DB2 Server for VM: System Administration

CMS Restrictions

The CMS RESERVE command creates a CMS-like file for each database minidisk. If you were to issue a CMS LISTFILE command for the database minidisks, you would, in fact, see that a file resides on each minidisk. These files, however, are not the same as regular CMS files.

Attention: Never use the following CMS file manipulation commands or macros on the database files, because they can render the database useless:

• ACCESS (with the ERASE option)
• ERASE
• EXECIO
• FORMAT (the minidisk after the database is created)
• MOVEFILE (to write to the file)
• RESERVE (the minidisk after the database is created)
• READCARD
• DISK LOAD
• RECEIVE (with the REPLACE option)
• FSERASE
• FSWRITE.
