Mounting a Database

Use the mount command to attach the database to the destination or secondary SAP ASE.

The mount command decodes the information in the manifest file and makes the set of databases available online. All the required supporting activities are executed, including adding database devices, if necessary, and activating them, creating the catalog entries for the new databases, recovering them, and putting them online.

The mount command limits the number of databases to eight in a single command.

See mount in the Reference Manual: Commands.

Note: mount allows you to identify more than one database for a move operation. However, if a device is used for more than one database, then all of the databases must be moved in one operation. You specify the set of databases being transported. The devices used by these databases cannot be shared with any extraneous database besides the ones specified in the command.
You can use the mount command in different ways:
When you mount databases onto an SAP ASE:
To create a mountable version of a database:
  1. Use the quiesce database command with the manifest clause and quiesce the database. This command creates a manifest file describing the database.

  2. Use the mount command with listonly to display the list of devices to be copied.

  3. Use external copy utilities, such as cp, dd, split mirror, and so on, to copy the database devices to another SAP ASE.The copy of the devices and the manifest file is a mountable copy of the database.
