HCL OneDB ODBC Driver Version 1.0.1.1
On Linux Intel 64bit
DATE: 30 Dec 2021
=================================
OS Information : Built on Red Hat Enterprise Linux ES release 7.4 (Maipo)
Certified on SUSE SLES 12.3 and 15,
Ubuntu Server Edition 16.04 LTS and 17.10.
Machine Specific Notes
======================
1. This product was built on Red Hat Enterprise Linux ES release 7.4
(Kernel: 3.10.0-693, Glibc: 2.17) for x86_64 compatible processors.
The following compilers were used:
gcc and g++ compiler 4.8.5 20150623 (Red Hat 4.8.5-16)
Installing the product on Ubuntu or Debian requires RPM to be installed
and initialized. After RPM installed, use the following commands to
initialize RPM:
mkdir -p /var/lib/rpm
rpm --initdb
The bc utility is required by the product installer, and needs to be
installed on Ubuntu.
2. For shared library support, environment variable LD_LIBRARY_PATH
needs to be set to include the $INFORMIXDIR/lib/cli directories
where HCL OneDB ODBC shared libraries are installed.
(for C Shell)
setenv LD_LIBRARY_PATH $INFORMIXDIR/lib:$INFORMIXDIR/lib/cli:
$INFORMIXDIR/lib/esql:$LD_LIBRARY_PATH
(for Bourne or Korn Shell)
LD_LIBRARY_PATH=$INFORMIXDIR/lib/cli:$INFORMIXDIR/lib/esql:
$LD_LIBRARY_PATH
export LD_LIBRARY_PATH
3. The thread safe ODBC libraries are supported on this platform using POSIX
threads. Make sure that you set the THREADLIB environment variable to
"POSIX" before linking your ODBC program using the esql script.
4. Pluggable Authentication Module (PAM)
PAM functionality is supported on Linux 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, HCL OneDB 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 /lib/security and its parameters are listed in /etc/pam.d.
The pam.conf file is ignored on Linux, if the /etc/pam.d directory is
present.
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 HCL OneDB 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.
