System requirements for enabling text search support

Operating system requirements

Your z/OS® operating system must meet the following requirements:

• z/OS 2.1 or later.
• The APF-authorized Language Environment® facility must be enabled for use in the database services address space (ssnmDBM1) . You must install part of the APF-authorized Language Environment in the LPA. This module is installed in SYS1.LPALIB. The remaining APF-authorized Language Environment parts are shipped in SCEERUN2, along with the 64-bit Language Environment runtime parts.
• For Db2 to use the APF-authorized Language Environment library, the Language Environment data sets SCEERUN2 and SCEERUN must be defined as authorized libraries, and the libraries must be part of the z/OS program search order for the database services address space (ssnmDBM1) started task. To meet these requirements, you can do one of the following tasks:
  • Put SCEERUN2 and SCEERUN in the LNKLST.
  • Define SCEERUN2 and SCEERUN to be APF-authorized, and place them in the STEPLIB/JOBLIB concatenation for the database services address space (ssnmDBM1) .
• To use the text search feature for Db2 for z/OS, an OMVS segment must be defined for the user ID of the database services address space (ssnmDBM1) address space started task.

Software requirements

You must install or migrate to Db2 12 (at function level 500) or later, and ensure that APAR PH35720 is applied on the system.

Also, you must install the following components of Db2 Accessories Suite for z/OS, Version 4.1.0 or later:

• IBM® International Components for Unicode (ICU) for Db2 for z/OS
• IBM Text Search for Db2 for z/OS

To download the most current version of the text search server, see IBM Text Search for Db2 for z/OS downloads.
