Product publications

To access the Tivoli Workload Scheduler documentation, see the online information center at: http://publib.boulder.ibm.com/infocenter/tivihelp/v3r1/index.jsp?topic=/com.ibm.tivoli.itws.doc_8.4.1/welcome.htm

This section lists the operating systems supported at the time of the general availability of the product. To see an up-to-date list of the supported operating systems that were certified after the general availability, use the following link: http://www.ibm.com/software/sysmgmt/products/support/Tivoli_Supported_Platforms.html.

Table 2 identifies the operating systems that are supported by the engine (where the support is not full, details are supplied in the notes).

The following abbreviations are used in the table (and elsewhere on this page):

1. InstallShield installation on Linux operating systems needs the bc utility to be installed. For further information see http://community.installshield.com/archive.
2. The Job Scheduling Console is included in this table to aid you for planning purposes. Its hardware and software requirements are documented in the the Tivoli Workload Scheduler: Job Scheduling Console User's Guide.
3. The Job Scheduling Console is not supported on SuSe Linux Enterprise Server 10.
4. On Red Hat Enterprise Linux 3.0 DB2® 9.1 is not supported. On these systems, you need to install DB2 8.2 manually before running the Tivoli Workload Scheduler installation.

Supported operating systems for the prerequisite database

Tivoli Workload Scheduler requires the use of either the DB2 or the Oracle relational database. The supported operating systems are as follows:

Supported operating systems for the prerequisite version of DB2

Tivoli Workload Scheduler requires version 8.2 (or 8.1 with fix pack 7) or later of DB2.

Bundled DB2

Tivoli Workload Scheduler is supplied with a version of the DB2 server and client for the supported operating systems. This version can either be installed by you separately before the product installation, or automatically as part of the product installation. Refer to Table 5 for details on the DB2 bundled versions for each of the supported operating systems, and the operating systems patch levels required.

Note:

The bundled version of DB2 is provided solely for use with Tivoli Workload Scheduler (see the product license for details).

To determine the supported operating systems for a version of DB2 other than the bundled version, see the DB2 documentation.

Supported operating systems for the prerequisite version of Oracle

Tivoli Workload Scheduler requires the use of the following versions of Oracle with the partitioning option installed:

• Oracle Database 9i Release 2 - Enterprise Edition (9.2.0.x) or later
• Oracle Database 10g Release 2 - Enterprise Edition (10.2.0.x) or later.

The Oracle database software is not supplied with Tivoli Workload Scheduler. You must use your own version of the Oracle database software.

For a complete list of supported operating systems for Oracle see the Oracle documentation.

Supported operating systems for the bundled application server

Tivoli Workload Scheduler uses the Embedded Version of WebSphere™ Application Server, version 6.1. All operating systems supported by Tivoli Workload Scheduler are supported by the application server. It is installed automatically. In the information relating to hardware and memory requirements in this document, the application server is treated as part of Tivoli Workload Scheduler, and its requirements are not listed separately.

Table 4 lists the software requirements for each supported operating system.

Software requirements for the bundled version of DB2

Table 5 lists the software requirements for the bundled version of DB2. For specific operating system limitations see ***

1. On Red Hat Enterprise Linux 3.0 DB2 9.1 is not supported. On these systems, you need to install DB2 8.2 manually before running the Tivoli Workload Scheduler installation.
2. DB2 9.1 Fix Pack 3 is supported on HP-UX 11i v3 for Itanium operating systems only. For Pa-RISC, DB2 9.1 Fix Pack 1 is required.

Supported LDAP Servers

The following is a list of the LDAP servers supported by Tivoli Workload Scheduler:

• IBM Tivoli Directory Server 5.1, 5.2 or 6.0
• IBM z/OS® Security Server 1.4, 1.5 or 1.6
• IBM z/OS.e Security Server 1.4, 1.5 or 1.6
• Windows Active Directory 2003
• Sun ONE DS

This section describes the hardware requirements for Tivoli Workload Scheduler and includes information such as machine types and disk space.

Note: Space requirements for language packs and license agreement files is included.

Permanent disk space requirements when installing the product

Table 6 summarizes the minimum disk space requirements when installing the Tivoli Workload Scheduler components and features on supported operating systems.

1. These figures include the presence of the base structure for Tivoli Workload Scheduler in the DB2 database
2. These figures do not include the presence of the base structure for Tivoli Workload Scheduler in the DB2 database, because this is indicated in either the entry for the MDM with a DB2 server, or the entry for the standalone DB2. These figures can be used to exclude DB2 if you are using an Oracle database.
3. The space listed in this column is divided as follows:
   • 200 megabytes in the DB2 installation path
   • 20 megabytes in the Data tablespace path
   • 20 megabytes in the Reports tablespace path

Permanent disk space requirements when upgrading the product including backup

Table 7 summarizes the minimum disk space requirements when upgrading the Tivoli Workload Scheduler components and features including backup on supported operating systems.

Space requirements for operating Tivoli Workload Scheduler

Table 6 and Table 7 do not include the space required to operate Tivoli Workload Scheduler. For this you must consider the additional space required for the database data, the Symphony file, the log files, temporary files that are placed on the local hard drive, and files associated with the jobs managed by Tivoli Workload Scheduler. You should also consider the archive period for the Symphony file and the retention period for log files.

The space required is very subjective and depends on how you use Tivoli Workload Scheduler. If you are already a user of the product, you will have an idea of how much space it currently occupies. However, you should bear in mind that each version of the system uses more disk space than the previous one. If you are a new user you will probably set up a test system to help you grow familiar with the product and you should be able to scale up the operating space requirements of the test system to give you an indication of how much space you will be using in a fully functional live system.

Temporary space requirements

Table 6 and Table 7 do not include the space requirements for the temporary installation files, details of which are given in Table 8:

Virtual memory space requirements

Neither Table 6 nor Table 7 nor Table 8 include the requirements for the virtual memory file (sometimes called page file or swap space). The installation requires at least 512 MB of virtual memory on any operating system.

Oracle space requirements

For information about Oracle permanent and temporary file space requirements see the Oracle documentation. In this case you should discount the DB2 space requiremnts in the tables above.

Memory requirements

Table 9 summarizes the memory requirements for the various components, on all operating systems:
