System requirements for client products
Before you install client products, make sure that your computer meets the system requirements.
Operating system requirements
The Client SDK system requirements web page lists supported operating systems: http://www.ibm.com/support/docview.wss?uid=swg27016673. For system requirements for the IBM® OpenAdmin Tool (OAT) for Informix®, see System requirements for IBM OpenAdmin Tool (OAT) for Informix.
Install the required operating system patches and library files that are listed in the machine notes for your operating system. The machine notes are in therelease information or in the doc directory of the media files before installation.
UNIX, Linux, Mac OS X: The directory on which you plan to install the database server must be local or an NFS-mounted file system with regular operating-system files.
Windows: The drive on which you plan to install the database server must be formatted with NTFS and must have 8.3 file name creation enabled. For Windows 7 and subsequent Windows versions, turn off User Account Control (UAC) security before you install client products.
Disk space and memory requirements for installation
The following disk space and memory requirements for installing the database server are approximate. The requirements for some operating systems might be lower.
- Disk space
- Client SDK: approximately 200 MB
- Informix Connect: approximately 175 MB
- Some installation choices require additional disk space. The installation application informs you of the total disk space required by your setup before you copy the binary files to your computer.
- RAM
- UNIX, Linux , Mac OS X: 512 MB
- Windows: 256 MB
- Temporary disk space
- You can change the location of the temporary directory by setting the IATEMPDIR environment variable before you run the installation application.
- UNIX, Linux, Mac OS X: 1 GB free space is required in your temporary directory (/tmp by default). If the temporary directory does not have enough space, the installation application attempts to write the information into the home directory of the user account.
- Windows: 1 GB free space is required in your temporary directory (C:\tmp by default).
Java runtime environment (JRE) requirements
The installation application bundles a Java™ runtime environment that it requires. However, check the machine notes for your operating system platform to determine whether the installation application requires a preinstalled JRE.
Restrictions
Linux: Client SDK does not support RPM installations.
