Guidelines for using quiesce database

The simplest way to use quiesce database is to make a full copy of an entire installation, which ensures that system mappings are consistent.

These mappings are carried to the secondary installation when the system databases that contain them are physically copied as part of quiesce database hold’s set of databases. These mappings are fulfilled when all user databases in the source installation are copied as part of the same set. quiesce database allows for eight database names during a single operation. If a source installation has more than eight databases, you can issue multiple instances of quiesce database hold to create multiple concurrent quiescent states for multiple sets of databases.

To create a new source installation, you can use almost identical scripts to create both the primary and secondary installations. The script for the secondary installation might vary in the physical device names passed to the disk init command. This approach requires that updates to system devices on the primary server be reflected by identical changes to the secondary server. For example, if you perform an alter database command on the primary server, you must also perform the same command on the secondary server using identical parameters. This approach requires that the database devices be supported by a volume manager, which can present to both the primary and secondary servers the same physical device names for devices that are physically distinct and separate.

Your site may develop its own procedures for making external copies of database devices. However, recommends the following:
