DB2 - is it possible to create database on remote node?

Hi.

Our installer is run shell scripts with following commands:

DB2 CREATE DATABASE %DbName% ON %DbDisk% USING CODESET UTF-8 TERRITORY US 
DB2 CONNECT TO %DbName% USER %DbUser% USING %DbPassword% 

DB2 CREATE BUFFERPOOL BufferR2010 ALL NODES SIZE 200 PAGESIZE 8192 

DB2 CREATE REGULAR TABLESPACE REMxxx PAGESIZE 8192 MANAGED BY SYSTEM USING ('C:\db2\RemXxx\') EXTENTSIZE 256 PREFETCHSIZE 32 BUFFERPOOL BufferR2010 

Open in new window


And that works fine when DB2 Server is installed on the same compute where we installing our product.

But now we got a new life-pushed requirement - we need to create DB2 database on remote node (not on the current computer!).

Do you know - if that is possible at all?

Note: target DB2 versions are 9.x and 10.x.

Please also note: I had already tried approach described here - it does not work. It is able to catalog node, attach node - that is works ok, but the "create database xxx" command is always creating database on local node (not on the remote/attached one). :-\

Regards,
Dmitry.

Hi Dmitry,

You should be able to create the database as long as you create a connection to the instance first.

Using the Command Line Interface,:

db2
db2> Connect to {database on the desired server}
db2> Create database command
db2>quit

That should do the trick.


Good Luck,
Kent

No, for sure that will not work!
Because it is technically impossible to execute the "Connect to {database on the desired server}" if database is not exists.

Does any database on that server exist?

You don't need to actually use a database on the server, just connect to something that's on the instance.

Databases may exists but when software installed we do not know anything about such databases.

Hm... I just tried this variant:
db2 catalog tcpip node %DbNodeName% remote %DbNodeAddress% server 50000
db2 terminate
db2 list node directory 
db2 attach to %DbNodeName% user %dbUser% using %dbPassword%
db2 create database remtDb 

Open in new window


Seems it works but only with DB2 9.x or higher.
With DB2 v8.x it is reporting "SQL0901N  The SQL statement or command failed because of a database system error. (Reason "CREATE DATABASE w/ DB options requires V9.1 server or later".) SQLSTATE=58004"

Hm... need to re-test it for DB2 v8.x and v10.x.
Seems for 8.x it is not working anyway. :-\

Hi Dmitry,

The differences between version 8 and 9 are significant.  It's very believable that this doesn't work for V8, but it has been long enough that I don't remember.

V8 has been out of support for nearly 4 years.  Are there plans to upgrade that server to a newer release of DB2?

It is already posted in one of messages:
db2 catalog tcpip node %DbNodeName% remote %DbNodeAddress% server 50000
db2 terminate
db2 list node directory 
db2 attach to %DbNodeName% user %dbUser% using %dbPassword%
db2 create database remtDb 

Open in new window


And - for DB2 v8 it does not work. It works only for DB2 v9 or higher.
One of databases I was tried to do was DB2 v8.x, so that is why this question appears at all.
