The ssatune utility performs the following tasks:

Analyzes available system resources and calculates Data Vault configuration parameters based on CPU and RAM.
Analyzes meta query response time and sets the optimum query execution mode for the metadata layer.
Tunes the metadata server configuration.
Analyzes the Data Vault temporary storage requirement based on current archive volume and returns a recommendation.
Refreshes metadata catalog indexes to optimize internal query response time.
Performs metadata database garbage collection to improve overall metadata layer performance.
On UNIX systems, operates in high availability mode, which minimizes the Data Vault system down time in the event of an abnormal termination or unexpected shutdown.
Evaluates I/O response time.
Updates Data Vault configuration files and performs a backup of the existing configuration.
Generates a report about current system resources and recommended configuration changes.

The ssatune utility operates in one of the following two modes:

Evaluation and report only
Evaluation and apply changes

The ssatune utility uses the following syntax:

ssatune [ <flags> ]
[-h (displays the help screen)]
[-m{0,1} (report only vs. update configuration)]
[-t <temporary file directory>]

When the ssatune utility is finished, it generates a shell script named

fasd.sh

in the Data Vault root folder. The utility also configures the

ssa.ini

file settings in the STARTER and META sections to enable Data Vault process controls through the generated script. After ssatune generates the script, you can use the script to manage all Data Vault processes.

To start the Data Vault system, run the following command:

The following message appears: "Starting-> IDV components"

To stop the Data Vault system, run the following command:

The following message appears: "Stopping IDV components"
