File Adapter determining file size

I have added a Header Variable to my Receive activity so that I can capture the size of the file coming in. I've also added a "size" element to the InboundFileHeader.wsdl.
I can't figure out how to populate that header variable! I was hoping it would just be populated automatically since I've added the element to the wsdl but no such luck, just null variables.
Thanks.

In 10.1.3.1 it does shows up as header variable, but fileadapter wsdl file has only filename and directory name as element.
I have not tried to modify adapter wsdl file, but here is little hacky way to get the size:
Let's your header variable is Variable_FileHeader, please defined two string variables naemd Variable_Header_String and Variable_Size, and doing following assign operation you should be able to get the file size.
<copy>
<from expression="ora:getContentAsString(bpws:getVariableData('Variable_FileHeader','/ns3:InboundFileHeaderType'))"/>
<to variable="Variable_Header_String"/>
</copy>
<copy>
<from expression="substring-before(substring-after(bpws:getVariableData('Variable_Header_String'),'<size>'),'</size>')"/>
<to variable="Variable_Size"/>
</copy>

How to determine the size of a flat file attachment in a mail sender cc?

Hi
I use PI 7.11
I have a scenario where a flat file attachment is being picked up by a MailSender adapter and if the size of the attached flat file is larger that 500 bytes the receiver is A and if the attachment is less that 500 bytes the receiver is B.
I have checked the Context Object list in the Conditions section of Receiver Determination, and it seems, that only the file adapter allows for validation on the file size.
I contemplated an extended receiver determination but the attachment is a flat file which just needs to be passed thru without being converted to an XML document, so my source document is not of XML format.
An other but not very nice way would be to use an intermediate folder to drop the attachment in and from there use a file sender adapter and thus get access to the filesize attribute in my receiver determination, but I would like to avoid this.
Any suggestions?
BR MIkael

Hi
I have decided to make a module, where I plan to place the size of the attachment in the Dynamic Configuration variable "ProcessStep", but to my surprise, it seems that all the context objects in the receiver determination condition section are of type String and hence it is not possible to make a condition where I test for whether the value is smaller than say 500!? Only equal, NOT equal and LIKE are available (EX seems to be disabled as this probably only works in an xpath.
Would one way be to use the xpath expression like this ns1:Main\ProcessStep < 500 where ns1: http://sap.com/xi/XI/System?

File Adapter Polling issue(Is there critical value of File size )?

Hi
I use File adapter as the Activation to initialize a BPEL process instance .The source data is a kind of Delimited file format.On my PC, when the file size is less than 4M ,everything works fine ,But when the size increased. The BPEL process will not initialize the instance.When the source data is XML data , the "critical value " is about 12M. The error msg is below.

how can i solve this problem?can i predeploy some parameter? Is there some critical value of File size for the processing of File Adapter ?

Hi,
There is no specific parameters to specify the maximum file size to be read in. It is just limited by the heap size of the JVM running the BPEL engine.
If you have enough RAM on your machine you can change the current heap size from 512Mbyte to 1Go by editing the startorabpel.bat file
and modifying the line :
set MEM_ARGS=-Xms512m -Xmx512m -Xmn300m -XX:MaxPermSize=80m
to
set MEM_ARGS=-Xms512m -Xmx1024m -Xmn300m -XX:MaxPermSize=80m
But only do it if you have at least 1.5 Gb of RAM on your machine, otherwise ot will keep spawing and you will have very bad performance.
Speaking about performance, do you really need to have a BPEL payload of 4 to 12 Mb ?
Will the BPEL process really need to access it ? if so, the best solution would be using batching techniques to cut you file in pieces and process it piece by peice.

Sender File adapter Pooling interval & file Size issue

Hi ALL,
I have a file size of 400 MB to be picked to be the sender file adapter i am facing issue that the system is unable to even pick the file and place in the Q for Processing.
1)we have no mapping no content conversion ....only pick the file from one loaction and place it in 3 different locations with 3 different names ...can any one help me in solving this .. ? the best workable method to achive this .
2) this file is getting created once in a day .say 2 PM .so i can give the poll intravel to 24 hours ..but some times ..the file creation in server gets delayed ..but they cont wain for the next 24 hour to come for processing the file ..so my query is can we reduce the poll intravel for 2 PM till 3PM hour for some 3 times ..and once it reches 3PM it can poll as usual with a gap of 24 hour time ..
thanks
RK

Hi Rupash,
>>I have a file size of 400 MB to be picked to be the sender file adapter i am facing issue that the system is unable to even pick the file and place in the Q for Processing.
Never use File adapter for picking large file (maximum size which I have seen it to work successfully is 200 MB)
Instead go for Java proxies. Check this forum post for the discussion:
Java proxy to use XI as a file mover

Receiver FTP Adapter File Size Splitting

Hi,
I am receiving an IDoc from R/3 into XI.
I then map this IDoc into an xml file and use a receiver ftp adapter to drop the files onto a ftp server.
Is there anyway, that I can use the adapter to split the message interface into smaller files. For example, if I were to ftp the message interface into 1 file, the file size would be 1MB. I would like to split the 1 message interface into 4 x 250kb files without having to split the message interface?
Thanks,
Miguel

Hi,
If you split into 4 files each one should be a XML file right?
This is possible without BPM.
Go thro the blog:
/people/jin.shin/blog/2006/02/07/multi-mapping-without-bpm--yes-it146s-possible
Wat u need to do is make the target side 0..unbounded. If u have 100 records, Map some 25 records in first occurence, 25 in second and so on. This way u can reduce file size.

P.Venkat

FILE and FTP Adapter file size limit

Hi,
Oracle SOA Suite ESB related:
I see that there is a file size limit of 7MB for transferring using File and FTP adapter and that debatching can be used to overcome this issue. Also see that debatching can be done only for strucutred files.
1) What can be done to transfer unstructured files larger than 7MB from one server to the other using FTP adapter?
2) For structured files, could someone help me in debatching a file with the following structure.
000|SEC-US-MF|1234|POPOC|679
100|PO_226312|1234|7130667
200|PO_226312|1234|Line_id_1
300|Line_id_1|1234|Location_ID_1
400|Location_ID_1|1234|Dist_ID_1

999|SSS|1234|88|158
I would need a the complete data in a single file at the destination for each file in the source. If there are as many number of files as the number of batches at the destination, I would need the file output file structure be as follows:
000|SEC-US-MF|1234|POPOC|679
100|PO_226312|1234|7130667
200|PO_226312|1234|Line_id_1

Ok Here are the steps
1. Create an inbound file adapter as you normally would. The schema is opaque, set the polling as required.
2. Create an outbound file adapter as you normally would, it doesn't really matter what xsd you use as you will modify the wsdl manually.
3. Create a xsd that will read your file. This would typically be the xsd you would use for the inbound adapter. I call this address-csv.xsd.
4. Create a xsd that is the desired output. This would typically be the xsd you would use for the outbound adapter. I have called this address-fixed-length.xsd. So I want to map csv to fixed length format.
5. Create the xslt that will map between the 2 xsd. Do this in JDev, select the BPEL project, right-click -> New -> General -> XSL Map
6. Edit the outbound file partner link wsdl, the the jca operations as the doc specifies, this is my example.
<jca:binding />
        <operation name="MoveWithXlate">
      <jca:operation
          InteractionSpec="oracle.tip.adapter.file.outbound.FileIoInteractionSpec"
          SourcePhysicalDirectory="foo1"
          SourceFileName="bar1"
          TargetPhysicalDirectory="C:\JDevOOW\jdev\FileIoOperationApps\MoveHugeFileWithXlate\out"
          TargetFileName="purchase_fixed.txt"
          SourceSchema="address-csv.xsd"
          SourceSchemaRoot ="Root-Element"
          SourceType="native"
          TargetSchema="address-fixedLength.xsd"
          TargetSchemaRoot ="Root-Element"
          TargetType="native"
          Xsl="addr1Toaddr2.xsl"
          Type="MOVE">
      </jca:operation> 7. Edit the outbound header to look as follows
    <types>
        <schema attributeFormDefault="qualified" elementFormDefault="qualified"
                targetNamespace="http://xmlns.oracle.com/pcbpel/adapter/file/"
                xmlns="http://www.w3.org/2001/XMLSchema"
                xmlns:FILEAPP="http://xmlns.oracle.com/pcbpel/adapter/file/">
            <element name="OutboundFileHeaderType">
                <complexType>
                    <sequence>
                        <element name="fileName" type="string"/>
                        <element name="sourceDirectory" type="string"/>
                        <element name="sourceFileName" type="string"/>
                        <element name="targetDirectory" type="string"/>
                        <element name="targetFileName" type="string"/>
                    </sequence>
                </complexType>
            </element>
        </schema>
    </types>   8. the last trick is to have an assign between the inbound header to the outbound header partner link that copies the headers. You only need to copy the sourceDirectory and SourceGileName
    <assign name="Assign_Headers">
      <copy>
        <from variable="inboundHeader" part="inboundHeader"
              query="/ns2:InboundFileHeaderType/ns2:fileName"/>
        <to variable="outboundHeader" part="outboundHeader"
            query="/ns2:OutboundFileHeaderType/ns2:sourceFileName"/>
      </copy>
      <copy>
        <from variable="inboundHeader" part="inboundHeader"
              query="/ns2:InboundFileHeaderType/ns2:directory"/>
        <to variable="outboundHeader" part="outboundHeader"
            query="/ns2:OutboundFileHeaderType/ns2:sourceDirectory"/>
      </copy>
    </assign>you should be good to go. If you just want pass through then you don't need the native format set to opaque, with no XSLT

Input file size limition in File Reader Adapter

Hi,
We have a File Read Activity(using File Reader Adapter) which works on a Polling model. Whenever a input file is found in a designated directory it invokes our BPEL web service. During load testing we found out that if input file size exceeds 7 MB then we get "insufficient heap space" error. We found a reference to this size limitation in http://download.oracle.com/docs/cd/E11036_01/integrate.1013/b28994.pdf which has below lines..
"Files that are 7MB or larger in size cannot be delivered. As an alternative, you can debatch large files (if they have multiple messages), and publish these files in messages of size less than 7 MB. This alternative is applicable only to structured files (comma-delimited or fixed position), which contain more than one message. It is not applicable to binary or XML files."
Our customer will have the data in XML format and the size of the files will be pretty huge(running into 49, 69 MBs). Do we have any workaround here or we are left with no option but to ask the customer to split the files and load it? The later option is currently difficult one for the customer since when split there is a possibility of XML becoming invalid. Any pointers in this issue is appreciated.
Thanks!
Balaji

Hi,
BPEL can not process more than 7 MB size xml structred file. but,debatching will work for xml files also provided if the file has repeated multiple structures (means multiple repeated root elements).

Maximum file size data that can be send to MQ using mq adapter

Dear All,
What is the maximum file size data that can be send to MQ using mq adapter ?
The file can be csv, fixed , xml.
Please let me know if anybody is aware of any limitations
Best Regards
Arc

If you are on 10g then you are looking at a limit of 7MB, although any messages over 1MB will require some tuning.
You can integrate using the native schema, or xml so you can use csv, fixed length, and xml files.

Reg: File size in receiver file adapter

Hi all,
I am doing a proxy-> Flat file scenario. The output file size is nearly 15MB.
Can anyone please tell me whether file adapter in PI 7.1 can write this much big file?
or do i need to split it in integration engine?
Regards
Jagruthi

Hi Jagruthi,
>>The output file size is nearly 15MB.Can anyone please tell me whether file adapter in PI 7.1 can write this much big file?
Yes it can, provided there is less load on the server and the interfaces running are minimal. Also the frequency of this interface should be very less
>>or do i need to split it in integration engine?
If possible try to split records and create file be appending

What is the max file size that a Adapter Engine [J2SE] can handle ?

We are having a scenario where a 4 GB compressed file needs to be sent across without mapping, I'm trying to explore the possible options to tackle this scenario.
Some of the options, we are considering :
- Sending a file from one Adapter Engine [J2SE] to another Adapter Engine [J2SE] bypassing PI. Adapter Logs will be monitored. What is the maximum file size that can be then handled assuming a standard installation ?
- What is the max file size that Adapter Engine [J2SE] can send through PI without mapping?
Any help with the above options or with any other possible solutions to handle extremely large file transfers will be much appreciated.

Hi,
j2se is not a good option here
if you have 4gb then you need a copy solution
a) build an proxy that will just copy the file from sender dest to receiver
b) build an adapter that will do the same as proxy)
this way processing of this message will be controlled with SAP PI/XI
it will be as quick as copy & paste of the 4gb file
I did the a) for one of the flow for 300 mb and it works perfectly

Michal Krawczyk

FTP Adapter File Size Limit

Hi,
Is there a limit on file size for FTP 'put' operation in BPEL/ESB FTP adapter for the file in ASCII format?
For File adapter polling the limit is 7 MB unless Debatching feature is used I think.
Thanks

There used to be but in 10.1.3.4 the restriction has been lifted but there are some restrictions. If you have File / Ftp input and File / Ftp out put you can use the MOVE functionality
http://download.oracle.com/docs/cd/E12524_01/relnotes.1013/e12523/adapters.htm#CHDHJGHG.
If you are using DB adapter this won't work and the 7MB file limit exists, although this is really streatching it. I wouldn't go above 1MB. Oracle Data integrator is a good option for this kind of pattern.
cheers

Soa 10g Ftp adapter file size

Hi,
I am using a ftp adapter to transfer files. I am placing a 9kb file but after the transfer at the destination I find the file transferred but the file size is 2.8kb. Please do suggest me the possible solution and the reason for this issue
Thanks

What 10g version do you have?
Try adding the following property to your outbound ftp wsdl file:
<partnerLinkBinding name="xxxxx">
*<property name="control.read.timeout">10000</property>*
</partnerLinkBinding>
(it's in milliseconds)

How to generate a csv report to determine paper size in a pdf or pdf/a file ?

how to generate a csv report to determine paper size in a pdf or pdf/a file ?

Use the cfpdf tag as follows:
<cfpdf
    action = "getinfo"
    name = "pdf_info"
    source = "C:\temp\testFile.pdf">
My Operating System is Windows. This tag gets information about testFile.pdf, and stores it in a structure. I have given this structure the name pdf_info. This structure has the key you are interested in, namely, pageSizes.
Pdf_info.pageSizes is an array whose indices correspond to the respective page number in the PDF. You can use this to generate Comma-Separated Values (CSV) for each page.

<cfset csv = "">

<cfset csv = "Page,Height,Width" & chr(13)>
<cfloop from="1" to="#arrayLen(pdf_info.pageSizes)#" index="i">
<cfset row_info = i & "," & pdf_info.pageSizes[i]["height"] & "," & pdf_info.pageSizes[i]["width"] & chr(13)>
<cfset csv = csv & row_info>
</cfloop>

<cfoutput>#csv#</cfoutput>


Done!

Regarding your statement: "If you Enter Time Machine (the "Star Wars" interface), from a Finder window with a "size" column, then browse your backups, you should be able to see the sizes easily." - what do you mean by the "Star Wars" interface?
Ah, you are new to Time Machine. Sorry, that's how you view and restore from your backups. Hold your mouse down on the TM icon in your Menubar and select +*Enter Time Machine,+* or click the TM icon in your Dock, or the +*Time Machine+* app in your Applications folder.
If I look at the pull-down menu under Finder, I do not see Enter Time Machine. Am I looking in the wrong place? Obviously, since I couldn't get by the first step, I never got to a "size" column, and to be honest, I don't know that I have ever seen a Finder window with a "size" column.
You can add one, by selecting View > as List, then View > Show View Options in a Finder window's menubar, and select or de-select whatever columns you want.
I'm a little embarrassed by my lack of knowledge, but if I don't acknowledge my shortcomings, I'll never get the question answered. Thanks for taking your time to try to help me.
Don't be. We all started at zero at one time or another.
I'm not sure just what you were looking for in your first post. The size of all your TM backups is just the amount used on your external disk, unless you have other data in the same partition (which isn't a good idea). Because of the way TM works, you can't really determine the size of an individual backup, and it really wouldn't mean much.
Perhaps if you clarified just what you want to know, we can help answer it.
