System requirements for installing a text search server

Before you install IBM® Text Search for Db2 for z/OS®, make sure that your system meets all of the hardware, software, and operating system requirements.

Hardware requirements

You can install a text search server on a supported Linux®, Linux on IBM Z®, or Windows server. Db2 for z/OS uses a TCP/IP connection to communicate with the text search server.

Make sure that your server meets the following minimum hardware requirements.

For Intel Linux or Windows servers:
  • Two dual-core 2.66 GHz processors
  • 4 GB RAM
For Linux on IBM Z servers:
  • Two processors
  • 8 GB RAM

You need enough disk space to hold four times the original text size multiplied by the number of text search indexes. Each text column in a Db2 table has a corresponding text search index on the text search server. For example, if a text search server supports five indexes each with 1 million rows of 1 KB text size, the required disk space needed is about 20 GB.

Designate that this hardware is used exclusively by the text search server.

Operating system requirements for IBM Text Search for Db2 for z/OS

You can install a text search server for IBM Text Search for Db2 for z/OS on the following operating systems:
  • 64-bit Red Hat Enterprise Linux, Version 5 with the latest update
  • 64-bit SUSE Linux Enterprise 10

  • 64-bit Red Hat Linux on IBM Z, Version 5 with the latest update
  • 64-bit Windows Server with the latest service pack
Note: If you install more than one text search server, for fail over support you must install all of the servers on the same type of hardware, and make sure that each server uses the same operating system.
