MACHINE SPECIFIC NOTES
FOR
HCL Informix Client-SDK 4.50.FC10 PRODUCT RELEASE
HCL INFORMIX-ESQL/C Version 4.50.FC10
On Solaris Sparc 64bit
DATE: 08 Mar 2023
=================================
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 12.6:
Sun C 5.15 SunOS_sparc 2017/05/30
Sun C++ 5.15 SunOS_sparc 2017/05/30
The product was built with the following 64-bit compiler flag:
"-m64"
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 LD_LIBRARY_PATH
must include $INFORMIXDIR/lib and $INFORMIXDIR/lib/esql. During runtime
of the executable, the dynamic loader will look in this path for IBM
Informix ESQL/C shared libraries.
(for Bourne or Korn Shell)
LD_LIBRARY_PATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
(for C Shell)
setenv LD_LIBRARY_PATH $INFORMIXDIR/lib:$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
3. ESQL/C support for thread safe libraries
The thread safe ESQL/C libraries are supported on this platform using
Native Solaris threads. The THREADLIB environment variable must be to
SOL:
(for Bourne or Korn Shell)
export THREADLIB=SOL
(for C Shell)
setenv THREADLIB SOL
To build thread safe ESQL/C programs, use the following command:
esql -static -thread prog.ec -o prog
4. 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.
5. IPv6 Support
HCL 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 HCL 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.
