Performance issues with data warehouse loads

We have performance issues with our data warehouse load ETL process. I have run
analyze and dbms_stats and checked database environment. What other things can I do to optimize performance? I cannot use statspack since we are running Oracle 8i. Thanks
Scott

Hi,
you should analyze the db after you have loaded the tables.
Do you use sequences to generate PKs? Do you have a lot of indexex and/or triggers on the tables?
If yes:
make sure your sequence caches (alter sequence s cache 10000)
Drop all unneeded indexes while loading and disable trigger if possible.
How big is your Redo Log Buffer? When loading a large amount of data it may be an option to enlarge this buffer.
Do you have more then one DBWR Process? Writing parallel can speed up things when a checkpoint is needed.
Is it possible using a direct load? Or do you already direct load?

Performance issues with Planning data load & Agg in 11.1.2.3.500

We recently upgraded from 11.1.1.3 to 11.1.2.3. Post upgrade we face performance issues with one of our Planning job (eg: Job E). It takes 3x the time to complete in our new environment (11.1.2.3) when compared to the old one (11.1.1.3). This job loads then actual data and does the aggregation. The pattern which we noticed is , if we run a restructure on the application and execute this job immediately it gets completed as the same time as 11.1.1.3. However, in current production (11.1.1.3) the job runs in the following sequence Job A->Job B-> Job C->Job D->Job E and it completes on time, but if we do the same test in 11.1.2.3 in the above sequence it take 3x the time . We dont have a window to restructure the application to before running Job E every time in Prod. Specs of the new Env is much higher than the old one.
We have Essbase clustering (MS active/passive) in the new environment and the files are stored in the SAN drive. Could this be because of this? has any one faced performance issues in the clustered environment?

Do you have exactly same Essbase config settings and calculations performing AGG ? . Remember something very small like UPDATECALC ON/OFF can make a BIG difference in timing..

Performance issues with Homesharing?

I have a Time Capsule as the base station for my wireless network, then 2 Airport Express setup to extend the network around the house, an iMac i7 as the main iTunes Library and couple of iPads, and a couple of Apple TVs. Everything has the latest software, but I have several performance issues with Home sharing. I've done several tests making sure nothing is taking additional bandwidth, so here are the list of issues:
1) With nothing else running, trying playing a movie via home sharing in an iPad 2 which is located on my iMac, it stops and I have to keep pressing the play button over and over again. I typically see that the iPad tries to download part of the movie first and then starts playing so that it deals with the bandwidth, but in many cases it doesn't.
2) When trying to play any iTunes content (movies, music, photos, etc) from my Apple TV I can see my computer library, but when I go in on any of the menus, it says there's no content. I have to reboot the Apple TV and then problem fixed. I's just annoying that I have to reboot.
3) When watching a Netflix movie on my iPad and with Airplay I send the sound to some speakers via Airplay through an Airport Express. At time I lose the connection to the speakers.
I've complained about Wifi's instability, but here I tried to keep everything with Apples products to avoid any compatibility issues and stay within N wireless technology, which I understood it was much more stable.
Has anyone some suggestions?

Performance issues with 0CO_OM_WBS_1

We use BW3.5 & R/3 4.7 and encounter huge performance issues with 0CO_OM_WBS_1? Always having to do a full load involving approx 15M records even though there are on the average 100k new records since previous load. This takes a longtime.
Is there a way to delta-enable this datasource?

Hi,
This DS is not delta enabled and you can only do a full load. For a delta enabled one, you need to use 0CO_OM_WBS_6. This works as other Financials extractors, as it has a safety delta (configurable, default 2 hours, in table BWOM_SETTINGS).
What you should do is maybe, use the WBS_6 as a delta and only extract full loads for WBS_1 for shorter durations.
As you must have an ODS for WBS_1 at the first stage, I would suggest do a full load only for posting periods that are open. This will reduce the data load.
You may also look at creating your own generic data source with delta; if you are clear on the tables and logic used.
cheers...

Performance Issue with RF Scanners after SAP Enhancement Pack 5 Upgrade

We are on component version SAP ECC 6.0, and recently upgraded to Enhancement Pack 5. I believe we are on Net Weaver 7.10, and using RF scanners in one plant that is Warehouse Managed. Evidentially when we moved to EHP5, the Web SAP Console went away and we are left with ITS Mobile. This has created several issues and continues to be a performance barrier for the forklift drivers in the warehouse. We see there is a high use of java script, and the processors canu2019t handle this. When we login to tcode LM00, on a laptop or desktop computer, there are no performance issues. When we login to tcode LM00, with the RF scanners, the system is very slow. It might take 30 seconds to confirm one item on a WM Transfer Order.
1.) Can we revert back to Web SAP Console, after we have upgraded to EHP5?
2.) What is creating the performance issues with the RF Scanners now that we switched over to SAP ITS mobile?
Our RF Scanners are made by Intermec, but I donu2019t think that is where the solution lies. One person in our IT Operations has spent a good deal of time configuring SAPITS to get it to work, but still it isnu2019t performing.

Tom,
I am sorry I did not see this earlier.
I'm currently working on a very similar project with ITS mobile and the problem is to accurately determine the root cause of the problem in the least amount of time. The tool that works is found here: http://www.connectrf.com/index.php/mcm/managed-diagnostics/
Isolating the network from the application and the device is a time consuming process unless you have a piece of software that can trace the HTTP transaction between host and device on both wired and wireless side of the network. Once that is achieved (as with Connect's tool) you can then you can begin to solve the problem.
What I found in my project is that the amount of data traffic generated by ITS mobile can be reduced drastically, which speeds the response time of the mobile devices, especially with large number of devices in distribution centers.
Let me know if I can answer more questions related to this topic.
Cheers,
Shari

Performance issues with query input variable selection in ODS

Hi everyone
We've upgraded from BW 3.0B to NW04s BI using SP12.
There is a problem encountered with input variable selection. This happens regardless of using BEx (new or old 3.x) or using RSRT. When using the F4 search help (or "Select from list" in BEx context) to list possible values, this takes forever for large ODS (containing millions of records).
Using ST01 and SM50 to trace the code in the same query, we see a difference here:
NW04s BI SQL command
SELECT
"P0000"."COMP_CODE" AS "0000000032" ,"T0000"."TXTMD" AS "0000000032_TXTMD"
FROM
( "/BI0/PCOMP_CODE" "P0000" ) LEFT OUTER JOIN "/BI0/TCOMP_CODE" "T0000" ON "P0000"."COMP_CODE" = "T0000
"."COMP_CODE"
WHERE
"P0000"."OBJVERS" = 'A' AND "P0000"."COMP_CODE" IN ( SELECT "O"."COMP_CODE" AS "KEY" FROM
"/BI0/APY_PP_C100" "O" )
ORDER BY
"P0000"."COMP_CODE" ASC#
BW 3.0B SQL command:
SELECT ROWNUM < 500 ....
In 3.0B, rownum is limited to 500 and this results in a speedy, though limited query. In the new NW04s BI, this renders the selection screen unusable as ABAP dumps for timing out will occur first due to the large data volume searched using sequential read.
It will not be feasible to create indexes for every single query selection parameter (issues with oerformance when loading, space required etc.). Is there a reason why SAP seems have fallen back on a less effective code for this?
I have tried to change the number of selected rows to <500 in BEx settings but one must reach a responsive screen in order to get to that setting and it is not always possible or saved for the next run.
Anyone with similar experience or can provide help on this?

here is a reason why the F4 help on ODS was faster in BW 3.x.
In BW 3.x the ODS did not support the read mode "Only values in
InfoProvider". So If I compare the different SQL statements I propose
to change the F4 mode in the InfoProvider specific properties to
"About master data". This is the fastest F4 mode.
As an alternative you can define indexes on your ODS to speed up F4.
So would need a non-unique index on InfoObject 0COMP_CODE in your ODS

Performance issues with pipelined table functions

I am testing pipelined table functions to be able to re-use the base_query function. Contrary to my understanding, the with_pipeline procedure runs 6 time slower than the legacy no_pipeline procedure. Am I missing something? The processor function is from [url http://www.oracle-developer.net/display.php?id=429]improving performance with pipelined table functions .
Edit: The underlying query returns 500,000 rows in about 3 minutes. So there are are no performance issues with the query itself.
Many thanks in advance.

Like:
- a database version
- how did you test
- what data do you have, how is it distributed, indexed
and so on.
If you want to find out what's going on then use a TRACE with wait events.

Performance issues with the Vouchers index build in SES

Hi All,
We are currently performing an upgrade for: PS FSCM 9.1 to PS FSCM 9.2.
As a part of the upgrade, Client wants Oracle SES to be deployed for some modules including, Purchasing, Payables (Vouchers)
We are facing severe performance issues with the Vouchers index build. (Volume of data = approx. 8.5 million rows of data)
The index creation process runs for over 5 days.
Can you please share any information or issues that you may have faced on your project and how they were addressed?

Check the following logs for errors:
1. The message log from the process scheduler
2. search_server1-diagnostic.log in /search_server1/logs directory
If the build is getting stuck while crawling then we typically have to increase the Java Heap size for the Weblogic instance for SES>

Performance issues with Bapi BAPI_MATERIAL_AVAILABILITY...

Hello,
I have a Z program to check ATP which is working with Bapi BAPI_MATERIAL_AVAILABILITY....
As I am in the retail system we have performance issues with this bapi due the huge amount of articles in the system we need to calculate the ATP.
any way to improve the performance?
Thanks and best regards
L

The BAPI appears to execute for only one plant/material, etc., at a time, so I would have to concentrate on making data retrieval and post-bapi processing as efficient as possible. In your trace output, how much of your overall time is consumed by the BAPI? How much by the other code? You might find improvements there...

Hello Vitor,
There are currently no known issues with version enabled tables that are partitioned. The merge operation may need to access all of the partitions of a table depending on the data that needs to be moved/copied from the child to the parent. This is the reason for the 'Partition Range All' step in the plan that you provided. The majority of the remaining steps are due to the hints that have been added, since this plan has provided the best performance for us in the past for this particular statement. If this is not the case for you, and you feel that another plan would yield better performance, then please let me know and I will take a look at it.
One suggestion would be to make sure that the table was been recently analyzed so that the optimizer has the most current data about the table.
Performance issues are very hard to fix without a reproducible test case, so it may be advisable to file a TAR if you continue to have significant performance issues with the mergeWorkspace operation.
Thank You,
Ben

Performance issues with SAP BPC 7.0/7.5 (SP06, 07, 08) NW

Hi Experts
There are some performance issues with SAP BPC 7.5/7.0 NW, users are saying they are not getting data or there are some issues while getting data from R/3 system or ECC 6.0. Then what things do I need to consider to check, such as what DataSources or Cubes I need to check? So, how to solve this issue?
What things I need to consider for SAP NW BI 7.0 u2013 SAP BPC 7.5 NW (SP06, 07, 08) Implementation?
Your help is greatly appreciated.
Regards,
Qadeer

Hi,
New SP was released in February, and now most of the new bugs should been caught ,This has a Central Note. For SP06 it's Note 1527325 - Planning and Consolidation 7.5 SP06 NetWeaver Central Note to fix any issues. Most of the improvements in SP06 were related to performance, especially when logging on from the BPC clients.There you should be able to find a big list of fixes/improvements and Notes that describe those. Some of the Notes even have test description how to reproduce that issue in the old version.
hope this will help you

Performance Issue with BSIS(open accounting items)

Hey All,
 I am having serious performance issue with a accrual report which gets all open GL items, and need some tips for optimization.
The main issue is that I am accesing large tables like BSIS, BSEG, BSAS etc without proper indexes and that I am dealing with huge amounts of data.
The select itself take a long time and after that as I have so much data overall execution is slow too.
The select which concerns me the most is:
SELECT zuonr hkont gjahr belnr buzei budat blart wrbtr shkzg xblnr waers bukrs
 INTO TABLE i_bsis
 FROM bsis
 WHERE bukrs = '1000'
 AND hkont in r_hkont
 AND budat <= p_lcdate
 AND augdt = 0
 AND augbl = space
 AND gsber = c_ZRL1
 AND gjahr BETWEEN l_gjahr2 AND l_gjahr
 AND ( blart = c_re "Invoice
 OR blart = c_we "Goods receipt
 OR blart = c_zc "Invoice Cancels
 OR blart = c_kp ). "Accounting offset
I have seen other related threads, but was not that helpful.
We already have a secondary index on bukrs hkont and budat, and i have checked in ST05 that it does use it. But inspite that it takes more than 15 hrs to complete(maybe because of huge data).
Any Input is highly appreciated.
Thanks

Thank you Thomas for your inputs:
You said that R_HKONT contains several ranges of account numbers. If these ranges cover a significant
portion of the overall existing account numbers, then there is no really quick access possible via the
BSIS primary key.
Unfortunately R_HKONT contains all account numbers.
As Rob said, your index on HKONT and BUDAT does not help much, since you are selecting "<=" on
BUDAT. No chance of narrowing down that range?
Will look into this.
What about GSBER? Does the value in c_ZRL1 provide a rather small subset of the overall values? Then
an index on BUKRS and GSBER might be helpful.
ZRL1 does provide a decent selection . But I dont know if one more index is a good idea on overall
system performance.
I assume that the four document types are not very selective, so it probably does not pay off to
investigate selecting on BKPF (there is an index involving BLART) and joining BSIS for the additional
information. You still might want to look into it though.
I did try to investigate this option too. Based on other threads related to BSIS and Robs Suggestion in
those threads I tried this:
SELECT bukrs belnr gjahr blart budat
FROM bkpf INTO TABLE bkpf_l
 WHERE bukrs = c_pepsico
 AND bstat IN (' ', 'A', 'B', 'D', 'M', 'S', 'V', 'W', 'Z')
 AND blart IN ('RE', 'WE', 'ZC', 'KP')
 AND gjahr BETWEEN l_gjahr2 AND l_gjahr
 AND budat <= p_lcdate.
SELECT zuonr hkont gjahr belnr buzei budat blart wrbtr shkzg xblnr waers bukrs
 FROM bsis INTO TABLE i_bsis FOR ALL ENTRIES IN bkpf_l
 WHERE bukrs = bkpf_l-bukrs
 AND hkont IN r_hkont
 AND budat = bkpf_l-budat
 AND augdt = 0
 AND augbl = space
 AND gjahr = bkpf_l-gjahr
 AND belnr = bkpf_l-belnr
 AND blart = bkpf_l-blart
 AND gsber = c_zrl1.
The improves the select on BSIS a lot, but the first select on BKPF kills it. Not sure if this would help
improve performance.
Also I was wondering whether it helps on refreshing the tabe statistics through DB20. The last refresh
was done 7 months back. How frequently should we do this? Will it help?

Performance issue with Jdeveloper

Hi Guys,
I am experiencing strange performance issue with Jdeveloper 10.1.3.3.0.4157. There are many other threads regarding the performance issue in this forum, but the problem I have is a little bit different.
I have two computers: one is Athlon 3200+ with Vista and another one is P4 dual core 6400 with XP (service pack 2). Both of them have 2GB memory.
I am running the same simple project on both computer, but only the one with Vista has the problem. The problem is very similar to the problem mentioned in the thread:
Re: IDE has become extremely slow?
But it's much worse. It only happens only on JSF pages. Basically, any operations on the JSF pages are very slow. Loading the page, changing the attributes of a button in source editor, or even clicking the items in the design view take forever to run.
The first weird thing is that it may use 100% CPU, but it never recover, which means the 100% CPU usage never stops or when it stops, the Jdeveloper stops responding.
The second weird thing is that the project is not big. Actually, it's very small. The problem started to happen since last week. There are not big changes during the period. The only thing I can say is that we created two more JSF pages.
The third weird thing is that the same project never happened on the P4+XP box. When I open the project on the P4+XP box, it’s always fast and no CPU spike.
Any advises are welcome!
Thanks,
Steven

Hi Guys,
I re-made a simple test project for this problem and now I now always reproduce the problem in JDeveloper on both system (XP & Vista). Everytime I open this jspx file in the source editor and try to scroll up/down the source file, or manually delete an attribute, JDeveloepr will hang and the CPU usage is 0%.

Performance issue with MSEG table

Hi all,
I need to fetch materials(MATNR) based on the service order number (AUFNR) in the selection screen,but there is performance isssue with this , how to over come this issue .
Regards ,
Amit

Hi,
There could be various reasons for performance issue with MSEG.
1) database statistics of tables and indexes are not upto date.
because of this wrong index is choosen during the execution.
2) Improper indexes, because there is no indexes with the fields mentioned in the WHERE clause of the statement. Because of this reason, CBO would have choosen wrong index and did a range scan.
3) Optimizer bug in oracle.
4) Size of table is very huge, archive.
Better switch on ST05 trace before you run this statements, so it will give more detailed information, where exactly time being spent during the execution.
Hope this helps
