This task describes how to set IMAGE/SQL utility file equations for two files:
ATCINFO and ATCLOG.
Setting a File Equation for ATCLOG |
 |
A file equation for ATCLOG can be issued before beginning an IMAGE/SQL utility session.
For example:
:FILE ATCLOG = SALELOG1; SAVE
:
|
In the above example, when the logging option is on, IMAGE/SQL utility commands are logged
to the permanent file SALELOG1.
A file equation for ATCLOG can also be set or reset from within the IMAGE/SQL utility.
For example:
>>:FILE ATCLOG = SALELOG2; SAVE
>>
|
Now when the logging option is on, IMAGE/SQL utility commands are logged to the
permanent file SALELOG2.
Task Reference
The ATCINFO file 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. The default name of the ATCINFO file is
DBEnvironmentNameCR.
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.
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 is a temporary unnumbered ASCII file to which
all IMAGE/SQL utility commands are written when the IMAGE/SQL utility 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 IMAGE/SQL utility 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 want 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/iX 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.
