Oracle Per5formance Issue With Huge Data
Hi Everyone,
I needed one help from the techies here.
The issue I am facing is, I have got a set of oracle queries that I needed to execute often.
Previously the things were fine as the number of records were less.
But now I have gone into deep trouble as the new dump I have got is having tremendous amount of data.
For example one of the table my query used has got 8000000 records.
Can anyone tell me about the ways that I can use to improve the perforance level.
Most of the tables i have already seen are using indexes.
Thanks in Advance

SQL> set timing on

COUNT(*)
2332931003
Elapsed: 00:00:09.94Approx 1,125,793 I/O calls (majority logical and not physical) were needed and performed in 10 seconds.
Compare this to the following:
SQL> select count(*) from all_objects;
COUNT(*)
72873
Elapsed: 00:00:10.29A tiny percentage of rows in comparison with the 1st query above. 1,473,899 I/O calls make (majority also logical).
What are the common factors here? Elapsed execution time and the amount of I/O done. The execution time has nothing to do with the number of rows processed.
So if number of rows are effecting your database's performance, then your database design and physical implementation is not optimal - as it does not provide optimal I/O paths to the desired result sets that need to be determined by the database. In other words, the design is not scalable. Relational design is inherently scalable - when done correctly.
So I would think you need to review your design - both logical and physical.

I am having a issue with getting data useage alerts for my iphone 4s
I am having a issue with getting data useage alerts for my iphone 4s from AT&T. I do not download anything huge at all.
I looked into it and figured out that the phone dials out nightly at 12:29am every night. I went into my settings and went to general..about..diagnostics and useage..then diagnostics and useage data to see this. I then clicked don't send...but I am still getting useage alerts. Can anyone help me please...
ThanksHonestly, from reading the thread linked, they all come off as a bunch of whiney people that cannot be bothered to help themselves.
Little to nothing in that thread indicates an issue beyond inept consumers. Yes, I read several pages on the incessant gripes. Very few made any actual attempts to troubleshoot issues before whining about the "Apple issue" and those that did actual troubleshooting got their issues resolved.
So no, Apple has nothing to fix beyond a few specific devices that are experiencing hardware issues.
If you have actually put forth effort and done the basic troubleshooting, take the device to Apple for evaluation and possible replacement. Whining will get nothing accomplished. -
Has anyone had issues with Administration\Data Import/Export\Data Import???
Has anyone had issues with Administration\Data Import/Export\Data Import???
I have a client who has recently upgraded from V2007 to V8.81. They were succesfuly using this standard function to import supplier prices to their master price list, but now it has failed?
I have looked at the file they are importing and it appears to be fine.
On closer inspection, it did contain approx 46,000 entries, so I took the first 1,000 and created a test file, which imported fine.
The only issue I found was Speed, with the test file of 1,000 records taking about 30 Mins to import. This appeared to get slower and slower the further through the file it got!
Based on this, I have estimated that the whole file would takle about 13 hours to import. The client say that when they used to run it on version 2007 it was far quicker?
In practice, it does appear to run, but the speed is the issue. Having said this, I set the whole file to run last night (over night)and this morning it had appeared to hang after about 2,307 rows, with nothing else being updated.
Has anyone any ideas or is aware of performance issues like this?
Thanks,
IanAlways an option, but would you give your clients access to this tool?
Not sure really.
I have uploaded a copy of their database onto my test system and run the same routine. Its equally as SLOW
I can't gauage if its an issue with 8.81 that 2007 didn't have, as I only have the client's word on it, however I have no reason to disbelieve them.
Kind regards,
Ian -
Issue with 2LIS_02_SCL Data source
Hi Everybody,
I am facing the below 2 issues with 2lis_02_scl data source,
1) This is fetching only the records ETENR (Delivery Schedule Line Counter) value with ' 1 ', It is ignoring others ex:2,3 and 4. Hence Data is not reconciling with ECC system.
2) The standard field GLMNG is not getting any data, Data was existed in table(EKET) level. So i have written the code and data is coming now. But the problem is, This is not considering the ROCANCEL indicator it seems. All the other key figures values are coming in with Negative sign When ROCANCEL Value is ' X ' or ' R ', But this field is getting all the positive values irrespective of ROCANCEL indicator. Hence showing the incorrect values compared to the ECC.
Can anybody help me on this,
Regards,

CVC creation - Strange issue with Master data table of 9AMATNR
Hi Experts,
We have encountered a strange issue with Master data table (/BI0/9APMATNR) of info object 9AMATNR.
We have a BADI implemented for checking the valid Characteristic before creation of the CVC using transaction /SAPAPO/MC62. This BADI puts a select on master data tab of material /BI0/9APMATNR and returns no value. But the material actually exists in the table (checked through SE16).
Now we go inside the info object 9AMATNR and go to the Master data Tab. There we go inside the master table
/BI0/9APMATNR and activate that. After activating the table it is read by the select statement inside BADI (Strange) and allows the CVC to be created.
Ideally it should not allow us to activate the SAP standard table /BI0/9APMATNR. I observed that in technical settings of this table it has single record buffering as switched on. (But as per my knowledge buffer gets refreshed every 2 to 4 mins and not in 2 days or something).
Your expert comment is valuable to us. Thanks.
Best Regards,
Chandan DubeyHi Chandan,
Try to use a WAIT statment with 5 seconds before your select statment.
I'm not sure whether this will work. Anyway check it and let me know the result.

SQL Query : Order By issue with HUGE Table
Hello friends,
I have been through a terrible issue with order by. I would appreciate your help. Please let me know, your input for my case:
=> if i run select query it returns result quick in some milliseconds. (sql dev. fetches 50 rows at a time)
=> if i run select query with where condition and column (say A) in where condition is even indexed and i have order by and that order by column (say B) is also indexed.
Now, here is the issue:
1. if no. of rows with that where condition can filter yielding small result set then order by works fine .. 1-5 sec which is good.
2.*if no. of rows with that where condition can filter yielding Large result set, say more than 50,000 then with order by then the wait time is exponential.... i have even waited 10+ mins to get the result back for 120,000 records.*
Is order by takes that long for 100K records ... i think something else if wrong... your pointer will really be helpful... i am very new to sql and even newer for large table case.
I am using SQL Developer Version 2.1.1.64
and Oracle Database 11g Enterprise Edition Release 11.1.0.7.0 - 64bit Production
Thank you so much.
Edited by: 896719 on Jan 11, 2013 8:38 AMYes you are correct, but my concentration was on order by thing, so it will do full scan of table so i was putting that ... and was also wondering if millions of record in table should not be a issue...???
Any way for the explain plan , when just a value in the where changes there is the huge difference i want to point out too as below:

How Oracle to deal with the data lose?-----QNo.104
In incomplete recovery,some data will be lost. How Oracle to deal with it?
For example, at 9:00am, you find that it is a mistake to drop a user(you dropped it at 8:30am). But other users' transactions are in progress. A lot of data is input between 8:30 and 9:00. If decide to make a incomplete recovery, does this means all the data input between 8:30 and 9:00 will be lost?

I dont think that you would loose any data.
The other workaround for this issue would be,
I would clone this on other server just before the user dropped, take the export and then import the user in the production.
Is this satisfy your question?

10g Reports issue with XML Data Source
Hi,
Has anybody ever encountered an issue with Oracle 10g report using an XML as the data source? What happens is, some of the values in the XML are printed to the wrong column.
One of the elements in our XML file is a complex type with 10 elements under it. The first 5 are picked up properly, but the last 6 are not. Elements #6 to #9 has a minimum occurence of 0. What happens is when element #6 is present, but #7 is, the value for element #7 is passed on to element #6.
The XSD and XSL files are both valid since the reports were working when we were still using 9i. There is no hidden logic in the report which might cause this issue to come up, i.e., the report just picks up the values from the XML and prints it to the appropriate columns.
Any help will be greatly appreciated.XSD used

Data Pump issue with nls date format
Hi Friends,
I have a database with nls date format 'DD/MM/YYYY HH24:MI:SS' from where I wish to take export from. I have a target database with nls date format 'YYYY/MM/DD HH24:MI:SS' . I have a few tables whose create statements have some date fields with DEFAULT '01-Jan-1950' and these CREATE TABLE statements when processed by Data pump is getting failed in my target database. These tables are not getting created due to this error
Failing sql is:
CREATE TABLE "MCS_OWNER"."SECTOR_BLOCK_PEAK" ("AIRPORT_DEPART" VARCHAR2(4) NOT NULL ENABLE, "AIRPORT_ARRIVE" VARCHAR2(4) NOT NULL ENABLE, "CARRIER_CODE" VARCHAR2(3) NOT NULL ENABLE, "AC_TYPE_IATA" VARCHAR2(3) NOT NULL ENABLE, "PEAK_START" VARCHAR2(25) NOT NULL ENABLE, "PEAK_END" VARCHAR2(25), "BLOCK_TIME" VARCHAR2(25), "FLIGHT_TIME" VARCHAR2(25), "SEASON" VARC
ORA-39083: Object type TABLE failed to create with error:
ORA-01858: a non-numeric character was found where a numeric was expected
The table create sql which adds a column as ' VALID_FROM DATE DEFAULT '01-jan-1970' ' which I think is the issue. Appreciate if someone can suggest a way to get around with this. I have tried altering the nls of source db to be same as target database. Still the impdp fails.
Database is 10.2.0.1.0 on Linux X86 64 bit.
Thanks,
SSN
Edited by: SSNair on Oct 27, 2010 8:25 AMAppreciate if someone can suggest a way to get around with this.change the DDL that CREATE TABLE to include TO_DATE() function.
With Oracle characters between single quote marks are STRINGS!
'This is a string, 2009-12-31, not a date'
When a DATE datatype is desired, then use TO_DATE() function. -
ORACLE olap - dimension with huge number of members.
Hi Experts,
I have modeling a ORACLE OLAP cube with 10 dimensions. I have one of the dimensions which have huge leaf members...(probably 1 billion).. How many dimension members i can have for one dimension. Is there any limitation to the dimension members ?
Thanks and Regards
SivaHi there,
I'm not sure of the theoretical limits, but I would never recommend trying to build a dimension with 1 billion members.
In situations were such granular data exists, it is common to leave this in table and load data into the OLAP cube at a more aggregate level.
Which business entity are you trying to model in a 1 billion member dimension?
Thanks,
Stuart Bunby

In the above wsdl the collection of fintObjInst if of type xs:anytype. From the wsdl, I do not see the xsd mapping for AccountIC which includes Name and Desc. Due to which, when invoking the web service from a different client like c#(by creating proxy business service), I am unable to set the parameters for AccountIC. I am using JAX-WS stack and WLS 10.3. I have already looked at blog http://weblogs.java.net/blog/kohlert/archive/2006/10/jaxws_and_type.html but unable to solve this issue. However, at run time using a tool like SoapUI, when this wsdl is imported, I am able to see all the params related to AccountIC class.
Can some one help me with this.
Thanks,
Sudha.Did you try adding the the XmlSeeAlso annotation to the webservice
@XmlSeeAlso({<package.name>.AccountIC.class})
This will add the schema for the data type (AccountIC) to the WSDL.
Hope this helps.

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 issue with extreme data distribution using histogram
Hi
We have a performance stability issue which we later found out is cause by the bind variable and histogram for a particular column when it was use as part of equality predicate. Assume the column name is parent_id0.
There is also an index on parent_id0.
Our temporary workaround is to install the good plan when it is started.
This is on database 10.2.0.3. I have a table with 2570149 rows, there is one common value(value 0) that represent about 99.91% of the total rows.
When i do
select parent_id0, count(*)
from table1
group by parent_id0
order by parent_id0;
I'm getting 187 rows and i would assume to have 187 buckets to have a better representation. The first row have the count nearly to 99.91%. The rest rows are having count something like 1 or 2 or less than 200.
With the auto gather, Oracle came up with 5 bucket. When i check the sample size, i only see oracle uses 2.215% of all the total rows at that time.
Column name Endpoint num Endpoint value
PARENT_ID0 5,579 0

Is the problem due to the wrong sample size and hence the histogram is miscalculated.
When i trace the sql with 10053, i see something like this..seems like some value is not capture in the histogram.
Using prorated density: 3.9124e-07 of col #2 as selectivity of out-of-range value pred
What i need to do to have a correct and stable execution plan?
Thank youHi, its an OLTP environment.
The problem is this sql has 4 tables to join, table1 (2.5 mil rows), table2 (4 mil), table3 (4.6 mil) and table4 (20 mil)
By right, the table with the highest filter ratio is table1. However, from the plan, oracle is using table3 as the driving table. The moment i take away the parent_id0 as part of the predicate, Oracle choose the right driving table (table1).
Here is the sql structure
select ...
from table1, table2, table3, table4
where table1.id = :1 and table1.parent_id0 :=2
and ...
We have index on id column too.
From the application, the application will never pass in value 0 for the parent_id0. Therefore, we will be querying 0.09 percent all the time from that particular query.
p/s: i'm sorry that i'm not able to paste the exact sql text here -
Data load issue with export data source - BW 3.5
Hi,
We are facing issues in loading data with the help of export data source.
We have created export data source of 0PCA_C01 cube. With the help of this export datasource, we are loading data to other custom cube. Scenario is working fine in development server.
But when we transported objects to quality server data is not getting loaded to custom target cube.
It is extracting zero records. All transports are ok and we have generated export datasource in quality before transports .Also regenerated export datasource after transport and activated infosource, update rule via RS* programs. Every object is active but data is not getting extracted.
RSA3 for 80PCA_C01 datasource isn't extracting any record in Quality. Records getting extracted in development. We are in BW 3.5 with patch level 19.
Please guide us to resolve the issue.
Thanks,
AdityaHi
Make sure that you have relevant Role & Authorization at Quality/PRS.
You have to Transport the Source Cube first and then Create a Generate Export Data Source in QAS. Then, replicate data sources for BW QAS Soruce System. Make sure this replicated Data Source in QAS. Only then can transport new update rules for second cube.
Hope it helps and clear -
Issue with the data of attachment of the mail with FM 'SO_NEW_DOCUMENT_ATT'
Hi Gurus,
I am developing my program in SAP R/3 4.7 system.
I have a requirement to attach a txt file to the email. I am able to attach the file and fill the contents of the file.
But the issue is with the data in the file. There are no line breaks in the data of file and all the words are saperated by space.
For EG: If I have filled 2 records(line1,line2) in the internal table provided to content_bin field, the data in the attachment looks like this.
l i n e 1 l i n e 2
but I want the data to be like below:
line1
line2
Below is my code:
Fill the document data and get size of attachment
DATA:w_cnt TYPE i.
DATA: WA_ATTACH LIKE LINE OF P_ATTACHMENT.
DESCRIBE TABLE p_attachment LINES w_cnt.
READ TABLE p_attachment INTO WA_ATTACH INDEX w_cnt.
Fill the document data and get size of attachment

it_packing_list-obj_name = 'Job log'.
it_packing_list-doc_size = it_packing_list-body_num * 255.
APPEND it_packing_list.
Add the recipients email address

Kindly let me know to procedure to solve the iisue
Thanks in advance,
Kiran Kumar KHi Kira,
you can try to use a CR_LF to separate the records.
constants: con_cret type c value cl_abap_char_utilities=>CR_LF.
And when you append your record to the internal table add to the end the con_cret.
LOOP AT t_build into wa_charekpo.
CONCATENATE wa_charekpo-order wa_charekpo-kunnr
wa_charekpo-sel
INTO it_attach SEPARATED BY con_tab.
CONCATENATE con_cret it_attach INTO it_attach.
APPEND it_attach.
ENDLOOP.
