CRUISE Concepts

CRUISE is based on a parameter table, which contains all the necessary information required to process a CRUISE function. A parameter table must be created, named, set up, and maintained by the database administrator. Parameter table maintenance allows the setup of default values and prepares for application use. A CRUISE function processes a defined parameter table when you use a ZFCRU command.

Help is available by using the ZFCRU HELP command.

CRUISE Benefits

CRUISE is a versatile and easy to use method of managing your database. Based on file information stored in the TPFDF database definition (DBDEF), CRUISE is a process of recovering and validating data, controlling pool space, and creating statistics. The following are some benefits of using CRUISE:

CRUISE Terminology

When you use CRUISE, it is important to understand the following terms:

CRUISE function
The process that performs the steps specified by a parameter table. The following are CRUISE functions:

CRUISE commands
The ZFCRU commands that perform CRUISE functions.

Parameter table
The source of parameter values that define how a CRUISE function is processed.

CRUISE States

The following list describes the different parameter table states of the capture/restore utility, information and statistics environment (CRUISE) as displayed by the ZFCRU DISPLAY command with the ALL parameter.

Active
A parameter table that is verified after the initial ZFCRU START command is entered.

Running
A parameter table that is processing a specified CRUISE function after a second ZFCRU START command is entered.
Note:
A CRUISE function in running state is in use.

Paused
A parameter table in running state that has paused.

Stopped
A parameter table processing a CRUISE function that is suspended when you use the ZFCRU STOP command.
