That's where you define users for the remote DBMS. The remote DBMS address (domain name or IP address). Must be the same as the LINKNAME specified in SYSIBM.LOCATIONS. Note that the location name must match the remote database name or you'll get an "SQLCODE = -30061, ERROR: RDB NOT FOUND" error. That's where you define remote locations. Here are some explanations of important CDB columns: Let's look at an example of how the CDB tables of the catalog can be populated. There are many ways to configure communication and authentication between Db2 for z/OS and Db2 LUW - using trusted contexts, with and without passwords, etc. Connectivity Cheat Sheet for DB2 Universal Database.Populating the communications database for use with TCP/IP.Here are some useful resources about CDB: The communications database (CDB) in Db2 for z/OS is a set of catalog tables which define remote DBMS systems (both z/OS and non-z/OS) to the Db2 subsystem.

Connect to the database (the database name is "SAMPLE" in our case) and execute a SELECT statement against the sample database.ĭb2 'CONNECT TO SAMPLE' & db2 'SELECT * FROM EMPLOYEE' Communications Database.Create a sample database using the following Db2-supplied utility:.

The following command executes the su command required to login as a specific user, "db2inst1" in this case:ĭocker exec -ti db2 bash -c "su - db2inst1" Check the container logs for the "Setup has completed" message:.The "ibmcom/db2" is the name of the Docker image we are going to use.ĭocker run -itd -name db2 -privileged=true -p :50000 -e LICENSE=accept -e DB2INST1_PASSWORD= -e DBNAME= -v db2:/database ibmcom/db2 We'll need to specify the database name, the password, and the port number to be mapped to Db2's port 50000. The -e option just sets environment variables to be used by the Db2 installation (refer to the Docker image page for more information on environment variables). The volume can have any name, but in our case we'll use "db2": We'll need to be able to save (persist) the data of our Db2 container.Open a command prompt to run the following commands.(Refer to the Docker CLI documentation for the descriptions of the parameters for each of the following commands):
DB2 UNIVERSAL DATABASE FOR Z OS INSTALL
Here are some simple steps to follow in order to install Db2 LUW using Docker under Windows.
DB2 UNIVERSAL DATABASE FOR Z OS WINDOWS
The Linux version is more feature complete and is production-ready, but for the sake of experimenting, the Windows version of Docker may be used as well. ĭocker itself can be installed under Windows or Linux. There's a Db2 LUW Docker image with installation instructions available here.
DB2 UNIVERSAL DATABASE FOR Z OS SOFTWARE
Docker allows you to describe the exact software required (like operating system version, etc.) for a specific software product, providing a more reliable option to install and operate software. We are going to use a more solid installation option - Docker. The Windows installer may cause various problems during installation.
DB2 UNIVERSAL DATABASE FOR Z OS FREE
First of all, use the latest version (11.5 at the moment) of the Community Edition of Db2 LUW, which is free but limited to 16GB of memory, 4 CPU cores, and 100GB of database size - plenty of resources for experimenting.ĭb2 LUW can be installed directly under Windows, Linux, or other operating systems. If you want to experiment with your own independent instance of Db2 LUW then there's a simple way to do that. In this article, we are going to focus on Db2 LUW. Therefore, Db2 for z/OS supports communication with other DBMS systems that also support the DRDA standard. Some examples of DBMS systems that support the DRDA standard include: Db2 for z/OS supports the DRDA standard (Distributed Relational Database Architecture) to intercommunicate with other DBMS systems.
