviders have virtual cubes alreday.
Hope this helps.

Best practices for gathering statistics in 10g
I would like to get some opinions on what is considered best practice for gathering statistics in 10g. I know that 10g has auto statistics gathering, but that doesn't seem to be very effective as I see some table stats are way out of date.
I have recommended that we have at least a weekly job that generates stats for our schema using DBMS_STATS (DBMS_STATS.gather_schema_stats). Is this the right approach to generate object stats for a schema and keep it up to date? Are index stats included in that using CASCADE?
Is it also necessary to gather system stats? I welcome any thoughts anyone might have. Thanks.Hi,
Is this the right approach to generate object stats for a schema and keep it up to date? The choices of executions plans made by the CBO are only as good as the statistics available to it. The old-fashioned analyze table and dbms_utility methods for generating CBO statistics are obsolete and somewhat dangerous to SQL performance. As we may know, the CBO uses object statistics to choose the best execution plan for all SQL statements.
I spoke with Andrew Holsworth of Oracle Corp SQL Tuning group, and he says that Oracle recommends taking a single, deep sample and keep it, only re-analyzing when there is a chance that would make a difference in execution plans (not the default 20% re-analyze threshold).
I have my detailed notes here:
http://www.dba-oracle.com/art_otn_cbo.htm
As to system stats, oh yes!
By measuring the relative costs of sequential vs. scattered I/O, the CBO can make better decisons. Here are the data items collected by dbms_stats.gather_system_stats:
No Workload (NW) stats:
CPUSPEEDNW - CPU speed
IOSEEKTIM - The I/O seek time in milliseconds
IOTFRSPEED - I/O transfer speed in milliseconds
I have my notes here:
http://www.dba-oracle.com/t_dbms_stats_gather_system_stats.htm
Hope this helps. . . .

BI: How many bytes consumes an Infocube or DSO in Database
Hi Colleagues,
is there an easy way, to find out, how many MB an Infocube or an DSO consumes actually on DB.
Thanks ans regards,

Frontend Trend Monitoring - Monthly trends for queries
I am currently working on a front end, to get result for the Top 10 Worst Performing Queries.
I need to get the query for each and every month as per the user specification, in a Descending order for every month.
I think, it is not possible to get the results for all the queries, for all the months at one go.
Please let me know, if it is possible.
The important thing is that, I need to present the above obtained data, in a graphical manner, for trend analysis.Hello Hitesh,
Better to install Technical Business content, BW Statistics - 0BWTC_C10 is the multiprovider . To get reports on queries you can install 0BWTC_C03 cube- BW-Statistics OLAP,Detail Navigation.
Hope this gives you some idea....

RSRV: Oracle statistics info table for table /BIC/FCube1 may be obsolete
Hi,
I run RSRV on cube1 and got several yellow lines such as:
Oracle statistics info table for table /BIC/FCube1 may be OBSOLETE
Oracle statistics info table for table /BIC/SSalesOrg may be OBSOLETE
Oracle statistics info table for table /BIC/DCube1P may be OBSOLETE
DB statistics for Infocube Cube1 must be recreated.
I read here on SDN that running Correct Error in RSRV is only a temporay fix and that the best solution is to fix it from the database level with BRCONNECT.
But the DBA says she has already run BRCONNECT yet there was no change in these several of the lines which came out as Yellow. ... still same OBSOLETE messages.
1. Any additional sugestions to fix these problems at the database level?
2. In case I decide to fix with Correct Error in RSRV, what issues can I encounter with the cube?
Can this lead to a failure of the cube?
Will users encounter any issues with report?
Does fixing the OBSOLETE in the error message in RSRV have any hazzards?
ThanksHi,
it is years of data but how do you decide that the data is huge to warrant creating a new cube?
You noted that
"verify if it makes sense to copy the data into a new cube "
How do I verify that?
Is creating a new cube the only solution to this OBSOLETE problem?
Why is it referring to only particular tables as OBSOLETE and doesn't that indicate that this is not a problem with the overall cube?
Thanks -
OLAP Statistics table RSDDSTAT is locked
I am working on BW 3.1C and my issue is:
The OLAP Statistics table RSDDSTAT is locked due to some data base rollback activities. When users execute the query, it is first hitting the statistics table and since it is already locked, I am getting -913 sql short dumps. In order to avoid this, I have used the following option:
RSA1 --> Tools --> BW Statistics for Infoprovider.
I have unchecked all data targets. When I ran the query in RSRT/RSRT2, the query gets successfully executed without hitting the statistics table.
But when I tried to execute the query from Web, it is hitting the statistics table which again causing me short dumps. Is there any Tcode where I can turn-off the statistics settings. Please mention that I am in 3.1C version and do not have T.code RSDDSTAT.
Please let me know how to resolve this issue?Hi,
In BI 7 there's a table RSDDSTATOBJLEVEL which we can decide record statistics or not.. Can you try to whether it exist in your machine? I don't have BW 3.x system at hand.
