They tend to be very powerful ids if anyone else can find the password. Please never store database passwords in plain text. When youвЂ™re logged into the server, youвЂ™re already authenticated, and Db2 recognizes that. This is because Db2 relies entirely on the OS or an external authentication facility like LDAP for authentication. Note that in the first example, I did not have to provide a password. If you need to use a different id, you have to specify the id name like this: This connection syntax only works if you are logged in to the server with an id that has the connect privilege on the database. вЂњsampleвЂќ in this case is the database name. Once you are at a properly configured command line, connect to a database like this: On Windows, to get to a command line you can run вЂњDB2 Command WindowвЂќ as an administrator from the IBM DB2 menu for that Db2 copy. The home directory of the instance owner cannot easily be changed after instance creation. The instance ownerвЂ™s home directory contains a file structure critical to the functioning of db2 in a directory called sqllib. Each instance has an id associated with it called the instance owner. Each database is associated with one and only one instance. In the above, $INSTHOME is the instance ownerвЂ™s home directory. Sourcing the db2profile can also be done at the command line like this: For a local command line connection on a Linux or UNIX server, I ssh to the server, and make sure I have sourced the db2profile of the instance in question. For me, and most DBAs, the simplest connection is from a command line. The simplest way to establish a connection is entirely dependent on your background and experience. Command Line Connection Local Command Line Connection Database servers should generally not be accessible from the open internet. Others may require you have the right application drivers.Дepending on firewall rules, you may even be able to connect from your laptop or desktop to a database server, though this will likely require a VPN connection or being on the right network. Some connections will require a Db2 client for this to work. If you have an application server that is able to access the database server, you can connect from the application server. If you have the proper ID, you can ssh or rdp to a server and connect to the database locally on the server. Grant or revoke database or object-level permissions and authorities.Create, alter, and drop tables, indexes, views, stored procedures and other database objects.

Make changes to some database configuration areas.

Once you are connected to a database, if you have permissions, you can take actions like: If defined within a database, connecting may also execute the CONNECT_PROC stored procedure that can be customized per enviornment.

Connecting also performs authentication using the LDAP or operating system methods available. That coordinating agent also has some small memory areas associated with it that will be enlarged as needed. Often you are assigned a coordinating agent (thread), which will perform work for you in the database. When you connect to a Db2 database, Db2 allocates certain resources. It applies to Db2 for Linux, UNIX, or Windows.

This entry focuses on how to establish a connection to work with a Db2 database. A Db2 connection is made at the database level, and not at the instance or server level. If you have any changes, recommendations, or comments, please let me know by using the comment form below.Connecting to a database is required before most actions can be taken on the database. 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 IвЂ™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 IвЂ™m currently working on.
