Appendix D. Moving from single to multi-node environment

This appendix describes the steps needed to move from a single-node runtime implementation to a multi-node remote database runtime environment after the migration took place.

Most of the steps described in this appendix are based on what we have already documented in previous chapters.

This appendix is organized in the following sections:

Single-node environment

Installing and configuring the database node

Moving the database

Connecting to the remote database
