Release Notes
11g Release 1 (11.1.1.7.0)
E21039-03
August 2013
This document contains information about the known issues for Oracle Traffic Director 11.1.1.7.0. For information about the new features in this release of Oracle Traffic Director, see "What's New in this Release" in the Oracle Traffic Director Administrator's Guide.
This section provides information about the known issues for Oracle Traffic Director 11.1.1.7.0 along with possible workarounds:
This section provides information about the known issues for Oracle Traffic Director 11.1.1.7.0 installed on Oracle Linux on Exalogic.
The server.xml schema enforces a limit on the maximum number of connections that can be made to a single origin server. This limit is 20480.
If Oracle Traffic Director instances are reconfigured before running the snmpwalk command, snmpagt does not initialize correctly and it crashes.
This is an initialization issue with the Oracle Traffic Director snmp agent. The agent can be initialized by performing the following steps:
Start the instance server.
Start snmpagt.
Run the following snmp command:
snmpwalk -v2c -c public <host:11161> 1.3.6.1.4.1
The snmpwalk command will force snmpagt to initialize correctly.
Note:
Make sure to execute the snmpwalk command once whenever snmpagt is started or restarted.
If you use the --node-host option while configuring an administration node and specify the host name in uppercase, then the following error might be displayed for that particular node when performing lifecycle operations such as starting, stopping, reconfiguring Oracle Traffic Director instances or deploying Oracle Traffic Director configuration changes:
OTD-63763, Configuration <config-name> has not been deployed to node <node-name>.
While configuring an administration node, specify the value for --node-host option in lowercase.
After the primary and backup failover nodes have been toggled using the administration console, the nodes are correctly listed as toggled. However, a message in the Console Messages pane will incorrectly indicate that the nodes were not toggled.
JSESSIONID is the value that is displayed as the default value for the sticky cookie property for routes in the administration console and CLI. This value is wrong, and the correct default value for sticky cookie is asterisk (*).
In the Oracle Traffic Director administration console, while creating failover groups using the New Failover Group wizard, it is not possible to configure failover groups based on network interface aliases.
Perform the following steps to configure failover groups using network interface aliases. For example, to configure the VIP on the bond0:3 interface alias:
Create a failover group on the bond0 interface. For information about creating a failover group, see "Creating Failover Groups" in the Oracle Traffic Director Administrator's Guide.
Edit the keepalived.conf file, located at INSTANCE_HOME/net-config_name/config, and add the alias name as a label for the IP address. In the example below, the virtual_ipaddress option is edited to include label bond0:3:
Before editing:
vrrp_instance otd-vrrp-router-1 {
priority 225
interface bond0
virtual_ipaddress {
10.244.64.187/24
}
virtual_router_id 253
After editing:
vrrp_instance otd-vrrp-router-1 {
priority 225
interface bond0
virtual_ipaddress {
10.244.64.187/24 label bond0:3
}
virtual_router_id 253
After editing the keepalived.conf file, start /stop the instance for the changes to take effect.
Note:
When creating a failover group, if the administration node process is running as non-root on the node where the instances are located, then you must run start-failover on those nodes as a root user. This is to manually start the failover. If this command is not executed, failover will not start and there will be no high availability.
Services are enabled/disabled per node, and there is no way to enable/disable services on specific instances running on a node.
Use the chkconfig command to prevent a service from starting after a boot/reboot. For example, to disable service for specific instances on a node, run the following command:
chkconfig <service-instance-name> off
When creating a failover group using the administration console or the CLI, if the administration nodes that you select for high availability do not have Oracle Traffic Director instances available on them, then the following error message will be displayed:
Error occurred in creating the failover group with virtual IP <ip_address>. java.lang.NoSuchMethodException: com.sun.web.admin.mbeans.ConfigurationMBean.createInstance(com.sun.web.admin.configlib.Configuration, com.sun.web.admin.configlib.DeployedConfiguration, java.lang.Boolean, java.lang.Boolean, java.util.List, com.sun.web.admin.exceptions.MultiNodeException)
Before creating the failover group, ensure that the primary and backup instances are available. For more information about creating instances, see "Creating Oracle Traffic Director Instances" in the Oracle Traffic Director Administrator's Guide.
This section provides information about the known issues for Oracle Traffic Director 11.1.1.7.0 installed on Oracle Solaris on Exalogic, and Oracle SuperCluster.
Auto detection of network interface fails when creating a failover group using the tadm command in Solaris SuperCluster. The same command succeeds when network interface is specified.
Oracle Traffic Director cannot be configured to provide high availability on IP over IB. Currently, on Solaris, Oracle Traffic Director supports high availability only on Ethernet over IB on a global zone.
