Installing a three server Data Repository (DR) cluster. When installing on multiple nodes it is very similar to installing on a single node.
a) Review the Installation Requirements and Considerations:
b) To ensure that your Data Repository installation is successful, complete the requirements before you install Data Repository:
c) Install the DR:
Note you only run the ./installDR.bin on one node, this extracts the installer files used later.
Note step 7, when you are editing the drinstall.properties, you put all three node names in the DbHostNames entry:
"DbHostNames=The comma-delimited list of hostnames for Data Repository
When you run the dr_validate.sh and dr_install.sh script later, it uses the values in drinstall.properties to identify and validate./install on those servers.
