MACHINE SPECIFIC NOTES
FOR
HCL Informix Client-SDK 4.10.FC11 PRODUCT RELEASE
HCL Informix Driver Version 4.10.FC11
On AIX 6.1 64bit
DATE: 15 Mar 2018
=================================
OS Information : Built on AIX 6.1 Technology Level 4 SP 3.
Certified on AIX 7.1.
Machine Specific Notes
======================
1. This product was built on AIX 6.1 Technology Level 4 SP 3 using the
following compilers:
IBM XL C/C++ for AIX, V11.1 (5724-X13)
XL C/C++ Runtime 11.1.0.2
2. AIX patch requirement:
AIX 7.1:
September 2010 PTF for XL C for AIX, V11.1
3. For using the ODBC shared libraries, the application should be compiled
with the -brtl linker option and the LIBPATH environment variable must
be set as follows.
(for Bourne or Korn Shell)
LIBPATH=$INFORMIXDIR/lib:$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:
$LIBPATH
export LIBPATH
(for C Shell)
setenv LIBPATH $INFORMIXDIR/lib:$INFORMIXDIR/lib/cli:
$INFORMIXDIR/lib/esql:$LIBPATH
4. The thread safe ODBC libraries are supported on this platform using
POSIX threads and the applications must be compiled with xlc_r.
For using the ODBC thread shared library, the application should be
compiled with the -brtl linker option.
5. Migration of existing ODBC applications from 32 bit versions of
IBM INFORMIX-Client SDK to IBM INFORMIX-Client SDK 4.10.FC11.
ALL the existing 32-bit ODBC applications WILL need to be recompiled
to make them work with IBM INFORMIX-Client SDK 4.10.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. 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. If the machine has IPv6 address configured
and the listener thread is bound to an IPv6 address, then the name
resolution files /etc/netsvc.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.
6. Pluggable Authentication Module (PAM)
PAM functionality is supported on AIX 6.1 operating systems. The PAM is
dependent on the libpam.a 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.
