SAS Micro Analytic Service
uses GemFire cache to persist information about modules deployed in
it. Like any other persistent storage of content, this store must
be backed up regularly, in accordance your organizational policies.
In the case of a hardware failure, the content of the cache can be
restored from the last good backup to minimize downtime. If backups
are not available, all modules have to be redeployed.
GemFire provides an
online backup facility where all nodes of the cluster must be operational
during the backup process. To restore from a backup, all nodes of
the cluster must be shut down.
This chapter describes
the backup and restore procedure as it applies to SAS Micro Analytic
Service.
The GemFire persistence
folder for a SAS Micro Analytic Service system is found in SAS-Configuration-Directory/LevN/Web/WebAppServer/SASServer13_n/logs,
where LevN is the SAS configuration
level directory, and 13_n denotes
the application server processes. This is where GemFire holds files
that contain an image of the GemFire shared cache.
