11g Release 1 (184.108.40.206)
This document contains information about the new features and known issues for Oracle Traffic Director 220.127.116.11.
The following are the new features in Oracle Traffic Director 18.104.22.168. For more information, see Oracle Traffic Director Administrator's Guide.
Oracle Traffic Director now allows administrators to handle back-end application maintenance efficiently. Administrators can now configure a custom response code and an HTML page for an origin server pool when all the servers in the origin server pool are offline. This capability, combined with the ability to drain traffic to an application server allows administrators to minimize and handle an application maintenance window.
Oracle Traffic Director now supports the modern SSL protocols, TLS 1.1 and TLS 1.2.
Oracle Traffic Director now supports a generic health check hook-up mechanism, where customers can write their own health check programs/scripts to monitor the health of specific origin servers. An external executable is especially useful for a protocol-level health check monitor for the origin servers when Oracle Traffic Director is doing TCP load balancing.
Oracle Traffic Director can now be configured within a Solaris Zone/Container and provide high availability for IP over InfiniBand (IPoIB) on Solaris. There is no longer a restriction that Oracle Traffic Director must be installed in a global zone to provide high availability for Solaris.
This capability requires Oracle Traffic Director 22.214.171.124 to be deployed on Solaris 11.2 with update SRU3 or higher.
Oracle Traffic Director now monitors the status of origin servers, and displays the status in the origin servers page in the user interface. Oracle Traffic Director can also show status for dynamically discovered origin servers if available and enabled.
Oracle Traffic Director now supports optionally associating an origin server pool with an external HTTP (forward) proxy server so that all origin servers within this pool are reachable via this external proxy server. This feature supports an environment where access to intended origin servers are restricted through corporate proxy servers.
Oracle Traffic Director can now rewrite HTTP request/response headers and entity data by applying the standard regular expression syntax rules (compliant with
sed regular expression syntax). You will need to manually edit the Oracle Traffic Director load balancer configuration files to achieve this capability.
For more information, see "Predefined Server Application Functions and Filters in obj.conf" in Oracle Traffic Director Configuration Files Reference.
For a list of issues that have been fixed in this release, see the My Oracle Support (MOS) note 1988308.1 on the My Oracle Support customer support portal. Also, note the following resolved issues:
Administrators can configure Oracle Traffic Director 11.1.1.x as a 'service' so that the load balancer service is available immediately after an operating system is started or restarted. However, the Linux operating system, by default, assigns a very low number (default is 1024) of File Descriptor resources to the process started as a 'service'. This restriction severely affected Traffic Director's ability to provide acceptable performance.
Oracle Traffic Director 126.96.36.199 addresses this issue by assigning itself higher number of File Descriptor resource at the time of initializing the service to allow serving a large number of concurrent users.
Oracle recommends customers to leverage this load balancing policy if the incoming requests from a same client IP should land at the same content origination server. This load balancing policy is especially useful in the context of TCP Load Balancing.
In Oracle Traffic Director 188.8.131.52, there are a reduced number of packages that are needed for installing Oracle Traffic Director on Oracle Linux 5. For the list of packages, see Oracle Traffic Director Installation Guide.
This section provides information about the known issues for Oracle Traffic Director 184.108.40.206 along with possible workarounds:
Oracle Traffic Director Release 220.127.116.11 mandates JDK 7 u60 as the minimum supported JDK version. Oracle Traffic Director 18.104.22.168 bundles JDK6 for its own administration purposes. Now, Oracle Traffic Director 22.214.171.124 bundles JDK 7.
Review the status of your JDK installation as follows:
If you did not use your own JDK at the time of installing Oracle Traffic Director 126.96.36.199/7, then you do not need to consider JDK version while upgrading to Oracle Traffic Director 188.8.131.52.
If you did use your own JDK while installing Oracle Traffic Director 184.108.40.206/.7, then you will need to now provide JDK version 7 Update 60 or above as the JDK version while upgrading to Oracle Traffic Director 220.127.116.11.
You must also have a correctly set
JAVA_HOME variable. If you have
JAVA_HOME set to JDK 6 in your environment. and run an Oracle Traffic Director CLI command, then you may see the following error:
$ORACLE_HOME/bin/tadm configure-server --user=user1 --instance-home=$INSTANCE_HOME/instance1 --server-user=root Exception in thread "main" java.lang.UnsupportedClassVersionError: com/sun/web/admin/cli/shelladapter/WSadminShell : Unsupported major.minor version 51.0 at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClassCond(ClassLoader.java:631) at java.lang.ClassLoader.defineClass(ClassLoader.java:615) at java.security.SecureClassLoader.defineClass(SecureClassLoader.java:141) at java.net.URLClassLoader.defineClass(URLClassLoader.java:283) at java.net.URLClassLoader.access$000(URLClassLoader.java:58) at java.net.URLClassLoader$1.run(URLClassLoader.java:197) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:190) at java.lang.ClassLoader.loadClass(ClassLoader.java:306) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:301) at java.lang.ClassLoader.loadClass(ClassLoader.java:247) Could not find the main class: com.sun.web.admin.cli.shelladapter.WSadminShell. Program will exit.
Workaround: remove the
JAVA_HOME in your environment.
Oracle Traffic Director Release 18.104.22.168 supports Oracle Linux (OEL) 5.x and 6.x (64-bit).
Oracle Traffic Director uses the
/tmp directory to keep its internal runtime files. These runtime files are largely static and do not significantly consume disk space. If you are using tools such as
tmpwatch to clean up the
/tmp directory, then this tool can affect Oracle Traffic Director's administration capabilities.
Oracle Traffic Director 22.214.171.124 now prefers to store its internal runtime files:
/var/run/otd (if configured as root), or
<instance-root>/net-<config>/logs (when applicable) before leveraging
you can configure another location (preferably a local directory) as the
tmp directory at the time of creating an Admin Server or Admin Node(s) by running the following command:
set-config-prop --user=.. --config=.. ... --temp-path
Alternatively, you can also configure tools such
tmpwatch to exclude Oracle Traffic Director files by running a command within the
/etc/cron.daily/tmpwatch script such as:
tmpwatch -X '/tmp/admin-server-*' -X '/tmp/net-*'
The following error appears after upgrading Oracle Traffic Director to 126.96.36.199.0, and while starting an Oracle Traffic Director instance.
Oracle Traffic Director 188.8.131.52.0 B01/19/2015 12:34 [ERROR:32] [OTD-10251] Error running Init function load-modules: dlopen of /scratch/oamdemo/IDM/BASEDIR/OTD_WG/webgate/iplanet/lib/webgate.so failed (/scratch/oamdemo/IDM/BASEDIR/OTD_WG/webgate/iplanet/lib/webgate.so: undefined symbol: nzos_GetSessionMasterSecret) [ERROR:32] server initialization failed
Workaround: Copy the
libnnz11.so file from
$OTD_WG_HOME/webgate/iplanet/lib folder to the
set-http-listener-prop now supports property,
set-max-requests-per-connection. See "set-http-listener-prop" in Oracle Traffic Director Command Line Reference Guide.
The following log-related executable files will be deprecated.
binlog: A tool for storing binary and un-formatted log data (path:
flexanlg: A tool for analyzing server log data and generating server statistics (path:
The online help for the
install-root as one of its properties. However, this property is not supported.
