Data Mart Backup/HA?

Hello,

Am I correct in believing there is no HA/backup for Data Mart?
And that it runs on its own to complete the ETL processes?
Documentation suggests only Data Sourcer and Stat Servers can run HA in CCA Reporting Solution.

thanks.

Are you talking about the ETL process or the DB called Datamart?

Just install and configure ETL on a second machine and manually start it when you have problems. Even if ETL is down the data remains on ODS until ETL restarts. ETL quickly catches up.

and im correct in thinking both (or 2 etl services cannot run at the same time - both connecting to the same data mart db?

Exactly, it is not allowed to run two or more instances of ETL on same CCA solution, just as a cold-stanby backup.
