MACHINE SPECIFIC NOTES
FOR
HCL Informix Client-SDK 4.50.FC11 PRODUCT RELEASE
HCL Informix ODBC Driver Version 4.50.FC11
On Solaris Sparc 64bit
DATE: 19 Jun 2024
=================================
OS Information : Built on Solaris 11.3.
Machine Specific Notes
======================
1. This product was built on Solaris 11.3 using the following compilers
from Oracle Solaris Studio 12.3:
Sun C 5.12 SunOS_sparc December 2011
Sun C++ 5.12 SunOS_sparc December 2011
The product was built with the following 64-bit compiler flag:
"-m64"
2. Setting the environment variable LD_LIBRARY_PATH ( or LD_LIBRARY_PATH_64)
(for Bourne or Korn Shell)
LD_LIBRARY_PATH=
$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
(for C Shell)
setenv LD_LIBRARY_PATH
$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
If there are 64-bit shared object libraries (.so files)
which you want the runtime linkers ld and ild to link with your
C++ API applications, you must either add the directory paths for
these libraries to LD_LIBRARY_PATH or LD_LIBRARY_PATH_64.
Note that if you add them to LD_LIBRARY_PATH but not to
LD_LIBRARY_PATH_64 and you define LD_LIBRARY_PATH_64, they will not
be found as LD_LIBRARY_PATH is ignored when searching for 64-bit
libraries if LD_LIBRARY_PATH_64 is set.
You should either set LD_LIBRARY_PATH to all 32-bit and 64-bit
paths required by your applications and not set LD_LIBRARY_PATH_64
at all, or set LD_LIBRARY_PATH to only 32-bit paths and
LD_LIBRARY_PATH_64 to 64-bit paths.
See the Solaris man pages for ld and ild for more information
on the environment variables LD_LIBRARY_PATH and LD_LIBRARY_PATH_64.
See also the Solaris Linker and Libraries Guide.
3. The thread safe ODBC libraries are supported on this platform using
Native Solaris threads.
4. Migration of existing ODBC applications from 32 bit versions of
HCL Informix Client-SDK to HCL Informix Client-SDK 4.50.FC11.
ALL the existing 32-bit ODBC applications WILL need to be recompiled
to make them work with HCL Informix Client-SDK 4.50.FC11.
Before recompiling these existing applications, changes will be
required to be made to the application sources, if above mentioned ODBC
API and/or ODBC Datatypes are being used. Also applications should
not have any "long" and/or "unsigned long" C-Data types declared
which is being passed to any Informix ODBC APIs. Informix recommends
use of SQLINTEGER/SQLUINTEGER, SDWORD/UDWORD standard ODBC types as
defined in Informix header files.
5. Pluggable Authentication Module (PAM)
PAM functionality is supported on Solaris operating systems. The PAM is
dependent on the libpam.so library supplied by the Operating System vendor.
Use of PAM can be enabled or disabled by the system administrator. By
default, IBM IDS will use the traditional authentication mechanism in
order to avoid widespread changes required by the users.
The PAM service identifies the PAM module. This PAM module typically
resides in /usr/lib/security and its parameters are listed in
/etc/pam.conf.
6. IPv6 Support
IBM Informix Server supports Internet Protocol Version 6 (128 Bit Internet
Addresses) as well as IPv4 (32 Bit Addresses).
In order for the machine name specified in the SQLHOSTS file to resolve to
the correct IP address, the name services files on the operating system
should be correctly configured. If the machine has IPv6 address configured
and the listener thread is bound to an IPv6 address, then the name
resolution files /etc/nsswitch.conf should be configured to fetch IPv6
address. Also use the appropriate /etc/hosts setting if local machine
settings are used.
For compatibility with older IBM Informix client and server products,
assign the same hostname with both an IPv4 address and an IPv6 address.
If the listener needs to be bound to an IPv4 address and the name services
resolve the name in the order of the IPv6 address followed by IPv4 address,
then an explicit IPv4 address needs to be put in nodename field of SQLHOSTS
file. Client applications should also use the same setting.
