During the installation of IDS 11.50, Program Group folder is opened and Start Menu shortcuts are added. If, these actions were optional then it would make IDS more embeddable with other applications, which uses IDS in background. Customers who are embedding IDS as part of their software package usually desire near-complete invisibility.
This request was met by adding a new comma-line option “hidden” for instillation. This option will prevent creation of start menu shortcuts and suppress the Program Group folder from popping-up. Users can use this option by invoking the setup.exe (IDS 11.50 installation) from command-line and supplying “–hidden” option with the same command.
$ setup.exe -hidden

Previous version of JDBC 3.50 could not be installed on Windows 64-bit using 64-bit JRE. Installing JDBC 3.50 gave an error "Directory not writable" for all directories. Same error message was received, even after running all the process as administrator by turning UAC (User Account Control) off. Workaround for this problem was to use 32-bit JRE on Windows 64-bit to install JDBC 3.50.
This problem was solved in IDS 11.50. Now JDBC 3.50 uses newer version of Install Shield, which allows for JDBC 3.50 to be installed on 64-bit Windows using 64-bit JRE. Now, users no longer have to use 32-bit JRE to install JDBC 3.50 on Windows 64-bit. This makes users life easier, since users do not have to set up 32-bit JRE on 64-bit Windows.

Introduction:In most cases the Informix error codes are very good at explaining why there is a problem and how to fix it. Finderr(Error Message Utility), is the utility shipped with IBM Informix Dynamic Server and client products(CSDK and IConnect) that’s helps to check an error code and returns error messages corresponding to IBM Informix error numbers.
Problem:Finderr uses WinHelp. The Help for this program was created in Windows Help format, which was used in previous versions of Windows and it is not supported in the newer flavors of Windows Operating Systems like Vista or Windows 2008. Windows Vista and Windows Server 2008 are not shipped with Winhelp application. So you will get error messages popping up while executing finderr utility shipped with IDS 11.50 on Windows Server 2008 and Vista:
The GUI finderr program supplied with CSDK and IConnect also doesn't work on Windows Vista or Windows Server 2008. The execution of finderr utility in client products pops-up the following error messages.
For Windows 2008:
In IDS releases prior to 10.00.TC5, the Informix Dynamic Server(IDS) Windows Service was allowed to log on only as user informix. Launching the IDS installation program setup.exe with the -system command line argument (only) will install IDS and create a new instance running as the Windows Local System user, bypassing screens which prompt for informix user password(informix user does not get created when this option is used).
Starting with version 11.50, you can install IDS on Windows as the local system user account by selecting the Local System User option right on the IDS Server configuration Setup panel. This option is available only in custom mode of installation.
However user can choose not to create an informix user account at all, but we have to note that Enterprise Replication between Dynamic Server on UNIX and IDS on Windows Operating System will not work if informix user and Informix-Admin group is not present.Along with the “Start database server as Local System User” checkbox another checkbox “Do not create user informix account” is also provided on the same panel which is greyed out unless the user picks the System User option.

Suppose you have an application which depends on IDS. Your business requirement is application must starts after a successful IDS memory initialization. Previously there was no way you can validate the return code of oninit process to make a decision whether or not IDS initialize successfully. So, if you have a script that automatically starts IDS and the application respectively, it possible the application may start even though IDS failed to initialize.
DB_LOCALE and CLIENT_LOCALE are compatible if ...
a locale consisting of the language_terriorty from CLIENT_LOCALE and the code set from DB_LOCALE exist
CLIENT_LOCALE = de_de.850
Here, both the locales are using same code set, 850 which is supported by both en_us and de_de, that is, US English and Germany German.
Hence, they are compatible.
DB_LOCALE = de_de.cp1252 (code set 1252, its hex value 04e4)
ii) Conversion between CLIENT_LOCALE's code set, 850 and
should see the above listed files exists.
Hence, they are compatible locale.
DB_LOCALE = cs_cz.8859-2 (code set 8859-2, its hex value 0390)
DB_LOCALE = en_us.utf8 (code set utf8, its hex value e01c)
are not compatible because Israelian hebrew (iw_il) does not support utf8 encoding.
That is, there is no such locale file to support utf8 encoding by Israelian hebrew.
Note: If a locale file is not available in your INFORMIXDIR, check the Informix International
The value of locale variable, CLIENT_LOCALE or DB_LOCALE can be broken into 4 parts.
1 2 3 4
Conventional, I represent this as ll_tt.xxxx@xyz, where ...
tt ........... represents the Territory, or cultural convention.
xxxx ....... represents the Code set Name or the Code set Number supported by the locale and
xyz ......... represents the Modifier. This is the only optional part in a locale value.
The modifier, sometimes refered as variant, modifies the cultural-convention settings that the language and territory settings imply. It usually indicates a special localized collating order that the locale supports.
Let us look at an example.
CLIENT_LOCALE = de_at.1252@euro
- at ............ the territory, Austria
- cp1252 ... the code set used for the encoding and
- euro ....... the modifier used for the locale
So, this is German language locale, for Austria, using cp1252 encoding and euro modifier.
Now, to check if this locale file exists, where to lookup ?
To lookup for locale files for language (ll) and territory (tt), we check under $INFORMIXDIR/gls/lc11/ll_tt directory.
Next, under the specified locale directory, look for files with name represented by hex value of the code set name/ code set number, along with modifier name if modifier is specified, with an extension .lco
In our example, hex value for Code set cp1252 is 04e4 and modifier euro is used. So, we will look for file 04e4euro.loc under directory $INFORMIXDIR/gls/lc11/de_at.
How and where to find the hex value for a Code set name ?
We can find the information in file
In the registry file ...
- second column is code set number
- third column is the hex value of the code set number, and
- fourth column, is either blank or has comment about the code set.
We get the following value.
Latin-3 57346 0xe002
Here, both locale values are valid, representing the same code set.
DB_LOCALE = de_de.cp1252 or de_de.1252 .... both values are valid and they represent the same code set
CLIENT_LOCALE = de_at.cp1252
CLIENT_LOCALE = de_at.cp1252@euro
IDS 11.50 introduced a new installation wizard (installer), which makes life easier than in past releases to set up an instance to use a variety of database clients. In this section we will discuss how to set DRDA connection during installation process.
IDS 11.50 made a significant improvement in installation process. Started with IDS 11.50 informix introduced a new versatile installation wizard (installer), which can automatically creates a customized database server configuration file (ONCONFIG) suitable for your system environment and create a demonstration database server during installation process.
Upgrading Informix Dynamic Server Version 10.00 to Versions 11.10 or 11.50:
When installing IDS 11.10 or 11.50, if you choose the option "Upgrade from the previous version", all the server binaries will be upgraded to the newer version(s) automatically.
Upgrading Informix Dynamic Server from Version 11.10 to 11.50:
When installing IDS 11.50 on Windows, direct upgrade from IDS 11.10 is not supported. If “Upgrade from the previous version” is selected the following message pops up. Installer stops beyond this point.
Since the support to install both 11.10 and 11.50 on the same machine exists, it is recommended to choose the option “Install into a default/different directory” (shown in the panel below) to install IDS 11.50. Note: This will not upgrade IDS 11.10 to IDS 11.50.
As part of providing a folder name to install the product, a completely new path must be supplied. If the folder selected already contains binaries from IDS 11.10, then the following message pops up.
User can respond to the question “Do you want to select another folder? “. Clicking “yes”, the installer returns to the destination panel where they can provide a different folder. Clicking No, the installer goes to finish panel
The recommended approach to upgrade to 11.50 is
