Agent operating inside transaction

Hi,
(Using CMSDK 9.0.3) Is it possible to have an agent react to an event (for example an upload of a file taking place through the FTP Server) inside the FTP transaction, i.e. once the FTP operation is completed, the agent's work is done too - and the user will immediately see the results of what the agent has done.
For example: an agent that relocates a files to a folder based on some characteristics (extension, filesize, contents, time of day) after it has been uploaded to a staging folder. Immediately after the upload is complete, the file should show up in the new destination folder.
Can this be done, or do agents operate a-synchroneously with regard to the events that they have registered for and is the best you can do is hope for an agent to react very quickly following the event.
As a side question: is the event only published once the transaction is complete?
thanks for any insights,

The answer is the latter. You said it well: "Agents operate asynchronously with regard to the events they have registered for and the best you can do is hope for an agent to react very quickly following the event."
It works fairly well though, we have many agents that react to events, and it is usually just a few seconds after the operation occurs.

Usage Tracking - Cant perform insert operation inside a READ ONLY trans

Hello,
I have been experiencing the following error message when trying to install a row in our s_nq_acct table for USAGE TRACKING:
[nQSError: 16001] ODBC error state: S1000 code: 1456 message: [Oracle][ODBC][Ora]ORA-01456: may not perform insert/delete/update operation inside a READ ONLY transaction.
- I am able to manually insert rows via SQL*Plus whilst logged on as the same user as the Connection Pool
- The Read Only option is not ticked for the ODBC
Can anyone please help me with this?
Thanks,
Rhys

Hi rnm1978,
You were right!
I was being a bit retarded and had to simply switch the call interface on the connection pool to use the OCI and ensure the dta source name was that of the TNS names entry and not the system DSN.

Access Session variable inside Transaction

Hi All,
Is it possible to access session variables inside Transaction.
Create session variable.
Update session variable value
acccess Session variable.
(user session)
Regards,
Sachin

Hi Sachin,
Here is the snapshot:
1. Take session variable in a local JS variable in HTML page.
2. Create a transaction with a input type variable in Transaction Properties.
3. Create a Xacute query and link the above transaction.
4. Creata a iCommand applet on HTML page and link the query template:
<PARAM NAME="QueryTemplate" VALUE=".../QueryName">
Call the function in the below way in HTML:
Applet.getQueryObject().setParam(1,vaiable)
So, the session variable will go to TRX (BLT) and perform the operations as per your need..
You can pass it to other TRX by the same way.
To fetch the value: Create output type variable in TRX 2. Create Xacute query.
Get the value with : Applet.getValue(1,1)
Hope it is useful.
Best Regards,
Kedar

ORA-14551: cannot perform a DML operation inside a query

I have a Java method which is deployed as a Oracle function.
This Java method parses a huge XML & populates this data
into a set of database tables.
I have to call this Oracle function in a unix shell script using sqlplus.
Value returned by this function will be used by the shell script to decide
what to do next.
I am calling the Oracle Java function as follows in the shell script:
echo "SELECT XML_TABLES.RUN_XML_LOADER('$P1','$P2','$P3','$P4') FROM DUAL;\n" | sqlplus $DB_USER > $LOG
This gives error - "ORA-14551: cannot perform a DML operation inside a query".
If I have to add a AUTONOMOUS_TRANSACTION pragma to this Java function,
where to I add it considering, that the definition of the function is in a Java class.
Can we do it in call spec?
create or replace package XML_TABLES is
function RUN_XML_LOADER(xmlFile IN VARCHAR2,
xmlType IN VARCHAR2,
outputDir IN VARCHAR2,
logFileDir IN VARCHAR2) RETURN VARCHAR2 AS
LANGUAGE JAVA NAME 'XmlLoader.run
(java.lang.String, java.lang.String, java.lang.String, java.lang.String)
return java.lang.String';
end XML_TABLES;
If not is there any other way to acheive this?
Thanks in advance.
Sunitha.

If I have to add a AUTONOMOUS_TRANSACTION pragma to this Java function,You'd have to write a PL/SQL function that calls the JSP. But I would caution you about using that pragma. It does introduce tremendous complexity into processing.
As I see it you only need a function to return the result code so why not use a procedure with an OUT parameter?
Cheers, APC
Of course Yoann's suggestion of using an anonymous block would work too.

Memeber server in a domain connected with external trust. The agent operation failed, DPM could not communicate with the DPM agent. Error ID 270

I manually installed the agent on a member server in a domain (domainB) that has an external trust with the domain the DPM 2010 server, mydpmserver.domainA.int, is in.
I pointed the agent on myprotectedserver with setdpmserver -dpmservername mydpmserver.domainA.int
I successfully ran attach-productionserver.ps1 in DPM Management Shell.
When I click refresh in DPM 2010 Administrator Console/Management/Agents I get error id: 270

Cannot perform dml operation inside a query

I have created a function which does some dml opration.
when I use it in a through a transformation operator, and execute the map,
it throws the following error:
cannot perform dml operation inside a query
how to handle this?

Hi,
if you want to execute the dml within a mapping, use the pre or post mapping procress operator. Or use a sql*plus activity in the process flow.

Some how when its calling the insert_batch , its giving me the error in the logs as below:

Yes - and the exception is telling you EXACTLY what the problem is. You have a query
IF INSERT_BATCH(99,varSTMT) > 0 THEN
And you are performing a DML operation inside that query:
INSERT INTO BATCH_STATEMENT(QUEUE_ID,TABLE_ID,STATEMENT,QUEUE_SEQUENCE_ID)
    VALUES (numQUEUE_ID,numTABLE_ID,varSQL_STATEMENT,1);
Like the exception says: you can't do that.
You need to call the function using PL/SQL and capture the return value into a variable. Then test that variable:
myVar := INSERT_BATCH(99,varSTMT);
if myVar > 0 THEN

Using arthmetic operations inside a if conditions

hi,
How can I do a arithmetic operation inside if condition.

No i think you didnt get what i meant.
I want to use a command like this
if ( val1 - val2 ) > val3.
..... here goes everything
endif.
When everytime i want to execute such command i have to use another tempory value to solve the problem.
eg : -
val4 = val1 - val2.
if val4 > val3.
..... here goes everything
endif.

Modify, put and get : operations under transaction

Hello,
I use Coherence 3.0 with CONCUR_PESSIMISTIC.
When threads t1 and simultaneously t2 get the object obj1, they obtain it whitout waiting any lock. It's OK.
However, I've created a "modify" operation which is :
- get a transaction
- get the object obj1
- "modify it in my app" (for example obj = obj+1)
- put the new value
- commit transaction
This works but, in the following scenario, I get incoherent result, since get operations don't block.
Threads t1 and t2 modify the object obj1 at the same time. So, for example obj1 == 0 at the beginning. Then :
- t1 get a transaction
- t2 get a transaction
- t1 get the old obj1 value
- t2 get the old obj1 value
- t1 put the new value (obj1 == 1) in the cache;
- t2 put the new value (obj1 == 1) in the cache;
So at the end, obj1 == 1 in the cache, instead of 2!
obj1 = 0 + 1 (thread 1)
obj1 = 1 + 1 (thread 2, with old value == 1, thanks to thread 1)
I hope I'm clear enough...
So, my question is : what should I do?
Note that I can't say anything on the get/write operations ratio.
Should I use "put" operation to get the old value in modify operation (instead of get)? Won't it be heavy (in load term)?
Note that when I use TRANSACTION_GET_COMMITTED, the get of the "modify" operation doesn't block, but when I use TRANSACTION_REPEATABLE_GET, it is the get operation (the basic, not embedded in the modify operation) which is blocking.
I'd like : get basic operations don't be blocking and coherent "modify" operation. Is it possible?
Isn't it too heavy (in load) to block all the "modify" operation? What about versioning, to detect a change (between a get (old value) and put (new value))? Have code example?
Thanks for your advice,
Vincent

Hi Vincent,
It sounds like you can simply use locking in this scenario (cache locking semantics are similar to that of a Java synchronized keyword - if thread does use lock() it will block is there is contention, and if it doesnt use lock() it will not block at all):
read:
<code>
value = cache.get(key); // does not block
</code>
write:
<code>
try {
cache.lock(key, timeout); // will block if there is contention
value = cache.get(key);
cache.put(key, value + 1);
} finally {
cache.unlock(key);
</code>

Dimitri

Soa11g: DB Adapter Delete Operation and Transaction

Guys,
I need your help to understand the transaction flow in SOA 11g.
We have two table with primary and foreign key replationship.
Master Table: Employee (empId Primary Key)
Child Table : Department (empId Foreign Key)
Employee is associated with Department table with 1 to N relationship.
We have a composite with BPEL process. In Input of the BPEL we are getting 1 employee with many department. Our design is like below.
1) get the message.
2) read the empId from Input.
3) delete N records from Department table using DB adapter Delete Operation by passing empId as an Input. *(INVOKE 1)*
4) delete 1 records from Employee table by passing empId as an Input. *(INVOKE 2)*
I have following doubts.
1) Since without deleting the child records we can't delete parents. Before INVOKE 2(invoking DB adapter to delete parent record), I want to make sure that INVOKE 1 has completed ( all the child records have deleted successfully.) How to achieve this in BPEL?
2) let's say we have 5 child records. after deletion of 3rd record, DB gets down or some fault occurs ...will the entire transaction be roll back?
In this scenario we want to delete only 3 records without deleting the parent records . How to achieve this in BPEL.
3) what all are the transaction property available in SOA 11g to control the transactions.
Any inputs is appreciated!!
Thanks,
AB

Hi,
1 st DB adapter Delete operation(Child Table deletion) successfully completed with out DB Down or with out any errors.
2 nd DB adapter delete operation failed (Master Table Deletion) due to DB down (or) due to remote fault.
In the above scenario ... Is 1 st DB adapter delete operation gets roll back?
( or)
It commits even second one get failed...
In case of first one commits how can i achieve roll back of first one automatically if second one fails...
Any one can explain how the transaction concept works with DB adapters..?
Thanks&Regards,
