MACHINE SPECIFIC NOTES
FOR
HCL Informix-Client SDK 4.10.FC10 PRODUCT RELEASE
HCL Informix-ESQL/C Version 4.10.FC10
On Mac OS X Server 64bit
DATE: 27 Oct 2017
=================================
OS Information : Built on Mac OS X Server 10.9.2. Certified on 10.10.
Machine Specific Notes
======================
1. This product was built on Mac OS X Server 10.9.2 with build version 13C64,
Darwin Kernel Version 13.1.0. And using the following compilers:
gcc and g++ 4.2.1 (Apple LLVM version 5.1)
2. ESQL/C support for static libraries
ESQL/C product libraries are supported as both static and shared
libraries. By default the script uses shared libraries.
To use static libraries, the 'esql' script must be invoked with the
-static option:
esql -static
To use ESQL/C shared libraries, the environment variable DYLD_LIBRARY_PATH
should be set to include $INFORMIXDIR/lib and $INFORMIXDIR/lib/esql.
During runtime of the executable, the dynamic loader will look in this
path for IBM Informix ESQL/C shared libraries.
(for Bourne or Korn Shell)
DYLD_LIBRARY_PATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql:$DYLD_LIBRARY_PATH
export DYLD_LIBRARY_PATH
(for C Shell)
setenv DYLD_LIBRARY_PATH $INFORMIXDIR/lib:$INFORMIXDIR/lib/esql:$DYLD_LIBRARY_PATH
3. ESQL/C support for thread safe libraries
The thread safe ESQL/C libraries are supported on this platform using
POSIX threads. The THREADLIB environment variable must be to POSIX:
(for Bourne or Korn Shell)
THREADLIB=POSIX
export THREADLIB
(for C Shell)
setenv THREADLIB POSIX
To build thread safe ESQL/C programs, use the following command:
esql -thread mythreadapp.ec -o mythreadapp
4. IPv6 Support
The product 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.
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.
5. Pluggable Authentication Module (PAM)
PAM functionality is supported on Mac OS X. The PAM is dependent on the
libpam.dylib 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/pam and its configurations can be set by individual
configuration files located in the /etc/pam.d directory. The required
x86_64 PAM modules are available on the OS higher than 10.9.2.
