Rows per batch and DefaultbufferMaxrows

Hi,
What is the difference between rows per batch and DefaultbufferMaxrows in data task? Is there any relation between these two?

Rows per batch : It is the number of rows fetched under single operation to optimize the query plan.The rows per batch should be as close to to total amount of records in your source table.
The default value for this setting is -1 which specifies all incoming rows will be treated as a single batch. You can change this default behavior and break all incoming rows into multiple batches. The allowed value is only positive integer which specifies
the maximum number of rows in a batch.
DefaultBufferMaxRows : Defines the maximum number of rows in each buffer, by setting the
DefaultBufferMaxRows property. The default maximum number of rows is 10,000.

Rows per batch and Maximum insert commit size

Have been reading various post to understand what the properties 'Maximum insert commit size' and 'Rows per batch' actually do and am confused as each have their own explanation to these properties. As far as I understood, MICS helps SQL server engine to
commit the number of rows specified to it and RPB is to define the number of rows in a batch?
In case I set the property to say RPB - 10000 and MICS - 5000, does this mean the input data is fetched in a batch of 10000 and each time only 5000 are committed?
What happens in case of RPB - 5000, MICS - 10000. Are the batches formed for each 5000 records and committed for each 10k records?
One post mentioned on RPB being merely a property to help SQL server device a optimal plan for data load. If this is true then why have the MICS property? Instead RPB can be assigned a value and engine decides on what is best load method it wants to use.
Thanks!

Hi Rohit,
Maximum insert commit size specify the batch size that the component tries to commit during fast load operations. The value of 0 indicates that all data is committed in a single batch after all rows have been processed. A value of 0 might cause the running
package to stop responding if the component and another data flow component are updating the same source table. To prevent the package from stopping, set the Maximum insert commit size option to 2147483647.
Rows per batch specify the number of rows in a batch. The default value of this property is –1, which indicates that no value has been assigned.
For more details about those two properties, please refer to the following document:

Limit rows per page, include spacer and format last row on page break

Hello,
I am new to BI and would like some help with an issue I don't seem to be able to resolve?
I have a table that uses two xml group elements (2nd nested inside first) to produce my detail lines.
Example:-
First for-each loop runs over shipto details and within this another for-each loop runs over items related to that shipto, all of which results in multiple detail lines.
I need to limit the number of rows per page and should the data roll over to the next page I need to place a horizontal closing border on the first page's table (only using column borders).
Also when the data does not fill the page I need to add spacer rows to the page limit?
I have tried using examples found in these forums, position(), counters etc… but due to having the second detail loop I’m unable to get these working or I’m doing something wrong?
Your help would be greatly appreciated.

Hi BIPuser, thanks for the links.
I have tried some of the examples which I can get working with a single level of detail lines. However when I add the second level of detail lines the position() function seems to fail as my rowlimit appears to be ignored.
I am also unable to get the $lpp example working because the outer detail loop may only have one xml element and therefore BI assumes only one line is to be printed when in fact the inner xml element detail loop may have further multiple lines. I need to effectively count the outer & inner loops as one to determine the number of lines being processed.
Example of xml - My table for detail lines needs to include both ShipTo & item number lines grouped as shown, thereby counting & outputting 7 lines in this instance.
<INVOICE>
<On_Ship_To_S23> Outer loop
<On_itm_num_shr_row_S21> Inner Loop
<On_itm_num_shr_row_S21>
<On_itm_num_shr_row_S21>
</On_Ship_To_S23>
<On_Ship_To_S23>
<On_itm_num_shr_row_S21>
<On_itm_num_shr_row_S21>
</On_Ship_To_S23>

How to pivot horizontally Author names, and group by Book title. One row per book with multiple authors

I have 3 tables - Book, Author, BookAuthorReference
A book can have multiple authors, and when I do straight query I get multiple rows per book
SELECT <columns>
FROM Book b, Author a, BookAuthorReference ba
where ba.BookId = b.BookId and
ba.AuthorId = a.AuthorId
I want to get the results as ONE row per book, and Authors separated by commas, like:
SQL 2008 internals book    Paul Randal, Kimberly Tripp, Jonathan K, Joe Sack...something like this
Thank you in advance

This can by done by straying into XML land. The syntax is anything but intuitive, but it works. And moreover, it is guaranteed to work.
SELECT b.Title, substring(a.Authors, 1, len(a.Authors) - 1) AS Authors
FROM   Books b
CROSS APPLY (SELECT a.Author + ','
FROM   BookAuthorReference ba
JOIN   Authors a ON a.AuthorID = ba.AuthorID
WHERE ba.BookID = a.BookID
ORDER BY ba.AuthorNo
FOR XML PATH('')) AS a(Authors)

Set Maximum Rows Per Page not working

I want to display 50 rows per page and I tried the below but still I can see the default 15 rows per page.
Home>Application Builder>Application 301>Page 51>Interactive Report Attributes>Search Bar>Maximum Rows Per Page
Set to = 50
Home>Application Builder>Application 301>Page 51>Interactive Report Attributes>Search Bar>Rows Per Page Selector
Removed the check mark and still shows 15 rows per page.

Run your report. Set the Rows to 50. Press Go. Select 'Save Report' from the 'magic wheel' menu and next select 'Save as default report settings'.
It is a rather long way, but seems the only one...

Writing large xmltype data to UTL_FILE and setting max row per file

Hey Gurus,
I am trying to create a procedure (in Oracle 9i) that writes out xml data I have created into several xml files (file would probably be to large for one xml file output...I am doing this for 270,000 rows of data), setting the max rows to 1000 rows per file. I know one would have to create a looping contsruct to do this but I am just not adept enough in PL/SQL to figure it out at the moment.
So essentially their would be some sort of loop construct and substr process that creates a file after looping through 1000 rows and then continues the count and creates a another file until all 270 xml files are created. Simple enough right...lol? Well I've tried doing this and haven't gotten anywhere. My pl/sql coding skills are too elementary I am guessing. I've only been doing this for about three months and could use the assistance of a more experienced person here.
Here are the particulars...
This is the xmltype view code that I used to create the xml data.
select XMLELEMENT("macess_exp_import_export_file",
XMLELEMENT("file_header",
XMLELEMENT("file_information")),
XMLELEMENT("items",
XMLELEMENT("documents",
(SELECT XMLAGG(XMLELEMENT("document",
XMLELEMENT("external_reference"),
XMLELEMENT("processing_instructions",
XMLELEMENT("update", name)),
XMLELEMENT("filing_instructions",
XMLELEMENT("folder_ids",
XMLELEMENT("folder",
XMLATTRIBUTES(folder_id AS "id", folder_type_id AS "folder_type_id")))),
XMLELEMENT("document_header",
XMLELEMENT("document_type",

XMLELEMENT("document_file_path", document_file_path),
XMLELEMENT("document_extension", document_extension)
))))from macess_import_base WHERE rownum < 270000))))AS result
from macess_import_base WHERE rownum < 270000;

How to check the time taking to extract rows from source and time load data into destination

Hi,
Recently I have started working on Optimizing an SSIS package in 2012. The package reads data from AS 400 server and load into SQL Server table.. No transformations are being used in the package. only ADO.Net Source and OLE DB Destination are using in the
package.
The SSIS package is extracting 6500 rows and loading into database per batch. This process is taking 18 seconds. I would like to know out of 18 secs how much time is being used only to extract data from the source and how much time is taking to write the
data to the database per each batch.
Any thoughts be greatly appreciated...
Thanks,
Venu.

Hello
We need more information regarding your system. If you are using SQL 2014 then you can use the new DMV
sys.dm_exec_query_profiles which is doing this exactly. Check out this URL: http://msdn.microsoft.com/en-us/library/dn223301.aspx
While executing your SSIS project you can examine each and every process and get the percentage it already did and all the information regarding it.

How to set number of rows in "Rows Per Page Selector" in Interactive Report

Hi Guys,
Is there any way to set the number of rows in "Rows Per Page Selector" in Interactive Report. By default it is set to 15.
I know one way is to change the number of rows when you are running the report and then set that as 'Default Report Setting'.
If anybody is aware of any other way, please let me know.
Cheers,

Hi Pavel,
can you please specify your question more clearly. If you are on NW 7.0 you can determine a number of colums for your filter item with following command:

How to set the number of rows per page dynamically

Hello all,
i urgent need the option to set the number of rows per page dynamically.
I've got a parameter.
In dependence of the value of this paramter i want to set the number of rows per page of a repeating frame.
The Reports Builder version i use is 10.1.2.0.2
I defined a report trigger.
My code so far:
function R_G_BEMERKUNGFormatTrigger return boolean is
begin
if :vYN_Display_one_per_page = 'Y' then
--what i've to write right here??
return (TRUE);
else
     return (TRUE);
end if;
return (TRUE);
end;
Can anyone help me please??
Best regards
Florian

Do you just need to change back and forth between 1 and some other number? If so, you can create two identical layouts, one with the "number of rows per page" preperty (on the repeating frame) set to 1 and the other layout set to whatever. You would have to have duplicate layouts for each group you wanted to do this with. Your format trigger on the outermost master group frame where num of rows was 1 would look like:
function M_G_ename_GRPFRFormatTrigger return boolean is
begin
if :vYN_Display_one_per_page = 'Y' then
    return (TRUE);
else
    return (FALSE);
end if;
end;Your format trigger on the outermost master group frame where num of rows was whatever would look like:
function M_G_ename_GRPFR1FormatTrigger return boolean is
begin
if :vYN_Display_one_per_page = 'N' then
    return (TRUE);
else
    return (FALSE);
end if;
return (TRUE);
end;

How I show only 20 rows per pages in a rtf report in BI Publisher 11g

I'm making a report and i want show only 20 rows per pages in a formatt RTF. I get this with anything as a xls, xslt....
I'm a new user....please . Any idea..???
Thank for all.
Edited by: 844565 on Mar 15, 2011 7:34 AM

Instead of doing that take the url CURRENT_SERVER_URL(pre-definde BI Publsiher variable) by declaring like below
<?param@begin:CURRENT_SERVER_URL?>
Then subsequently add the extra patameters eg. region like below
{$CURRENT_SERVER_URL}Data/Country.xdo&p_region={REGION} <- get this REGION value from XML

Hacking application id equals() to allow more than one row per "primary key"

I have a read only entity whose primary key is not the real primary key
on the underlying table. The result is that I get more than one row per
"primary key". This is what I want. However KODO will not allow me do
it, because I am storing the collection in a HashSet() and the equals()
method on the application id object ensures that this set contains no
duplicates (as defined by the application id). At least thats how it
seems to behave.
So, I have hacked the equals() method to do this:
public boolean equals (Object ob)
if (this == ob)
return true;
// Doing this because we expect more than one row from
// REF_CODES for the same domain/shortCode combination.
// This is ok to do (I guess?) as long as we are only
// doing selects using this class.
return false;
Will this hack have any side effects? Is there another option? Like
using a list collection? Is so, which collections are supported?
Thanks,
Mike.

The "primary key" I am using it already a compound key of two columns.
The real key on the underlying table is a three column key. But the
problem is that the table represents two different application level
entities. I could deal with it when I was hand-writing SQL (I could do
a distinct for example) but now I am relying on foreign key
relationships since I moved to JDO. Not sure what to do. Best solution
is to rework the table, but there is a lot of legacy code (that other
teams use and maintain) relying on this table. I guess I'll use the
weekend for inspiration ;-)

This sounds like a dangerous operation. Even if this works now, I
cannot promise future compatibility... and in fact may result in bad
data (for example in caching both at the PM and PMF level) Is there no

Keys can be multi columned (e.g. last_name, soc_sec_number)

NEXT button on report portlet shows 10 rows-maximum rows per page=9999

I created a report with the DB Provider portlet. I set the maximum rows per page to 9999 when displayed as a portlet and as a full page. I put the portlet on a page and it only shows 10 rows and then the next button.
If there are exactly 10 rows I get the next button. If I click it the next page loads with no data. If there are less than 10 rows there is no button.
If I create a new portlet it does not do this. I'm only having the problem with one portlet now but I've seen it in the past. I usually just build the portlet again but I would like to know how to fix it.
I can't customize the portlet because of bug #3467032.

Select customize and set the number of rows to 9999. I'm guessing that it's currently set to 10.

Rows Per Page doesn't affect the number of records displayed

I just updated from 3.2 to 4.0 this morning. When I change the Rows Per Page value in the action menu the report doesn't change and the number of records displayed stays at 10. The report has ~6000 records. I edited the report attributes and add the rows selector to the IR search bar. This doesn't change the behavior either. I noticed that if I change the rows per page in the action menu then the drop down select list is updated, but the report still doesn't change from 10. I tried paging to the next set of results and it still remains at 10.
Has anyone else experienced this problem?
Tony

Yes, Tony, I've seen this in several versions of APEX. In most cases, simply starting a new session was enough to force APEX to refresh the page and grab the new set of pagination directives. If that doesn't work, please give more info like: what type of report you are doing and what the Pagination values are. Please note the following:
Report Template
Pagination Scheme
Enable Partial Page Refresh
Display Position
Number of Rows/Number of Rows Item
Maximum Row Count
