Dataguard alike using bash and cron

Oracle EE is quite more expensive than SE, however sometimes you need a standby replica “just in case”.

This is how you get a standby replica on a different server, without breaking any Oracle licensing rules:

1) the following script has to be on both servers. It calls itself on remote.
2) set up a cronjob to launch the script on the primary server.
3) Check the log.

I must say that this script needs some big cleaning and ordering, but it works.
