Publishing service artifacts on UDDI
Although Oracle provides a clear OSR installation guide, we would like to advise you to
be careful with the node installation sequence for security reasons. Naturally, all central-
ized assets concentrated in the Registry are protected by security policies and ACLs. We
recommend LDAP for the storage of user accounts, but trust the relations between regis-
tries in the propagation chain, maintained by digital security certificates. Therefore, we
advise you to start from the end. The digital security certificate of the Discovery Registry
is needed when installing the Publication Registry.
Another highly important SOA pattern must be strictly observed here due to the critical
nature of the Registry and its position as the single point of failure: redundant implement-
ation. In the WLS-based topology, we choose from the very beginning; it's attained by
means of a WebLogic Cluster. The Cluster operation is achieved by running multiple re-
gistries and combining their functionalities with a load balancer (proxy). The configura-
tion of this infrastructure is common for WLS and well documented in the HA section of
the OSR installation guide.
