Filesize a problem when uploading a file to Oracle via JDBC?

Hello,
I am trying to upload a file via JDBC to an Oracle Database (into a BLOB field). The file is converted to a byte array for uploading.
While processing the request the following error is thrown :
[31.08.05 09:58:33:151 CEST] 40cc40cc SystemErr R Caused by: java.sql.SQLException: Datengr��e gr��er als max. Gr��e f�r diesen Typ: 485323

A blob is able to hold files with gigabyte size, a simple 460k file should not cause this JDBC error. I had a test with a 127k file, too, same error (different file types tested: html, doc, pdf, ...). Is this a problem of the driver or is there anythig I am doing wrong?
Many thanks in advance for your help,
Rommie.

My problem is not to retrieve the file but to upload
it. I checked the examples and only saw examples for
retrieving a BLOB or CLOB, but not for inserting it
into the database
Maybe I am blind ... if so, please publish your link
to the example.The page at:
http://www.oracle.com/technology/sample_code/tech/java/sqlj_jdbc/files/advanced/advanced.html
Has a subsection that reads:
LOB Datatype [19-Feb-2003]
The term large object (LOB) refers to a data item that is too large to be stored directly in a database table. This sample application demonstrates how to read and write LOB datatype.The Oracle JDBC drivers provide support for two types of LOBs: BLOBs (unstructured binary data) and CLOBs (character data). BLOB and CLOB data is accessed and referenced using a locator stored in the database table.

The zip is a standalone Java application that will create any needed tables, populate them with example data (both LOBs and CLOBs) from the data files in the zip and then put up a Swing gui that will allow you to add additional LOB and CLOB data to the table. Everything is there, the readme explains the 2 properties files you need to edit. The only other thing besides reading comprehension that you need to supply is DB connection information with the necessary privileges.
The Source link is a link to the main code, but does not include all the code in the package. However, it contains the code to write CLOBs and BLOBs into the database.
The Readme explains everything. It also has code excerpts, including the code used to read the sample data from file and write it into the LOBs and CLOBs.

A strange problem when uploading a file in Struts

When i upload a file, the other elements in the form of the jsp cannot be got by the ActionForm, instead, the getters show that they are "null"s. But when i upload no file, everthing is ok.
Moreover, the problem happens when i update an article which can have an picture with it, but when i add a new article, the problem does not appear, instead, the file can be uploaded and other element can also be got.
i think i might be a problem of the volume of the request , because i put more information to update than to add.
Hope someboby can help me with the problem.

Problem when uploading CSV File

Hi, i'm testing some changes i made to an infoprovider and something strange is happening to me (as usual) I have a CSV file that is uploaded into BI from my PC and I tested this file with 100 records, later i deleted 98 records so i can test the file with fewer records in order to analyze the formulas in BEx with some very specific data. Now here is the strange part: even though i modified the file and left only 2 record in it, when I run the DTP the system is still uploading 100 records!?! How can that be possible. I checked everything, the datasource and the infopackage are both pointing to the same file (the one which has two records) and there is no other file in the entire hard drive that has 100 records and/or the same name/structure that the file i'm uploading into BI. I just can't figure out why the DTP is uploading more records that I have in the CSV file!?. Any ideas??
Another thing: I'm having problem with 0calmonth, tried everything. I put the calmonth in the CSV file in both formats MMYYYY (092010) and YYYYMM (202009) but I still get error when running the DTP. I have activated/deactivated the conversion routine in the transformation and in the datasource, I change the field length in datasource and tried any possible combination of these changes and I still can't make it work. I searched here and read all the post related to this issue but i still can't figure out how to properly upload information into 0calmonth.
Regards, Mauro

pls check the data in PSA.... you may be loading only 2 records..
Also possible that the DTP is set to load FULL data.... so its loading the entire data from PSA (old + new)
the calmonth format should be YYYYMM... what is the error message u r getting... you can always check the PSA and see whats the format coming there

How to avoid the split problem when uploading the data from csv file

Dear Friends,
              I have to upload data from the .csv file to my custom table , i have found a problem when uploading the data .
i am using the code as below , please suggest me what i have to do in this regard
      SPLIT wa_raw_csv AT ',' INTO
                wa_empdata_csv-status
                 wa_empdata_csv-userid
                 wa_empdata_csv-username
                 wa_empdata_csv-Title
                 wa_empdata_csv-department.
APPEND wa_empdata_csv TO itab.
in the flat file i can see for one of the record for the field Title as
Director, Finance - NAR............there by through my code the wa_empdata_csv-Title is getting splited data as "Director, and Department field is getting Finance - NAR" , i can see that even though " Director, Finance - NAR" is one word it is getting split .
.......which is the problem iam facing.Please could any body let me know how in this case i should handle in my code that this word
"Director,Finance - NAR"   wil not be split into two words.
Thanks & Records
Madhuri

Hi Madhuri,
Best way to avoid such problem is to use TAB delimited file instead of comma separated data. Generally TAB does not appear in data.
If you are generating the file, use tab instead of comma.
If you cannot modify the format of file and data length in file is fixed character, you will need to define the structure and then move data in fixed length structure.

Problem when uploading a large file in PI - weird SQL I/O errors

Hi guys,
I'm facing a very difficult problem when uploading a 35 MB with an FTPs adapter. I see in the logs that, after the translation to XML, it's going to 170 MB.
I receive the following error in the CC Monitoring:
Error: com.sap.aii.af.ra.ms.api.DeliveryException: Problem inserting 41827ca7-6b8c-4a87-198d-ad8a81fcb12b(OUTBOUND) into the database: com.sap.engine.services.dbpool.exceptions.BaseSQLException: Connection is invalid.
When I look in the NWA Monitoring, I see the following details:
SQL error occurred on connection affhb201:X11:SAPSR3DB: code=17,002, state="null", message="Io exception: Socket closed";
SQL statement is "INSERT INTO "XI_AF_MSG" ("MSG_ID","DIRECTION","MSG_BYTES","TIMES_FAILED","SENT_RECV_TIME","STATUS","CONN_NAME","MSG_TYPE","REF_TO_MSG_ID","ADDRESS","TRANSPORT","CREDENTIAL","TRAN_HEADER","MSG_PROFILE","CONVERSATION_ID","SCHEDULE_TIME","PERSIST_UNTIL","FROM_P........
I cannot check the Visual Admin Logs 'cause I don't have access to them yet.
I'm pretty convinced that some swap memory, message size or whatever setting on the adapter engine or on the Java stack is preventing this. I do not get any message in CC Monitoring when uploading a smaller, 6 MB version of the same file.
Can you please help me solve this or give me some interesting pointers?
Never before did we experience something like this in the PI system. In addition, I didn't find any useful resource on the SDN and throughout the SAP notes for this.
Let me know if you need more info about this.
Best regards,
George

Hi George
I am facing the same issue, where did you configure the message split in the Communication Channel?
If I do the message split as you said, is it going to create several files or how does it work?
Thanks in advanced

Code doesn't update when uploading new files to website.

code doesn't update when uploading new files to website. I was using an old DW version for a long time then forced to upgrade when I bought my MacBook Pro. Now when I make changes to my pages and link to new files etc on my harddrive, when i upload the pages it won't image because the code still points to harddrive (this did not used to be a problem)... I manually changed the code on the web host site to point to the site and it loaded fine. But now my files on my harddrive also point to the web host files and now don't image on my computer. I never had to worry about this so far and wonder if the new version has a setting I'm supposed to be aware of so that I can design on my hardrive and upload and it knows that the files are being uploaded with it? Ugh hpe this makes sense - I'm NOT a webs designer and the new DW is way more than I use in it's technology.

Hi
This sounds like you have not defined your site in the site definition.
Follow the steps in these 2 tutorials to set-up your site locally and for the remote server -

How do I change the default folder that opens when uploading a file to the internet from my mac? (at the moment it automatically defaults to 'Downloads' folder)

How do I change the default folder that opens when uploading a file to the internet from my mac? (at the moment it automatically defaults to 'Downloads' folder)
For example...
I am on a webiste and wish to upload a photo.
I click on select file on the website
Finder opens and defaults to 'Downloads' folder (it happens with all wesbites)
How do I change this?

You are attempting to download the picture to your computer not uploading photo to the website if I am understanding you correctly.
To change the download direction, you must do so through your browser's Preferences. If you are using Safari, hopefully, someone who uses Safari will help you and/or post over in their forums. I do not use Safari.

Problem with uploading a file in Clustered Environment

Hi,
I have a problem with uploading a file in a clustered environment. I have an iview component which facilitates an upload action of an xml config file. The problem is that the upload of the modified XML file is reflected only in the central instance of the cluster and not in the dialog instances. The dialog instances hold the old config file.
Is there any solution to upload the file to all the nodes in the cluster.
Thanks
Kiran

Hi,
This is a known problem with clustered environment. Remember that your portal component runs on just on dialog instance and it doesn't automatically have access to the other nodes. However, there are some ways to get around this
1. Use KM to store files. KM is a common repository for all application servers and therefore you needn't worry more
2. Use an external batch oriented product (suresync/robocopy) to synch folders on the different DIs. You basically use your existing portal component, but there is a batch job which makes sure the upload folder is identical on all DIs (however, there is a slight delay depending on how often you run the batch job)
3. Store the files on a shared disk directly from the portal component.
Cheers

In debuggin mode, i can see the itab uploaded with xml payload. But in that same place, the hexadecimal format has double zeros 00 after each character.
XML message : <?xml

This makes the resultant xml invalid.
can anyone help me to solve this?

Problem when upload legacy data

Hi all,
I've faced a problem when uploading asset legacy data (AS91) for customer. My customer have started depreciation on May 21, 2009, and I set transfer date is November 30, 2010. So SAP doesn't calculate right planned value for December, 2010. I think that problem related to the first month depreciation. It calculated full month for depreciation (instead of from May 21) and change the planned value for December 2010. So I want SAP just calculate 11 days depreciation for May 2009. How can I config to do this?
Thanks in advance!

Hi,
Check in the asset master Opening Start Date for depreciation.. If it is under open mode change that date and see asset explorer for depreciation values.
Thanks,
Padmaja

I use windows 7, and also have available Adobe Reader 5 and Adobe Reader X, but i receive some problems when reading pdf files. What can I do???

Reader 5 is not Windows Compatible. Two different versions of the same computer can cause all sorts of problems. Remove all Acrobat and/or Reader software then re-install Reader X.

Upload text file to oracle table with checking and aggregation

Hi Friends,
I am new to ODI. I have encountered a problem which is specific to ODI 11G (11.1.1.6.3) to upload text file to oracle table with checking and aggregation. Would you please teach me how to implement the following requirement in ODI 11G?
Input text file a:
staffCode, staffCat, status, data
input text file b:
staffCodeStart, staffCodeEnd, staffCat
temp output oracle table c:
staffCat, data
output oracle table d:
staffCat, data
order:
a.staffCode, a.staffCat, a.status
filter:
a.status = ‘active’
join:
a left outerjoin b on a.staffCode between b.staffCodeStart and b.staffCodeEnd
insert temp table c:
c.staffCat = if b.staffCat is not null then b.staffCat else a.staffCat
c.data = a.data
insert table d:
if c.staffCat between 99 and 1000 then d.staffCat = c.staffCat, d.data = sum(c.data)
else d.staffCat = c.staffCat, d.data = LAST(c.data)
Any help on fixing this is highly appreciated. Thanks!!
Thanks,
Chris

Dear Santy,
Many thanks for your prompt reply. May I have more information about the LAST or SUM step?
I was successful to create and run the following interfaces p and q
1. Drag text file a to a newly created interface panel p
2. Filter text file a : a.status = ‘active’
3. Lookup text file a to text file b : a.staffCode between b.staffCodeStart and b.staffCodeEnd
4. Drag oracle temp table c to interface panel p
5. Set c.staffCat : CASE WHEN b.staffCat IS NULL THEN a.staffCat ELSE b.staffCat END
6. Set c.data : a.data
7. Drag oracle temp table c to a newly created interface panel q
8. Drag oracle table d to interface panel q
9. Set UK to d.staffCat
10. Set Distinct Rows to table d
11. Set d.staffCat = c.staffCat
12. Set d.data = SUM(c.data)
However, the interface q should be more than that:
If c.staffCat is between 99 and 1000, then d.data = the last record c.data; else d.data = sum(c.data)
Would you please teach me how to do the LAST or SUM steps? Moreover, can interface p and interface q be combined to one interface and do not use the temp table c? Millions thanks!
Regards,
Chris
