This is the third article in a series of articles on getting started with IBM's Db2 Database, a Relational Database Management System (RDBMS) that is part of a collection of data management and analysis software. The first article, Getting Started with IBM DB2 on Linux Part I: Background and Installation Preparation, discussed the installation methods and the process of preparing for installation; the second article, Getting Started with IBM DB2 on Linux Part II: Installation With DB2 Setup Wizard, detailed the installation process using the DB2 Setup GUI wizard, both directly on a computer with a fully configured desktop environment, and remotely through an SSH connection where the GUI display was forwarded from the remote computer to the local computer by the X Window System. In this article we describe the three manual installation methods for installing Db2 Database.
Three methods are available for installing Db2 Database manually on Linux. The first is the extraction of the compressed archives of Db2 components within the larger compressed installation image. The second is by using the db2_install tool. The third and the most robust is through a command that takes as an argument, a response file, such as that optionally created by the Db2 Setup wizard. These methods were briefly introduced in the first article of this series, Getting Started with IBM DB2 on Linux Part I: Background and Installation Preparation. Each of these methods is detailed in the Sections Installing by Extracting Payload Files, Installing by Using db2_install, and Installing by Using Response File with dbsetup, below.
This installation method is simply the extraction of a set of tar.gz archives contained within the larger installation image tar.gz archive downloaded from the IBM Db2 download page. In Part I of this article series, after transferring the downloaded image to the remote computer, the installation image was extracted into the directory /home/db2user/software. As suggested by the documentation, the resulting extracted directory was renamed from, /home/db2user/software/server_dec to /home/db2user/software/ibm-db2. Within this directory is the executable file mentioned in Part II of this article series that started the DB2 Setup GUI wizard, as well as some other tools, such as the manual installation script and the prerequisite checking tool. It also contains another directory which contains in a subdirectory several levels deeper, all of the discrete components of a Db2 Database installation as a set of tar.gz files. These files are in /home/db2user/software/ibm-db2/db2/linuxamd64/FILES.
Descriptions of these files are provided in /home/db2user/software/ibm-db2/db2/linuxamd64/ComponentList_server_dec.htm, grouped by whether they are required for installation, whether they are part of a typical installation, and whether they are optional. The following screenshot shows a main Ark window showing the contents of the archive and another Ark window displaying the component list file.
So, the task of installing using the payload files, is simply to extract the files in the "List of Required Components", and the desired files from the "List of Typical Components" and "List of Optional Components" into an Db2 installation directory. The extraction is performed by first creating the installation directory, changing to the directory, and, as root, extracting each of the components to install with the command:
tar xvzf component_file.tar.gz
/opt/ibm/db2/V11.5_03 was chosen as the installation directory following the convention described in the previous articles, where the default path for installations of multiple copies of Db2 on the same computer was described. Instead of extracting each file individually, a script to prepare the installation directory and extract the desired files based on a match of the first part of the file names could be used in order to avoid tedious and error prone typing. The script could also incorporate some of the manual configuration tasks required after the extraction of the components.
It should be noted that some files listed in the ComponentList_server_dec.htm should not be installed, according to the documentation; these are files beginning with PURESCALE_ and CF_, which are only for pureScale environments, and GSKNOINST which are for installations without encryption support. Components that are only necessary for non-root installations -- components with names containing _NR_ also should not be installed for the process described here. The following listing shows the files chosen for this installation.

Another manual installation method is available in the form of a stub shell script that essentially automates the payload extraction method described above for Db2 Database server installation. It can also perform updates and installation of other products. It offers the convenience of not requiring the configuration steps in the payload extraction method described in the previous section, only requiring an instance and the necessary instance users to be created, also as described in the previous section.
When DB2 Server Edition is the product to be installed, the tool installs all required and optional components except those for systems without encryption support and the components for non-root installations. Options are available to force the installation of the pureScale components which are not appropriate for this example, and to prevent the installation of IBM Tivoli® System Automation for Multiplatforms. If a previous installation included IBM Tivoli® System Automation for Multiplatforms, the script will recognize it and make it available for use with the new installation.
The script, named db2_install, is located in the same directory as the the prerequisite checking tool and the setup wizard executable files, namely /home/db2user/software/ibm-db2. This directory was created by extracting the downloaded installation image and renaming a subdirectory in the result of the extraction. (See Getting Started with IBM DB2 on Linux Part I: Background and Installation Preparation.)

The last manual installation method is an installation using a response file. This method uses the command db2setup, taking as an argument a response file that contains the configuration of the installation, specifying such items as the installation directory, components to be installed, instances to be created that will be associated with the installed copy, instance owner and fenced instance user to be created, networking communication settings, among many others. The response files can be created by using the following methods:
In the process presented below, the sample Db2 server installation response file is used as a starting point for generating a response file to be used to install another copy of Db2 Database. The sample files, with an extension of .rsp, are located in the extracted installation image (Getting Started with IBM DB2 on Linux Part I: Background and Installation Preparation), in the renamed directory /home/db2user/software/ibm-db2/db2/linuxamd64/samples. The following listing shows the contents of the directory.
root@u1804-lab:~# ls -l /home/db2user/software/ibm-db2/db2/linuxamd64/samples total 172 -r--r--r-- 1 bin bin 27620 Nov 1 17:49 db2client.rsp -r--r--r-- 1 bin bin 43426 Nov 1 17:49 db2consv.rsp -r--r--r-- 1 bin bin 26175 Nov 1 17:49 db2rtcl.rsp -r--r--r-- 1 bin bin 57478 Nov 1 17:49 db2server.rsp -r--r--r-- 1 bin bin 9596 Nov 1 17:49 db2un.rsp
db2server.rsp is the server response file. It is a well documented -- through comments -- file of 930 lines, that contains all possible configuration items. The basic format of the file is a configuration item keyword then an equals sign followed by the value to set for the configuration item, as in for example,
FILE = /opt/ibm/db2/V11.5
If a configuration item can be assigned more than one value, the keyword is repeated on multiple lines and assigned a different value in each line. The configuration item
INSTANCE is one such configuration item. Multiple values can be assigned to this item, as in the following:
INSTANCE = inst1 INSTANCE = inst2 INSTANCE = inst3
where INSTANCE is assigned the values inst1, inst2, and inst3.
The comment character is an asterisk (
*). Optional configuration items are commented out with a single asterisk while required items are not. In both cases, default values are assigned to the configuration item. Text that serves to document the contents are double commented -- with two asterisks instead of one, to help distinguish it from commented out configuration items. In the excerpts from the response file that follow, lines that begin with a single asterisk are comments as they exist in the original sample file, lines that begin with three asterisks are lines that contain configuration items that were not commented out in the original sample but in copied, commented out, and retained for information. The lines containing modified values of configuration items appear below their commented out counterparts.
The process to use a response file in installing Db2 Database is detailed below. Here, the sample response file is used as a starting point for generating the response file, but it is generally applicable to installation with response files generated by the other methods mentioned previously.
cp /home/db2user/software/ibm-db2/db2/linuxamd64/samples/db2server.rsp /home/db2user/db2copy5.rsp
FILEconfiguration item to an appropriate path that is to be the installation directory of the new copy of Db2 to be installed. Even if it is the first copy, if additional copies are to be installed later, it may be desirable to change the installation directory from the default value to /opt/ibm/db2/v11.5_01. In the following listing, it has been modified from the default value of /opt/ibm/db2/v11.5 to /opt/ibm/db2/v11.5_05.
*** FILE = /opt/ibm/db2/V11.5 FILE = /opt/ibm/db2/V11.5_05

INSTALL_TYPEvalue as desired. The possible values are TYPICAL, COMPACT, or CUSTOM, which specify, respectively, the installation the Db2 Database components shown in the "Typical" section of the ComponentList_server_dec.htm (Section Installing by Extracting Payload Files) file, a minimal set of components, or a custom selection of components. Whatever the choice, required components are installed automatically. If CUSTOM is selected, the components to be installed must be specified, as shown below.
*** INSTALL_TYPE = TYPICAL ** TYPICAL, COMPACT, CUSTOM INSTALL_TYPE = CUSTOM ** TYPICAL, COMPACT, CUSTOM
COMPconfiguration item. A commented out line of the form
*COMP = Db2_COMPONENT_NAMEexists in the file for each of the installable Db2 Database components. Components to install can be specified by simply commenting out each line that sets the COMP value to a desired component to install. Like the
INSTANCEconfiguration item, mentioned previously,
COMPis a configuration item that can be given multiple values, by assigning each value on a separate line. The following listing shows the COMP lines that were uncommented for this installation.
COMP = ACS ** Integrated Flash Copy Support COMP = DB2_SAMPLE_DATABASE ** Sample database source COMP = DB2_UPDATE_SERVICE ** DB2 Update Service COMP = FED_DATA_SOURCE_SUPPORT ** Federated Data Access Support COMP = GUARDIUM_INST_MNGR_CLIENT ** Guardium Installation Manager Client COMP = INSTANCE_SETUP_SUPPORT ** DB2 Instance Setup wizard COMP = IINR_APPLICATIONS_WRAPPER ** Application data sources COMP = IINR_SCIENTIFIC_WRAPPER ** Scientific Data Sources COMP = IINR_STRUCTURED_FILES_WRAPPER ** Structured file data sources COMP = JDBC_DATA_SOURCE_SUPPORT ** JDBC data source support COMP = ODBC_DATA_SOURCE_SUPPORT ** ODBC data source support COMP = TEXT_SEARCH ** DB2 Text Search
INSTANCE. The values of the INSTANCE keyword are an identifier that allows multiple instances to be created as specified in the response file. Here the line containing the INSTANCE keyword, with a value of DB2_INST is commented out, and two INSTANCE lines are added, the first specifying an INSTANCE keyword value of inst1 and the second specifying inst2. The INSTANCE value in the response file created by the wizard, while only having one INSTANCE value used this format.
*** INSTANCE = DB2_INST ** char(8) no spaces INSTANCE = inst1 ** char(8) no spaces INSTANCE = inst2 ** char(8) no spacesThis keyword allows multiple instances to be created and configured in that these values are prefixed to instance configuration items when specifying the properties of each instance. For example, if two instances are to be created, the INSTANCE configuration item is assigned two values, as was done above. Instance specific configuration items are then prefixed with these values followed by a dot (
.) to distinguish between the two instances, as in:
instance_value_1.instance_specific_configuration_item = instance_specific_configuration_item instance_value_2.instance_specific_configuration_item = instance_specific_configuration_itemThe prefix specifies to which instance the same instance configuration item applies. This will be apparent when actual instance specific configuration items are assigned, below.
*DB2_INST.NAME = db2inst1 ** char(8) no spaces, no upper case letters inst1.NAME = db2inst5 ** char(8) no spaces, no upper case letters inst2.NAME = db2inst6 ** char(8) no spaces, no upper case lettersHere we see how the values of the
INSTANCEconfiguration values are used to prefix the instance configuration item, in this case
NAME. The username of the instance owning user of each instance will be the same as the instance name.
*** DB2_INST.GROUP_NAME = db2iadm1 ** char(30) no spaces inst1.GROUP_NAME = db2iadm1 ** char(30) no spaces inst2.GROUP_NAME = db2iadm1 ** char(30) no spacesThe primary user group name specified here will be created by the installer using the low level Linux utility groupadd to create the group if it does not already exist and a primary user group ID (GID) assigned. The GID to use for a newly created can be specified in another configuration item, but if it is not provided, a GID will be automatically assigned following the configuration of the groupadd command. In this case, the primary user group specified already exists as it was created by the Db2 Setup wizard (Getting Started with IBM DB2 on Linux Part I: Background and Installation Preparation) and the new instance owners will be assigned to this primary user group.

Here port number values of 50004 and 50005 are assigned to the two instances created by this installation, reserving the intermediate port numbers -- although not configured in this procedure -- for instances created by the previously described manual installation methods. The port numbers specified correspond to the instance name in that the last digit of the port number chosen for each instance is the same as the last character of the instance name.
MAX_LOGICAL_NODEfor each instance. These values define a range of ports reserved for each instance during installation. The range for an ESE instance is between FCM_PORT_NUMBER and MAX_LOGICAL_NODE.

The last character is the same as the the last character in the instance name and thus the same as the last character in the instance owner username. The installer will create the specified user if it does not already exist using the useradd command. Another setting also exists to manually specify the user ID (UID) of the fenced user, but if not specified the installer will automatically assign one (following the configuration of useradd).

If it does already exist the installer just assigns the new user to the group. The GID to use for a newly created can be specified in another configuration item, but if it is not provided, a GID will be automatically assigned following the configuration of the groupadd command. In this case, the primary user group specified for the fenced user is one that already exists as it was created by the Db2 Setup wizard (Getting Started with IBM DB2 on Linux Part II: Installation With DB2 Setup Wizard) and the new instance owners will be assigned to this primary user group.

As we have seen in this and the previous articles of this series, IBM offers many methods for installing Db2 Database, from the simple GUI of the Db2 Setup wizard and the equally simple CLI installation tool, db2_install, to the robust response filed based installation that allows for all configuration items to be declared in the input response file. Both the GUI wizard and the response file method are launched by the stub shell script db2setup -- with different options -- which then calls other tools as appropriate to perform the actual installation and provide an interface as necessary.
