The main tool for setting up cron jobs is the crontab command, though this is not available on every Unix variant. Typically under Solaris or Linux one would create a new crontab or edit an existing one, using the command; crontab -e
Use the ls -l command to verify the contents of the/var/spool/cron/crontabs file.

shadowd is a daemon that provides background worker threads to migrate data for a shadow migration. A shadow migration gradually moves data from a source file system into a new "shadow" file system. Users can access and change their data within the shadow file system while migration is occurring.
The shadowd service is managed by the service management facility, smf(5).
Administrative actions on this service, such as enabling, disabling, or requesting restart, can be performed using svcadm(1M). The service's status can be queried using the svcs(1) command.
The svccfg(1M) command can be used to manage the following parameter related to shadowd:
config_params/shadow_threads
Note: Oracle Solaris 11: In this release, you can migrate data from an old file system to a new file system while simultaneously allowing access and modification of the new file system during the migration process.
Setting the shadow property on a new ZFS file system triggers the migration of the older data. The shadow property can be set to migrate data from the local system or a remote system with either of the following values:
file:///path
nfs://host:path

A: Conditional and system locations can be manually activated,which means that the location remains active until explicitly disabled.
D: A location comprises certain elements of a network configuration,for example a name service and firewall settings,that are applied together,when required. You can create multiple locations for various uses. For example,one location can be used when you are connected at the office by using the company intranet. Another location can be used at home when you are connected to the public Internet by using a wireless access point. Locations can be activated manually or automatically,according to environmental conditions,such as the IP address that is obtained by a network connection.

The coreadm command is used to specify the name and location of core files produced by abnormally-terminating processes.
