IBM DB2 Client￼4 min read
An Overview of the IBM DB2 Client:
This article provides an overview of the IBM DB2 client. It also includes information on installing the client and connecting to a database or geodatabase in DB2.
This article also discusses security settings for DB2 objects. Once you’ve installed the client, you’ll be ready to start configuring your DB2 database.
Installing the IBM DB2 client:
In the installation wizard, choose “Install the IBM DB2 client on this computer” and follow the steps. If you want to run the installation without the UI, you must select “Ignore the UI.” If you want to install the application silently, you must enable the security of your operating system.
Before installing the IBM DB2 client, you must define the database name. This name is required for connection to the control center.
However, the instance name is not necessary for connection to AS400. Once you have defined the database name, you can proceed with installing the IBM DB2 client for Windows.
Next, you must install the ODBC driver on the client machine. This can be done manually by using the Command Line Processor (CLI) or by using a command-line program.
If you want to install the ODBC driver on the client, you must specify a directory where the ODBC driver is located.
Connecting to a database or geodatabase in IBM DB2 Client:
Connecting to a database or geodatabase is an important step when using the IBM DB2 Client. The client is available for many operating systems and is compatible with all Db2 server versions.
However, there may be some differences between Db2 and its clients, and certain steps must be followed in specific environments.
Depending on the environment, the database server may be accessed through application servers. This requires the right application drivers and firewall rules.
Desktops may also be able to connect, but a VPN connection is usually required. This is because the database server is not accessible from the open Internet.
To connect to a Db2 database, you must have installed the appropriate software. Depending on your system, you can install the 64-bit or 32-bit version of the client. You must also install the IBM Data Server Runtime Client for Db2 on the computer you’re connecting to.
Managing a database in DB2:
Managing a database in IBM DB2, an object-oriented relational database management system, is the process of setting up a database in a database server.
The database server can have many instances, and each instance has a unique port number. In addition, DB2 installations can be configured to use 4 types of OS groups. The SYSADM group, for example, is used for the administration of multiple databases of a single database manager instance.
Similarly, the DBADM group is the top-level grant for a single database, and the SYSADM group is used for managing multiple databases in a single database manager instance.
Managing a database in IBM DB2, formerly known as Database 2, is similar to managing a SQL database, but it uses a different engine.
This allows developers to write SQL code for one platform and run it on another. Consequently, if you’re trying to develop a database on the IBM DB2 Client, you can apply the latest Level Set PTF (20.0.04) to get more information on how to manage a database in DB2.
Configuring security for DB2 objects:
IBM DB2 Client allows users to configure security for DB2 objects. By default, extended security is disabled. To enable extended security, run the db2extsec command and make sure you belong to the local Administrators group.
This will enable you to modify the ACL of protected objects. This command can be repeated as many times as you want. Note that you cannot disable extended security without also running the db2extsec -r command.
Once you have configured Db2 security, you should change the default group ID to the group you want to configure. You can set the default group to SYSADM and then modify the group name. Ensure that you have a second app server configured as well.
If you want to enable a TCP connection, you should enable SSL. This feature is a good security measure. However, you should not use TCP connections on a Db2 system unless you are absolutely sure of the security of the connections.
