File Adapter vs BPEL interaction issue on high availability environment

Hi all,
i would really appreciate your help on a matter i'm facing about a composite (SCA) deployed on a clustered environment configured for high availability. To help you better understand the issue i briefly describe what my composite does. Composite's instances are started by means of an Inbound File Adapter which periodically polls a directory in order to check if any file with a well defined naming convention is available. The adapter is not meant to read the file content but only its properties. Furthermore, the adapter automatically makes a backup copy of the file and doesn't delete the file. Properties read by the adapter are provided to a BPEL process which obtains them using the various "jca.file.xyz" properties (configurable in any BPEL receive activity) and stores them in some of its process variables. How the BPEL process uses these properties is irrilevant to the issue i'd like to pose to your attention.
The just described interaction between the File Adapter and the BPEL process has always worked in other non-HA environments. The problem i'm facing is that this interaction stops to work when i deploy the composite in a clustered environment configured for high availability: the File Adapter succeeds to read the file but no BPEL process instance gets started and the composite instance gets stuck (that is, it keeps always running until you don't manually abort it!).
Interesting to say, if I put a Mediator between the File Adapter and the BPEL, the Mediator instance gets started, that is the file's properties read by the adapter are passed to the mediator, but then the composite gets stuck again 'cos even the mediator doesn't seem to be able to initiate the BPEL process instance.
I think the problem lies in the way i configured either the SOA infrastructure for HA or the File Adapter or BPEL process in my composite. To configure the adapter, i followed the instructions given here:
http://docs.oracle.com/cd/E14571_01/integration.1111/e10231/adptr_file.htm#BABCBIAH
but maybe i missed something. Instead, i didn't find anything about BPEL configuration for HA with SOA Suite 11g (all the material i found refers to SOA Suite 10g).
I've also read in some posts that for using the db as a coordinator between the file adapters deployed on the different nodes of the cluster, the db must be a RAC! Is that true or is possible to use even another type of oracle db?
Please, let me know if someone of you has already encountered (and solved :)) a problem like this!
Thanks in advance,
Bye!

Hi,
thanks for your prompt reply. Anyway, i had already read through out that documentation and tried all settings suggested in it without any luck! I'm thinking the problem could be related to the Oracle DB used in the clustered environment, which is not RAC while all documentation i read about high availability configuration always refers to a RAC db. Anyone knows if a RAC Oracle DB is strictly needed for file adapter configuration in HA cluster?
Thanks, bye!

How to use File Adapter in BPEL

Hi,
How to use File Adapter in BPEL. I am using Oracle SOA 10g. Any sample or best example in blog or elsewhere ?

Hi,
Please check the below links for samples on how to use file adapter in BPEL (in 10g/11g usage is same) and let me know any further queries.

Reading file using File Adapter in BPEL

Hi,
I am using JDeveloper 11g.
I am trying to Read XML file and write content to Text file.
I created XML Schema, XML file.
I created Asynchronous BPEL process (Auto Generated)
I took one File adapter which will have Read operation and one more File Adapter which will have Write Operation.
Then, added one Receive activity that will be connecting to partner link - Read.
and one Invoke activity which is linked to Write Partner link .
I am able to Deploy the process..
While testing 1st receive (Auto generated) will work but Receive for Read is not getting started.
I am getting " Waiting for "Read" from "ReadFile". Asynchronous callback.Waiting for "Read" from "ReadFile". Asynchronous callback "
How to read file in BPEL process. ?
Thanks

So,You have two receive activity(One for soap client and one for Read activity) and two invoke(1 for write file and 1 for reply to client).
I think the 1st receive activity for soap client not required as you want to initiate the process while read the file.You can delete the default soap client and corresponding receive activity and check the create instance chekbox in the 2nd receive activity linked with read partnerlink.
There is some issue with 2nd receive activity in bpel ..
BPEL 11g -- Issue with second Receive activity

Two Files merging using File adapter in Bpel 2.0

Hi All,
I have two different files (File 1 and 2) of same format(Two columns each) , now i want to merge these two files using their data and form a consolidated file (File 3 with four columns).
Please advise on how to make it possible using file adapter.
Example:
File 1 Format: A1 and A2 - are two columns of number and sring type
File 2 Format : B1 and B2 - are two columns of number and string type
Consolidated File 3 Format : A1 B1 A2 B2 - forming a single row if A1=B1 and also populating A2 and B2.
Thanks
Karthick.

Hi Karthick,
I would say read both files completely. Then create a transform and select both messages as an input creating one output. With XSLT it should not be too hard to combine the two inputs. You could loop on one file and then select each row from the other file. That output can be written to file.
I don't know what triggers the process, but you could either let bpel be triggered by the polling on one file and read the other synchronously. Or read both files synchronously.

Martien

File adapter: End of line issue in unix receiver

Hi all,
We are sending flat files using File Adapter (FTP) with the File content conversion functionality and we can see the file right in our windows system, but when it arrives to the Unix receiver, they give us an error regarding the End of line.
It has a ^M character in every line so it cannot be processed.
Does anyone know how to skip this end of line character in our file keeping the same format?
Thanks in advance.

Hi Daniel,
you can try to use this adapter module:

Polling using File Adapter in BPEL

My requirement is to constantly poll a directory location using file adapter for a particular filename. If the file is found then pick the file else continue polling.
Any thoughts on the approach is appreciated.

Refer the below, File adapter is capable of doing that.
http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/adptr_file.htm#CIAHDAEB
for File Polling refer *4.3.1.4 File Polling* section

This schema works fine and data is produced as expected when I am using "chars" as the stream option.However I can't use "chars" as the stream option and need "bytes" as the stream option. However when mentinong "bytes" option the following exception is generated:
Charset "MS932" not supported.
Check the error stack and fix the cause of the error. Contact oracle support if error is not fixable.

Please let me know can I at all read a file in byte format with File adapter using a desired encoding style?This is littile urgent.
Thanks

Hi James,
Yeah I tried that too and it gave the same error. And I need to encode with MS932 only since the data will contain Japanese characters and this encoding is identified both by windows and non-windows OS.
Please can you advice what can I do since the requirement is urgent.
Thanks

JDBC adapter connected to a DB in high availability!

Hi folks,
I have finished my scenario File -> XI -> JDBC and now Im preparing to transport it to QAS. I found that Data Base of QAS is in two cluster nodes. I have two hostnames to fill the parameter <b><IP address></b> and I dont know which hostname I should use! Is it supposed use both? or I need another one virtual?
Connection: <b>jdbc:oracle:thin:@<IP address>:<listener port>:<instance name (database name)></b>
Thanks in advance,
Ricardo.

I don't know this mechanism of high availability with 2 IP, but if you really have 2 hostname you should think to a method to switch from a node to the other in easy way, deactivating one and activating the other (for instance with the <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/45/0c86aab4d14dece10000000a11466f/frameset.htm">Controlling a Communication Channel Externally</a>)
I suggest you to verify how it will be in production instance: real cluster ? switch over ? virtual IP ?

Sandro

SAP Web Dispatcher in a high availability environment

Hello, guys
We are working in a CRM 7.0 implementation Project. Our system landscape is the following:
   - Two hosts (host1 & host2) on MSCS cluster (Windows 2008) with SQL Server and ASCS in high availability. Additional, this MSCS cluster has a instance of SAP Web Dispatcher.
   - In these two host weu2019ve installed a CI & DI instance, outside of high availability scope
   - Two additional hosts (host3 & host4) with one dialog instance in every host
We have severe problems with communication between SAP Web Dispatcher and ICM components. Our configuration schema is the next:
   - ASCS (MSCS_virtual_hostname):
ms/server_port_0 = PROT=HTTP,PORT=8141
SAPLOCALHOSTFULL = <MSCS_virtual_hostname>.<domain>
   - IC (host1)
icm/server_port_0 = PROT=HTTP,PORT=8040,TIMEOUT=90,PROCTIMEOUT=600

SAPLOCALHOST = <MSCS_virtual_hostname>
ms/http_port = 8141
icm/server_port_0 = PROT=HTTP, PORT=8042,TIMEOUT=30,PROCTIMEOUT=600
wdisp/add_xforwardedfor_header = TRUE
In SAP Web Dispatcher log weu2019ve found the following error messages:
Fri Jan 28 15:45:22 2011

*** ERROR => Connection request to host: , service: 8044 failed (NIECONN_REFUSED)
SAP Web Dispather is trying to connect to connect with dialog instances through , which itu2019s incorrect (ports 8044, 8045 & 8046 are opened in dialog instances, not in virtual instance). I think it should try with real hostnames (host1, host2, host3 & host4).

Sender File adapter complex structure FCC issue - flat structure RFC-stuck

Hi,
Please help.
I have a the below file structres-
Option 1-
H,100890,P100,A02,S101,AUD#
I,P,NULL,TH,Test PO TH,1,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
I,P,NULL,TH,Test PO TH1 2,2,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
H,100899,P100,A02,S101,GBP#
I,P,NULL,AS,Test PO AS1,1,EA,100,10160000,A002,0001,720090,E.1.4.2,,,,VT#
I,P,NULL,AS,Test PO AS12,2,EA,100,10160000,A002,0001,720090,E.1.4.2,,,,VT#
I need to map this into a Z RFC which is expecting all the data in one row - of course multiple rows
Option 2-
Same structure as above but all in same row-
H,100890,P100,A02,S101,AUD,P,NULL,TH,Test PO TH,1,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
I,100890,P100,A02,S101,AUD,P,NULL,TH,Test PO TH,1,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
I,100890,P100,A02,S101,AUD,P,NULL,TH,Test PO TH1 2,2,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
H,100899,P100,A02,S101,GBP,P,NULL,AS,Test PO AS1,1,EA,100,10160000,A002,0001,720090,E.1.4.2,,,,VT#
I,100899,P100,A02,S101,GBP,P,NULL,AS,Test PO AS1,1,EA,100,10160000,A002,0001,720090,E.1.4.2,,,,VT#
I,100899,P100,A02,S101,GBP,P,NULL,AS,Test PO AS12,2,EA,100,10160000,A002,0001,720090,E.1.4.2,,,,VT
This also needs to be mapped into a Z RFC which is expecting all the data in one row - of course multiple rows
I am getting issues in getting the file data across to Receiver adapter.
I have tried various combinations but the message is failing in SXMB_MONI.
How do i do it as i need to get the finalised option for incoming file structure?
Option 1 is being stressed but how do i map it if i cannot get the receiver structure in RFC.
Please help as I am stuck now.
Regards,
Archana

Hi,
The problem is basically in message mapping from file to RFC external message.
The option 2 is working now and I get correct converted file strcuture after FCC and into RFC and also a correct RFC payload.
However, business is stressing that can send the file in the format as given in Option 1 where u have different structure - Header and Items. This is not coming out correct in RFC payload as the header has 5 fields as compared to more in item but the header and item are still being mapped to the flat RFC structure and this is creating a mismatch. The item line is missing the 5 fields from Header.
How do i do the FCC in this situation to get the correct structure in RFC?
This means that in RFC payload, the first line should be the one as below-
H,100890,P100,A02,S101,AUD#
The 2 records after this as received in RFC internal table should be as 2 given below-
I,P,NULL,TH,Test PO TH,1,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
I,P,NULL,TH,Test PO TH1 2,2,EA,100,10160000,A002,0001,720090,E.1.4.3,,,,VT#
However, the 2 structures contain variable field columns.
Please help.

NW2004s Installation fails in High Availability Environment

We are installing our Production Server
SAP Netweaver 2004s with High Availablility.
AS per the inst guide, we installed the Oracle 10G in Local Disk of both the nodes.
Then Installed the OFS and the SCS Instance successfully.
Then we created the Oracle Fail Safe Group.
After this when we try to install the Database Instance, During the Prerequisites Check, we are getting the message as the
"Oracle Software is not installed. Install Oracle First"
But we have the Oracle installed in the Server into local disk.
Any Ideas?
Thanks & Regards
Sumanth

Hi Benny,
Thanks for the info. We recieved a reply in OSS stating that NW2004s in HA is note tested.
It will only work with NW2004s SR1.
Now we are plannign to go with Distributed System installation without HA because we will not get the NW2004s SR1 DVD.
Where can we get the info about how to Convert the System Landscape from the Distributed System to HA System. Is this possible as part of the migration or as a seperate installation.
Can you please help me in your views on Converting from Distributed Environment to HA Environment.
Thanks & Regards

How to find EOF in BPEL File adapter

Hi All,
I am using file adapter in BPEL(SOA 11G) to read a csv file. The CSV file is very large so we have are processing the files in batched of 20000 records.I am inserting the records form CSV file to a staging table and after that I am invoking a concurrent Program for further processing.This is working fine and BPEL is initiating no of instances based on the file size.
The issue here is, I want to submit the concurrent program only once when all the records are stored in staging table, I mean to say the BPEL Process should process the file in batches and then insert them in to the staging table. Once all the records from the file are stored in the table, then only the Concurrent Program should get submitted.
I am using DB Adapter for invoking a PL/SQL API and from there we are submitting concurrent Program.
Please help me on this to solve this.
Thanks!

It is possible to register a Java Listener class, which can/will be invoked, when a last batch in the file, is read. Code for invoking the concurrent Program can be written in side this class.
Refer to following document on how to register the Java Listener class
http://docs.oracle.com/cd/E23943_01/integration.1111/e10231/adptr_file.htm#CACJBIGD
Moreover, as an alternate to the above approach, chunk read interaction specs can be implemented along with the Sync File Read for your scenario( However,This will be a whole re-write, considering your current approach. Good News is, there is full-fledged example readily available for this in oracle docs).
Here is the link if you would like to implement the Chunk Read.

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:

File Adapter to EJB in BPEL

Hi,
I have one XML file that i am reading using File Adapter in BPEL process. after reading i want to pass those values to EJB Adapter.
I used Trasform to mapp output variables of File Adapter to Input parameter of EJB service.
But the Invoke process is not happening.
How to Pass values from File Adapter to EJB ?
Thanks

Hi Sonia
It is not possible to achieve this using debatching. In fact, the use of the Debatching technique is appropriate when your requirement is exactly the opposed: When you need to run instances simultaneously.
If you need to process each record sequentially, you should consider using just one instace (not using debatching and let the process reads the entire file), using a while and considering your XML as an array, processing each record as a single unit.
If the CSV file is too big, you should consider using a process A that breaks the file into smaller files and copy sequentially the small pieces to a directory where process B is reading the entire file.
