Sender RFC and JDBC communication channels required to be activated

Hello Guys,
Whenever we have a Oracle restart after the server is shut down for maintainence . The sender JDBC communication channel does not poll and we have to activate the channel again in the Integration Directory to make it work, is there any way to make it work automatically.
Similar is tha case with the sender RFC communication channel.
Allthough the component monitoring shows green button for the JDBC, RFC communication channel.
In case of the JMS channel (sender) the channels are in red.
Thanks for your help.

HI
There is no automatic ways to restart channel that you have to manually start.
You need to stop the channels first before getting oracle server down for maintenance. This will save from errors. Maximum what you can do is to start stop channel using a program externally but that require development.
Start/Stop using RWB
Starting / Stopping of Communication Channel from RWB
Start/Stop without using RWB

Thanks

Error at sender JDBC communication channel

Dear All,
While executing JDBC(MS-Access)-PI-RFC interface, we are getting error in sender JDBC communication channel. The error is as following:
Error during database connection to the database URL 'jdbc:odbc:Driver={Microsoft Access Driver (*.mdb)};DBQ=
sappidev\Datatran\Database.mdb' using the JDBC driver 'jdbc.odbc.JdbcOdbcDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Can not establish connection:: SQLException: [Microsoft][ODBC Driver Manager] Data source name not found and no default driver specified'.
I have checked various posts on forums and as per those no drivers installation is required to access MS-Access database and I am not able to find any post which could solve my problem.
Kindly guide me on what might be the problem and how this can be resolved.
Regards,
NJ

Hi Nishu,
That error ALWAYS means your DSN name is incorrect or can't be accessed for some reason (permission). The ODBC part says that the bridge is working.
But that DSN is 100% wrong or cannot be seen by the user account that the server is running as. Make sure you have a system DSN and not a user one.
You can refer these....

Need to use only one sender and receiver communication channel.

Hello Experts.
I have a scenario where in I have to use only one sender and receiver communication channel to push files from different source directories to different receiver directories.
For Eg;
Sender
D://dir1/file1 --->                  E://dir1/File1
F://dir2/file2 ---->                 G://dir2/file2
H://dir3/file3----->                 I://dir3/file3.
Can this be achieved by using pass through scenario?
Please let me know if the requirement is not clear.
Thanks in advance.
Advit Ramesh

Hi Advit,
I think it is possible. You have to use the Advanced Selection for Source file in the sender channel to define multiple files to be picked up. Also, the Dynamic configuration must also be enabled and used in the mapping so you can manipulate the target directory and target file name based on your source files.
For Polling from multiple directories:

Error in Sender JDBC communication channel

Dear All,
We have an interface in which we are fetching data from SQL database through sender JDBC communication channel.
Last week SQL server was upgraded from 2000 to 2008 and the communication channel has stopped working and is giving the following error:
Database-level error reported by JDBC driver while executing statement 'SELECT * FROM mstemp_tbl WHERE Active='0''. The JDBC driver returned the following error message: 'java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC][SQLServer]The incoming tabular data stream (TDS) remote procedure call (RPC) protocol stream is incorrect. Parameter 1 (""): Data type 0x38 is unknown.'. For details, contact your database server vendor.
Please let me know if any JDBC drivers are to be installed for SQL 2008 or how can we resolve this.
Thanks,
NJ

Hi,
You may need to update your JDBC driver to 1.2 or 2.0. Kindly see supportability matrix on this link (question #2):

XI: Sender JDBC Communication Channel is not getting picked the records

Hi All,
Here I 'm facing an Issue with my sender JDBC communication Channel. Previously it was working fine but It is not Picking the records from the JDBC table.
Communication Channel is in active mode only.
I have checked in RWB communication Channel monitoring there i didn't get any error or success messages but channel is showing healthy status only(Green)
But i had created the new communication channel..with the same parameters which are in the older communication channel.. and sender agreement level also i had changed.. so now new channel is working fine.... I didn't understand what is the problem with previous communication channel.
Thanks

Hi yadav,
do you have TWO CCs polling at the same time via JDBC?
This could be the problem --> a conflict between both CCs.
Switch off ONE CC:

Processing Started in JDBC communication Channel?

Dear Friends,
in JDBC Sender Channel i am facing one issue, i.e the data coming from DB but in PI/PO 7.4 data is not reached and channel is showing Green color and log is showing processing started. But as per my experience may the data is locked in server level. PI 7.0 for this type of issues we are deleted the locks in adapter level in visual admin. but 7.4 version is not having Visual Administrator. Please suggest how to resolve this issue in sap pi 7.4?
Note: Previously it is working fine.
please find the screen shots for your reference.
Regards,
Kiran Polani

Dear Friends,
i seen ur answers, but if it is production that is not possible to take restart ther server, for this visual administrator -->adapter locks i deleted db locks previously in pi 7.0 but i need solution for 7.4.
2) http://hostname:port/nwa/locks as suggested by naveeen, for this type of issue dblocks are not available in this url location.
and i have check this also no use and stoped communication channel and started so many times no use and maintained DIsconnect from Database after processing each message in channel level

Use EOIO on Sender RFC and outbound ABAP proxy calls

In the comm channel of SOAP and FILE there is a simple flag to set for QOS = EOIO
In Plain HTTP adapter a QOS parameter can be supplied.
IDOC uses control record tricks or a Receiver adapter option.
But what about the RFC and XI adapters.
The docu states QOS of EOIO for RFC and XI adapters is possible.
How is set for sender RFC and Sender XI adapters?
regards
Phil

Phil,
I was discussing with Michal about this.
I suppose it is not fully EOIO, because you don't send directly from the outbound queue to the inbound queue. The AE service may not have a specific queue for that message, until the queue is associated in adapter module. Maybe (just maybe), if you get unexpected extra processing in the initial AE reception of the message (and hence, before the queue is set, in adapter module), you may have some inconsistencies with the processing order in sender system.
But again, that is just a speculation.
I'm not sure what is the behavior it'll have.
And even if what I speculated is right, it is a really short amount of time.
But again, EOIO would not be 100% guaranteed (maybe 99% hehe).
But sometimes (most of the times) that is not enough.
Regards,
Henrique.

Reg jdbc communication channell proccessing

I have scenario i.e JDBC to RFC
but i need small calrification like is it possible to trigger the jdbc sender communication channel automatically whne the file tirggerd from the orcle Database
like without giving the any polling intervals CC should poll when the file triggerd.
i am not going to use that file its just a flag to start the communication channel
can we achive this through OS commands ???
thanks in advance....

Yes you can write script and control the channels externally like give start or stop command at your specified requirement time.
Please see this link
Control Communication Channels Externally without using RWB
Also you can use wget or curl command in the script followed by http url string.
Example:
wget http(s)://host:port/AdapterFramework/ChannelAdminServlet?party=party&service=service&channel=channel&action=start

Problem with Sender File Content Conversion Communication Channel

Hi All,
I am using XI 3.0--SP 16.
I have configured a Sender communication channel with File Content Converison which takes up a Fixed length text file and converts to XML.
My scenario is that I have some 'n' files, out of which one file has error in content conversion.
In a normal scenario I would expect other files to get processed, but they are not.
I can correct the error or even discard the error file. But I am unable to understand why XI is not processing the rest of the good files.
Thanks in advance.
Regards.,
Sudharshan

Hi,
@Renjith
The QOS is EO, thats why I am wondering why it is not picking the rest of the good ones

Stop and Start Communication Channels

Hi All,
I am finding some peculiar entries in my application log which has made my scenario go awry.
I have an AS2 to Proxy scenario. I am receiving the AS2 message successfully and i have to send a synchronous signed MDN back to the sender. I have done the necessary configurations for this and all certificates are loaded and verified.
The strange part is, once i receive the AS2 message and convert it to XML using content conversion, the communication channel is stopped and again restarted. This messages i could find in application log Log entries. This makes the MDN Asynchronous as the existing HTTPS connection with AS2 sender is lost and so the MDN is not delivered as ASYNC MDN method is not set up.
I need to know what are the system processes that can start and stop a communication channel. I am sure i have not set up any availability time planning for these comm channels and also, they are scheduled manually!
Thanks,
Rashmi.

Hi Debashish,
I am using Advantco AS2 Adapter, and they say it is one of the system processes and not anything with their AS2 Adapter.
Thats why this question. Are there any system processes that can start/stop a communication channel? Atleast I have not come across anything like that.
Thanks for your reply,
Rashmi.

Custom Adaptor for JDBC Communication Channel

Hi Guys,
My apologies if this has been asked before, but I did a few searches and could not find anything.
I'm trying to write an adaptor that will use/ access the information passed into a JDBC Receiver communication channel prior to the normal adaptor being called.
Iu2019ve written a module that gets as much information from the ModuleContext and the ModuleData as possible, but I canu2019t find where the information on the database connection is being passed.
Is there any way of accessing the Database Connection information in a custom adaptor module?
Kind regards,
John

Hi 'PI Expert'
Thanks for your reply. I'm not sure we can use that as we're running PI7.0, but just in case:
I can't find too much information suggesting that it's possible to call the Directory API from within an adaptor module allowing the information to be read, and hopefully modified, when the communication channel is used.
Is it possible to call the Directory API from within a custom adaptor module?
Kind regards,
John

Error in Receiver JDBC communication channel

Hi friends,
I am getting an error in communication channel while inserting xml data into ORACLE database. Error is like
"Message processing failed. Cause: com.sap.aii.af.ra.ms.api.RecoverableException: Error processing request in sax parser: Error when executing statement for table/stored proc. 'SUB_ORDER_HEADER' (structure 'STATEMENT_SUB_ORDER_HEADER'): java.sql.SQLException: ORA-00936: missing expression ".
In the above error 'SUB_ORDER_HEADER' is table and 'STATEMENT_SUB_ORDER_HEADER' is a statement tag of XML SQL.
Please help me to solve the issue.

Hi,
Since oracle database has all fields in Caps, and also it is case sensitive. So check whether you have the database table name and the field name specified in the datatype are concurrent with the fields and the table name in oracle table.
