Defining a Database Copy
To create a volume copy of an existing database volume, first

or click Cancel to end the task.
Copy Volume Name
Enter the file name of the volume you want to assign as a
database volume copy.
- For VSAM linear data sets, specify a standard VSAM
cluster name. A VSAM cluster name consists of one or more
qualifiers, which are delimited by periods.
- The length of each qualifier is from 1 to 8 alphanumeric
characters.
- The maximum length of the cluster name is 42 characters.
Example: ADSM.BFS.POOL2.VOLA
- Database volume copies increase the availability of the
database and provide safeguard against media failure.
- You can have as many as two volume copies of an existing
database volume. After each database volume copy is
defined, the server attempts to synchronize the volume
copy with the database.
