This section gives some abbreviated scenarios for when you are thinking of installing WebSphere® MQ Version 6.0.
The following table provides an overview of what will occur for the different TCP/IP stacks (IPv4 only, IPv6 only and dual IPv4 and IPv6 stacks) and given the settings for CONNAME and LOCLADDR the expected connection result.
Stack Type | CONNAME setting | LOCLADDR setting | Connection result |
---|---|---|---|
IPv4 only stack | IPv4 address | Channel binds to IPv4 stack | |
IPv6 address | Channel fails to resolve CONNAME | ||
Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv4 stack | ||
IPv4 address | IPv4 address | Channel binds to IPv4 stack | |
IPv6 address | IPv4 address | Channel fails to resolve CONNAME | |
Host name resolves to both IPv4 and IPv6 addresses | IPv4 address | Channel binds to IPv4 stack | |
Any address | IPv6 address | Channel fails to resolve LOCLADDR | |
IPv4 address | Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv4 stack | |
IPv6 address | Host name resolves to both IPv4 and IPv6 addresses | Channel fails to resolve CONNAME | |
Host name resolves to both IPv4 and IPv6 addresses | Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv4 stack | |
Dual IPv4 and IPv6 stack | IPv4 address | Channel binds to IPv4 stack | |
IPv6 address | Channel binds to IPv6 stack | ||
Host name resolves to both IPv4 and IPv6 addresses | Channel binds to stack determined by IPADDRV | ||
IPv4 address | IPv4 address | Channel binds to IPv4 stack | |
IPv6 address | IPv4 address | Channel fails to resolve CONNAME | |
Host name resolves to both IPv4 and IPv6 addresses | IPv4 address | Channel binds to IPv4 stack | |
IPv4 address | IPv6 address | Maps an IPv4 CONNAME to an IPv4 mapped IPv6 address. IPv6 implementations that do not support IPv4 mapped IPv6 addressing fail to resolve CONNAME | |
IPv6 address | IPv6 address | Channel binds to IPv6 stack | |
Host name resolves to both IPv4 and IPv6 addresses | IPv6 address | Channel binds to IPv6 stack | |
IPv4 address | Host name resolves to both IPv4 and IPv6 addresses | Maps an IPv4 CONNAME to an IPv4 mapped IPv6 address. IPv6 implementations that do not support IPv4 mapped IPv6 addressing fail to resolve CONNAME | |
IPv6 address | Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv6 stack | |
Host name resolves to both IPv4 and IPv6 addresses | Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv6 stack | |
IPv6 only stack | IPv4 address | Maps an IPv4 CONNAME to an IPv4 mapped IPv6 address. IPv6 implementations that do not support IPv4 mapped IPv6 addressing fail to resolve CONNAME | |
IPv6 address | Channel binds to IPv6 stack | ||
Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv6 stack | ||
Any address | IPv4 address | Channel fails to resolve LOCLADDR | |
IPv4 address | IPv6 address | Maps an IPv4 CONNAME to an IPv4 mapped IPv6 address. IPv6 implementations that do not support IPv4 mapped IPv6 addressing fail to resolve CONNAME | |
IPv6 address | IPv6 address | Channel binds to IPv6 stack | |
Host name resolves to both IPv4 and IPv6 addresses | IPv6 address | Channel binds to IPv6 stack | |
IPv4 address | Host name resolves to both IPv4 and IPv6 addresses | Maps an IPv4 CONNAME to an IPv4 mapped IPv6 address. IPv6 implementations that do not support IPv4 mapped IPv6 addressing fail to resolve CONNAME | |
IPv6 address | Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv6 stack | |
Host name resolves to both IPv4 and IPv6 addresses | Host name resolves to both IPv4 and IPv6 addresses | Channel binds to IPv6 stack |
The following table gives a number of abbreviated scenarios based on the configuration of the installed queue managers and the IP configuration they are running on. The list is not intended to be exhaustive, but to give a number of examples of what to expect based on the configurations shown.
Abbreviation1 | Meaning1 |
---|---|
v53 | a WebSphere MQ Version 5.3 or earlier queue manager |
v6 | WebSphere MQ Version 6.0 queue manager |
IPv4 | a system using an IPv4 only stack |
IPv6 | a system using an IPv6 only stack |
Dual | a system using both an IPv4 and an IPv6 stack |
IPv4DNS | DNS returns an IPv4 address only for hostname of system holding the responding queue manager |
IPv6DNS | DNS returns an IPv6 address only for hostname of system holding the responding queue manager |
DualDNS | DNS returns an IPv4 and IPv6 address for hostname of system the holding responding queue manager |
LOCLADDR4 | The LOCLADDR parameter is set to IPv4 addressing |
LOCLADDR6 | The LOCLADDR parameter is set to IPv6 addressing |
IPADDR4 | IPADDRV is set to IPv4 addressing |
IPADDR6 | IPADDRV is set to IPv6 addressing |
