How to reduce the number of data blocks used by table

Hi,
I was trying to reduce the space usage of a particular table of my apex application which stores blob content and therefore deleted many records from it.
However, the data block usage remained the same as before.
I have tried to 'analyze' the table and validate the structure,but am unable to overcome this problem.
Could someone throw some light on what needs to be to reduce the number of data blocks used by this table?
Best Regards,
Priya Jetley

Priya:
It is likely that the BLOB content defined in your table is being stored 'Out-of-Line'. This means that the LOB columns are stored in segments of their own. These then are the segments that may need shrinking.

How to increase the number of data Business Object can pull for a report?

Hi,
I would like to ask around how to increase the number of data Business Object can pull for a report. I have a report which pulls data depending on the date range (ex. From 01/01/2007 - 01/10/2007). But, when the data that is pulled exceeds 5000, the report fails. Is there anyway to increase the number of data that BO can pull?
Thanks

Bobby,
to my knowledge we can't change that. Let me explain this, we have setting in the source system for DS default Data Transfer. there we will assign the processes. if you want to assign 4 you need to change the setting in the source system. For flat files we can change in BW System. We can maintain the setting in the Infopackage level(wht we are assigned in the Source System), but we can't change the process.
in order to check the setting in source system SBIW--> General Settings --> Control Parameters for Data Transfer.
we need to change here, this will effect to all the Data Sources. Before making changes check with your basis.
All the best.

Urgent HELP - How to reduce the number of entries in table MESYBODY?

Does anyone know how to reduce the number of records in synchronization table MESYBODY and MESYHEAD? The reason I wanted to reduce these tables is because I believe they have so many duplicated entries that causes extremely slow performance everytime we sync. Currently, there are almost 50,000 records for approximately 100 users, and I believe it shouldn't be that much.
We are running into a problem that it takes approximately 25-30 minutes to sync.
Any advices would be highly appreciated.
Regards,
Dai

Hi Dai,
please try to run the middleware job WAF_MW_MAPPING. For some applications (Mobile Time and Travel for example) this helps to clean the tables.

How to find the number of data items in a file written with ArryToFile function?

I have written an array of number in 2 column groups to a file using the LabWindows/CVI function ArrayToFile...Now if I want to read the file with FileToArray Function then how do I know the number of items in the file. during the write time I know how many array items to write. but suppose I want the file to read at some later time then How to find the number of items in the file,So that I can read the exact number and present it. Thanks to all
If you are young work to Learn, not to earn.
Solved!
Go to Solution.

What about:
OpenFile ( your file );
cnt = 0;
while ((br = ReadLine ( ... )) != -2) {
if (br == -1) {
// I/O error: handle it!
break;
cnt++;
CloseFile ( ... );
There are some ways to improve performance of this code, but if you are not reading thousands of lines it's quite fast.
After this part you can dimension the array to pass to FileToArray... unless you want to read it yourself since you already have it open!
Proud to use LW/CVI from 3.1 on.

How to reduce the number of bytes for a picture

I want to reduce the number of bytes used for a picture to be sent to a site like Ebay or craigslist. I son't see any options in Iphoto for this purpose.

You can do it in Preview.
Open the image in Preview. Under Tools, click Adjust Size.
Scale it down to the smallest acceptable size (the website should give a suggested resolution).
Then go to File -> Export, save it as a Jpeg.
Smaller size image means smaller file size.

How to retrieve the number of "free" rows in a table?

Hi,
if in a client only environment (no sync to mobile server) rows are inserted and deleted into a table,
is there a way to retrieve the number of "free" rows in a table? Number of "Free" rows stands for
number of rows that can be inserted again, before the table extents in size.
Is there a way in OLite 10.3.0.2.0 to retrieve the size of tables and indexes? ALL_TABLES is not
a place that really works.
Best regards and many thanks,
Gerd

Hi Gary,
many thanks, the partner uses a Lite client db without sync. The db runs inside an laboratory device and collects measures. There must be a way to estimate the the number of "measures" rows, that stil can be stored in the db.
Than we need to make the deleted space available for new rows. The partner tested defrag.exe and found that it
needs very long time to run, especially if the db is bigger than 2GB. ... and that this run sometimes fails.
Is there any recommendation the partner can follow on?
Thanks,
Gerd

How to count the days between Date Range using OO ABAP?

hi experts,

Not sure I understand the requirement for it to be OO, but you could always write your own (i.e. use this):
REPORT zz_date_diff.
CLASS date_diff DEFINITION.
PUBLIC SECTION.
    METHODS diff IMPORTING     i_date_fm TYPE d
                               i_date_to TYPE d
                 EXPORTING     e_days    TYPE i.
ENDCLASS."
CLASS date_diff IMPLEMENTATION.
METHOD diff.
    e_days = i_date_to - i_date_fm.
ENDMETHOD."
ENDCLASS."
DATA: g_ref TYPE REF TO date_diff,
      g_days TYPE i,
      g_date_fm TYPE d VALUE '20080101',
      g_date_to TYPE d VALUE '20090101'.
START-OF-SELECTION.
CREATE OBJECT g_ref.
CALL METHOD g_ref->diff
    EXPORTING
      i_date_fm = g_date_fm
      i_date_to = g_date_to
    IMPORTING
      e_days    = g_days.
WRITE g_days.

How to reduce the number of DB calls in Biztalk Map

Hi,
I am using the
1. first scripting Functoid(calling External Assembly) to fetch the details from DB as comma separated values(1,2,3)
2. Scripting Functoid to apply Inline XSLT temple(which will pick the comma separated value and place it as three different records)
Instance messages
All the items are working as expected but, the call to DB is happening for each record in the details.
if my input has n number of details section, the database call is happening n times, which is drastically reducing the performance.
I wanted to make it as one DB call . Please suggest
Regards, Vignesh S

Hi,
You can also use the Blogical BizTalk Database lookup functoid with caching feature.This functoid can be used like the
Database lookup functoid that ships with BizTalk. It will execute a query against a given database and cache the result using the
System.Web.Caching.Cache with a sliding expiration of one minute.

How to reduce the number of exchange between the database & the app?

Hi,
In order to resolve performance issue of my application under a dirty network (ping=150ms), I make use of Ethereal.
And I noticed that an incredible amount of TCP exchanges (little SQL requests amoung others things) was complete between my application and the database.
Does exist a KODO or JDO parameter upon which I could work around in order to optimize these exchanges/SQL requests?
DB: Oracle 9.2.0.1 --
KODO: 3.3.3 --
Thanks a lot.

You can activate logging of every SQL being issued by Kodo by setting kodo.Log:SQL=TRACE.
Kodo issues SQL when the application accesses object fields/relations that are not yet loaded. Analysis of SQL would indicate what is being fetched. You can minimize the number of SQL, say, adding a set of fields in the same fetch-group thereby bringing them from database in a single SQ!L call.

How to find the value of date char used as exception aggregation reference

Hi BI Gurus,
On a BEx report I need to list three things by material:
1)   the open (not yet delivered) Purchase Order quantities
2)   the PO quantity to be delivered next and
3)   the date that belongs to the next delivery
The model supports these data i.e. for each material I can list all open quantities by Purchase Order / Item / Schedule line and the scheduled delivery dates are also available as a characteristic.
Determining 1) is easy as the drilldown is fixed (materials only) the open quantities get summarized for all PO-s belonging to the materials.
To determine 2) I used a Calculated KF simply including KF 1) =Open PO Qty in the definition and setting Exception Aggregation (first value) with a reference char of the delivery date. This gives back the Open PO Quantity to be delivered first.
My question is about how to determine the 3rd value (actually this is not a KPI but a characteristic value). In other words, for each materials I would need to determine the first among all of the possible delivery date char values of the open PO Items / schedule lines. This is the date the quantity shown in the 2nd KPI will be delivered on.
Does anybody have an idea how to approach this issue?
Thanks for you help in advance,
Attila

Hi Olivier,
Thanks for your suggestion. I got a bit closer with the replacement path formula variable and the CKF. I tried to apply the same logic of KPI 2) but for some reason it did not work. Actually, it delivers the right value but only when 0SCL_DELDAT (Scheduled delivery date) is in the drilldown But what I need is the first delivery date by Material only, and without this 0SCL_DELDAT drilldown.
Any other ideas?
Thanks and bye,
Attila

How to restrict the number of batch jobs used by middleware?

Hi,
I'm using middleware to replicate data which send IDOCs from one system to another. I know on source system, I can use SMQS to restrict the number of connections. But on target system, can I use any tool to restrict number of batch jobs? Because every time when replicating data, all batch jobs are occupied.
Thanks a lot!
