Performance JDBC Receiver

Hi experts,
I have 02 environments PI 7.0 SP 13 and did the same to Deploy JDBC driver.
I've created a RFC to JDBC Synchronous Interface, and I am troubled performance in an environment, the response time of the database is 00:00:03 and 00:01:00 for the same Interface.
The other adapters have no difference in performance.
Why?

Yes, the only difference is the HW.
But tests done at one of ambient, and processing time for INSERT with 1 record is almost 01 minutes.
See Log of Message Monitoring:

Broken pipe error in Sync Send JDBC Receiver: Extremely Serious issue

Hi forum,
I have a serious error in a JDBC->XI--> JDBC scenario,
Step1: I use a sender JDBC channel to select some distinct values from a table say X, and update the same rows,
Query SQL Statement: select distinct Branch from dbo.X where status = 0
Update SQL statement: update dbo.X set Status = 2 where Status = 0
Step 2: enter BPM
Step 3: enter a loop
Step 4:make a synchronous call to the same table X, to fetch some records,
SQL query: select * from X where status = 0 and Branch = i; Update X set status = 9 where Branch = i
Step 5: close loop, this loop iterates for 5 or 6 times depending on i, which is no. of branches selected by the sender JDBC channel
so all the calls are to the same table, same databsse(SQL Server)
the problem is when this sync calls happens in the loop, it some times gives following error, which i se in RWB:
<b>Error Unable to execute statement for table or stored procedure. 'X' (Structure 'STATEMENT_X') due to com.microsoft.sqlserver.jdbc.SQLServerException: An exception occurred during the DBComms.transmit operation. Exception:Broken pipe (errno:32). Context:(2217)</b>
i have no way to trace the cause of the error, the database is perfect and the error logs in the SQL server shows no trace of any error,
Note: It works sometimes
i dont know whom to approach, pls help
the issue is very very serious as its in production system,

Hi Sudeep,
SAP Note 846079 - XI 3.0 JDBC Receiver: # of Retries on SQL Error w/o Effect
Please check the following SAP note also - 831162
Some info which i found there and can be relevant in to your scenario.....
Q: I am using a JDBC Receiver Adapter in conjunction with the Lotus Domino Driver for JDBC perform an INSERT or UPDATE operation on a database. When sending a message to the receiver, the Adapter Monitoring shows the following error message:
"java.sql.SQLException: [Lotus][Domino Driver for JDBC]Invalid cursor state"
Is there a fix for this issue?
A: To work around this JDBC driver problem, activate the Advanced Mode for the respective JDBC Receiver channel and configure the setting "Number of Retries of Database Transaction on SQL Error" to a value > 0. Additionally, make sure that the setting "Database Auto-Commit Enabled" is also active as the Lotus Domino Driver for JDBC does not support transactions.
Apply note 846079 before configuring this scenario.
Q: The TCP/IP connection to my database host is running over an unreliable network connection, i.e. the connection is sometimes interrupted. Consequently, I sporadically receive an SQLException regarding a closed connection in the system trace or audit log or the connection as well as the JDBC Adapter channel are hanging.
How can I work around this connectivity issue?
A: Enable the "Advanced Mode" for the respective JDBC Adapter channel and select the option "Disconnect from Database After Processing each Message".
Note that this might put additional load on your DBMS due to the creation of a new database connection for each message.
I dont have access to a database right now, so i am not able to check this.
Also check the JDBC driver compatability as mentioned in the above note.

How many messsages can we insert using JDBC receiver adapter in to DB

Hi Friends,
We are having 30 JDBC receiver interfaces in my current implementation project; load of JDBC receiver interfaces was 50 k messages per day and Performing only INSERT operation on data base.
We have created individual communication channel for every JDBC receiver interface and max concurrency value set in CC was 5.
Now we are testing all interfaces in quality with all possible cases, but we found that JDBC receiver adapter unable to process 50 k messages per day, we are on PI 7.1 EHP1 SP7.
Please share your experiences with JDBC adapter receiver like per day how many messages we can transfer.
Thanks a Ton,
Raj

Hi raj,
I have seen some interfaces that deal with upload of 5000 rows at a rime.. I don't there will be a restriction in the no of messages that can be transferred using the JDBC adapter as such unless until the requirement is so para-normal and in your case it is not

How many JDBC receiver CC?

Hi all,
I am in doubt how many JDBC receiver CC I need to configure. I have many different inbound interfaces on database side (Oracle ). At first I have thought that I would need one JDBC receiver per interface, but now it seems that one CC could be enough, since there is no difference in the CC parameters. Is it correct to use one JDBC receiver for many interfaces ?
Please advice.
Thanks, Janos

Hi,
Technically it is possible to have single CC for one DB & Port however its good to have multiple channels as it will improve performance.
If you have 10 interfaces, 1 Receiver Channel with concurrency 1 then these 10 messages will be delivered to target DB in sequencial manner.
However by increasing concurrency you can do parallel processing.
If you have 10 interfaces with 10 receiver channel, all these 10 messages will be procesed parallel inspite of keeping concurrency 1.
I suggest if you have multiple messages and many interfaces, you go for different CC. If Load and no of interfaces is less, then one CC can also be sufficient.
Hope this helps.

Error handling at JDBC Receiver

Hi,
I am currently working on PI 7.31. This is regarding proxy to JDBC scenario using insert statement in the JDBC receiver. I would like to know is there any feature in JDBC receiver which allows the process to continue even after any data error in the insert statement by skipping the error records and finally collecting all error records and sending through alert configuration to the administrator. Currently process stops whenever any error happens in insert statement at JDBC receiver.
Regards,
Rama.

Hello,
I would suggest you to go with SP.
By default, PI will handle the transaction and in case of any errors it will rollback the entire statement. So u can allow SP to handle the transactions by asking ur DB team to create a SP with a try/catch statement and in case of any errors while performing DML operations catch those exceptions and log those erroneous records in some exception log table and continue the SQL process.
Eventually, either using SQL mailer or some windows services u can send a consolidated mail to the stakeholders. Just check with ur DB team since these are very normal stuff so i am quite sure ur DB admin would certainly help u on the same.
Thanks

JDBC Receiver : Handling NULL return from SELECT query

Hi All,
I have a Proxy <-> XI <-> JDBC synchronous scenario. I have designed my message mapping to perform a select query using JDBC receiver adapter. The request message mapping structure at the JDBC end is as follows.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Matmvmt_Jdbc_Request xmlns:ns0="http://esag.com/xi/bat/MatMovementRead">
   <StatementSelect>
      <Tablename action="SELECT">
         <Table>MM_DATA</Table>
         <access>
            <SEQNO/>
            <MATERIAL/>
            <UOM/>
            <SOLDQTY/>
            <SAPUPD/>
         </access>
         <key compareOperation="EQ">
            <SAPUPD>N</SAPUPD>
         </key>
      </Tablename>
   </StatementSelect>
</ns0:MT_Matmvmt_Jdbc_Request>
The scenario works fine when there are records matching the select condition, but when there are no records matching the select condition (i.e. if there are no record with value SAPUPD = 'N' ) then my response message is returning the empty message strucuture as given below.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Matmvmt_Jdbc_Request_response xmlns:ns0="http://esag.com/xi/bat/MatMovementRead">
   <StatementSelect_response/>
</ns0:MT_Matmvmt_Jdbc_Request_response>
My requirement is that if there are no records matching the select condition then my response message should look like below.
<?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Matmvmt_Jdbc_Request_response xmlns:ns0="http://esag.com/xi/bat/MatMovementRead">
   <StatementSelect_response>
      <row>
         <SEQNO/>
         <MATERIAL/>
         <UOM/>
         <SOLDQTY/>
         <SAPUPD/>
      </row>
   </StatementSelect_response>
</ns0:MT_Matmvmt_Jdbc_Request_response>
Note : I have made the occurence of the request and response message elements as miniccurs = 0 and maxoccurs = 1.
Any inputs in this regard will be highly appreciated.
Regards,
Sandeep

Hi Sandeep,
you can not expect structure like <?xml version="1.0" encoding="UTF-8"?>
<ns0:MT_Matmvmt_Jdbc_Request_response xmlns:ns0="http://esag.com/xi/bat/MatMovementRead">
   <StatementSelect_response>
      <row>
         <SEQNO/>
         <MATERIAL/>
         <UOM/>
         <SOLDQTY/>
         <SAPUPD/>
      </row>
   </StatementSelect_response>
</ns0:MT_Matmvmt_Jdbc_Request_response>
   if there is no data in table. The response which you are geting is standard format which you can not change. Instead you map this response with mapwithdefault node function while mapping to target to make the response mapping success, even though there is no data in response message.
thanks,
madhu

JDBC Receiver - Muliple parallel connections?

Hi ,
Does the Receiver JDBC adapter support multiple parallel connections to the database. Can the calls be made in parallel. If yes then where is this parameter (maximum connections) set?.
I was testing an RFC to JDBC sync scenario... My call from the RFC were in parallel (after I increased the max connections in the sender RFC).. but I did not find a similar parameter in JDBC....the db team reported that only one connection was created from Xi...

Have a look at the possible performance enhancement options at JDBC receiver:
1. You may increase the thread count for JDBC related queues. This has to be done in accordance with SAP Note 1084161.
2. There is parameter in JDBC communication channel called Maximum Concurrency. It signifies that one communication channel can make how many connections to database. This is 1 by default and could be increased to some values like 3-4.
3. In the Visual Admin/ NWA, there is a parameter called as queueParallelism.maxReceivers which defines the number of parallel worker threads for one receiver channel instance. This should be done following SAP Note 1136790. This can be done along with the first point.

Delay in JDBC Receive Adapter

Hi Everyone.
I have an asynchronous scenario, RFC -> PI -> JDBC (Oracle DB)... This does an UPDATE in each message... When try to process 400 message the time of execution in the DB takes 2 minutes. For the client, this time is too long, but I've done everything and the time does not improve.
This is the message:
<?xml version="1.0" encoding="UTF-8"?>
<ns1:SQLString xmlns:ns1="urn:envioinventario:sap:seus">

</Inventario>
</Statement>
</ns1:SQLString>
And this is the configuration of the cc:
Please, I need help, I don't know what else to do.

Calling stored procedure multiple times in the JDBC receiver

Hi,
I am calling the stored procedure(SP) to update a DB table in the JDBC receiver.
SP has 10 input parameters, and SP can receive one value for each parameter at a time.
In my case, i will have multiple rows to insert using SP.i.e multiple values for each parameter.
Its working correctly for a single value for each parameter, but when i have multiple values i want to call the SP multiples times.
Is this possible and how?
Thanks,
Varghese.

Varghese,
I think you can have multiple statements in the JDBC Adapter's XML, as in http://help.sap.com/saphelp_nw04/helpdata/en/2e/96fd3f2d14e869e10000000a155106/content.htm.
Here the StatementName1 node can be inserted into your JDBC XML as often as you want.
Kind regards,
Koen

Not able to insert the data in JDBC receiver

hi Team,
Please help me i am working on IDOC - JDBC interface i am not able to insert data into the table.
error says that table doesn't exists, but if i check in the database the table exists..
below is the error getting triggered.
could not execute statement for table/stored proc."A_PORDER_REG"(structure " STATEMENT") due to
java.sql.SQLException: ORA - 00942 table does not exist
Thanks & Regards,
Vishnu vardhan.

Might be u have given table name is diffarent, table name must be match in table field of jdbc receiver structure and table name of data base tables.both places u must give the same table names . this is one reason another one u might be given jdbc structure is wrong. u must specify jdbc structure like this.
   STATEMENT
   TEST
    action(attribute) (action u specify as INSERT)
   TABLE( here u give the table name )
access ( below u write the fields)
and one more is u check the receiver communication channel in that u check properly u have given jdbc drivers, connections , user name and pass word.
check all those things definatly u wil find the error.

JDBC Receiver does not convert empty string to NULL

Hello experts,
I am facing a problem with an INSERT statement to ORACLE DB where some of the fields are empty, for example:
- <STATEMENT_VLP_CONT_DETAILS>
- <TABLE_VLP_CONT_DETAILS ACTION="INSERT">
<TABLE>VLP_CONT_DETAILS</TABLE>
- <ACCESS>
<VLP_HDR_ID>43</VLP_HDR_ID>
<VLP_CONT_LINE_ID>1</VLP_CONT_LINE_ID>
<QUANTITY>1</QUANTITY>
<OWNER>CBHU</OWNER>
<SERIAL_NO>3372739</SERIAL_NO>
<CONT_ISO_CODE>2300</CONT_ISO_CODE>
<WEIGHT>6.44</WEIGHT>
<POL>ILASH</POL>
<POD>FRFOS</POD>
<FD>FRFOS</FD>
<OPER_CODE>COS</OPER_CODE>
<CUR_STOW_LOC>150102</CUR_STOW_LOC>
<PRV_STOW_LOC />
<HAZARDOUS>N</HAZARDOUS>
In the JDBC Receiver comm channel I selected: Interpretation of Empty String Values = NULL Value.
It seems the empty strings are not converted to NULL values as can be seen in the reflected SQL statement in RWB:
INSERT INTO VLP_CONT_DETAILS (VLP_HDR_ID, VLP_CONT_LINE_ID, QUANTITY, OWNER, SERIAL_NO, CONT_ISO_CODE, WEIGHT, POL, POD, FD, OPER_CODE, CUR_STOW_LOC, PRV_STOW_LOC, HAZARDOUS, EMPTY, REFER, OOG, HAZARD_IMDG, TEMP_SET, TEMP_MIN, TEMP_MAX, FRONT_OVL, REAR_OVL, RIGHT_OVW, LEFT_OVW, OVERHEIGHT, COMMODITY, BOOKING_REF, ALLOTMENT, YARD_LOC, LD_SEQ_CRANEID, LD_SEQ_NUMBER, LD_STATUS, STACKABLE, OPT_PORT_CODE1, OPT_PORT_CODE2, OPT_PORT_CODE3) VALUES (44, 1, 1, CBHU, 3372739 , 2300, 6.44, ILASH, FRFOS, FRFOS, COS, 150102, , N, N, N, N, , , , , , , , , , , , , , , 0, 64, N, , , )
So, I am getting the following error:
Could not execute statement for table/stored proc. "VLP_CONT_DETAILS" (structure "STATEMENT_VLP_CONT_DETAILS") due to java.sql.SQLException: ORA-00936: missing expression
Help would be appreciated.

Hi Effi,
There is a mismatch in the field and thier value.
Here field id 37
VLP_HDR_ID, VLP_CONT_LINE_ID, QUANTITY, OWNER, SERIAL_NO, CONT_ISO_CODE, WEIGHT, POL, POD, FD, OPER_CODE, CUR_STOW_LOC, PRV_STOW_LOC, HAZARDOUS, EMPTY, REFER, OOG, HAZARD_IMDG, TEMP_SET, TEMP_MIN, TEMP_MAX, FRONT_OVL, REAR_OVL, RIGHT_OVW, LEFT_OVW, OVERHEIGHT, COMMODITY, BOOKING_REF, ALLOTMENT, YARD_LOC, LD_SEQ_CRANEID, LD_SEQ_NUMBER, LD_STATUS, STACKABLE, OPT_PORT_CODE1, OPT_PORT_CODE2, OPT_PORT_CODE3
And value is 35
44, 1, 1, CBHU, 3372739 , 2300, 6.44, ILASH, FRFOS, FRFOS, COS, 150102, , N, N, N, N, , , , , , , , , , , , , , , 0, 64, N, , ,
Give empty values for nuil fields so that they can be made NULL by jdbc adapter

Rahul,
> In this case i believe the interface has to be synch.
> So what will the response message type be like..
Not necessary. UPDATE can be asynch as well.
Can you turn the trace on like pointed by Michal and then you can see the Query in the Audit Log of the adapter montioring. Try to execute the same query from your DB Client like TOAD and see what is the Syntax error you are getiing.!
The problem looks like some field has some dataype / column name mismatch.

How to use Native SQL statement in JDBC receiver interface

Dear All,
Can any one please help us in using Native SQL statement in a JDBC receiver channel. The reason why I need to use Native SQL statement instead of standard XML structure is that I need to execute a dynamic SQL query in third party database system lke:-
Select Field1 Field2 from TABLE Where Field3 like "%Name'
I expect the the response in the form of XML file which I can pick up using synchornous interface as mentioned on help.sap.com:-
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
http://help.sap.com/saphelp_nw04/helpdata/en/64/ce4e886334ec4ea7c2712e11cc567c/frameset.htm
The value for %Name can change dynamically according to the transaction and hence cannot be inluded as a KEY element in standard XLM structure,
Hence I need to know:-
1. What message mapping I should use in case if I have to use Native SQL statement.
2.What operation mapping I should use in case if I have to use Native SQL statement.
If guess correclty I may have to use Java mapping to do the above activities. Hence I want to know
3 .How do to go about it to do the Java mapping.
Thanks

You can use a stored procedure, and call it from jdbc receiver adapter.
I also solve this issue, with a DBLookup in message mapping. You can refer to my blog, and this usefull 3d:

Using TEST mode in sender file channel to trigger jdbc receiver channel

Hi
In order to call a jdbc receiver channel every 15 minutes I intended to use a file sender channel as a trigger where I set the Processing Mode to TEST. However, I would like to make multiple simultaneous different calls to the jdbc receiver channel, so I have multiple files in the folder, where the file sender channel is listening. Quality of Service in the file sender channel is set to Best Effort as the call is syncroneous.
However, because the messages in the folder are not deleted, only the first message is being processed no matter whether I choose Processing Sequence "By Date" or "By Name".
I would like to avoid having to create 15 folders containing one message each, so is there another way of doing it?
By the way, I redirect the response from the jdbc receiver channel to a different folder, but I think this is irrelevant in this case.
I use PI 7.11
/Mikael

Thanks for your answer, but I would like to avoid using Availability planning.
Right now I am thinking about using "Advanced selection for source file" and then just specify 14 different folders here each containing one trigger message, but it seems that only the oldest message (if I choose Processing Sequence = Date) or the first message alfabetically (if I choose Processing Sequence = Name) is being processed across the many folders which I think is very weird!
