This chapter describes issues associated with Oracle Technology Adapters and the Oracle Fusion Middleware User's Guide for Technology Adapters. It includes the following topics:
This section describes general issues and workarounds. It includes the following topics:
This section describes issues and workarounds that are applicable to all adapters: Oracle AQ Adapter, Oracle JMS Adapter, Oracle Files/FTP Adapter, Oracle MQ Series Adapter, Oracle Database Adapter, and Oracle Socket Adapter.
This section includes the following issue:
ECID (Execution Context Identifier) propagation is not supported by Oracle Technology adapters. The ECID is used to keep track of message flow in Oracle Enterprise Manager, and hence this feature is not available in Oracle Technology adapters.
If an outbound adapter throws an exception with
GLOBAL_RETRY, then the retry configured at the outbound adapter level will not take effect. The retry falls back to the caller which could be a BPEL process. It is observed that the retry happens from the inbound to the BPEL process (caller of BPEL process) in either of the following transaction semantics in Oracle BPEL process:
<property name="bpel.config.transaction">requiresNew</property> <property name="bpel.config.oneWayDeliveryPolicy">sync</property>
<property name="bpel.config.transaction">required</property> <property name="bpel.config.oneWayDeliveryPolicy">sync</property>
If the adapter throws a
LOCAL_RETRY, then the retry configured at the outbound adapter level will take effect.
Note that for the inbound retry to work, Oracle BPEL process must not have any dehydration points.
During forceful shutdown of Oracle WebLogic Server, if the severs are processing data, then you may see JCA Binding Component error messages. These messages are benign.
Every time you use the Adapter Configuration Wizard to edit an adapter, the wizard uses the data you enter to recreate the adapter WSDL. If you made manual edits to the WSDL before, the Adapter Configuration Wizard will discard those changes the next time you edit the adapter.
The workaround for this issue is to make the same manual edits each time you use the Adapter Configuration Wizard.
This section describes the following issues and workarounds related to Oracle File and FTP Adapters:
It includes the following sections:
The Oracle File Adapter picks up a file from an inbound directory, processes the file, and sends the processed file to an output directory. However, during this process if a failover occurs in an SOA managed server, then the file may be lost because of the nontransactional nature of Oracle File Adapter. As a result, some files read by the inbound adapter may not be sent to the output directory. You must configure the Oracle File Adapter for high availability, to ensure that files are not lost during a failover.
When Oracle File and FTP Adapters read a Unicode XML file with byte order mark (BOM), a DOM parsing exception is thrown at runtime. If the Unicode XML file does not use BOM, then an exception is not thrown.
In case of debatching scenarios with XML payloads that have errors such as extra tags and spurious data, output files are created along with the rejected messages.
If Oracle File and FTP Adapters use logical directories for inbound or outbound operations, then JCA property updates from Oracle Enterprise Manager Console are not applied.
You must use a synchronous process in case of Oracle FTP Adapter debatching scenarios on FTP over SSL (FTPS) for large payloads. If a synchronous process is not used, then the FTP server throws the error code, 421.
The Chunked Read feature of Oracle FTP Adapter is not supported for SFTP (Secure FTP) using SSH transport.
When a dynamic file name is specified for an output file, the
Append property must not be edited. However, the Oracle Enterprise Manager Fusion Middleware Control Console allows you to edit the
Append property even when you specify a dynamic file name for an output file. Ensure that you do not edit the
Append property when you specify a dynamic file name for an output file.
When using a dynamic file name the value of the
Append property must be
false. By default, the value of the
Append property is
false and this must not be edited while using a dynamic file name.
When an Oracle File Adapter processes a file with some invalid records, the invalid records are sent to the rejected messages directory, whereas, the valid records are lost. To ensure that no data is lost, input files with invalid data must be sent to the error archive queue. You must set the following properties in the WSDL file for the Read file operation to ensure that input files with errors are sent to the error archive queue:
If you enable payload validation when using attachments, the Oracle FTP Adapter fails with a
java.lang.NullPointerException and logs an error like: "FtpIn FtpInAdapter Service FtpIn was unable to perform delivery of inbound message to the composite".
When using attachments, disable payload validation. For Attachments, payload validation is unnecessary.
This section describes the following issue and workaround related to Oracle JCA Adapter for AQ:
It includes the following section:
In an SOA project that contains outbound Oracle JCA Adapter for AQ, Mediator or BPEL, and an inbound Oracle JCA Adapter for AQ, when you select the business payload option as Field within the Object, the national characters are garbled. This issue depends on server locale encoding and exists only on native locale. However, when the server is running on UTF-8 encoding, this issue does not exist.
It is recommended that you use Oracle Adapter for Oracle Applications to dequeue from queues in E-Business Suite Applications and not Oracle JCA Adapter for AQ.
When using the Adapter Configuration Wizard to configure the object payload, you may configure the Business Payload as either:
Field within the Object
If you select Field within the Object, and you do not check the Access to non-payload fields also needed option, your composite may fail at run time with an
The workaround for this issue is to always select the Access to non-payload fields also needed option when you configure the Business Payload by selecting the Field within the Object option.
For more information, see "The Adapter Configuration Wizard Object Payload Page" in the Oracle Fusion Middleware User's Guide for Technology Adapters.
If you use Oracle Enterprise Manager Console to enable payload validation at the
SOA-INFRA level, then for inbound Oracle JCA Adapter for AQ (including B2B adapters or Oracle Adapter for Oracle Applications that use Oracle JCA Adapter for AQ), then Oracle recommends that you use the following block in your payload XSD:
This section describes the following issues and workarounds related to Oracle JMS Adapter:
Anytime the exception weblogic.messaging.kernel.QuotaException: Quota blocking time exceeded and no quota available is encountered, WLS JMS provider allows flow control settings that you can tweak to control the number of messages that are produced/consumed.
For more information about tweaking the control settings, see
The following is an example of the flow control settings used and the various thresholds for a message carrying a payload size of 5k:
Config JMSServer: Message Buffer Size:5000 Config JMSConnectionFactory: Flow Control: Flow Maximum: 30 Flow Minimum: 1 Flow Interval: 10 Flow Step: 10 check Flow Control Enabled Default Delivery: Send Timeout: 3000000 Config JMS Destinations: Bytes Threshold High: 50000 Bytes Threshold Low: 50 Messages Threshold High: 100 Messages Threshold Low: 1 Set Quota
While migrating a project from one environment to another, Oracle JMS Adapter Wizard populates the Destination and JNDI name fields in edit mode in the following pages:
Consume Operation Parameters page
Produce Operation Parameters page
Request Operation Parameters page
Reply Operation Parameters page
Request/Reply Operation Parameters page
However, if you click Next, the Adapter Configuration Wizard validates whether this is a valid destination, and accordingly, displays a warning message if found to be invalid. You have the option to proceed or enter a valid destination.
When you use Oracle JMS adapter with a distributed topic deployed in a cluster, the scenario would result in more messages processed than the actual number of messages passed to the topic.
Each subscriber to the topic is handed a copy of the message to be processed by WLS JMS. So, the number of processed messages will be equal to the number of active subscribers on the distributed topic. This is a known behavior of Oracle WebLogic JMS in Oracle WebLogic Application Server 10.3.
When using the Oracle JMS Adapter in an Enqueue-Dequeue Request-Reply scenario, if you change the Queue name (Inbound Queue and Reply Queue) to a new value, the old queue is still polled.
The workaround for this issue is to configure the new Queue name and redeploy the composite.
This section describes the following issues and workarounds related to Oracle Database Adapter:
While configuring an outbound Oracle Database Adapter to perform a SELECT operation, if you select Get Active Unit of Work in the Adapter Configuration Wizard - Advanced Option page, then the value of the
GetActiveUnitofWork property is not saved in the
The workaround for this issue is to manually add this property in the
.jca file of the Oracle Database Adapter, as shown in the following example:
<property name="GetActiveUnitOfWork" value="true"/>
Consider a scenario in which the Oracle Database Adapter retries the transaction at remote fault (that is, when the database is down) in a condition where the binding fault retry is specified in the
composite.xml file, and there is no fault policy defined. In such a scenario, the binding fault retry performed by the Oracle Database Adapter is not captured in the Audit Trail in the Oracle Enterprise Manager Console.
If you re-create an Oracle Database PL/SQL statement or other schema object (such as a data type), or recompile a package body, and re-deploy a SOA composite that uses the Oracle Database Adapter, then the Oracle Database Adapter runtime will throw an ORA-00902: invalid datatype exception.
The workaround for this issue is to set the following Oracle WebLogic Server properties:
Initial Capacity: 0
Statement Cache Size: 0
Adapter Connection Pool:
Initial Capacity: 0
If your SOA composite is incompatible with these property settings, the workaround for this issue is to stop and start the Oracle WebLogic Server.
For more information, see:
"Configuring JDBC Data Sources" in the Oracle Fusion Middleware Configuring and Managing JDBC for Oracle WebLogic Server
"Connection Management" in the Oracle Fusion Middleware Programming Resource Adapters for Oracle WebLogic Server.
In this release, Oracle recommends that you use the new distributed polling approach based on skip locking. When editing an Oracle Database Adapter service which has a
MarkReservedValue set, that value will be removed to enable the new best practice.
To use the old distributed polling approach based on a reserved value, select the value from the drop down menu.
The Oracle Database Adapter stored procedure interface does not support the following data types in SQL Server 2008:
This section describes the following issues and workarounds related to Oracle MQ Series Adapter:
Oracle MQ Series Adapter does not support asynchronous request-response pattern (where Mediator is the server).
If you select the outbound resource as XA, then the Oracle MQ Series Adapter throws an exception and does not retry because it does not support an outbound retry with outbound resource as XA. On the other hand, if the outbound resource is non-XA, then the retry happens correctly.
When working with more than one managed server, if you try to bring down the channel, then Oracle MQ Series hangs. This occurs in both Windows and UNIX operating systems.
Standard Java encodings and their mappings are provided with the MQ Series Adapter but the Adapter Configuration Wizard does not support addition of additional Java encodings that you may require.
To add support for the standard Java encodings that are not provided in the list, you can perform the following steps:
MQSeriesAdapter.jar file from the
mq.properties file from the MQSeriesAdapter.jar file.
Add the entry in the
mq.properties file. This file has two entries for a mapping between MQ Series encoding and Java encoding. For each new encoding that you require, you must make two entries to the
mq.properties file. Make an entry for the MQ Series encoding to the corresponding Java encoding and the other entry for the Java encoding to the corresponding MQ Series encoding.
Oracle JCA Adapter for MQ Series is certified with MQ Series version 126.96.36.199. If you are using XA transactions, then you must configure the server connection channel with a level of conversation sharing set to 0.
When using the Oracle MQ Series Adapter in an Enqueue-Dequeue Request-Reply or Dequeue-Enqueue Request-Reply scenario, if you change the Queue name (Inbound Queue and Reply Queue) to a new value, the old queue is still polled.
The workaround for this issue is to configure the new Queue name and redeploy the composite.
If you forcefully shutdown the Inbound Queue Manger using the
-i option (such as
QUEUE-MANAGER), and then bring it up again, the Oracle MQ Series Adapter does not reconnect properly:
The Open Input count of the Inbound Queue is reduced from the default value 2 to 1 and the Inbound message is delivered to the Outbound Queue and then put back to the Inbound queue. The Oracle MQ Series Adapter repeats this infinitely.
In some cases, the Open Input count is reduced from the default value 2 to 1 and the messages are just delivered to the Outbound Queue.
The workarounds for this issue are:
Configure the SOA instances in non-blocking mode.
Restart the inbound partner link.
Stop and start the managed instance.
This section describes the following issue and workaround related to Oracle Socket Adapter:
Oracle Socket Adapter is not supported on a cluster-based environment. If you try to deploy an inbound Oracle Socket Adapter in a clustered environment, then one of the managed servers throws an error message that the server's port is already in use.
When configuring the Oracle Socket Adapter using the Adapter Configuration Wizard, at step 4 of 7, if you select either of:
Inbound Synchronous Request/Reply
Then, at Adapter Configuration Wizard step 5 of 7, note the following:
If you want to override the default port for the given socket connection JNDI name, check Specify Host and Port.
If you check Specify Host and Port, you must enter a value for Host Name. Note the following:
If your host is associated with only one IP address, that is, if it has only one Network Interface Card (NIC), enter
If your host is associated with more than one IP address, that is, has more than one NIC, enter the one IP address you want the Oracle Socket Adapter to listen on.
The Oracle Socket Adapter can listen on only one specific IP address. The Oracle Socket Adapter cannot listen on multiple IP addresses.
This section describes the following issue and workaround related to Native Format Builder:
In the Specify Delimiter's page of the Native Format Builder wizard, the
White space (any number of tab, space) option in the Delimited by list is not supported.
When payload validation is enabled, it may fail with a
java.lang.ClassCastException for payloads greater than 10 MB in size.
For more information, see "Payload Validation" in the Oracle Fusion Middleware User's Guide for Technology Adapters.
There are no known configuration issues at this time.
This section describes documentation errata for Oracle Fusion Middleware User's Guide for Technology Adapters. It includes the following topics:
Section 188.8.131.52, "Undying" in Chapter Oracle JCA Adapter for Database states that the new Undying property is supported. Instead, Undying is now always true, so the configuration property has been removed.
When you drag and drop Third Party Adapter from the Service Adapters list to the Exposed components swim lane in the
composite.xml page and click the Help button, the online help does not define the JCA File attribute.
The definition should read: The JCA file provides adapter configuration information for the service.
The title of this help topic should read: Third Party Adapter.
The bread crumbs for this help topic should read: Component Palette for SOA Composite Editor > Adapter Services > Third Party Adapter > Adapter Configuration Wizard.
In the Adapter Configuration Wizard for an Oracle JMS Adapter, when Message Body Type is MapMessage, the online help for the Consume Operation Parameters page does not define the Payload attribute.
The definition should read: Optionally specify the name of the
MapMessage entry you want to designate as the payload. All other
MapMessage entries are converted to adapter properties identified by
xxxx is name of the
MapMessage entry. If you do not configure the Payload attribute, then the entire
MapMessage is converted to XML and the XML file is transferred as the payload.
In the Adapter Configuration Wizard for an Oracle JMS Adapter, when Message Body Type is MapMessage, the online help for the Consume Operation Parameters page does not define the As Attachment attribute.
The definition should read: Check this option to instruct the Oracle JMS Adapter to opaquely copy the payload as an attachment. This allows you to transfer a large amount (of often binary) data efficiently, without processing its contents within the composite application.
In the Oracle Fusion Middleware User's Guide for Technology Adapters, the Oracle Socket Adapter chapter is missing a topic on how to specify a TCP port in a configuration plan for an Oracle Socket Adapter.
To do so, perform the following steps:
Add the following code to your configuration plan XML file:
<service name="Receive"> <property name="Port"> <replace>2222</replace> </property> <binding type="jca"/> </service>
Add a port property to your
.jca file as follows:
<property name="Port" value="Port"/>
Add the port property to your
composite.xml file under the service element and specify a default value (in this example, 1111):
<service name="Receive" ui:wsdlLocation="Receive.wsdl"> <interface.wsdl interface="..." /> <binding.jca config="Receive_tcp.jca"/> <property name="Port" type="xs:string" many="false" override="may">1111</property> </service>
Deploy your composite with the configuration plan.
When deployed, the Oracle Socket Adapter will listen on port 2222, as given in the configuration plan.
If you deploy the composite without a configuration plan or if the configuration plan does not override the
Port property, then the Oracle Socket Adapter will listen on the socket that the
composite.xml file's default
Port property specifies (in this example, port 1111).
The beginning of Section 9.6, "JDBC Driver and Database Connection Configuration" in the Oracle Fusion Middleware User's Guide for Technology Adapters reads as follows:
"In this release, Oracle JCA Adapters are certified against the following third-party databases using Oracle WebLogic Server Type 4 JDBC drivers:
Microsoft SQL Server 2008
It should read as follows:
"In this release, Oracle Database Adapter is certified against the following third-party databases using Oracle WebLogic Server Type 4 JDBC drivers:
Microsoft SQL Server 2005, 2008
DB2/UDB 9.5 and later FixPaks"
The following note applies only to Section 10.4.1.3, "Asynchronous Request-Response (Oracle BPEL PM As Client)" and Section 10.4.1.9, "Asynchronous Request-Response (Oracle Mediator As Client)"It does not apply to Sections 10.4.1.5, 10.4.2 and 10.4.3.
Note:For Oracle MQ Series Adapter in an asynchronous outbound request/reply scenario, properties are differentiated by an
(Dequeue)label in Oracle Enterprise Manager Console. For example,
QueueName(Enqueue)is used for putting a message and
QueueName(Dequeue)is used for dequeuing the reply.
When using Oracle Enterprise Manager Console to edit Oracle MQ Series Adapter properties in this scenario, note the following:
If you change the
ReplyToQueueName(Enqueue) property, you must also change the
QueueName(Dequeue) property to the same value.
If you change the
MessageId(Dequeue) property, you must also change the
MessageId(Enqueue) property to the same value.
If you change the
CorrelationId(Dequeue) property, you must also change the
CorrelationId(Enqueue) property to the same value.
