xiv IBM Informix Dynamic Server Installation Guide for Windows
Chapter 1. Preparing to Install IDS on Windows Read the following information and complete the tasks appropriate for your installation environment.
For information on how to create groups and add users to groups, see your Windows documentation. Multiple Copies of IDS on One Computer Multiple copies of IBM Informix Dynamic Server can run on the same computer. The copies can be the same or different versions of the product. | | Multiple copies of different versions If your computer hosts more than one installation of IDS, each instance has a corresponding IBM Informix Dynamic Server program group on the Start > Programs menu.
Related tasks “Installing a Copy of IDS on a Computer” on page 2-1 Choosing Your Installation Setup Using the installation application, you can choose a typical or custom setup for loading IBM Informix Dynamic Server and other products to your system. Typical setup installs the full IDS product, while custom setup lets you exclude product features in order to minimize the installation footprint (disk size).
instance to function with the DRDA protocol after installation by using the instmgr.exe utility (see “Server Instance Manager Command-Line Options” on page 2-14). v Installing database server to run as local system user: To install IDS as a local system account on Windows, you must select a custom installation and complete the configuration setup accordingly. This lets the IDS log in as a Windows service, instead of user informix.
Conversion and Reversion Support Framework required for migrating to and from other versions of the database server XML Publishing Set of functions to publish SQL queries as XML Global Language Support The feature files to support languages, cultural conventions, and code sets. These files are not required if your default locale uses American English, which is the default language in IDS when no GLS feature is installed.
dbload Utility For loading data into databases or tables that IBM Informix products created. Use the dbload utility to transfer data from one or more text files into one or more existing tables. High-Performance Loader (HPL) For loading or unloading large quantities of data efficiently to or from a database. Use HPL to exchange data with tapes, data files, and programs, and convert data from these sources into a format compatible with IBM Informix databases.
Basic demonstration database server: Select the Initialize Server checkbox in the installation application and ensure that the settings for the server name, service name, port, and server number are accurate. Instance Configuration Wizard: A more customized database server can be created with the Instance Configuration Wizard. Select the Initialize Server and Enable the default configuration file checkboxes to use this feature.
Instance Configuration Wizard The Instance Configuration Wizard is an installation option that automatically creates a database server configuration file customized to your system environment. You can use the Instance Configuration Wizard on a Windows computer when you install using a custom setup in GUI mode. In the installation application, the checkboxes for Initialize Server and for enabling a custom configuration file must be selected to invoke the wizard.
Role separation provides increased database security because the database server splits administrative tasks into mutually exclusive roles. If you do not enable role separation, the Informix-Admin group performs all administrative tasks. For detailed information about the role separation feature, see the IBM Informix Security Guide. You cannot turn off role separation after you enable it.
Local Installation If you do not plan to have workstations access a domain controller, install the database server on a local computer. For a local installation, you should have administrative privileges. Domain Installation with Domain Administrator Privileges Domain installation is useful if you run the database server on several computers and want a central security mechanism.
Chapter 2. Installing IDS on Windows The following topics explain your IBM Informix Dynamic Server and IBM Informix products installation choices. Troubleshooting information is also included.
2. Select Install Products from the Launchpad and click Next. 3. Select to install IBM Informix Dynamic Server and click Next. 4. Select the option to install a new instance when the installation application lists existing IDS instances and click Next. 5. Select the option to install in a different directory and click Next. Complete the prompts in the server installation application for a typical or custom setup.
Completing the installation program loads a configured database server with a typical setup. For information on changing the configuration or configuring a database server manually, see “Database Server Configuration After Installation” on page 3-4 and “Configuring IDS Manually” on page 3-6. The installation creates a log file in %INFORMIXDIR%\logs\ which contains installation activity of the IDS installation. In addition, there is a manifest file (%INFORMIXDIR%\etc\manifest.inf).
e. See the disk-size information about your selected component and feature configuration, as well as the amount of free space on your drive, under the GUI feature tree. 8. Enter applicable user account information and, optionally, enable role separation. If the user informix account does not exist on your computer yet, the installation application creates one and requires you to create a password for it. a.
window that appears directly afterwards. (See “Instance Configuration Wizard” on page 1-8 for more information about this option.) c. Optional: Select the Enable DRDA Support checkbox if you want the instance to have a server alias and port for Distributed Relational Database Architecture (DRDA) connections. DRDA is designed for interoperability with IBM Data Server clients. If you install IDS without this option, you can still add DRDA connectivity to the instance later without reinstalling. 13.
For information on how to silently install other IBM Informix products, see their product documentation. Related tasks “Installing a Copy of IDS on a Computer” on page 2-1 “Performing Silent Uninstallations of IDS” on page 4-2 Using a Customized server.ini File for Silent Installation Copy the server.ini file in the Dynamic Server installation media, customize it with a different file name, and run the silent installation command.
1. Start the installation application by running the following command: setup.exe -r -f1"path\response_filename.ini" path\response_filename is the full path and file name of your response file The f1 argument is optional. If you do not specify the location and name of the response file with the f1 argument, by default the installation sequence is saved in %WINDIR%\setup.iss. 2. Complete the GUI custom installation of the product. 3. Copy your .
| Specifying an Installation to Modify | | | | | | | | | If the Dynamic Server version that you want to install matches the version on the target computer, the information recorded in your response file determines whether the silent installation adds a new copy of the database server or modifies the existing installation. Therefore, if your response file recorded a new installation, you do not need to include the -multiple option in the silent installation command. Similarly, if you ran the setup.
Setting Up Cluster Installations Complete the following tasks to cluster two computers.
Setting Up a Cluster Installation To set up a cluster on the primary node: 1. Run the following command on the primary node: clusterIT_a. The Informix ClusterIT - primary Node window appears. 2. Fill out the information about networking environment, machine names, and configuration for installing IBM Informix Dynamic Server: a. In the DBSERVERNAME to be clustered text box, enter the name of your unclustered IDS instance. b.
7. Uninstall any previous IDS installations on the secondary node. Implementing a Cluster on the Primary Node When you run the clusterIT_a utility on the primary node, ClusterIT performs the following tasks: v Extracts the resource .dll (ifxdb920.
3. Click Convert to Cluster. After the ClusterIT utility completes, IDS starts on the secondary node. After implementing a cluster environment on multiple nodes, you can find a record of the ClusterIT utility activities in the clusterIT.log files, one for clusterIT_a in the primary node directory, and one for clusterIT_b in the secondary node directory where the ClusterIT executables were installed.
| | While the database server engine is upgraded by this task, the preceding steps do not change your databases. | To start the IDS instance, you must initialize the server manually. Multiple Residency You can set up multiple independent database server environments on the same computer Complete the following tasks to set up multiple residency.
2. Select the Installation Method, and click Create New to create a new instance of the database server. 3. Follow the prompts. After you enter the required information, the Server Instance Manager installs services, records environment variables, updates the registry, and creates an onconfig file for the new database server instance. Server Instance Manager Command-Line Options The instmgr.exe utility extends the ability to configure an IBM Informix Dynamic Server instance with command-line options.
Table 2-2. instmgr.exe Utility Options (continued) Option Meaning -system Create database server instance that runs as local system user instead of user informix. (IDS must be installed as local system user to use this option.) Troubleshooting Installation Problems This section describes some common installation problems and the corresponding solutions for users who receive their product materials directly from IBM.

Chapter 3. Post-Installation Tasks on Windows Review the following information after installing IBM Informix Dynamic Server.
(Custom installations: If you enabled role separation when you installed the database server, you could have changed the name of the Informix-Admin group.) v Automatically assigned the informix user account, under which the database server runs, to the Informix-Admin group and to the Windows Administrators group.
Table 3-1. IBM Informix Dynamic Server Program Group (continued) Menu Item Description Server Instance Manager Creates and configures new server instances and removes configured server instances. server-name Opens a Command Prompt window for an initialized database server instance. You can use that window to run DB-Access and certain command-line utilities such as onstat, oncheck, and onspaces. (The oninit utility is designed to be started by a service rather than from this window.
v To initialize and then start the database server, run the command with the -iy option. starts server_name -iy Warning: If you run the -iy switch on a database server that has IDS databases, the data is deleted. Stopping the Database Server To stop the database server from the Control Panel, you must be a member of the Windows Administrators group. To stop the database server from the command line, you must be a member of the Informix-Admin group. To stop the database server: v From the Control Panel: 1.
The database server uses configuration parameters, set in the onconfig file, during initialization. For more information about configuration parameters and the onconfig file, see the “Configuration Parameters” chapter of the IBM Informix Dynamic Server Administrator’s Reference. To determine how many instances of the database server are installed, run the Server Instance Manager program. To run the Server Instance Manager program, choose Start > Programs > IBM Informix Dynamic Server 11.
Default Sbspace Name, Location, Size, and Page Size An sbspace is a logical storage area that the database server uses to store smart large objects (CLOB and BLOB data). The default sbspace is the location in which the database server stores a smart large object if you do not specify an sbspace name when you create the smart large object. The database server also uses the default sbspace to store user-defined statistics.
c. Specify the name of the default sbspace. d. Specify the primary and mirror storage location and disk-space size for the default sbspace. 3. Specify the computer to use for shared server definition for your database server and administrative tools. The installation program installs services on the computer and configures the database server. 4.

Chapter 4. Modifying IDS on Windows The uninstallation application facilitates uninstallation and reinstallation of IBM Informix Dynamic Server, as well as modification of installed features of a database server instance.
| | | | -instnum Specifies the installation number of the copy that requires maintenance. For example: | | | | | Where: v installation path is the full or relative path to the location of the IDS installation that you want to alter. v installation number is the unique number that identifies each copy; this number was automatically generated when the copy was installed. v X:path\response file is your drive, path, and response file name of the file (uninstall.
The command records the uninstallation options as you perform them and stores them in a response file. If you do not specify the location of the response file, by default the uninstallation sequence is saved in %WINDIR%\setup.iss. 2. To perform the silent uninstallation on another system, or to uninstall from the same system at a later time, specify the appropriate response file with this command: setup.exe -s -f1"X:path\uninstall.ini" | | | | | | | | | | | | 3.
