    IBM recommends to install the latest Developer's Bundle, Required Patch
    Bundle and Patch Bundle on your OS.

2.  The UNIX graphical tools provided with this release require 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, the environment variable SHLIB_PATH may need to be set
    to include these locations.
3.  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.

4.  The Server installation script creates the path
    /usr/lib/informix/IDS.11.50.FC7-JRE1.5 as a symbolic link, 
    it points to 

    If J/Foundation is used, the environment variable SHLIB_PATH may need to
    include following paths:

5.  IBM Informix Dynamic 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 the GSKit was previously
          installed, but is older than version, IDS will upgrade the
          GSKit on your machine to version If GSKit is not 
          installed, IDS will install GSKit in /opt/ibm/gsk7_64
          directory on your machine.

       b. The GSKit installation directory must have 50 MB of free disk space.

       c. The following packages must be installed on your system:
          PHSS_26946 or later,
          PHSS_33033 or later,
          PHCO_34275 or later

Check the following web site for the latest HP-UX system requirements 
for IBM Informix Dynamic Server:

System Configuration
1.  Kernel Parameters
    The values of the kernel parameters that were used for testing this
    product are given below. These values might need to be tuned depending
    on the application and availability of system resources. On HP-UX,
    these entries are in /stand/system.
    nfile: 5000
    semmni: 3000
    semmns: 3000
    semmnu: 1400
    shmmax: 4398046511104
    shmmni: 500
    shmseg: 500
    - The value of the kernel parameter "semmnu" should be set to at least
      the maximum number of open ipcshm connections, plus the number of
      semaphore undo structures required by other processes in the system.
      The recommended value of "semmnu" is between 2K and 4K for larger
    - The value of the kernel parameter "shmmax" should be set to the
      maximum allowable on the system. Setting "shmmax" to a high value
      will prevent the OS from creating multiple shared memory segments
      which can degrade performance.
    - This server release is built to take advantage of the Large File
      Descriptor support provided by HP-UX, which increases the number of
      simultaneous user connections per server instance from 2000 to
      To take advantage of this feature, the following kernel parameters
      might need to be increased depending on the application:
      maxfiles_lim - Maximum number of files that can be opened by a process
      nfile - Maximum number of files that can be opened system-wide.
2.  Location of Shared Memory
    The ONCONFIG variable SHMBASE should be set to the following
        SHMBASE 0x0L

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 Dynamic Server to perform recursive
    database tasks (for example, cascading deletes).
Feature Notes  (alphabetized by feature)
1.  Direct I/O 

    IBM Informix Dynamic Server does not use direct I/O by default. To enable 
    direct I/O, set the onconfig parameter DIRECT_IO to 1.

    Currently direct I/O is supported only for Veritas file systems on this

    Currently kernel asynchronous I/O (KAIO) cannot be used with direct I/O
    on this platform.

2.  Greater than 2GB Chunk & File Support
    Refer to the man page for fsadm(1M) and fsadm_hfs(1M) for how to
    enable large file support on your system. This is essential to use the
    greater than 2 GB Chunk & File Support features for cooked files.

3.  High-Availability Data Replication (HDR)

    HDR between HP PA-RISC and HP Itanium is supported for 64-bit IBM 
    Informix Dynamic Server. The server versions must match, and the binaries 
    should be compiled for each platform (UDR binaries must be compiled for 
    respective platforms).

    Example: HDR between IDS 11.50.FC1 (PA-RISC version) on HP 9000 and IDS 
    11.50.FC1 (Itanium version) installed on HP Itanium is supported as 
    long as all other HDR requirements are met.

    Please note that this configuration is not supported if the IBM Informix
    Dynamic Server on HP-UX PA-RISC uses any Java UDR or DataBlade modules 
    that are not supported on the IBM Informix Dynamic Server on HP-UX Itanium.

4.  High Performance Loader

    User-defined conversion routines must be provided in a dynamic, shared 
    library called This 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 file pointed to by
    PLCONFIG environment variable. For more details, refer the manual
    "High-Performance Loader User's Guide".

5.  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.

6.  ISMP - InstallShield Multi-Platform

    A JRE is embedded in the installation program. If you have problems with
    the embedded JRE, you can use your own. The minimum recommended JRE version
    is 1.4.2.

7. J/Foundation (Java in the Server)

    J/Foundation supports the JRE 5.0 release from IBM Corporation.
    The JRE 5.0 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

        JVPJAVAHOME  <jvphome>/jre
                where <jvphome> is $INFORMIXDIR/extend/krakatoa

    For developing Java UDRs used with J/Foundation, use JDK 5.0 which
    can be downloaded from HP's Java website:
    For IBM Informix Dynamic Server ONCONFIG settings for J/Foundation,
    refer to "onconfig.std" in $INFORMIXDIR/etc.

8.  Kernel Asynchronous I/O (KAIO)
    KAIO is DISABLED by default on this platform. To enable KAIO, set the
    environment variable KAIOON.
        KAIOON=1; export KAIOON  (for Bourne or Korn Shell)
        setenv KAIOON 1          (for C Shell)
    The following are prerequisites for using KAIO:
        a. The HP KAIO driver "asyncdsk" is installed and linked into the
        b. Ensure that the KAIO driver is up and running. Check if
           /dev/async exists. If not, follow these steps:
            1) su root
            2) If using HP hardware/OS redundancy or mirroring, create the
               async device as follows:
                  /usr/sbin/mknod /dev/async c 101 0
               Otherwise, if using IBM Informix mirroring or no hardware/OS
               mirroring, or no mirroring at all, create the async device as
                  /usr/sbin/mknod /dev/async c 101 4
            3) chmod 0666 /dev/async
            4) Make sure the following entry exists in the /etc/privgroup file
                 informix MLOCK
               After adding this entry, execute the following command

                 /sbin/rc1.d/S400set_prvgrp start

    An environment variable IFMX_HPKAIO_NUM_REQ is provided to specify the
    number of simultaneous KAIO requests that are processed by the server at
    one time. The value can be set in the range of 10 to 5000, the default
    is 1000. If the following error occurs,
        "KAIO: out of OS resources, errno = %d, pid = %d" 

    consider increasing the value of IFMX_HPKAIO_NUM_REQ.
    For example:
        (for Bourne or Korn Shell)
        setenv IFMX_HPKAIO_NUM_REQ 2300  (for C Shell)
9.  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 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 
        - 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
        - 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.
10. MQ DataBlade Module

    The MQ DataBlade module provides meachanism for data exchange between 
    IDS and queues managed by Websphere MQ.

    MQ DataBlade requires minimum version 6.0 of Websphere MQ package to be
    Note: MQ DataBlade expects Websphere MQ libraries installed in the
          default location /opt/mqm. Otherwise create symbolic links
          from /opt/mqm/lib64 to the 64-bit Websphere MQ libraries.

11. Network Protocols
    The following protocol or interfaces are supported on this platform:
        Berkeley sockets using TCP/IP
        IPC using stream pipe (implemented using Unix Domain Sockets)
        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 
               Dynamic 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 IDS via DRDA while
               supporting SQLI connections you could add a DBSERVERALIASES entry
               to ONCONFIG which corresponds to the sqlhosts file.

        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 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) if the /dev/poll pseudo driver is
    available. Please make sure that patch PHKL_30542 eventport (/dev/poll)
    pseudo driver is installed on HP-UX 11.11 if FASTPOLL is desired.

    Remote 32-bit applications and tools (example: ESQL/C, 4GL, ISQL) can
    only connect to the IBM Informix Dynamic Server using the TCP/IP
    Local 32-bit applications and tools can connect to the 64-bit server
    using either the TCP/IP sockets or the IPC stream pipe protocols.
    The protocol used for supporting MaxConnect on this platform is

12. No Age (Disable Priority Aging)

    The no aging feature that disables priority aging of CPU virtual processors 
    by the operating system can be activated by setting the noage option of the 
    VPCLASS configuration parameter for the CPU virtual processors. For example,    the following ONCONFIG entry specifies that there are 8 CPU VPs, each 
    without aging:

    VPCLASS cpu,num=8,noage

    When the noage option is used, all oninit processes will run at priority 180    with SCHED_NOAGE type scheduling. When idle, oninit processes will have the 
    priority of 154, which is the highest idle priority. This priority level 
    will prevent oninit processes from being aged when idle.

    Note: The NOAGE configuration parameter is deprecated; it is replaced by 
    the VPCLASS configuration parameter with the noage option.

    To override the default priority value for CPU VP class, set the 
    environment variable IFMX_CPUVP_PRIORITY to the desired priority, within 
    limits (154 to 190) before starting the engine.

    If IFMX_CPUVP_PRIORITY is not within the limits, the priority will be
    set to the default value of 180.
13. 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

        a. Rename the library to $INFORMIXDIR/lib/
        b. Create $INFORMIXDIR/lib/ as a symbolic link to the 
        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.

    You can backup and restore 64-bit IBM Informix Dynamic Server between 
    the HP PA-RISC and the HP Itanium platforms. You can take level-0 backup 
    on the PA-RISC platform and restore it on the Itanium platform, using 
    either the ontape or the ON-Bar utility. The server versions must match. 
    You can use this procedure to setup the HDR or RSS pair between such 
    instances. For more information on setting up high-availability clusters, 
    see the Administrator's Guide.
    Workaround for error -43399: 

    When using ON-Bar to perform backups, the following error may appear 
    in the onbar activity log file:

        "(-43399) ERROR: No response was received from the database server. 
        Aborting ON-Bar"

    To prevent this error, set the SINGLESEG_OFF environment variable 
    to 1, which changes how IDS allocates shared memory segments, and 
    then shutdown and re-start the server.

14. OnSNMP
    The SNMP agent for OnSNMP is based on SNMP Research (SNMPR).
15. Optical
    The name of the IBM Informix shared library for Optical on HP-UX is 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.

16. Pluggable Authentication Module (PAM)

    PAM functionality is supported on HPUX operating system 11.11 for 64 bit. 
    The PAM is dependent on the library supplied by the Operating 
    System vendor. This PAM library is not available in HP-UX 11.11 64 bit by 
    default. The PAM library is required, if any of the servers is configured 
    to use PAM. Please contact HP customer support to obtain the necessary PAM 

    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 

17. Processor Affinity

    The processor affinity feature, that allows the pinning of a CPU VP
    processor to a physical processor in a multi-cpu configuration, is
    supported on this platform.

18. Secure Sockets Layer

    IBM Informix Dynamic Server uses the libraries and utilities provided by
    the IBM Global Security Kit (GSKit) for Secure Sockets Layer (SSL)
    communication. The GSKit provides iKeyman utility (gsk7cmd_64, gsk7ikm_64)
    and a non-java utility (gsk7capicmd_64) for managing digital certificates
    necessary for SSL communication.

       a. Product prerequisite for iKeyman utility:
          The iKeyman utility requires the IBM Java Runtime Environment
          (JRE) or IBM Java Development Kit (JDK) version 1.3.1, 1.4.1 or
          higher with the Java Cryptography Extension (JCE) security package.

       b. Environment for iKeyman utility:
          - JAVA_HOME must be set to the JRE/JDK installation directory
          - PATH must include <JRE/JDK installation>/jre/bin
          - CLASSPATH must include <GSKit installation>/classes/,
            <GSKit installation>/classes/gsk7cls.jar and
            <JRE/JDK installation>/jre/lib/ext/ibmpkcs11.jar

       c. Before uninstalling GSKit, verify that it is not needed on your
          system. It is possible that software other than Informix Dynamic
          Server requires GSKit. Uninstalling involves running the swremove
          command to remove packages as needed. For example, the following
          command when run as root user removes a GSKit version 7 package:

          swremove gsk7bas

       d. 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.

18. Simple Password Communications Support Module

    The name of the IBM Informix shared library for Simple Password CSM on
    HP-UX is

Features not Supported
2.  DataBlade module registration using the blademgr utility with a Secure 
    Sockets Layer (SSL) connection. Use the built-in SQL SYSBldPrepare( ) 
    function to register the DataBlade module instead. 

Migrating to this 64-bit Version

1.  To migrate to this 64-bit version from previous versions of the server
    (64-bit as well as 32-bit), refer to the migration process described in
    the IBM Informix Migration Guide, Version 11.50.

    To revert from this 64-bit version to all versions other than 32-bit
    9.2x, 9.30, 9.40, 10.00 and 11.10, refer to the IBM Informix Migration 
    Guide, Version 11.50.
    To revert from 64-bit 11.50 (this server) to 32-bit 11.50:
    a. Disconnect all users from this server. The 64-bit engine should
       be in online mode.

    b. Run the following command as user informix or DBA:
            $INFORMIXDIR/etc/conv/ -32 -d

    c. Shutdown the 64-bit server.

    d. Bring up the 32-bit 11.50 server by setting your INFORMIXDIR
       environment variable to point to the 32-bit distribution.
    To revert from 64-bit 11.50 (this server) to 32-bit 11.10, 10.00, 9.40, 
    9.30 or 9.2x:
    a. Disconnect all users from this server. The 64-bit engine should be 
       in online mode.

    b. Run the following command as user informix or DBA:
            $INFORMIXDIR/etc/conv/ -32

    c. Revert to 9.2x, 9.30, 9.40, 10.00 or 11.10 32-bit by following the 
       steps described in the IBM Informix Migration Guide, Version 11.50, 
       in the section "Reverting from Dynamic Server 11.50".

    any UDRs that were developed on 32-bit, make sure that the proper size
    and alignment of the data structures are used for the UDRs to work
    correctly on 64-bit after re-compilation in 64-bit mode.
