Yes, this info is near the end of
http://www.backupcentral.com/foms/netbackup-serve/cache/207.html and yes,
the main NetBackup registry settings are located at HKEY_LOCAL_MACHINE -
Software - Veritas - Netbackup - CurrentVersion - Config.

Well,
Did you take a look really at this files before saying that ?
In the first url : 207 if you look at the end of this document (maybe not
all of them but...).
I copy you this keys but...
More OTM Registry info from Veritas Support:
OTM Settings
Open Transaction Manager Registry Settings
These are located in HKEY_LOCAL_MACHINE - Software - Veritas - Netbackup -
CurrentVersion - Config:
· OTM_USE (if this is not present the default setting is YES and Open
Transaction Manager is enabled) · Applicable Settings: "NO" = disabled "YES"
= enabled
· OTM_Cache_File · If this is not present the cache file defaults to c:\temp
If this is specified it must be specified down with the full path down to
the FILENAME. Data type of Reg_SZ (eg. e:\temp\otm.tmp where otm.tmp is a 0
byte file)
· OTM_Cache_Size_Init · NetBackup Properties Specifies the initial size of
the cache file (in megabytes). If a specific value is not set, NetBackup
sets it to 10 megabytes. If the value is set to 0, NetBackup sets it to 10%
of the used disk space. (Patch 326 or higher should be used for the Initial
Cache Size = 0 setting)
· OTM_Cache_Size_Max · Specifies the maximum cache size (in megabytes) of
the cache file. If the cache file reaches this size and more cache is
required, Open Transaction Manager is turned off and the backup continues.
However, relationships between the backed up files can be lost because the
snapshot is not used. The default maximum cache size is 50 megabytes. This
can also be set this to 0 and NetBackup will dynamically allocate space.
· OTM_Current · Applicable settings are: "YES" = Individual Drive Snapshots
Specifies that Open Transaction Manager take a snapshot of each drive and
back it up before proceeding to the next drive. For example, assume that
drives C and D are being backed up. Here, Open Transaction Manager: 1. Takes
a snapshot of drive C, backs it up, and discards the snapshot. 2. Takes a
snapshot of drive D, backs it up, and discards the snapshot. Open
Transaction Manager is enabled on only one drive at a time, depending on
which one is being backed up. This mode is useful when it is not necessary
to maintain relationships between files on the different drives.
"NO" = Global Drive Snapshots: Specifies that Open Transaction Manager take
a snapshot that includes all drives that are part of the backup and then
back up the drives. For example, assume that drives C and D are being backed
up. Here, Open Transaction Manager: 1. Takes a snapshot of C and D. 2. Backs
up C and then backs up D. 3. Discards the snapshot. Open Transaction Manager
remains enabled on both the C and the D drives for the entire duration of
the backup. This mode is useful when it is necessary to maintain the
relationships between files on the different drives.
"ALL_AVAILABLE" Specifies that Open Transaction Manager be enabled on all
drives, regardless of which ones are being backed up. If backing up clients
in a class that is using "Allow Multiple Data Streams", this setting ensures
that all the backups can use Open Transaction Manager. For example, assume
the following: * A client has four drives: C, D, E, and F. * The class file
list contains directives that split the client backup into two streams, each
of which is an independent backup. Drives C and D are in one backup and
drives E and F are in the other backup. * The server attempts to start both
backups at the same time. If Individual drive snapshots or Global drive
snapshots are selected, the following occurs: 1. The drive C and D backup
starts. 2. NetBackup enables Open Transaction Manager for drives C and D. 3.
The drive E and F backup starts. However, NetBackup cannot enable open
transaction management for drives E and F. When open transaction management
is active, another enable attempt succeeds only if the set of drives are the
same as the active set. In this example, the sets are different. 4. The
drive E and F backup continues, but without Open Transaction Manager. If
"Use all available drives" is selected, the following occurs: 1. The drive C
and D backup starts. 2. NetBackup enables Open Transaction Manager for all
drives (even though E and F are not part of the current backup). 3. The
drive E and F backup starts. 4. NetBackup enables transaction management for
all drives. This attempt succeeds because the set of drives is the same as
the one that is already using Open Transaction Manager. 5. Both backups use
Open Transaction Manager.
· OTM_Exclude: · The Exclude tab allows you to create and modify the exclude
lists on Microsoft Windows clients. An exclude
list names files and folders that you want to exclude from automatic
backups. The Files/Directories box shows the lists for clients that were
selected when the dialog box was opend. If multiple clients were selected, a
scroll bar is present at the bottom of the list box. Move the bar to display
the list for the desired client (only one list at a time can be modified). *
To add a file or directory to the list that is being displayed, click Add
List Item. * To modify a file or directory entry, select it in the list,
click Edit List Item, and make the change. * To Delete a file or directory
entry, select it in the list and click the Delete key.
· OTM_Quiescent_Timeout: · Busy File Timeout Specifies the duration (in
seconds) of the quiet period that must occur so the snap can be taken. The
default is 60 seconds. This a 60 second time period in which the
quiescent_wait must occur.
· OTM_Quiescent_Wait: · Busy File Wait Specifies how many seconds to wait
for a quiet period to occur. If this time expires, the backup proceeds but
without backing up the file. The quiet period is a period of time during
which no writes are being performed on the drives or volumes to be backed
up. The default is 5 seconds.
· OTM_Error_Control (Controls how OTM reacts when it encounters an error.)
The default is abort. The applicable values are listed below. Data type is
Reg_Dword:
0 = Abort on Error 1 = Disable OTM 2 = Retry OTM
