Redundant environment of Chordiant setup

SA-22600

Summary



Query on creating a redundant environment of Chordiant setup. Currently user has one machine that manage critical campaigns.

The schedules of these campaigns are at risk of missing in case the machine was down and no backup environment exist.

So user requires support to build parallel environment in any of available setup feasible (Active/Active, Active/Passive) to back up their setup and maintain their campaigns.


Error Messages



Not Applicable.


Steps to Reproduce



Not Applicable.


Root Cause



Query related to Redundant environment.

Resolution



Redundant environment can be created by installing Chordiant Marketing Director (CMD) binaries on machine identified for parallel environment.

This involves copying or nstalling CMD binaries on given machine, configuring RPC and Vantage.init file according to new machine.

During Vantage.init file configuration, below mentioned parameters has to be configured according to CMD schema that needs to be used (backup CMD schema or existing CMD schema):
  • VenvVantageAccount
  • VenvDbase
  • VenvDbaseHome
  • VenvDbaseURL
  • VenvNLSLang
  • VenvRole

CMD services on parallel environment has to be started as and when required.

Refer “Marketing_Director_Initialization_Variables.pdf”, “Marketing_Director_Installation_UNIX_Oracle.pdf” and “Marketing_Director_Ongoing_Tasks_UNIX.pdf” documents on CMD CD for detailed information regarding installation, Vantage.init file parameters and CMD services.

Following are the information related to hardware configuration query.

Based on our experience and knowledge of our customers’ environment, here are some useful tips:
  •  MD processes are light weight; about 80% of the “work” happens on the database servers
  • The general rule is that 1 CPU core is enough for a development environment and 2 CPU for production to start with
  • The RAM size is usually calculated as no. of CPU X 2 which means 2 GB RAM for development and 4 GB RAM for production
  •  For the database server, the specification would be double or sometimes thrice of the MD server. So it would be 4-6 CPU/8-12 GB for a production database server
  •  Using this configuration, you can easily run 10-15 campaigns and additionally around 15 segments in parallel. Keep in mind that it’s the database server that is taking majority of the load, not the MD server.
 These are the general specifications that you may be considered to start with. Depending on testing phase results and business requirement, increase the specs by another 20-25% might also be considered
