Less known Solaris Features: Remote Mirror with AVS - Part 5: Replication Groups

Monday, March 31. 2008

A new scenario: Okay, the filesystem gets replicated now. Let´s assume that we use /dev/rdsk/c1d0s1 for a database. The filesystem and the database partition are used from the same application and it´s important, that the metadata in the database an the binary objects are in sync even when you switched over to the remote site, albeit it´s acceptable to lose the last few transactions, as both sites are 1000km away from each other and synchronous replication is not an option.

Less known Solaris Features: Remote Mirror with AVS - Part 1: Introduction

Sunday, March 30. 2008

Solaris was designed with commercial customers in mind. Thus this operating environment has some capabilities that are somewhat useless for the soho user, but absolutly essential for enterprise users. One of this capabilities is remote replication of disk volumes. Imagine the following situation. You have a database and a filesystem for a central application of your company. The filesystem stores binary objects (for example images or something like that). The application is so important for your company, that you plan to build a replicated site. And now your problems start.
