Once you have the correct location, you can substitute it in to the lines above in the. bashrc to find the lines automatically added by Db2 on installation

You’ll want to replace that with your instance name. In these examples, the instance name is represented by db2inst1. There can easily be many Db2 instances on a server. If you don’t have this, ask your system admin or database administrator. For any of them, you have to have access to the server in some way and know the name of the instance owner. If you don’t know where the instance owner’s home directory is, there are several ways to find it. Hopefully you’ve placed it somewhere else. Generally, your instance owner’s home directory should not be on / or on /home. The path specified in these lines is going to vary depending on where your instance owner’s home directory is. bashrc when the instance is created to source the db2profile: # The following three lines have been added by UDB DB2. The following lines are added by Db2 to the. This directory is created in the home directory of the instance owner when the Db2 instance is created. This profile is stored in the sqllib directory. IBM provides a profile (actually two of them) that contains all the information needed to connect and run any Db2 commands you might need. Setting Up A Command Line to Run Db2 Commands Linux or UNIX – Sourcing the Db2 Profile However, there are still missing componnents, and even executing db2 from a location where it exists leads to this error message: SQL10007N Message "-1390" could not be retreived. Sometimes a developer or system administrator tries to be clever when they get that error message, and they locate the basic db2 executable directly. This indicates that minimally your PATH variable is not set up properly, but also that there are other environment variables that should be set up as well. There are a couple of common error messages that are immediately associated with a command line environment that is not properly set up.

The focus here is how to set up a basic Linux/UNIX command line for one ID so it can execute db2 commands and SQL. The focus of this article is not that broad, though. That is a slow and frustrating way to work. At the other end of a spectrum, I have actually worked on systems where I was not allowed to directly access the system – I could only tell someone else what to type via screen sharing. At one end of the spectrum, I’m handed root the second I get access to the system when all I really needed was SYSMON. Working as a consultant, I see an astonishing variety of security practices. Most other work, even that done by DBAs, can be done from their own properly privileged IDs. It is also best to use the instance owner to start and stop Db2. No one wants to go spelunking through crontabs across the system to figure out who is running backups and things along those lines.

There are a few exceptions to this – if you’re a member of a team administering Db2, you want to use the instance ID for scheduling any scripts. In sandbox environments, we may do most things as the Db2 instance owner, but in any shared environment, it is critical to security to use your own ID. Some of these variables are required for working with a Db2 environment. There are a number of environmental variables that are set when you log in to the Db2 instance owner id. I doubt a GUI will tempt me away from the command line, though I do find myself enjoying using things like Jupyter Notebook to also access the databases I support.

The values that need substitution are surround with WITH 2 BUFFERS BUFFER 1024 PARALLELISM 1 WITHOUT PROMPTING To backup your database, run the following commands in order substituting values where appropriate.

If you wish to run these from the DB2 Command Window or Windows Shell, you will need to prefix each line with the DB2 directive (db2). The following commands are designed to be run from the DB2 Command Line Processor. As a result of the need to control the user credentials that will be backing up and restoring the database, I put together the following commands that can be ran on the command line to perform database backup and restore operations, and figured I’d share these with everyone. They were having permission issues when attempting to run a database backup and restore through the IBM Control Center for DB2 on Windows. I was recently working with an off-shore developer, trying to get their WebSphere Commerce database updated to a state that it can be used with the current state of the WebSphere Commerce project I’m currently working on.
