quiesed. You may have to manually stop access to some non-HP databases. You can make
STORE wait for you to finish these operations by using the ASK parameter with the ONLINE
option.
You can also now easily store databases with TrueOnline. By default, TurboStore will not allow you
to specify an incomplete TurboImage or ALLBASE/SQL database to be stored. If this is attempted,
a warning will be issued telling you that the dataset(s) will not be stored. To store a database, the
user only needs to specify the root file or DBCon file. Turbostore TrueOnline will figure out which
files are associated with the database and store them all. This behavior may be overridden by
using the PARTIALDB keyword parameter. You will then be able to store only specific datasets
rather than the entire database.
For other file types such as KSAM/XL files, TrueOnline will guarantee that no partial transactions
are included in the copy of the file stored on the tape. For native mode message files, TrueOnline
will follow the necessary steps to successfully imitate closing the file to ensure data integrity,
physical consistency, and recoverability.
Compatibility mode (CM) files, namely Circular (CIR) files, and Relative IO (RIO) files, have internal
buffer structures that cannot be logged by TurboStore. If these files are open for write access
during the sync point, TurboStore will capture their last known state.
User mapped files are still managed the same way as before. If a user-mapped file is left open for
write access across the sync point, then TrueOnline will capture the last known state of the file,
which would either be at the last FOPEN, FCLOSE, or FCONTROL 6. If TrueOnline does not
capture any of these events, the file will be stored in whatever state it was in when TrueOnline
opened the file, which may be inconsistent.
TrueOnline now has the ability to put a copy of a backup's STORE label and STORE directory into
a disk file. This directory information allows RESTORE to more quickly determine where files are
located on the backup, and to prompt users to mount the necessary media. The disc file is created
by STORE and named using the following convention:
store_yyyymmdd_hhmmsstt_pin##_day
The file is located in the HFS directory SYS/HPSTORE/store_dirs/. It is important to note that the
HPSTORE group and store_dirs directory do NOT exist on the system by default. The user MUST
create them, and set up the appropriate security before using the STOREDIR option. STORE will
NOT print a warning if it cannot create the file because the path does not exist.
Another new feature of TrueOnline is the ability to specify where the shadow log files that log
changes to files that are being backed up reside. The LOGVOLSET option allows you to specify
which volume set to use for the log files. This option can be used either with the current ONLINE
feature, or the newer 7x24 TrueOnline feature.
You now have the ability to have the output device for a Store be a disc file. This gives the user the
ability to store the data to disk for those unique situations where this is desired. Since the disk
backup file created is a flat, binary disk file, it can be moved to different systems and then
RESTORE can be used to extract the archived files.
