Mimer SQL on Linux (32-bit)

This product is Mimer SQL Engine for Linux systems based on processors supporting the IA-32, or x86-32, architecture, running kernel version 2.6 or later. Please, see the section Supported Architectures for details on supported and unsupported platforms.

Mimer SQL on Linux 2.6 is using the NPTL threads package (Native Posix Threads Library) and is enabled for Symmetric Multi Processing (SMP). In addition, the new I/O package supported in the Linux 2.6 kernel is used, which means that true asynchronous I/O can be utilized.

For specific details of the capabilities in Mimer SQL 9, please see the dedicated Mimer SQL 9 page.


Mimer SQL provides small footprint, scalable and robust relational database solutions that conform to international ISO SQL standards. It is very well suited for high performance mission critical systems as well as for mobile and embedded appliances. In addition, Mimer SQL is equipped with an extensive multilingual support using collations.

A Mimer SQL Engine distribution contains several components, as described below.

Default License

A default license for testing and development is included, it allows up to ten concurrent users. For license upgrades, please contact Mimer SQL sales.

Database Server

The Mimer SQL database server is a single, multi-threaded process with SMP scalability.

Clients using TCP/IP can access the server. For clients running on the same platform, a shared-memory based communication method is used.

Embedded SQL

An embedded SQL preprocessor is included. It enables SQL commands to be embedded in programs written in C, C++ and FORTRAN. The embedded syntax complies with the ISO standard for embedded SQL.

JDBC Driver

A JDBC driver is included in the distribution. The driver is a type 4 driver, which means that it is written entirely in Java. This provides the driver with full portability so that it can be copied or downloaded to any Java enabled platform. The driver uses TCP/IP to access a Mimer SQL server (version 8.2 or later) on any platform. For details on the JDBC drivers, please refer to the Mimer JDBC Driver Guide.

ODBC Driver

The Mimer ODBC driver is a client library that enables applications to access Mimer SQL database servers running on any platform. The driver complies with the ODBC 3.52 specification. In the Linux ODBC environment it may vary how SQLWCHAR is defined and used, i.e. if it refers to a two or four byte type. To handle both these scenarios, two ODBC driver libraries are provided, libmimodbc2 and libmimodbc4, respectively.

On Linux you can choose to use a third party ODBC Driver Manager that enables applications to dynamically load drivers for different database products. But, you can also choose to link your applications directly to the Mimer ODBC driver, without using any Driver Manager. In the latter case we suggest usage of the provided ODBC header files, introduced by including the mimcli.h file. This means that SQLWCHAR will by equal to wchar_t - by default a four byte type which implies that the ODBC driver library should be used.

For a proper Unicode behavior, please note that internationalized programs must include the locale.h header file and call the setlocale() operating system function to initiate a specific language operation. This can be done by calling setlocale() as follows:

setlocale(LC_ALL, "");

Generally when executing an ODBC application, a platform specific Mimer ODBC driver has to be installed on the client side. This driver can then access Mimer database servers on any platform. There is no need to install any special software on the server side in order to use ODBC.


The Mimer SQL product for Linux includes the Mimer SQL manuals in Adobe PDF format.


The main utility used when administering and managing a Mimer SQL database is the DbVisualizer Java based tool, which is provided within the delivered product package. Please note that upgrading to an extended professional DbVisualizer version can be made at Minq Software AB.

Mimer SQL also includes command-line utilities for creating databases, load and unload of data, backups, interactive SQL statement execution, etc.

In addition, the Mimer SQL distribution contains an example database, examples of database programs and SQL statements.

When Mimer SQL Engine is installed on Linux it appears in the desktop like in the following example:


Level-2, an older database API, is not supported on Linux platforms. If used, you will receive an error message.

Supported Architectures

This product runs on processors built on the Instruction Set Architecture (ISA) called IA-32, or x86-32. Several suppliers are providing processors that supports IA-32, for example, Intel (Pentium, Celeron, Xeon, ...) and AMD (Athlon, Duron, Sempron, ...). Mimer SQL for Linux supports all of these.

In addition, an extension to IA-32 is available called AMD64, or x86-64. This architecture is backwards compatible with IA-32. Accordingly, Mimer SQL for Linux can be used on processors based on AMD64. For example, the Athlon-64 and Opteron processors from AMD supports AMD64.

Intel has also developed processors supporting the AMD64 architecture. They have named their variant Intel 64. This architecture is compatible with AMD64, and consequently, it is supported by Mimer SQL for Linux. Processors here are those with names like Core 2 Duo, Core 2 Quad and Core i7 series.

AMD64 (x86-64) and Intel 64 shall not be mixed up with the IA-64 architecture (Itanium), developed by Intel. Itanium is incompatible with IA-32, and thus, this version of Mimer SQL for Linux does not work on Itanium.

An AMD64 processor started in 64-bit mode can run 64-bit and 32-bit applications at the same time, but if started in 32-bit mode it cannot run 64-bit applications until it has been restarted. Please note that Mimer SQL is currently not available in 64-bit mode which implies that 64-bit programs cannot be linked with Mimer SQL, and that a larger Mimer SQL cache than 4Gb cannot be used. But still, the IA-32 based Mimer SQL for Linux runs perfectly on the platform, assuming 32-bit versions of the dynamic link libraries are installed.
