Release the connection in JMS Adapter

Hi,
I’m sending the message to JMS queue (queue is running in weblogic server) using JMS Adapter in BPEL. My question is how to release the weblogic connection once the message produced to queue. It is happen automatically or we have to release the connection explicitly. If it explicit handle means how to do it?
It would very helpful for me if you send any reference doc or url about this.
Thanks in Advance.
Thanks
Chandramohan

The JMS adapater of SOA will handle this for you. You do not have to do anything with closing connections.

Does transaction manager also releases the connections ?

Hi All,
I've a doubt regarding release of connection in transaction handling scenarios in EJB.
Let us assume I have an EJB method associated with a transaction attribute as Requires New (i.e. the ejb method is associated with container managed transaction).
Within that method two diffreent databasess are accessed, connections are created, databases are updated but connections are not realeased.
The code goes similar to the one given below -
public void beanMethod1()
InitialContext cntx = new InitialContext();
javax.sql.DataSource ds1 = cntx.lookup("dataSourceName1");
javax.sql.DataSource ds2 = cntx.lookup("dataSourceName2");
java.sql.Connection conn1 = ds1.getConnection();
ds1.setAutoCommit(false);
PreparedStatement pst1 = ds1.prepareStatement("Qyery1");
pst1.executeUpdate();
java.sql.Connection conn2 = ds2.getConnection();
ds2.setAutoCommit(false);
PreparedStatement pst2 = ds2.prepareStatement("Qyery2");
pst2.executeUpdate();
Now in this context my doubt is - will the transaction manager, along with handling commit/rollback, release the connections also (once commit/rollback is over) ? Or releasing of connections need to be handled in the bean method ?
If releasing connections has to be handled in the bean method, then how does transaction manager execute a commit/rollback on a released connection ?
The same doubt can be extended to bean managed transaction also where transaction boundarry is demarcated using javax.transaction.UserTransaction object's begin(), commit() and rollback() methods.
It will be a real help if anyone please throw some light on this doubt.
Thanks in advance,
Sourav

Hi,
Your code needs to release (i.e., close) the connections it uses; this is outside the TM responsibility scope.
The commit or rollback is not a problem, because the corresponding XAResource (which is the
transaction manager's handle to your connection) can be used even after your connection
has been closed in the application code. That is the catch about XA, and it allows the whole
mechanism of connection pooling and DataSources to work properly.
Hope that helps,
Guy

Oci_close does not release the connection when using DRCP

Hello everyone,
we are currently testing the deplyment of DRCP with 11g. I have the whole thing setup (correctly to my best knowledge), but I am facing an issue. The call to oci_close does not seem to release the connection to the pool as I would expect and therefore we see similar behavior like we were getting without using the DRCP.
Our setup is using two RAC instances running 11.1.0.6.0, I am using PHP 5.1.6 with PECL installed oci8 1.3.4. The DRCP pool is configured and started, each with 100 max servers.
When the webserver is idle it looks, well, idle.
SQL> SELECT INST_ID,NUM_BUSY_SERVERS FROM GV$CPOOL_STATS;
INST_ID NUM_BUSY_SERVERS
1 0
2 0
The script is as simple as it gets:
<?php
$c = oci_pconnect('scott','tiger','IWPPOOLED');
$s = oci_parse($c, 'select * from emp');
$r = oci_execute($s, OCI_DEFAULT);
oci_close($c);
sleep(30);
?>
What I would expect is that the script would connect to the pool, do the work for a tiny moment and then release the connection for usage by other script.
But after I point the browser to the script, I get a 30 second loading time (as expected) but the server is busy all the time, like this:
SQL> SELECT INST_ID,NUM_BUSY_SERVERS FROM GV$CPOOL_STATS;
INST_ID NUM_BUSY_SERVERS
1 0
2 1
After the 30 second sleep, it is released and busy servers are back to 0.
If I load the server with ab using 256 connections:
ab -n 1000000 -c 256 -k http://mywebserver/ocitest.php
the pool is maxed out and the connects are stalling:
SQL> SELECT INST_ID,NUM_BUSY_SERVERS FROM GV$CPOOL_STATS;
INST_ID NUM_BUSY_SERVERS
1 95
2 95
My network config for this service is following:
IWPPOOLED =
(DESCRIPTION =
(LOAD_BALANCE=ON)
(FAILOVER=ON)
(ADDRESS = (PROTOCOL = tcp)(HOST = 10.1.16.33)(PORT = 1521))
(ADDRESS = (PROTOCOL = tcp)(HOST = 10.1.16.34)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = IWP)
(SERVER=POOLED)
(FAILOVER_MODE=
(TYPE=SELECT)
(METHOD=BASIC)
(RETRIES=5)
(DELAY=3)
The phpinfo() look like this:
OCI8 Support enabled
Version 1.3.4
Revision $Revision: 1.269.2.16.2.38.2.20 $
Active Persistent Connections 1
Active Connections 1
Oracle Instant Client Version 11.1

oci8.persistent_timeout -1 -1
oci8.ping_interval -1 -1
oci8.privileged_connect Off Off
oci8.statement_cache_size 20 20
I am using the instant client for 11g
Any ideas?
Thanks!
Michal

Don't forget to use oci_free_statement($s); See "Closing Oracle Connections" in The Underground PHP and Oracle Manual. (I was just simplifying this example today for the next release of the manual).
You may also see the "dedicated optimization", where a pooled server in a non- maxed-out pool is retained (unless needed by another PHP process) under the assumption that the initial PHP process might become active again. See http://www.oracle.com/technology/tech/php/pdf/php-scalability-ha-twp.pdf
Feel free to email me offline (see my profile) if there are questions/data you don't want to post.

Also the BPEL process containing JMS adapter is not able to pick up data from JMS queue.
The same adapter was used in ESB service as well, which is working fine. There are no issues in ESB JMS Adapter connecting to JMS Queue of TIBCO EMS server.
Your help is appriciated.

Try the BPEL / SOA forum, you'll get more help there.

someone has an idea about this?

Hi,
It looks like you have some "wrong" concepts.
First you say that:
Now in WS1, there is no schema
later on you are telling
have then check the command
select * from SAPBOS.SVERS and it worked.
So, do you have a schema or don't you?
Let me try to understand what you have done, for your description
1) you have a system called BOS. On this system you have a schema called SAPBOS.
2) you did a system copy from BOS to W1S. Guessing -> You did a restore from a BOS
Now your SAPW1S has "dissapeared"
am I understandin it properly?
If so, you should think a little.
You have restored a backup from BOS ( DB name BOS, SCHEMA BOS, tablespace names PSAPBOS ) into W1S
Restoring a backup will not change the schema name ( AFAIK, there is no simple way of doing so )
Restoring a backup will not change the tablespaces names ( in Oracle 10g you can do this, but has to be done manually )
Restoring the backup will not change the DB name. The System copy procedure ask you to create a script that will perform this last change.
So, at the end of the process you have a DB called W1S, with a schema called SAPBOS and tablespaces called PSAPBOS.
As mentioned before there is no simple way of changing the schema name.
If you need/want/desire to do so then you cannot use BACKUP/RESTORE for system copies. You must use the R3Load method ( take all data out of the DB and then take all the data in on the new system )

EJB3 : suspend JTA transaction does not release the connection in the XA DS

Hi all,
I did a test and after suspending a JTA transaction I note that in the xa datasource the activeconnection = 1.
So is it normal because I was thinking that when I suspend the transaction the teh connection is released and then after a transaction resume I could continue the transaction with another connection of the xa datasource ?
Thank you for all..
Christophe.

It's a long time ago, but did you ever solve this problem?
I'm having the same issue with OSB writing to a WLS8.1 JMS queue.
I have a development OSB server which works fine.

The connection of AQ adapter is inactive when restart the server.

I'm facing an issue in our project.
I create an aq adapter to read the aq (the aq is created iin a MIS database server), and deploy it to SOA server(Oracle SOA Suite, 10.1.3.3). I'm finding that a connection to MIS database from AQ Adapter is created and kept to be running periodary.
If, if, the MIS database server is re-start. The issue occurs. The adapter can't read aq any more unless restart the SOA server .
My colleague tells me that he is facing the same issue in creating a dbadapter to polling data from table.
Is there a solution that we needn't to restart the SOA server? Because in production, it will impact many business application to restart the SOA server.
Thanks.
Joseph

It's resolved.
If SOA server is launched when MIS database is down, the adapter connected with MIS database will be marked as inactive. So after MIS database re-start, the adapters doesn't work yet. To enable the adapters, do the following steps:
1. login ESB console
2. select the adapter wich is connected with MIS database
3. Disable it and Enable again.
It's OK now.

CUCM unexpectedly release the connect

Can anyboydy give a hint ?
I have an Avaya - Cisco 2901 -CUCM H323 connection.
If i ring from outside to local phone then call dropped after 5 sec. In the h225 log i see following sequence :
(VG -> CUCM) SETUP
(VG -> CUCM) CALL_PROC
(VG <- CUCM) ALERTING
(VG <- CUCM) NOTIFY
(VG <- CUCM) CONNECT
(VG <- CUCM) NOTIFY
(5 sec wait)
(VG <- CUCM) RELEASE
If I call from local to outside then connection established and called party picks up the phone, but calling party doesn't get any sign of that.
What can cause the problem ?

JMS Adapter setting the header data of MQ message

Hi All,
I need to set the properties in JMS adapter for setting the header data of MQ message.
JMS_IBM_MQMD_Format = MQFMT_NONE.
Thanks in advance
Ravijeet

Hi All,
I am stuck in a typical XI issue.......I have a scenario where my input to XI is IDoc and output is xml message going to IBM MQ.
The IDoc is sending some chineese character which is fine is SXMB_MONI Integration server and also fine in the payload of message monitoring, so feel the message is going fine from XI to MQ.
But the receiver EDI system which is picking the message from MQ queue says the chinese characters are getting corrupted. They say that you need to set the additional properties in MQ header data
JMS_IBM_MQMD_Format = MQFMT_NONE.
How do I do this in communication channel for jms adapter ? How to I set the MQ header data in jms communication channel ?
Thanks in advance

LMS 4.2 is not releasing SSH connections of the devices

Hello!
We have LMS opens SSH sessions to Nexus 5000 devices as part of some jobs.
These SSH connections are not being released by LMS as soon as jobs are completed, which leads the N5K devices to hang without any way of managing them remotely.
We see these connections as idle on the nexus devices (which also should kill these sessions, but this is not the issue).
We have found a known bug:
CSCty90928
LMS Pari jobs are not releasing SSH,telnet connections of the devices
Symptom:
Telnet/SSH connections are not released by LMS
Conditions:
Pari collections jobs are not releasing the connections after the Job completed
Workaround:
None
This bug is categorized as "2 – severe" and is in "Open (Postponed)" status.
I have a few questions, if anyone can assist:
1.) What is the ETA to fix this bug?
2.) Are there any other known bugs matching what we see (documented public bugs, with bug ID's, internal bugs or even undocumented bugs).
3.) Is there any released or unreleased (even yet to be tested by TAC) patch we can use that should fix the issue?
4.) Is there any way to adjust LMS idle timeout of SSH/Telnet sessions (I couldn't find it in the GUI, but maybe there is a way to change this parameter using a perl script or modifying one of LMS properties files)?
Thanking in advance, Udi Dahan.

Hello Ehud
From N5k side we have submitted bug CSCty00044
Currently there is no fix for it and our debelopment team is catively working on it and investigating the issue in the lab.
To get ETA for the release I would suggest you reach your account team and check with them how fast fixed release will be available.

Calling Foreign JMS in SOA Suite 11g JMS Adapter

Hi,
Just want to get some guidance in the implementation of Foreign JMS in WebLogic 10.3.
I followed the creation of the Foreign JMS Server using this document:
http://download.oracle.com/docs/cd/E12839_01/apirefs.1111/e13952/taskhelp/jms_modules/foreign_servers/CreateForeignServers.html
I am trying to connect to a remote Weblogic 10.3 JMS queue but cannot get pass the JDev wizard stage.
I need to call the foreign JMS via the Fusion 11g JMS Adapter but cannot lookup the destination from the JDev wizard. My composite will produce a message that will end up in the remote queue.
Has anybody got this to work? Is this supported in JMS Adapter? I've read quite a few using MDB to call the Foreign JMS but not JMS Adapter.
Regards,
Robert

Please refer to the following document that shows how to access remote wls jms queues and topics. This is the preferred way when accessing remote wls destinations.

How to install Oracle AS JMS Adapter on Websphere (or any J2EE server)

Hi,
We have a requirement in which the client wants to connect to the OC4J JMS running in SOA Suite (Oracle Application Server 10.1.3.4).
They are using Websphere. We are exploring ways by which they can connect from Websphere application to Oracle AS OC4J JMS.
One option is - deploy the Oracle AS JMS adapter in Websphere and then use it to connect to the OC4J JMS.
Please let us know if this is the right approach. Also, if so, kindly point to the documentation regarding how to install the JMS adapter on 3rd party J2EE servers such as websphere.
Rgds,
Amit

While searching the knowledge base I found the following note, which seems to suggest that Oracle Adapters are not deployble on other J2EE application servers:
Support For Jca Adapter In Other Application Servers Like Jboss [ID 1114738.1]
==============================================
From the statements in documentation it may be implied that jca adapter should be deployable on any application server that is compliant with j2ee/jca. Please note that this cannot be implied at this time and jca adapter cannot be deployed on other application servers than OAS in BRM 731 due to some technical constraints. So currently we can support only OAS and not JBoss or another application server , in BRM 731. The documentation will be updated accordingly to reflect this.
