Logging and Recovery
The Mirror Database
and the user is returned to the MPE/iX prompt. This error usually occurs when another
file with the same name as the RESTART file has been created on the system. Make sure the
file is a RESTART file, and try RESTART again. If the RESTART file cannot be located, go back
to the previous tape, restore the databases which should have their own RESTART file and
log files stored with them, and run DBRECOV,RESTART from that point. The log files
between the previous and the current STOP point are reprocessed, and the roll-forward
process continues with the current log file.
When the correct RESTART file is opened, DBRECOV looks at the file to make sure that the
version numbers are compatible with the version of DBRECOV being run. If the version
numbers do not match, DBRECOV prints the following error message:
RESTART FILE NOT COMPATIBLE WITH THIS VERSION OF DBRECOV
and the user is returned to the MPE/iX prompt. This message means that another version
of DBRECOV is running other than the version that created the current RESTART file. Install
the correct version of TurboIMAGE/XL and run DBRECOV,RESTART again.
If the user logon is not the same as the logon when DBRECOV was suspended, the following
message is printed:
must be logged on as same user and account where DBRECOV was
suspended
Log on using the same user and account names that were used when DBRECOV was
originally suspended, and run DBRECOV again.
When the RESTART file is opened, DBRECOV tries to open all databases identified in the
RESTART file. For each database that cannot be opened,
DBRECOV displays the following
message:
Can't re-open DATABASE basename
RESTART is terminated and the user is returned to the MPE/iX prompt. Make sure the
correct databases are on the system. If the databases are the correct ones, but they still
cannot be opened, use the DBRECOV,ABORT command (discussed in the next section) and
RESTART recovery from the previous STOP point.
When all the databases have been opened, DBRECOV checks to make sure all the databases
in the RESTART file are set for RESTART. When DBRECOV encounters a database not in
RESTART mode, it displays the message:
DATABASE basename IS NOT IN RESTART MODE
RESTART TERMINATED
RESTART is terminated and the user is returned to the MPE/iX prompt. Make sure the
correct databases are loaded on the system. If the databases are the correct ones and
RESTART is still not accepted, use the DBRECOV,ABORT (discussed in the next section)
