Expanding Files

Expanding a file means that CA 2E resolves all of the file’s relations. If the file Refers to another file, that file’s relations are resolved also.CA 2E follows the path of file-to-file relations until all files in the path are expanded. File expansion relates to file locking in the following ways:

• One way to remove an *EXCL lock is to expand the file. For example, enter F, Z, E, or Q against the file on the Edit Database Relations panel.
• If the model is unsynchronized and a *DSNR performs an operation that uses a file,CA 2E expands the file and sets an *EXCL lock on each file in the expansion path momentarily. During the expansion, other developers are prevented from accessing the locked files.

  When the expansion is complete,CA 2E removes the *EXCL locks, sets a *READ lock on the selected file, and performs the requested operation. If CA 2E finds a lock on any file during the expansion, the requested operation is denied.
