Performance Problem with several Database accesses
Hello
We have SAP ERP 2004 running on a Oracle DB 9.x and we face a strange behavior of our system. Sometimes it is very slow. MB51 with 1 Material and 1 Month as selection runs into timeout. But i faced the most significant (or strange) problem using SE16 with table bseg. If i use Company code, one item number and year as a selection, it is very fast. If i put in 2 items numbers instead of one, it takes 15 minutes to show the result. This happens everytime i try it.
For me it looks like the system is doing a sequential read instead of using the proper index. This "wrong index" behavior could be the source of many of our performance problems.
Does anybody have a suggestion for me, how to fix this problem?
Thanks in advance
Hans-Peter

As mentioned above you can active trace with ST05 to monitor the problematic SQL request. With the explain function, you will see the estimated cost of the request and the used index.
An other way is during the execution of the request --> ST04 -> performance -> Wait event analysis -> Session monitor
If you use the IN option, your request could be very expensive. And in many cases, the reads can only performed with sequential access.
For an overlook of possible indexes for a table, you can use the DB05. To interpret the results : an index is representative when you have numerous distinct values for a few 'rows per generic keys'
Hope this will help you

we have problems with our reports in Collection Manager again. We reboot the CM, but the problems continue.
This is the log of the CM. What can be the problem? Thanks tomo

Performance problem with sdn_nn - new 10g install
I am having a performance problem with sdn_nn after migrating to a new machine. The old Oracle version was 9.0.1.4. The new is 10g. The new machine is faster in general. Most (non-spatial) batch processes run in half the time. However, the below statement is radically slower. The below statement ran in 45 minutes before. On the new machine it hasn't finished after 10 hours. I am able to get a 5% sample of the customers to finish in 45 minutes.
Does anyone have any ideas on how to approach this problem? Any chance something isn't installed correctly on the new machine (the nth version of the query finishe, albeit 20 times slower)?
Appreciate any help. Thanks.

a.geometry,

1
) = 'TRUE'
;Dan,
customers 110,000 (involved in this query)
stores 28,000
Here is the execution plan on the current machine:
CREATE TABLE STATEMENT cost = 81947
LOAD AS SELECT
PX COORDINATOR
PX SEND QC (RANDOM) :TQ10000
ROW NESTED LOOPS
1 1 PX BLOCK ITERATOR
1 1ROW TABLE ACCESS FULL CUSTOMERS
1 3 PARTITION RANGE ALL
1 3 TABLE ACCESS BY LOCAL INDEX ROWID STORES
DOMAIN INDEX STORES_SIDX
I can't capture the execution plan on the old database. It is gone. I don't remember it being any different from the above (full scan customers, probe stores index once for each row in customers).
I am trying the query without the create table (just doing a count). I'll let you know on that one.
I am at 10.0.1.3.
Here is how I created the index:
create index stores_sidx
on stores(geometry)
indextype is mdsys.spatial_index LOCAL
Note that the stores table is partitioned by range on store type. There are three store types (each in its own partition). The query returns the nearest store of each type (three rows per customer). This is by design (based on the documented behavior of sdo_nn).
In addition to running the query without the CTAS, I am also going try running it on a different machine tonight. I let you know how that turns out.
The reason I ask about the install, is that the Database Quick Installation Guide for Solaris says this:
"If you intend to use Oracle JVM or Oracle interMedia, you must install the Oracle Database 10g Products installation type from the Companion CD. This installation optimizes the performance of those products on your system."
And, the Database Installlation Guide says:
"If you plan to use Oracle JVM or Oracle interMedia, Oracle strongly recommends that you install the natively compiled Java libraries (NCOMPs) used by those products from the Oracle Database 10g Companion CD. These libraries are required to improve the performance of the products on your platform."
Based on that, I am suspicious that maybe I have the product installed on the new machine, but not correctly (forgot to set fast=true).
Let me know if you think of anything else you'd like to see. Thanks.

Performance problems with EP 6 and MS IE
Hi everybody,
since a couple of days, we are facing a sever performance problem with our SAP EP 6.0. When I access the system with MS Internet Explorer 6.0, it takes 5-10 minutes after the Login. With Firefox Browser, the performance is ok. Therefore I assume that it must be a problem with the IE settings. Does anybody know a solution?
Best regards,
MichaelThere are a few things that this could be. I've seen the setting "Empty Temporary Internet Files folder when browser is closed" cause a lot of performance problems (This is in the advanced settings in your IE).
This will cause your cache to be cleared out each time the browser is closed and cause a lot more data to be downloaded each time you login to the system.
For more analysis I'd recommend putting a tool like HTTPWatch into your IE browser and seeing which requests are using the most time. -
Performance problem with Orcacle / Crystal reports 8.5 / ASP
Hi,
I have a performance problem with reports running crystal reports 8.5 with oracle databases.
Fetching data appears to be slow. Oracle trace reports (tkprof) shows that fetchsize=1.
Fetchsize in Oracle ODBC is 15 (default).
How can I update te fetchsize in crystal reports?
I would appreciate any help.CR XI R2 is also still available for purchase. This is the last version of CR to use the RDC. Contact sales at 866-681-3435.

Performance problem with ojdbc14.jar
Hi,
We are having performance problem with ojdbc14.jar in selecting and updating (batch updates) entries in a table. The queries are taking minutes to execute. The same java code works fine with classes12.zip ans queries taking sub seconds to execute.
We have Oracle 9.2.0.5 Database Server and I have downloaded the ojdbc14.jar from Oracle site for the same. Tried executing the java code from windows 2000, Sun Solaris and Opteron machines and having the same problem.
Does any one know a solution to this problem? I also tried ojdbc14.jar meant for Oracle 10g, that did not help.
Please help.
Thanks
YuvaMy code is doing some thing which might be working well with classes12.zip and which does not work well with ojdbc14.jar? Any general suggestions to make the code better, especially for batch updates.
But for selecting a row from the table, I am using index columns in the where cluase. In the code using PreparedStatement, setting all the reuired fields. Here is the code. We have a huge index with 14 fields!!. All the parameters are for where clause.
if(longCallPStmt == null) {
longCallPStmt = conn.prepareStatement(longCallQuery);
log(Level.FINE, "CdrAggLoader: Loading tcdragg entry for "
+GeneralUtility.formatDate(cdrAgg.time_hour, "MM/dd/yy HH"));
longCallPStmt.clearParameters();
longCallPStmt.setInt(1, cdrAgg.iintrunkgroupid);
longCallPStmt.setInt(2, cdrAgg.iouttrunkgroupid);
longCallPStmt.setInt(3, cdrAgg.iintrunkgroupnumber);
longCallPStmt.setInt(4, cdrAgg.iouttrunkgroupnumber);
longCallPStmt.setInt(5, cdrAgg.istateregionid);
longCallPStmt.setTimestamp(6, cdrAgg.time_hour);
longCallPStmt.setInt(7, cdrAgg.icalltreatmentcode);
longCallPStmt.setInt(8, cdrAgg.icompletioncode);
longCallPStmt.setInt(9, cdrAgg.bcallcompleted);
longCallPStmt.setInt(10, cdrAgg.itodid);
longCallPStmt.setInt(11, cdrAgg.iasktodid);
longCallPStmt.setInt(12, cdrAgg.ibidtodid);
longCallPStmt.setInt(13, cdrAgg.iaskzoneid);
longCallPStmt.setInt(14, cdrAgg.ibidzoneid);
rs = longCallPStmt.executeQuery();
if(rs.next()) {
cdr_agg = new CdrAgg(
rs.getInt(1),
rs.getInt(2),
rs.getInt(3),
rs.getInt(4),
rs.getInt(5),
rs.getTimestamp(6),
rs.getInt(7),
rs.getInt(8),
rs.getInt(9),
rs.getInt(10),
rs.getInt(11),
rs.getInt(12),
rs.getInt(13),
rs.getInt(14),
rs.getInt(15),
rs.getInt(16)
}//if
end_time = System.currentTimeMillis();
log(Level.INFO, "CdrAggLoader: Loaded "+((cdr_agg==null)?0:1) + " "
+ GeneralUtility.formatDate(cdrAgg.time_hour, "MM/dd/yy HH")
+" tcdragg entry in "+(end_time - start_time)+" msecs");
} finally {
GeneralUtility.closeResultSet(rs);
GeneralUtility.closeStatement(pstmt);
Why that code works well for classes12.zip (comes back in around 10 msec) and not for ojdbc14.jar (comes back in 6-7 minutes)?
Please advise. -

Hi,
This is what I know and please if any expert think its incorrect, please do correct me.
BSEG is a cluster table with BUKRS, BELNR, GJAHR and BUZEI as the key whereas other key will be stored in database as raw data thus SAP apps will need to convert that raw data first if we are using other keys in where condition. Hence, I suggest to use up to buzei in the where condition and filter other condition in internal table level like using Delete statement. Hope its help.

A problem with a session Access
Hi Olivier,
To connect with Forte while running distributed you must use System DNS
instead of User DNS on the server. The ftexec.exe on your server partition
will be launched by the NodeMgr running as UID SYSTEM. User DNS are not
available to processes running as UID SYSTEM.

Performance problem with CR SDK
Hi,
I'am currently on a customer site and I have the following problem :
The client have a performance problem with a J2EE application wich call a Crystal report with th CR SDK. To reproduce the problem on the local machine (the CR server), I have developped a little jsp page wich used the Crystal SDK to open a Crystal report on the server (this report is based on a XML data source), setting the new data source (with a new xml data flow) and refresh the report in PDF format.
The problem is that the 2 first sequences take about 5 seconde each (5 sec for the opening report and 5 seconds for the setting data source). Then the total process take about 15 seconds to open and refresh the document that is very long for a little document.
The document is a 600Ko file, the xml source is a 80Ko file.
My jsp page is directly deployed on the tomcat of the Crystal Report Server (CRXIR2 without Service Pack).
The Filestore and the MySQL database are on the CR server.
The server is a 4 quadripro (16 proc) with 16Go of RAM and is totally dedicated to Crystal Report. For the moment, there is no activity on the server (it is also used for the test).
The mains jsp orders are the followings :
IEnterpriseSession es = CrystalEnterprise.getSessionMgr().logon("administrator", "", "EDITBI:6400", "secEnterprise");
IInfoStore infoStore = (IInfoStore) es.getService("", "InfoStore");
IInfoObjects infoObjects = infoStore.query("SELECT * FROM CI_INFOOBJECTS WHERE SI_NAME='CPA_EV' AND SI_INSTANCE=0 ");
IInfoObject report = (IInfoObject) infoObjects.get(0);
IReportAppFactory reportAppFactory = (IReportAppFactory)es.getService("RASReportFactory");
ReportClientDocument reportClientDoc = reportAppFactory.openDocument(report.getID(), 0, null);
IXMLDataSet xmlDataSet = new XMLDataSet();
xmlDataSet.setXMLData(new ByteArray(ligne_data_xml));
xmlDataSet.setXMLSchema(new ByteArray(ligne_schema_xml));
DatabaseController db = reportClientDoc.getDatabaseController();
db.setDataSource(xmlDataSet, "", "");
ByteArrayInputStream bt = (ByteArrayInputStream)reportClientDoc.getPrintOutputController().export(ReportExportFormat.PDF);
My question is : does this method is the good one to do this ?
Thank's in advance for your help
Best regards

Hi all,
I am facing some problem with ORACLE database while configuring one JDBC scenario in the receiver side. I have configured one JDBC scenario like FILE TO JDBC. As JDBC is at receiver side i have provided the input file with the following format ,
<root>
<StatementName1>
<dbTableName action="INSERT">
<table>employee</table>
<access>
<flag>NO</flag>
<ID>567</ID>
<NAME>134</NAME>
</access>
</dbTableName>
</StatementName1>
</root>
But in the ORACLE database all my columns are in the uppercase.
So when i have tried to send this input file to process through JDBC receiver side then i have faced the below error :
FATAL ERROR: Column 'flag' does not exist in table 'employee'
Then I have tried to check with sender side processing of JDBC adapter. By using the SQL statements as
SELECT * FROM EMPLOYEE WHERE flag='NO'
UPDATE EMPLOYEE SET Flag='YES' WHERE flag='NO'
Here it worked fine.
Now my question is,
If the same adapter is working when we are writing a query directly(sender side), then we must also allow case independence in the auto generated SQL part(receiver side).
The JDBC drivers for both SQL server and Oracle, supports the same java code, for accessing the DB, irrespective of the case of the column names.
Please clarify this doubt as soon as possible.
Thanks,
Soorya.Hi Dharmaveer,
When I go with the following input file,
<root>
<StatementName1>
<dbTableName action="INSERT">
<table>EMPLOYEE</table>
<access>
<FLAG>NO</FLAG>
<ID>666</ID>
<NAME>SSS</NAME>
</access>
</dbTableName>
</StatementName1>
</root>
I will get the following query with succesfull processing.
INSERT INTO EMPLOYEE (FLAG, ID, NAME) VALUES (NO, 666, SSS)
when i go with this input file,
<root>
<StatementName1>
<dbTableName action="INSERT">
<table>EMPLOYEE</table>
<access>
<flag>NO</flag>
<ID>777</ID>
<NAME>TTTT</NAME>
</access>
</dbTableName>
</StatementName1>
</root>
Then i am facing this problem,
Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'EMPLOYEE' (structure 'StatementName1'): java.sql.SQLException: FATAL ERROR: Column 'flag' does not exist in table 'EMPLOYEE'
Here I cant get any SQL statement as it is not successfull.
I have gone through your link but it also says to modify the column in the input file which is not possible for me. Can you please help me in this regard?
Thanks,

I have a tesco router and an external hard drive attached to it as a network drive (shared) for my macbook and MB-Air. Have no problems with my MB accessing it, but with MB-AIR it says - 'the version of the server you are trying to connect to is not supported. pls contact your system administrator to resolve the problem'. MB-Air uses maverick downloaded yesterday - upgrade from mountain lion. MB uses snow leopard still, as i am quite used to it and am thinking of upgrade if mavericks work fine on air. Also have parallel on snow leopard but it is no longer supported according to mac website - if i upgrade am i going to lose my parallel and will have to buy a new one!!!
Yes, the Old Master file has a folder for each year where I find all photos from that specific year. I am attaching a screen shot of the file.
In the meantime i have managed to download all photos (it did not download any video files though in mpg, avi, 3gp, m4v,mp4 and mov format) to a new iphoto library. Unfortunately the photos are quite mixed and often doubled up. I ma considering to purchase iphoto library which checks all duplicates in iphoto. this will save me a lot of time. What do you think? -
Performance problems with jdk 1.5 on Linux plattform
Performance problems with jdk 1.5 on Linux plattform
(not tested on Windows, might be the same)
After refactoring using the new features from java 1.5 I lost
performance significantly:
public Vector<unit> units;
The new code:

I expected the opposite.

Performance problems with new Java Tiger style recommendations
Performance problems with jdk 1.5 on Linux plattform
(not tested on Windows, might be the same)
using the new style recommendations.
I need fast Vector loops for high speed mathematical calculations, some
hints about the fastest way to program that loop would be also great!
After refactoring using the new features from java 1.5 (as recommended from
SUN) I lost performance significantly:
using a vector:
public Vector<unit> units;
The new code (recommended from SUN for Java Tiger for redesign):
for (unit u: units) u.accumulate();
runs more than 30% slower than the old code:
for (int i = 0; i < units.size(); i++) units.elementAt(i).accumulate();
I expected the opposite.
Is there any information available that helps?
The following additional information I got from Mr. Shankar Unni:
I got some fairly anomalous results comparing ArrayList and Vector: for the
1.5-style loops, ArrayList was faster then Vector, but for a loop with get()
calls, Vector was faster. Vector was even faster than that using
elementAt(), which was a surprise:
For a million summing iterations over a 100-element array:
vector elementAt loop took 3446 ms.
vector get loop took 3796 ms.
vector iterator loop took 5469 ms.
arraylist get loop took 4136 ms.
arraylist iterator loop took 4668 ms.If your topic doesn't change, please stay in your original post.

Performance problems with SAP GUI 7.10 and BEx 3.5 Patch 400?
Hi everybody,
we installed SAP GUI 7.10 and BEx 3.5 Patch 400 and detected hugh performance problems with this version in comparison to the SAP GUI 6.40 and BEx 3.5 or BEx 7.0 Patch 800.
Does anybody detect the same problems?

Performance Problems with "For all Entries" and a big internal table
We have big Performance Problems with following Statement:
SELECT * FROM zeedmt_zmon INTO TABLE gt_zmon_help
FOR ALL ENTRIES IN gt_zmon_help
WHERE
status = 'IAI200' AND
logdat IN gs_dat AND
ztrack = gt_zmon_help-ztrack.
In the internal table gt_zmon_help are over 1000000 entries.
Anyone an Idea how to improve the Performance?

You can't expect miracles. With over a million entries in your itab any select is going to take a bit of time. Do you really need all these records in the itab? How many records is the select bringing back? I'm assuming that you have got and are using indexes on your ZEEDMT_ZMON table.
In this situation, I'd first of all try to think of another way of running the query and restricting the amount of data, but if this were not possible I'd just run it in the background and accept that it is going to take a long time.
