Setting Turbo CONNECT File Equations: Task 11
This task describes how to set ATCUtil file equations for two files:
ATCINFO and ATCLOG.
Performing the Task
Setting a File Equation for ATCINFO
An ATCINFO file equation can only be set before the file is created
(before any TurboIMAGE/XL databases are attached to the DBEnvironment)
(see Task Reference). Only the file name can be specified. Other
parameters of the FILE command will not be valid at attach time.
For example:
_____________________________________
| |
| :FILE ATCINFO = PARTSATC |
| : |
_____________________________________
Setting a File Equation for ATCLOG
A file equation for ATCLOG can be issued before beginning an ATCUtil
session.
For example:
_____________________________________
| |
| :FILE ATCLOG = SALELOG1; SAVE |
| : |
_____________________________________
In the above example, when the logging option is on, ATCUtil commands are
logged to the permanent file, SALELOG1.
A file equation for ATCLOG can also be set or reset from within ATCUtil.
For example:
_______________________________________
| |
| >> :FILE ATCLOG = SALELOG2; SAVE|
| >> |
_______________________________________
Now when the logging option is on, ATCUtil commands are logged to the
permanent file, SALELOG2 (see Task Reference).
Task Reference
ATCINFO Reference.
* ATCINFO is a permanent privileged file containing mapping information
about data set and field names, data types, and user security. Its
formal file designator is ATCINFO.
* One ATCINFO file exists for each DBEnvironment. It is created in the
same group and account as the DBEnvironment and is considered part of
the DBEnvironment.
* If several DBEnvironments exist in the same group and account, the
first attach may use the default file name, ATCINFO. However, a file
equation must be issued for ATCINFO before the first attach to each
subsequent DBEnvironment or an error message results.
* The ATCINFO file equation can only be used to specify a different
file name. It cannot be used to override other ATCINFO file
characteristics.
ATCLOG Reference.
* ATCLOG is a temporary unnumbered ASCII file to which all ATCUtil
commands are written when ATCUtil logging is on. If this file does
not already exist, it is created. If it already exists as a
temporary or permanent file, log file records are appended to it.
Its formal file designator is ATCLOG.
* When an ATCUtil session begins, logging is on and the ATCLOG file is
created (if it does not already exist) and opened in the user's logon
group and account. By default, it is a temporary file named ATCLOG,
but you may wish to set a file equation for this file.
* If you want to save the temporary file, either specify SAVE as a part
of the FILE command, or save the file before ending your current MPE
XL session.
* The FILE command can be used to override default ATCLOG file
attributes, such as size and file domain. However, the log file must
remain an unnumbered ASCII file.
