Copies

A copy of a Database (DB) can be made by using the RCFCOPY command. For example the following command: will create a copy of the existing DB PIPEA/PIPEA in the new DB ADMIN/TEST.

RCFCOPY PIPEA/PIPEA ADMIN/TEST

The key features of copies are:

• All copies of DBs have the same DB Number. This may be seen by using the LIST FILES command. For example:

  MASTER/DES  DESI  NUMBER 14  FILE NAME /%DRA000%/dra013 UPDATE

  PIPEA/PIPEA DESI  NUMBER  2  FILE NAME /%DRA000%/dra001 UPDATE

  ADMIN/TEST  DESI  NUMBER  2  FILE NAME /%DRA000%/dra003 UPDATE

  USER/DRAFT  PADD  NUMBER  5  FILE NAME /%DRA000%/dra004 UPDATE

• There is no implied direction of copying. Thus, in the previous example, PIPEA/PIPEA and ADMIN/TEST are each a copy of the other.

• The contents of all copies are identical with respect to both data and structure.

• Any given element has the same reference number in each copy.

• A DB may have any number of copies, but copies may not exist in the same MDB.
