Dear OpenSolaris Governing Board members: Please see our HA-Clusters community proposal for a Informix Dynamic Server cluster agent (HA-Informix) for Open High Availability Cluster (OHAC) as per 2.2 of http://www.opensolaris.org/os/community/ogb/policies/project-instantiation.txt
Your support in the instantiation of this project is greatly appreciated. Regards Neil 1) Purpose The purpose of this project is to provide a failover agent for IBM Informix Dynamic Server (IDS) as part of the open-source code base for Solaris Cluster, namely Open High Availability Cluster (OHAC). The aim of this project is to focus on IDS 11, code-named "Cheetah". 2) Sponsors The Community Group sponsoring this project is the HA-Clusters community and voted with 3 +1 votes and 0 -1 vote. 3) Initial Project Team - Thorsten Frueauf - Neil Garthwaite (Contact) - Detlef Ulherr 4) Project Description IDS 11 currently provides several availability features namely: - High Availability Data Replication (HADR) - Enterprise Replication (ER) - Shared Disk Secondary server (SDS) - Remote Standalone Secondary (RSS) Refer to ftp://ftp.software.ibm.com/software/data/informix/ids/Availability_whitepaper.pdf for more details on the above features. Developing an agent for IDS 11 for OHAC simply provides further choice for availability and could be used together with the availability features of IDS 11 or as a solution by itself. 5) Related Projects Currently IBM provides a Sun Cluster failover agent for IDS that was created for SC 3.1 update 2 for Solaris SPARC. IBM provides this agent as free to download but does not offer any formal support for the agent. Specifically the customer is encouraged to modify the agent thereby owning the code. In particular the following text is available when downloading the agent. "IBM Informix HA Agent is sample code that helps customers in setting up IDS (Informix Dynamic Server) in a Sun Cluster environment. The package explains how this sample code works and how it can be used to support IDS in a cluster environment. This package is basic and we expect any customer to modify it based on their requirements." 6) Additional Information The failover agent for IBM Informix Dynamic Server (IDS) that this project proposes will be new code and will not inherit any code from IBM's current agent for IDS. It is our understanding from IBM that they will not develop their agent further and therefore by developing an agent for IDS 11, we will have a clear line of separation between the agent developed by IBM for SC 3.1 update 2 for Solaris SPARC and this project's agent for IDS 11 in OHAC.
