=================================
MACHINE SPECIFIC NOTES
FOR
HCL OneDB Database Server 1.0.0.1 PRODUCT RELEASE
ON Windows x64
=================================
OS Information : Built on Windows 2016 x64.. Certified on
Windows 2019.
System Requirements
===================
1. This product is built on Windows 2016 using the following compiler from
Microsoft Visual Studio 2017:
Microsoft Visual C++ 2017
2. OneDB Server uninstallation
Due to an issue in installer tool, the registry entries created by
installer will not be automatically removed after OneDB server
uninstall. The work around is to cleanup existing registry entries under
HKLM->Software->informix->DBMS.
3. Installation Prerequisite on Windows 2016 or Later Versions
User may need to temporarily turn off User Account Control(UAC) security
before you install HCL OneDB.
For information about how to create groups, add users to groups, and
turn off User Account Control, see your Windows documentation.
System Configuration
====================
1. Location of Shared Memory
The ONCONFIG variable SHMBASE is recommended to be set to the following:
SHMBASE 0x80000000L
2. Administrator permission for running server utilities
On Windows, you must run any server utility commands with administrator
permission: for example, the 'oninit -iy' command to initialize the server.
To run OneDB utility commands as an administrator, from the Start menu,
choose the OneDB server name and then choose "Run as administrator".
A command prompt with administrator permissions opens.
Feature Notes (alphabetized by feature)
=============
1. OneDB Interface for TSM
The InFormix Interface DLL for TSM is installed as
%INFORMIXDIR%\bin\libtxbsa.dll
This interface is built with TSM API version 5.3.2.
To use Tivoli Storage Manager with OneDB databases, refer to HCL OneDB
Backup and Restore Guide.
2. IPv6 Support
database server supports Internet Protocol Version 6 (128 Bit
Internet Addresses) as well as IPv4 (32 Bit Addresses).
In order for the machine name that is specified in the SQLHOSTS registry
to resolve to the correct IP address, the name services files on the
Operating System should be correctly configured.
For compatibility with earlier version of OneDB client and server
products, assign each host name 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 the IPv4 address, then an explicit IPv4 address needs to be put in the
nodename field of server registry.
3. Large Memory Addressability (LMA)
HCL OneDB LMA provides the ability to support system configurations
with greater than 4GB of RAM.
The values for the following ONCONFIG parameters are increased from
32-bit limit by LMA support:
- The maximum number of buffers in BUFFERPOOL is 2147483647.
- 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. 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 2147483647. 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 maximum value for SHMADD is 4294967296 kilobytes.
Refer to HCL OneDB Administrator's Reference manual for the information
about the related configuration parameters setting.
4. LDAP Authentication
This feature is set up and configured like the Pluggable Authentication
Module (PAM) that is used on UNIX and Linux. Use the LDAP Authentication
Support module when you want to use an LDAP server to authenticate your
system users.
The authentication module is a dynamic link library that resides in the
%INFORMIXDIR%\dbssodir\lib\security directory. The parameters of the module
are listed in the %INFORMIXDIR%\dbssodir\pam.conf file.
The source code for a fully functional LDAP Authentication Module and
samples of the required configuration files are included in the
%INFORMIXDIR%\demo\authentication directory. You can modify the code for
your specific LDAP Authentication Support module.
5. Network Protocols
The following protocol(s)/interface(s) are supported on this platform:
SOCKETS using TCP/IP
IPC using named pipe
To use SOCKETS with TCP/IP:
a. The NETTYPE entry in the ONCONFIG file and the value data of
PROTOCOL in the SQLHOSTS registry entry must contain "onsoctcp"
b. To enable an HCL OneDB Data Server Client to connect to the database
server, the NETTYPE entry in the ONCONFIG file and the value
data of PROTOCOL in the SQLHOSTS registry entry must contain
"drsoctcp"
If a CLI or JCC client wants to connect to the database server
through DRDA while supporting SQLI connections, you must add a
DBSERVERALIASES entry to the ONCONFIG file that corresponds to
the SQLHOSTS registry entry.
To use IPC (interprocess communication) with named pipe:
a. The NETTYPE entry in the ONCONFIG file and the value data of
PROTOCOL in the SQLHOSTS registry entry must contain "onipcnmp".
Remote 32-bit or 64-bit applications and tools (example: ESQL/C, 4GL, ISQL)
can only connect to the HCL OneDB 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 named pipe protocols.
6. OnLine Backup and Restore (ON-Bar)
ON-Bar uses the XBSA interface. Some of the functions invoked by ON-Bar
are in a dynamic link library supplied by third party storage management
vendors. For ON-Bar to access these functions, you must specify the library
name and location in the BAR_BSALIB_PATH parameter in the ONCONFIG file.
For example, if you are using PSM:
Set BAR_BSALIB_PATH to %INFORMIXDIR%\bin\libbsapsm.dll
For example, if you are using TSM:
Set BAR_BSALIB_PATH to %INFORMIXDIR%\bin\libtxbsa.dll
7. Simple Password Communications Support Module
The name of the HCL OneDB dynamic link library for Simple Password CSM
on Windows is libixspw.dll. This dynamic link library is installed in
%INFORMIXDIR%\bin.
8. XML User-Defined Routines
You cannot run XML UDRs at large memory segments (VX class) on this
platform.
To avoid XML UDR execution failure, configure and adjust the following
OneDB server configuration parameters in the onconfig file:
PRELOAD_DLL_FILE -
Specify the path name for a shared library file that is
pre-loaded when the server is started.
BUFFERPOOL -
Adjust the memory field to a lower value.
SHMVIRTSIZE -
Adjust it to a lower value.
