Fw: Multiple journal services, retry

The journal has to be valid before the backup will use the journal, and
a full incremental backup (one that updates the Last Backup Completion
date on the TSM server) must complete while the journal service is running
in order for the journal to be marked as valid.

You can verify the state of the journal with the dbviewb.exe utility
(not shipped with the client, email me directly and I will send to you).

The backup client specifies which journal service to connect to by
setting the JournalPipe client option to match the JournalPipe setting
of the journal service you want to connect to.

There should only be one JournalPipe setting per journal service, and
each journal service must specify a different config file as explained
in my previous note.

Each backup client points to the specific journal service to use by
specifying a JournalPipe client option which corresponds with the
JournalPipe journal config setting of the particular journal service.

This can be done either via the command line (dsmc -JournalPipe=) or
via separate dsm.opt files.

Unfortunately, short of turning on client tracing, no.

One of the items on our development "to do" list is to implement a
"Query Journal" command in the command line client which is capable
of displaying the status of the journal service and file systems
being journaled.

Just our of curiosity, what is your reasoning behind running multiple
journal services ?

Hope this helps and please don't hesitate to post additional questions.

Pete,

I upgraded to 5.3.2.0, disabled the old journal service, created
specific ones for each drive and installed a journal service for each,
per your instructions.  The services are running and there are journal
dbs for each drive, but only the c: journal seems to be showing any
activity, and backups of the other drives don't indicate they are using
the journal.

One part I wasn't sure about was whether I needed to create custom
dsm.opt files for each journal service, or if I could use multiple
journalpipe stanzas.

Is there a way to verify my install config, like what pipe each service
is using?

I'm not sure if the procedure for installing multiple journal services
made it into the client books so I will attempt to explain.

The first step is to create a separate journal config file for each
journal service which will be installed.

Each config file should specify a different JournalPipe value, and
should also specify different drives to journal so that the two services
don't clash with each other.

Note that attempting to have multiple journal services journal the same
drive will cause problems since the different services will attempt to
write to the same journal db unless this is specifically overridden in
the the by specifying different journal dirs in the different config
files.

The next step is to install journal multiple services under different
names.

For example:

dsmcutil install journal /name:"TSM Journal Service 1"
/JBBCONFIGFILE:c:\journalconfig\tsmjbbd1.ini"
dsmcutil install journal /name:"TSM Journal Service 2"
/JBBCONFIGFILE:c:\journalconfig\tsmjbbd2.ini

Backup clients should now be able to connect to the desired journal
service by specifying the JournalPipe client option which corresponds
with the JournalPipe journal service setting.

Hope this helps and please post any additional questions.

We are running server 5.2.2.0 and client 5.3.0.5 Is there a doc with
detailed instructions on either method?

Yes, I've done it (actually I wrote the code to allow doing it).

What version of the client are you running ?

In client versions prior to 5.32, running multiple services really
required installing the two instances of the journal daemon in different
directories because I didn't have the foresight to implement a mechanism
for allowing each journal service to point to a different config file.

In 5.32 a registry setting can added (either manually or via DSMCUTIL)
to point a specific instance of a journal service to a particular config
(tsmjbbd.ini) file.

As you say, the key to running multiple instances of the service is to
specifiy a unique pipe name for the journal service via the JournalPipe
config setting, and to use the corresponding client option to point the
desired journal service.

Hope this helps .....

I didnt see any response, so I'll try again - has anyone successfully
installed multiple journal services on a single windows client?
