Running the Prerequisite Checker

Run the Prerequisite Checker any number of times for any database instances on the production server, and review the results.html in your browser.

Before you begin

Log on to the production server that is to be supported by IBM® Storage Protect Snapshot, with the root user ID. Check the following requirements:

The database is activated. Verify that the database is activated.
The default environment of the instance owner must contain all the environment settings necessary for interaction with the database.
The instance owner must have the necessary access rights.

Log on with the root user ID.
Change to the checker_path directory where the Prerequisite Checker was installed.
Run the fcmprereqchecker.sh script as follows:
```
./fcmprereqchecker.sh -u <instance_owner> -s <storage_management_IP_address> 
-p <storage_management_port> [-o <output_path>] [-d <database_name>]
```
Where,
- instance_user is the name of the instance owner.
- storage_management_IP_address is the name or IP address of the storage subsystem that contains the database files.
- storage_management_port is the management port of the storage subsystem that contains the database files.
- output_path is used to specify a fully qualified directory where all output files and information are written. The default output path is checker_path/logs.
- database_name is used to specify the name or alias of the database to be checked.
For DB2®, the database_name must be specified when multiple databases are in the instance that is owned by dbusername.
