MACHINE SPECIFIC NOTES
FOR
IBM Informix Database Server 11.70.FC6 PRODUCT RELEASE
ON Solaris x64
DATE: 27 Sep 2012
=================================
OS Information : Built on Solaris 10 update 6 on x64.
Certified on Solaris 11.
System Requirements
===================
1. This product was built and tested on Solaris 10 for Intel using the
following compilers from Oracle Solaris Studio 12:
Sun C 5.9 Patch 124868-08 2008/11/25
Sun C++ 5.9 Patch 124864-11 2009/03/10
2. IBM Informix Database Server is supported to work with and without Zones
on Solaris 10. Read the following document for more information, this
would be also applicable to Solaris AMD/Opteron system:
ftp://ftp.software.ibm.com/software/data/informix/ids/IDS-SunSPARC-reqs.pdf
3. The UNIX graphical tools provided with this release require 64-bit
X Windows System X11R6 and Motif 2.1 or later runtime libraries.
If these tools cannot find the location of the X and Motif shared
libraries, set the environment variable LD_LIBRARY_PATH to include
these locations: /usr/openwin/lib/amd64 and /usr/dt/lib/amd64.
4. The High Performance Loader utilities, onpload and ipload, require a
minimum of 35 MB of memory and 70 MB of swap space in order to run.
5. IBM Informix Database Server uses the libraries and utilities provided by
the IBM Global Security Kit (GSKit) for data encryption and Secure Sockets
Layer (SSL) communication. The GSKit is bundled with the server and will
be installed on your machine as part of the server installation process.
Here are more details on the GSKit:
a. The GSKit is also bundled with other IBM products and might
already be present on your machine. If GSKit8 is not
installed, Informix server will install GSKit in /opt/ibm/gsk8_64
directory on your machine.
b. The GSKit installation directory must have 40 MB of free disk space.

System Configuration
====================
1. System V IPC Parameters
On Solaris 10, all System V IPC facilities are either automatically
configured or can be controlled by resource controls.
The resource controls have the following default values on Solaris 10:
process.max-sem-nsems 512
project.max-sem-ids 128
project.max-shm-memory 1/4 of physical memory
project.max-shm-ids 128
Check project.max-shm-memory on your system, IBM recommend the value
of 4398046511104 for the IBM Informix Database Server.
On systems that have zones enabled, zone-wide resource controls are
specified in the zone configuration.
Refer to rctladm(1m) man page for more information about available
resource controls.
Examples:
a. To display the current value of project.max-shm-memory set to the
project and system wide, where Informix server is running under the
default project, run this command:
# prctl -n project.max-shm-memory -i project default
b. To display the values of all the resource controls for a specific
Informix server process, run this command:
# prctl <oninit pid>
c. To set the value of project.max-shm-memory for the project default
to 4 TB without restarting the system, run this command:
# prctl -n project.max-shm-memory -r -v 4tb -i project default
d. To perform the same action as in example c, but instead use
the projmod command to modify the attribute value for
project.max-shm-memory in /etc/project the local source of
project information file, run this command:
# projmod -a -K 'project.max-shm-memory=(priv,4TB,deny)' default
2. Location of Shared Memory
The ONCONFIG variable SHMBASE should be set to the following:
SHMBASE 0x10A000000L
3. Environment Variables
It is recommended that the environment variable INFORMIXSTACKSIZE be
set to 128 (the default is 64) if the application involves operations
which would require the IBM Informix Database Server to perform recursive
database tasks (for example, cascading deletes).
Feature Notes (alphabetized by feature)
=============
1. High Performance Loader
User-defined conversion routines for the High Performance Loader must be
provided in a dynamic, shared library called ipldd11a.so. This shared
library is installed in the $INFORMIXDIR/lib directory. You can set the
location of this file with the HPL_DYNAMIC_LIB_PATH configuration parameter
in the file pointed to by PLCONFIG environment variable. For more details
see the "High-Performance Loader User's Guide".
To create a 64-bit shared library, the flags "-m64" can be used
to convey to the compiler that a 64-bit object is to be generated.
Onpload will use shared memory during its execution. It will allocate
memory beyond the address for the server, leaving room for server shared
memory expansion.
2. 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
addresss. 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.
3. J/Foundation (Java in the Server)
J/Foundation supports the JRE 6.0 release from Oracle, which uses the
Solaris native threads based Java Virtual Machine.
The JRE 6.0 is available under $INFORMIXDIR/extend/krakatoa/jre and
should be used with J/Foundation.
To use this JRE, set the value of the ONCONFIG variable JVPJAVAHOME as
follows:
JVPJAVAHOME <jvphome>/jre
where <jvphome> is $INFORMIXDIR/extend/krakatoa
For IBM Informix Database Server ONCONFIG settings for J/Foundation,
refer to "onconfig.std" in $INFORMIXDIR/etc.
4. Large Memory Addressability (LMA)
IBM Informix LMA provides the ability to support system configurations
with greater than 4GB of RAM. Most UNIX systems are limited to 4GB of
RAM based on the memory addressing limitations of 32-bit architectures.
The values for the following ONCONFIG parameters are increased from
32-bit to 64-bit platform by LMA support:
- The maximum number of buffers in BUFFERPOOL is 536870912.
- The maximum of LRU queues for lrus field in BUFFERPOOL is 512.
- The DS_TOTAL_MEMORY, which is the total memory available for
decision support memory, is only limited by the amount of virtual
memory available (2^40)/2 MB. The sort memory comes out of the
DS_TOTAL_MEMORY memory and hence there is no explicit limit on the
amount of sort memory.
- The read ahead parameter RA_PAGES is only limited by the number of
buffers and therefore can be any value less than 536870912. The
"chunk" write algorithm is not dependent on the amount of buffers or
shared memory and can write as many pages in a single I/O as possible.
- The maximum size of any shared memory segment is 4398046511104 bytes.
- The value for SHMADD is 4294967296 kilobytes.
Please refer to IBM Informix Administrator's Reference manual for the
information about the related configuration parameters setting.
5. MQ Messaging Database Extension
The MQ extension provides mechanism for data exchange between
Informix server and queues managed by Websphere MQ.
6. Network Protocols
The following protocol(s)/interface(s) are supported on this platform:
TLI using TCP/IP
SOCKETS using TCP/IP
IPC using stream pipe
To use TLI with TCP/IP:
a. NETTYPE in the ONCONFIG file and the nettype field in the
sqlhosts file entry must contain "ontlitcp".
b. To enable an IBM Data Server Client to connect to Informix
Database Server, NETTYPE in the ONCONFIG file and the value data
of protocol in the sqlhosts file entry must contain "drtlitcp"
To use SOCKETS with TCP/IP:
a. NETTYPE in the ONCONFIG file and the nettype field in the
sqlhosts file entry must contain "onsoctcp".
b. To enable an IBM Data Server Client to connect to Informix
Database Server, NETTYPE in the ONCONFIG file and the value data
of protocol in the sqlhosts file entry must contain "drsoctcp"
If a CLI or JCC client wants to connect to Informix server via DRDA while supporting SQLI connections you could add a DBSERVERALIASES entry to
ONCONFIG which corresponds to the sqlhosts file.
When using either TLI or SOCKETS, set the "connections" field in
the ONCONFIG NETTYPE parameter and the kernel driver ndd parameter
"tcp_conn_req_max_q" to the maximum number of expected concurrent
connections.
If the "tcp_conn_req_max_q" is set too low, you will see a client
error with sqlcode = -908 and isamcode = 13. If the NETTYPE
"connections" field is set too low, you will see a server
listener-thread error with err = -25571.
To use IPC (interprocess communication) with stream pipe:
a. NETTYPE in the ONCONFIG file and the nettype field in the
sqlhosts file entry must contain "onipcstr".
Fast poll is supported with all TCP/IP and stream pipe interfaces.
FASTPOLL in the ONCONFIG file can be set to 0 to disable the fast poll.
By default the fast poll is enabled (value is 1).
Remote 32-bit applications and tools (example: ESQL/C, 4GL, ISQL) can
only connect to the IBM Informix Database Server using the TCP/IP
protocol.
Local 32-bit applications and tools can connect to the 64-bit server using
either the TCP/IP or the IPC stream pipe protocols.
The protocol used for supporting MaxConnect on this platform is
"ontliimc".
7. OnLine Backup and Restore (ON-Bar)
Some of the functions invoked by ON-Bar are in a shared library supplied
by third party storage management vendors. For ON-Bar to access these
functions, the library must be installed in one of the three ways
noted below.
a. Rename the library to $INFORMIXDIR/lib/ibsad001.so.
b. Create $INFORMIXDIR/lib/ibsad001.so as a symbolic link to the
library.
c. Set the BAR_BSALIB_PATH parameter in $INFORMIXDIR/etc/$ONCONFIG
to the full pathname of the library.
This shared library must be compiled in 64-bit mode.
Informix Interface for Tivoli Storage Manager (TSM) is supported on this
platform. The interface is built with TSM API version 5.3.4.
8. Optical
The name of the IBM Informix shared library for Optical on Solaris is
iosm11a.so. This library must be located in $INFORMIXDIR/lib (or must have
a link provided in $INFORMIXDIR/lib).
Refer to the "Optical Subsystem Guide" for more information about
enabling optical functionality.
9. Pluggable Authentication Module (PAM)
PAM functionality is supported on Solaris (64bit) operating system.
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 Inforix server will use the traditional authentication
mechanism in order to avoid wide spread 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.
10. Secure Sockets Layer
IBM Informix Database Server uses the libraries and utilities provided by
the IBM Global Security Kit (GSKit) for Secure Sockets Layer (SSL)
communication.
a. Before uninstalling GSKit, verify that it is not needed on your
system. It is possible that software other than Informix Database
Server requires GSKit. Uninstalling entails removing the GSKit
packages with the pkgrm command-line tool
As root user run the pkgrm command to remove each package as
needed. For example, the following command removes a GSKit
SSL and GSKit Crypt packages:
pkgrm gsk8ssl64 gsk8cry64
b. If you want to restore Secure Sockets Layer capability after you
have uninstalled GSKit, see the readme file in $INFORMIXDIR/gskit
for how to install GSKit.
11. Simple Password Communications Support Module
The name of the IBM Informix shared library for Simple Password CSM
on Solaris is libixspw.so.
