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 $INFORMIXDIR/extend/krakatoa/jre If J/Foundation is used, the environment variable SHLIB_PATH may need to include following paths: "/usr/lib/informix/IDS.11.50.FC7-JRE1.5/lib" "/usr/lib/informix/IDS.11.50.FC7-JRE1.5/lib/PA_RISC2.0W" "/usr/lib/informix/IDS.11.50.FC7-JRE1.5/lib/PA_RISC2.0W/native_threads" "/usr/lib/informix/IDS.11.50.FC7-JRE1.5/lib/PA_RISC2.0W/server" 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 126.96.36.199, IDS will upgrade the GSKit on your machine to version 188.8.131.52. 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: http://www.ibm.com/software/data/informix/ids/requirements/parisc.html 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 systems. - 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 60000. 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 simultaneously. 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 platform. 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 ipldd11a.sl. 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 follows: 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: http://www.hp.com/products1/unix/java/ 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 kernel. 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 follows: /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: IFMX_HPKAIO_NUM_REQ=2300; export IFMX_HPKAIO_NUM_REQ (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 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 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 installed. 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 protocol. 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 "onsocimc". 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 below: a. Rename the library to $INFORMIXDIR/lib/ibsad001.sl. b. Create $INFORMIXDIR/lib/ibsad001.sl 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. 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 iosm11a.sl. 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 libpam.sl 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 patch. 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. 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/cfwk.zip, <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 libixspw.sl. Features not Supported ====================== 1. TERMINFO 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/update.sh -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/update.sh -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". 2. All UDRs and DataBlade modules that are built in 32-bit mode must be re-compiled in 64-bit mode to work with the 64-bit server. If you have 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.
