Reliability of data retrieval

One of our clients which is a bank raised this question from me. So I seek the help from you guys.
The question was how reliable a generated report is. In other words when a report is generated by pulling data, does BI server grabs all
the related data. Sometimes a report may be generated with with most of the related data but not all. There may be several reasons for this like
timeout, interruption to the database connection or any other. So in a situation like this how OBI handles this? Either the report should be complete or no report at all (atomic). Also if a report is generated only with a subset of all related data, does OBI indicate whether it generated the report but encountered errors.

Often in these cases the BI-server and or Presntation server cache are to blame.If Obiee doesn't regonise the request as "new" then it will try to resolve it against the cache first. Also very large reports can cause a time out against the webserver leaving the report only partly rendered.

Query Error Information: Result set is too large; data retrieval ......

Hi Experts,
I got one problem with my query information. when Im executing my report and drill my info in my navigation panel, Instead of a table with values the message "Result set is too large; data retrieval restricted by configuration" appears. I already applied "Note 1127156 - Safety belt: Result set is too large". I imported Support Package 13 for SAP NetWeaver 7. 0 BI Java (BIIBC13_0.SCA / BIBASES13_0.SCA / BIWEBAPP13_0.SCA) and executed the program SAP_RSADMIN_MAINTAIN (in transaction SE38), with the object and the value like Note 1127156 says... but the problem still appears....
what Should I be missing ?????? How can I fix this issue ????
Thank you very much for helping me out..... (Any help would be rewarded)

You may ask your basis guy to increase ESM buffer (rsdb/esm/buffersize_kb). Did you check the systems memory?
Did you try to check the error dump using ST22 - Runtime error analysis?

WAD : Result set is too large; data retrieval restricted by configuration

Hi All,
When trying to execute the web template by giving less restiction we are getting the below error :
Result set is too large; data retrieval restricted by configuration
Result set too large (758992 cells); data retrieval restricted by configuration (maximum = 500000 cells)
But when we try to increase the number of restictions it is giving output. For example if we give fiscal period, company code ann Brand we are able to get output. But if we give fical period alone it it throwing the above error.
Note : We are in SP18.
Whether do we need to change some setting in configuration? If we yes where do we need to change or what else we need to do to remove this error
Regards
Karthik

Hi Karthik,
the standard setting for web templates is to display a maximum amount of 50.000 cells. The less you restrict your query the more data will be displayed in the report. If you want to display more than 50.000 cells the template will not be executed correctly.
In general it is advisable to restrict the query as much as possible. The more data you display the worse your performance will be. If you have to display more data and you execute the query from query designer or if you use the standard template you can individually set the maximum amount of cells. This is described over [here|Re: Bex Web 7.0 cells overflow].
However I do not know if (and how) you can set the maximum amount of cells differently as a default setting for your template. This should be possible somehow I think, if you find a solution for this please let us know.
Brgds,
Marcel

Result set is too large; data retrieval restricted by configuration

Hi,
While executing query for a given period, 'Result set is too large; data retrieval restricted by configuration' message is getting displayed. I had searched in SDN and I had referred the following link:
http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/d047e1a1-ad5d-2c10-5cb1-f4ff99fc63c4&overridelayout=true
Steps followed:
1) Transaction Code SE38
2) In the program field, entered the report name SAP_RSADMIN_MAINTAIN and Executed.
3) For OBJECT, entered the following parameters: BICS_DA_RESULT_SET_LIMIT_MAX
4) For VALUE, entered the value for the size of the result set, and then executed the program:
After the said steps, the below message is displayed:
OLD SETTING:
OBJECT = VALUE =
UPDATE failed because there is no record
OBJECT = BICS_DA_RESULT_SET_LIMIT_MAX
Similar message is displayed for Object: BICS_DA_RESULT_SET_LIMIT_DEF.
Please let me know as to how to proceed on this.
Thanks in advance.

Thanks for the reply!
The objects are not available in the RSADMIN table.

Real tough data retrieval - assistance needed

Late 2011 Macbook Pro with 500GB hard drive
Lion 10.7
One morning out of absolutely nowhere I get this grey screen with a flashing question mark folder. I take it to the geniuses at the Apple store and they tell me my hard drive has failed (no explanation). My mac is under warranty so they gave me a new hard drive for free, bagged my old hard drive and told me "good luck" retrieving the data.
I'm on a mission to retrieve the data without paying for services. I have never retrieved data before but I've been doing a lot of forum reading and I have been getting protips from an IT friend who has saved my PC data before.
As of now, I have been unable to even access the hard drive and so I am reaching out to the community to help me conquer this project.
the problem is not the OS (according to Apple store)
when hooking up with the dongle, neither Finder nor Disk Utility detect the bad drive
the drive will spin when forced by the dongle (so I've ruled out the freezer method)
I was advised (by friends and forums alike) to download so powerful data retrieval software:
Data Rescue [did not detect bad external drive]
Disk Drill [did not detect bad external drive]
TestDisk (http://www.cgsecurity.org/wiki/TestDisk) [I can get it up and running but I have no idea how to use this software]
So that seems to be the big problem, when I hook up my failed drive as an external hard drive, there is no acknowledgement from my MBP that it is connected and as such data recovery programs cannot access it. When I still had it installed in my computer, there was no clicking sound and it doesn't seem like any of the components are jammed up as it still spins.
Where do I go from here? Please keep in mind that I am new to resolving my own technical problems but I'm willing to learn. Tired of being one of those people who look at computer parts and get anxious.
NOTE: I haven't tried Target Mode as I do not have a firewire cable or access to another mac (yet). If you think I should try this, please let me know.

A hard drive that will not divulge BOTH its Make&Model and a reasonable size/capacity to the likes of Disk Utility and data rescue programs has died, and connot be repaired with any software.
Target Disk mode will not improve anything. The drive is read as a Mac Volume by software. If it won't mount under Mac OS X, it won't mount under Target Disk Mode.

Should I use a data retrieval service or software to recover data ?

Please pardon the length of this post.
Here's the setup for our office:
Computer 1:

Computer 3:

1 GHZ PowerPC G4 IMac Flat Screen:
256 MB DDR SDRAM
I have 2 LaCie Big Disk d2 Extremes daisy chained and connected to the IMac. We use the first to store all of our data to keep our local disks free. The second d2 is the backup to the first. The other 2 computers connect to the d2's via an ethernet hub. The d2's are each partitioned into 4 compartments.
A couple of days ago I started the system up when I got in in the morning, and the main d2 would not open. I ran disk utility, but it said that the drive was damaged beyond it's ability to repair. I ran DiskWarrior, and it gave me this message:
"The directory of disk 'G4' cannot be rebuilt. The disk was not modified. The original directory is too severely damaged. It appears another disk utility has erased critical directory information. (3004, 2176)."
I contacted Disk Warrior tech support and after a series of exchanges that had me send him dated extracted from the terminal function, he said this:
"It appears that the concatenated RAID inside your LaCie
drive has failed (your 500GB drive is actually 2 250GB
hard drives). That is why we only saw 2 partitions
on "disk3". A possible cause could be a failed bridge
in the case.
You may be looking at sending this drive to a data recovery service.
However, it is possible that we may be able to recover data
from the partitions that we CAN see. What we would be doing would cause no damage to your data
unless the hard drives were having a mechanical failure (ie, the
head crashed and was contacting the platters, similar to scratching
a record). But from what I've seen, I don't feel that is the case.
I believe the piece of hardware that 'bridges' the two drives to
make them act as one has failed. that's why we can only see data
about 1 of the 2 drives in the case.
We would only be attempting to gather data off the drive. Since
data recovery services sometimes charge for amount of data retrieved,
it's up to you how you want to proceed."
Most of the data from the past 5 years for our business stands at being lost. Only some of it had been properly backed up on the second drive, due to some back up software issues. I want to do whatever I can to retrieve all of, or at least some of the data. From what the Alsoft technician said, do you think that the data recovery software available to the consumer is going to be robust enough to retrieve at least the data from the one disk in the drive that is recognizable (there are 2 250gig disks in the d2X. Only one is responding at all). If so, do these Softwares further damage the disks? Or should I just send the drive to a data recovery service?
I'd like to try to extract some of it myself via over the counter retrieval software, but I don't know whether to trust these programs?
Any advice would be greatly appreciated.
Thanks in advance.

My 2 cents:
I have used FileSalvage
http://www.subrosasoft.com/OSXSoftware/index.php?mainpage=product_info&productsid=1
to recover files from damaged disks. It works as advertised, within limits. Some files may be too damaged to recover. More importantly yo get to scan the disk before actually recovering, and it will give you a list of what it thinks it can recover.
My experience was that it recovered approx 85% of the data.
YMMV but they do have a trial.

Report Developed in Webi Rich Client Consuming more time in Data Retrieval

Dear All,
I am a BO Consultant, recently in my project I have developed one report in Webi Rich Client., at the time of development and subsequent days the report was working fine (taking Data Retrieval time less than 1 minute), but after some days its taking much time (increasing day by day and now its taking more than 11 minutes).
Can anybody point out what could be the reason?????
We are using,
1. SAP BI 7.0
2. SAP BO XI 3.1 Edge
3. Webi Rich Client Version :12.3.0 and Build 601
This report is made on a Multiprovider (Sales).
What are the important points that should be considered so that we can improve the performance of Webi Reports????

Data retrieval for Sony handycam with 60G harddrive.

Does BestBuy do data retrieval? I have a handycam with work video on it that accidentaly got formated. I know with a standard harddrive you can still retrieve it if there has not been recording since the formatting but I am not sure about camera harddrives. If BestBuy does not do it, does anyone know where it can be done and approximate cost. I live in the New Orleans area.
I may try the same question in computers if nobody knows. Thanks in advance for any guidance at all.

Best Buy sends out for data retrieval. You can have it sent out through geek squad to get the estimate of cost.

Data Retrieval Speed in Oracle Spatial vs. ESRI ArcSDE

I would appreciate any opinions regarding data retrieval
performance between Oracle Spatial and ESRI ArcSDE. Would an end-
user (using ESRI software) experience significant differences in
data retrieval speed depending on how the data were stored in
Oracle (MDSYS.SDO_GEOMETRY verses ESRI Binary/Blob formats).
Knowing that the ESRI binary formats are tailored to their
software front-end apps (ArcGIS, ArcMap, ArcCatalog, and
ArcInfo), wouldn't this be a "non-issue" until the spatial
dataset gets "large", and even then, wouldn't performance be
(almost) equal if the spatial indexes were created properly?
Thanks for your inputs,
Bruce

John,
You can't do that type of query in sql from sql*plus using
SDEBINARY. HOwever, you can perform spatial queries in ArcMap
if you are using SDEBINARY.
You can use the query builder to perform point-in-polygon type
queries.
Hope that helps.
For my two cents, I think SDO_GEOMETRY gives you a more robust
database to work with, because you have the added power of
Oracle Spatial functions. If you are using SDEBINARY you are
limited to only what you can do thru ArcGIS.
If you are concerned more about performance than accessibility,
especially with a large number of users, then SDEBINARY might
be the better choice.
I love Oracle Spatial and am hoping that the performance issue
will not be a serious one when we start putting ArcIMS developed
apps into production.

Passing values to subreport in SSRS throwing an error - Data Retrieval failed for the report, please check the log for more details.

Hi,
I have the subreport calling from the main report. The subreport is based on MDX query agianst the SSAS cube. some dimensions in cube has values 0 and 1.
when I try to pass '0' to the sub report as the parameter value, it gives an error "Data Retrieval failed for the report, please check the log for more details".
Actually I am using table for storing these parameter values. In the main report I am calling this table (dataset) and passing these values to subreport.
so I have given like [0],[1] and this works fine. when I give only either [0] or [1] then it is throwing an error.
Could you please advise on this.
Appreciate all and any help.
Thanks,
Divya

Hi Divya,
Based on the current description, I understand that there is no issue if you pass two values from main report to subreport, while the issue occurs when passing one value to subreport.
To narrow down the issue, I want to confirm whether the subreport can run if there is only [0] or [1] in the subreport. If so, it indicates the query statements exist error in the subreport. If it’s not the case, this shows the issue occurs during passing
values from main report to subreport. To make further analysis, please post the details of query statements of the subreport to the forum.

Slow data retrieval on 8i

I am using oracle 8i database on Windows 2000 server on compaq
proliant 350 server machine. The problem is that sometimes
connecting from a client is very slow and after connection data
retrieval is also slow. I am usring TCP/IP and net8. I came to
know from internet that there is a patch which is actually a
work around to solve this problem. Can anybody help me to locate
this patch?
Thanks in advance.
G. Rajan.

You can probably prove that this is the issue by creating a retrieve using the excel addin or smart view to replicate the form and see how long it takes to retrieve.
You will also see in the essbase app logs how long it is taking to perform the retrieve.

Data retrieval displayed on multiple pages - Servlets

I am using mysql database, JDBC and Servlets.
Could anyone tell me the best way to display the data retrieved from the database in multiple pages. For example I have 215 records and I want the data displayed in several pages with 10 rows per page.
I want something similar to these forum pages where I can move forward, back, first and last through the database.
Thanks in advance

Data retrieval after EM closed, bug?

Hello.
I think TopLink is retrieving data after EM has been closed in the case
below, and I'm not sure if this behavior is correct.
CASE: (Steps 1 to 4 and follows)
STEP 1.- I'm using a recursive table (most probably the same applies for
non-recursive tables):
create table "SA"."RECURSIVA" (
PK int primary key not null,
DATO varchar(10),
PADRE int references RECURSIVA
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (0,'Raiz',null);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (1,'n1',0);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (2,'n2',1);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (3,'n3',2);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (4,'n4',3);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (5,'n5',4);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (6,'n6',5);
INSERT INTO "SA"."RECURSIVA" (PK,DATO,PADRE) VALUES (7,'n7',6);
STEP 2.- This is the entity (please note+ the LAZY fetch type):
@Entity
@Table(name = "RECURSIVA")
public class Recursiva implements Serializable {
@Id
@Column(name = "PK", nullable = false)
private Integer pk;
@Column(name = "DATO")
private String dato;
@OneToMany(mappedBy = "padre")
private Collection<Recursiva> recursivaCollection;
@JoinColumn(name = "PADRE", referencedColumnName = "PK")
@ManyToOne(fetch=FetchType.LAZY)
private Recursiva padre;
STEP 3.- This is the data retrieval code (please note+ EntityManager is closed
before accesing data):
EntityManagerFactory emf =
Persistence.createEntityManagerFactory("mijpa");;
EntityManager em = emf.createEntityManager();
Recursiva rc = null;
rc = em.find(Recursiva.class, 7);
em.close();
while (rc != null) {
System.out.println(rc.getDato());
rc = rc.getPadre();
emf.close();
STEP 4.- Results:
n7
n6
n5
n4
n3
n2
n1
Raiz
QUESTIONS: If em is closed right after the leaf entity is retrieved:
A. How is it possible that all of the leaf ancestors up to the root are
retrieved?
B. Is toplink accessing the database after em is closed or simply the
full hierarchy is eagerly loaded at the very beginning?
C. Is this correct, or is it a bug?
NOTE: openjpa prints n7 and n6, as I would have expected.
I would appreciate your comments, specially if you think this is a bug,
in order to report it.
Thanks.
Antonio.

Data retrieval failed

Greetings all,
i'm having a problem in order to retrieve data from oracle 10g views.
Notes: Data retrieval from other tables are just fine. Some views are created for me in order to share some data from other databases. As far as i concern, we actually use the same syntax (as retrieving data from table) in order to retrieve data from view. This is my codes:
if (($_POST['barcode'] != "") || ($_POST['sname'] != "") ) {
include("conn.php");
     if (!$conn){
          echo "Error!Cannot connect to database, please try again later";
          exit;
     @mysql_select_db($db);
               $sname = strtoupper ($_POST['sname']);
               $barcode = strtoupper ($_POST['barcode']);
               $ss = strtoupper ($_POST['ss']);
               print $sname;
               print $barcode;
               print $ss;
               if ($barcode != ""){
               $stid = OCIParse($conn, 'SELECT NAMA FROM VIEW_A WHERE SEM=:ss AND BAR=:bc');
               oci_bind_by_name($stid, ":bc", $barcode);
               oci_bind_by_name($stid, ":ss", $ss);
               }elseif($sname != ""){
               $stid = OCIParse($conn, 'SELECT NAMA FROM VIEW_A WHERE SEM=:ss AND NAMA=:sn');
               oci_bind_by_name($stid, ":sn", $sname);
               oci_bind_by_name($stid, ":ss", $ss);
               $r = OCIExecute($stid);
               $row = oci_fetch_array($stid, OCI_ASSOC + OCI_RETURN_NULLS);
               if ($row==0)
     ?>
No Records!
<?php
               else
               while (($rows = oci_fetch_array($stid, OCI_BOTH))) {
     ?>
Name:: <?php echo $rows[0]; $rows['NAMA'];?>
<?php }}} ?>

I didn't understand what real problem you have?
If you missing one row of data, it's because you don't print the first row out.
If you mean that results are not ordered, then you need to add an ORDER BY clause to the queries.
PS you have a mysql call in there. Also you mix the old and new OCI function naming style.

Data retrieval buffers - buffer size and sort buffer size

Any difference to tune BSO and ASO on data retrieval buffers?
From Oracle documentation, the buffer size setting is per database per Essbase user i.e. more physical memory will be used if there are lots of concurrent data access from users.
However even for 100 concurrent users, default buffer size of 10KB (BSO) or 20KB (ASO) seems very small compare to other cache setting (total buffer cache is 100*20 = 2MB). Should we increase the value to 1000KB to improve the data retrieval performance by users? The improvement impact is the same for online application e.g. Hyperion Planning and reporting application e.g. Financial Reporting?
Assume 3 Essbase plan types with 100 concurrent access:
PLAN1 - 1000KB * 100 = 100MB 1000KB * 100 = 100MB (total sort buffer size)
PLAN2 - 1000KB * 100 = 100MB 1000KB * 100 = 100MB (total sort buffer size)
PLAN3 - 1000KB * 100 = 100MB 1000KB * 100 = 100MB (total sort buffer size)
Total physical memory required is 600MB.
Thanks in advance!

256 samples Buffer size will always give you a noticable amount of latency. If you use Software Monitoring you should try setting your Buffer to 64 samples. With the recording delay slider in the preferences->Audio you can compensate for the latency (of course not in realtime) so that the Audio will be placed exactly there, where it should hae been recorded at. In your case set it to a -value. A loopback test (check the link below) will clarify the exact amount of Latency occuring on your system.
