Prepare to Install Toad IBM DB2 z/OS Components

Why Install Toad IBM DB2 z/OS Components

You must install the Toad IBM DB2 z/OS Components on each IBM DB2 for z/OS subsystem that you want to manage using Toad for IBM DB2. The z/OS components enables you to use Toad to perform the following functions on the IBM DB2 subsystem:

• Bind and rebind packages and plans
• Invoke utilities and commands within scripts that Toad for IBM DB2 advanced alters and migrations generate
• Run stand-alone IBM DB2 utilities in Toad
• Run IBM DB2 for z/OS commands from the Editor
• Remotely execute IBM DB2 for z/OS scripts
• Create, alter, or drop dataset templates
• Run DISPLAY, START and STOP commands on databases, tablespaces and indexes
• Access accurate bufferpool information
• View volumes available for defining storage
• Access information about the current threads connected to the IBM DB2 subsystem
• Assign a RACF group to a Toad Security role

Prepare to Install Toad IBM DB2 z/OS Components

After you install Toad for IBM DB2 on the client machine, install the Toad IBM DB2 z/OS Components on each IBM DB2 subsystem that you want Toad to manage. Review this section to ensure that the proper user privileges and system requirements are in place for each IBM DB2 subsystem.

Mainframe Requirements

Before installing Toad IBM DB2 z/OS Components, ensure that your mainframe meets the following minimum hardware and software requirements:

Other WLM Environment Requirements

For WLM usage, verify that the load module SORT is in the Link Pack Area (LPA) or is marked as reentrant. Due to limitations of the WLM address space starting in Program Status Word (PSW) key 8, a non-reentrant SORT load module causes an ABEND SOC4 when DSNUTILB calls SORT during utility processing.

Note: When running SYNCSORT in the WLM environment, users might receive ABEND SOC4 errors when DSNUTILB calls SYNCSORT. You can contact SYNCSORT to obtain a fix tape that contains support for IBM DB2 stored procedures. This fix applies ZAPs to the current SORT modules, and then creates a new SORT stub and aliases to a new reentrant module SYNCFNI. The documentation accompanying the tape provides instructions for applying the fix.

Privileges Required

For Installing the z/OS Component

Generally, any user can run the Toad IBM DB2 z/OS Components Installation wizard. However, one phase in the installation is to transfer installation files from the Toad client to the mainframe. If you want the wizard to automatically perform this transfer, the user ID running the wizard must have permissions to FTP the files.

After the wizard finishes its part of the installation process, the user must perform additional tasks on the mainframe to complete the z/OS components installation. The user who performs these post-wizard tasks must have the following privileges and authorities:

• SYSADM privileges in order to run SPUFI scripts and to create objects
• EXECUTE authority on all packages in the DSNAOCLI collection

Generally, a systems programmer performs the post-wizard tasks.

For Running the z/OS Component

The permhlq.JCLLIB(GRANTS) member predefines the privileges required to run the z/OS components. One of the post-wizard installation tasks is to edit and execute this member to grant these permissions to the authorization IDs you specify in the member.

IBM DB2 Subsystem Performance Requirement

To improve overall z/OS components performance on the IBM DB2 subsystem, define an index on the OWNER column in SYSIBM.SYSPLAN in the subsystem.

Catalog IBM DB2 Subsystem Before Installation

Before installing Toad IBM DB2 z/OS Components, make sure that the IBM DB2 for z/OS subsystem on which you are installing the z/OS components is cataloged on your Toad DB2 client.

To catalog IBM DB2 subsystem

Manual Transfer of the z/OS Component Installation Files

Why Manually Transfer the Installation Files?

The Toad IBM DB2 z/OS Components Installation wizard uses the default Windows FTP program to transfer the z/OS components installation files automatically from your Toad client machine to temporary datasets on the mainframe. However, you might need to transfer these files yourself for various reasons, such as:

• Windows FTP is not available.
• The wizard’s attempt to transfer the files failed.
• You selected the Do not FTP files to the mainframe option in the wizard.

Perform the Transfer Manually

The process of manually transferring the z/OS components installation files from the Toad client machine to the mainframe involves two main tasks:

• Manually allocating four temporary datasets on the mainframe
• Populating these datasets using a normal 3270 emulation product that supports TSO IND$FILE transfer

To transfer the z/OS components installation files manually

1. Using ISPF option 3.2, allocate the following datasets on the mainframe, where temphlq is the temporary high-level qualifier for the datasets:

   Dataset	Type	Allocation Specifications
   temphlq.LOADXMI	Sequential	recfm=fb,recsize=80,blksize=3120,space=(cyl,(25,15))
   temphlq.QCINST	Sequential	recfm=fb,recsize=80,blksize=3120,space=(trk,(10,5))
   temphlq.JCLLIB	PDS	recfm=fb,recsize=80,blksize=3120,space=(trk,(10,10,5))
   temphlq.QSMSG	Sequential	recfm=vb,recsize=1028,blksize=6144,space=(trk,(10,10))

   Note:temphlq.JCLLIB must be a partitioned dataset.

2. Use IND$FILE in binary mode to transfer the fileQuestDB2product_install\plugins\db2\zos\loadlib.xmi to temphlq.LOADXMI.

   Note: The QuestDB2product_install value is the directory where the Toad for DB2 client (or another Toad IBM DB2 product) is installed on your Windows machine. The temphlq value is the high-level qualifier for the temporary mainframe datasets you allocated. References to these variables are also found in steps that follow.

3. Use IND$FILE in ASCII mode to transfer the file QuestDB2product_install\plugins\db2\zos\qs.msg to temphlq.QSMSG.

4. Use IND$FILE in ASCII mode to transfer the following files from temp_local_directory\subsystem_id on your Toad client machine to the appropriate members of temphlq.JCLLIB.

   Note:temp_local_directory is the value you provided for Temporary local directory in the wizard to identify the temporary staging location for certain customized installation files on the Windows machine. The subsystem_id value is the SSID you specified in the wizard to identify the IBM DB2 subsystem on which you installing the z/OS components. The temphlq is the high-level qualifier for the temporary mainframe datasets you allocated. References to these variables are also found in steps that follow.

   Windows File Name	Dataset Member Name
   QPDSNAT	temphlq.JCLLIB(QPDSNAT)
   QCIVP	temphlq.JCLLIB(QCIVP)
   single_tasking_WLM_environment_name	temphlq.JCLLIB(single_tasking_WLM_environment_name)
   multi-tasking WLM environment_name	temphlq.JCLLIB(multi-tasking WLM environment_name)

   Note:single_tasking_WLM_environment_name and multi_tasking_ environment_name are the names of the WLM environments you specified in the wizard.

5. Use IND$FILE in ASCII mode to transfer the file temp_local_directory\subsystem_id\QCINST to temphlq.QCINST.
6. On the mainframe, run temphlq.QCINST. Use the instructions explained in the README file (located in temp_local_directory\subsystem_id or in QuestDB2product_install\plugins\db2\zos) to complete the installation process.
