Creating Scheduled Services in Oracle Solaris [44705]
By Dan Krasinski

Dan Krasinski blogs, "In the previous post, we introduced the idea of scheduled services in Oracle Solaris as an alternative to cronjobs. Here, we'll do a deep dive into the scheduling model and create a basic service.

Scheduled Services and cronjobs have fundamentally different scheduling models. The model that cron(1M) uses is based on pattern matching. Each line in a crontab specifies a set of conditions specifying when a job should run. Each minute, the cron daemon wakes up and checks each job to see if those criteria match the current moment. If they do, then cron executes the job..."

Doug Schwabauer writes, "Enterprise Manager Ops Center has a rich feature set for Oracle VM Server for SPARC (LDOMs) technology. You can provision Control Domains, service domains, LDOM guests, control the size and properties of the guests, add networks and storage to guests, create Server Pools, etc. The foundation for many of these features is called a Storage Library. In Ops Center, a Storage Library can be Fiber Channel based, iSCSI based, or NAS based.

For FC and iSCSI-based LUNs, Ops Center only recognizes LUNS that are presented to the Solaris Host via MPxIO, the built in multipathing software for Solaris. LUNs that are presented via other MP software, such as Symantec DMP, EMC Power Path, etc., are not recognized.

Sometimes users do not have the option to use MPxIO, or may choose to not use MPxIO for other reasons, such as use cases where SCSI3 Persistent Reservations (SCSI3 PR) is required..."
