This chapter describes issues associated with Oracle Fusion Middleware administration. It includes the following topics:
This section describes general issue and workarounds. It includes the following topic:
Section 4.1.1, "Fusion Middleware Control May Return Error in Mixed IPv6 and IPv4 Environment"
Section 4.1.3, "Limitations in Cloning Oracle Virtual Directory"
If your environment contains both IPv6 and IPv4 network protocols, Fusion Middleware Control may return an error in certain circumstances.
If the browser that is accessing Fusion Middleware Control is on a host using the IPv4 protocol, and selects a control that accesses a host using the IPv6 protocol, Fusion Middleware Control will return an error. Similarly, if the browser that is accessing Fusion Middleware Control is on a host using the IPv6 protocol, and selects a control that accesses a host using the IPv4 protocol, Fusion Middleware Control will return an error.
For example, if you are using a browser that is on a host using the IPv4 protocol and you are using Fusion Middleware Control, Fusion Middleware Control returns an error when you navigate to an entity that is running on a host using the IPv6 protocol, such as in the following situations:
From the Oracle Internet Directory home page, you select Directory Services Manager from the Oracle Internet Directory menu. Oracle Directory Services Manager is running on a host using the IPv6 protocol.
From a Managed Server home page, you click the link for Oracle WebLogic Server Administration Console, which is running on IPv6.
You test Web Services endpoints, which are on a host using IPv6.
You click an application URL or Java application which is on a host using IPv6.
To work around this issue, you can add the following entry to the /etc/hosts file:
nnn.nn.nn.nn myserver-ipv6 myserver-ipv6.example.com
In the example, nnn.nn.nn.nn is the IPv4 address of the Administration Server host, myserver.example.com.
Some JSF applications may experience a memory leak due to incorrect Abstract Window Toolkit (AWT) application context classloader initialization in the Java class library. Setting the oracle.jrf.EnableAppContextInit system property to true will attempt eager initialization of the AWT application context classloader to prevent this leak from occurring. By default, this property is set to false.
Note the following limitations in cloning Oracle Virtual Directory
When you are cloning Oracle Virtual Directory, the Oracle instance name in the source environment cannot be the same as the Oracle instance name in the target environment. The Oracle instance name in the target must be different than the name in the source.
After you clone Oracle Virtual Directory from one host to another, you must add a self-signed certificate to the Oracle Virtual Directory keystore and EM Agent wallet on Host B. Take the following steps:
Set the ORACLE_HOME and JAVA_HOME environment variables.
Delete the existing self-signed certificate:
$JAVA_HOME/bin/keytool -delete -alias serverselfsigned -keystore ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/keys.jks -storepass OVD_Admin_password
Generate a key pair:
$JAVA_HOME/bin/keytool -genkeypair -keystore ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/keys.jks -storepass OVD_Admin_password -keypass OVD_Admin_password -alias serverselfsigned -keyalg rsa -dname "CN=Fully_qualified_hostname,O=test"
Export the certificate:
$JAVA_HOME/bin/keytool -exportcert -keystore ORACLE_INSTANCE/config/OVD/ovd_component_name/keystores/keys.jks -storepass OVD_Admin_password -rfc -alias serverselfsigned -file ORACLE_INSTANCE/config/OVD/<ovd_component_name/keystores/ovdcert.txt
Add a wallet to the EM Agent:
ORACLE_HOME/../oracle_common/bin/orapki wallet add -wallet ORACLE_INSTANCE/EMAGENT/EMAGENT/sysman/config/monwallet -pwd EM_Agent_Wallet_password -trusted_cert -cert ORACLE_INSTANCE/config/OVD/<ovd_component_name/keystores/ovdcert.txt
Stop and start the Oracle Virtual Directory server.
Stop and start the EM Agent.
This section describes configuration issues and their workarounds. It includes the following topics:
Section 4.2.1, "Must Stop Oracle SOA Suite Managed Server Before Stopping soa-infra"
Section 4.2.2, "Configuring Fusion Middleware Control for Windows Native Authentication"
Section 4.2.3, "Fusion Middleware Control Does Not Keep Column Preferences in Log Viewer Pages"
9035410
Using Fusion Middleware Control, if you stop a Oracle SOA Suite Managed Server before you stop soa-infra, then you start the Managed Server, the soa-infra application is not restarted automatically. If you try to restart the soa-infra, you will received an error. When you encounter the problem, you cannot close the dialog box in the browser, so you cannot take any further actions in Fusion Middleware Control.
To avoid this situation, you should stop the Managed Server, which stops all applications, including the soa-infra application. To start the Managed Server and the soa-infra, start the Managed Server.
To close the browser dialog box, enter the following URL in your browser:
http://host:port/em
To use Windows Native Authentication (WNA) as the single sign-on mechanism between Fusion Middleware Control and Oracle WebLogic Server Administration Console, you must make changes to the following files:
web.xml
weblogic.xml
These files are located in the em.ear file. You must explode the em.ear file, edit the files, then rearchive the em.ear file. Take the following steps (which assume that while the front end is on Windows, the em.ear file is on UNIX):
Set the JAVA_HOME environment variable. For example:
setenv JAVA_HOME /scratch/Oracle/Middleware/jrockit_160_05_R27.6.2-20
Change to the directory containing the em.ear, and explode the file. For example:
cd /scratch/Oracle/Middleware/user_projects/applications/domain_name JAVA_HOME/bin/jar xvf em.ear em.war JAVA_HOME/bin/jar xvf em.war WEB-INF/web.xml JAVA_HOME/bin/jar xvf em.war WEB-INF/weblogic.xml
Edit web.xml, commenting out the first login-config block and uncommenting the login-config block for WNA. (The file contains information about which block to comment and uncomment.) When you have done this, the portion of the file will appear as in the following example:
<!--<login-config>
<auth-method>CLIENT-CERT</auth-method>
</login-config>
-->
<!--
the following block is for Windows Native Authentication, if you are using
WNA, do the following:
1. uncomment the following block
2. comment out the previous <login-config> section.
3. you also need to uncomment a block in weblogic.xml
-->
<login-config>
<auth-method>CLIENT-CERT,FORM</auth-method>
<form-login-config>
<form-login-page>/faces/targetauth/emasLogin</form-login-page>
<form-error-page>/login/LoginError.jsp</form-error-page>
</form-login-config>
</login-config>
<security-constraint>
.
.
.
<security-role>
<role-name>Monitor</role-name>
</security-role>
Edit weblogic.xml, uncommenting the following block. (The file contains information about which block to uncomment.) When you have done this, the portion of the file will appear as in the following example:
<!--
the following block is for Windows Native Authentication, if you are using
WNA, uncomment the following block.
-->
<security-role-assignment>
<role-name>Admin</role-name>
<externally-defined/>
</security-role-assignment>
.
.
.
<security-role-assignment>
<role-name>Deployer</role-name>
<externally-defined/>
</security-role-assignment>
Rearchive the em.ear file. For example:
JAVA_HOME/bin/jar uvf em.war WEB-INF/web.xml JAVA_HOME/bin/jar uvf em.war WEB-INF/weblogic.xml JAVA_HOME/bin/jar uvf em.ear em.war
In Fusion Middleware Control, you can reorder the columns in the pages that display log files and log file messages. However, if you navigate away from the page and then back to it, the columns are set to their original order.
When you change the log file format note the following:
When you change the log file format from text to xml, specify the path, but omit the file name. The new file will be named log. xml.
When you change the log file format from xml to text, specify both the path and the file name.
There are no known issues at this time.
