Minimum requirements

Check that your system meets the following hardware, software, database, and user account requirements.

Hardware

IBM recommends that you run the InterChange Server on a dedicated system. The system should have restricted access to maintain security.

The following hardware requirements are suggested minimum requirements. However, the actual hardware requirements for your system may be greater, depending on the complexity of your specific environment, throughput, and data object size. Also, the following information is for the InterChange Server system only. If you choose to run other applications on the same system, make appropriate adjustments.

Component Minimum Required
Processor
Pentium III @ 1 GHz
Memory
512 MB
Disk space: InterChange Server and supporting software
20 GB
Disk space: InterChange Server databases
  • Repository 300-500 MB
  • Rollback 500 MB
  • Temporary 500 MB

Additional High-Availability Requirements
  • Microsoft certified cluster machine
  • Shared disk subsystem with RAID

If you are installing InterChange Server in a high-availability environment, each machine in the cluster must also meet the following requirements:

&box. Microsoft-certified cluster machine--Each machine in the cluster must be a Microsoft certified cluster machine. To view a list of Microsoft certified cluster machines, go to http://www.microsoft.com/hcl/default.asp, select Cluster, then click Go.
&box. Shared disk subsystem with RAID (redundant arrays of independent disks)--Both systems in the cluster must share a disk subsystem. For best performance, the level of redundancy is RAID 0, but RAID 1 is also acceptable.

Software

The InterChange Server system requires software produced by other vendors for its runtime and development environment.

&box. IBM Java Development Kit (JDK) 1.4.2 component: Java compiler (optional, but necessary for compiling customer-generated maps and collaborations). Installed automatically by the ICS installer.

User accounts

Different system users and levels of access permissions are required for security reasons. Make sure your environment has at least the following user privileges:


User account Description
&box. Domain User
The Domain user is a single user who installs and configures the InterChange Server system and supporting software on both servers in a cluster.
&box. System administrator
The System administrator creates the IBM WebSphere business integration system administrator account on the local machine.
&box. InterChange Server administrator The ICS administrator installs and configures the ICS system and supporting software.
&box. Database administrator (DBA)
The DBA creates the databases, data sources, and InterChange Server database login account that the WebSphere business integration system uses.
&box. InterChange Server database login account: wicsadmin
Use InterChange Server login account to access the repository and cross-reference databases to create and update tables.
&box. Application administrator
The application administrator configures and develops applications, and configures the application to work with its associated connector. IBM recommends you use the highest level of access to the application.

Database requirements

InterChange Server is certified for use with Oracle Server 8.1.7.4 and 9.2.0.4 (9i), IBM DB2 version 8.1, and Microsoft SQL Server 2000 with service pack 3.

Oracle Server

Check that the Oracle Server meets the following criteria:

&box. Tablespace with data file names defined. IBM suggests CWROLLBACK, CWTEMP, and wicsrepos.
&box. At least 300 MB of disk space for the temp and rollback data files available.
&box. Rollback segments defined. IBM suggests CW_RBS1, CW_RBS2, CW_RBS3, CW_RBS4, and CW_RBS5.
&box. System and environment variables set.
&box. IBM suggests wicsrepos for both the database name and the SID (System ID) of the database.
&box. initcwld.ora parameter file with open_cursors parameter set to at least 500, and the rollback segments defined.
&box. Listener.ora file defined with SID_NAME = wicsrepos.
&box. Database name with the network protocol defined. IBM suggests wisrepos.
&box. wicsadmin user with resource and DBA (database administrator) privileges.

SQL Server

&box. wicsadmin user with table creation privileges created
&box. 50 MB of disk space for data files available for the repository database (wicsrepos)
&box. 40 user connections configured
&box. 50 MB of disk space available for the mapping tables (optional)
&box. Logging configured for Truncate Log on Checkpoint

DB2 Server

Check that the DB2 Server meets the following criteria:

&box. wicsadmin user with table creation privileges created
&box. 50 MB of disk space for data files available for the repository database (icsrepos)
&box. The maxappls and maxagents parameters configured with a minimum of 50 user connections each
&box. 50 MB of disk space available for the mapping tables (optional)
&box. Maximum application heap size configured to be at least 2048
