Description
The START and STOP DATABASE commands are used primarily in conjunction with setting up and accessing Read Only Shared (ROSHARE) databases. A START DATABASE command must be issued after a STOP DATABASE command in order to make the tables in a ROSHARE database accessible to other locations.
The START DATABASE command is permanent until a STOP DATABASE command is executed, even if the user logs out or the Server is brought down. When a START DATABASE command is issued to start a database in RW mode, a value of "W" is placed in the IBMREQ column of the SYSIBM.SYSDATABASE table.
The ACCESS clause introduces either the default read-write (RW) option or the read-only (RO) option. ACCESS (RO) must be added to the START DATABASE command to start a ROSHARE database in read-only mode. Read-only mode allows users at other locations to directly read (select) data in the ROSHARE database.
ROSHARE database owners must issue a START DATABASE command (RW option default) before attempting to insert, update or delete records in the database.
