Specifying Environment Variables for IPv6

Special considerations apply to using IPv6 with the JDBC server:

• Customers who run multiple TCP/IP stacks must set stack affinity to the appropriate IPv6 stack using the _BPXK_SETIBMOPT_TRANSPORT environment variable. In this instance you must also code the appropriate host name or IP address in the Host parameter of the configuration file as detailed in "Configuring the JDBC Server" topic in this chapter.
• It may be necessary to define a new TCPIP.DATA file which provides a special DNS Resolver configuration for IPv6 hosts and addresses. This file must be specified using the RESOLVER_CONFIG environment variable.

For example, prior to starting the JDBC server, the following statements can be run as part of a user signon profile. Alternatively, they can be included at the beginning of the CA-IDMS Server .idms_wrapper script located in the CA IDMS Server bin subdirectory, in which case they must be run when the JDBC server is started with the supplied shell script.

export JAVA_HOME="your-jvm 1.6 location here"
export _BPXK_SETIBMOPT_TRANSPORT="your-ipv6-proc-name-here"

export RESOLVER_CONFIG="//'your.tcpipv6.data.file.here'"
