With the Viewer you can easily and intuitively manage Tivoli Decision Support for OS/390 reports and libraries from any Windows NT, 98, Windows 2000, AIX, or SUN workstation. There is no need to use 3270 emulators. You can use the Tivoli Decision Support for OS/390 Viewer to customize and run reports and to perform all the administrative operations such as adding report libraries, creating and deleting reports, and creating and modifying SQL queries. The Viewer runs on the workstation and connects to the Tivoli Decision Support for OS/390 database on the host. All the report libraries, reports, and report data are dynamically retrieved from the host without having to save any data on the workstation. The data that the Viewer displays is always current and up to date, because the Viewer is always synchronized with the host. This manual explains all the features of the Viewer in detail. The following features are among the most important. You can navigate among report libraries and reports in the same way as you would using Windows File Manager. All the actions you can perform on graphical objects are described in the context menu for each object. Last Generation Graphical Report Capability Graphical Query Editor The Viewer provides a complete set of fully customizable graphical and tabular presentation types, including plot, pie, area, stack, and bar graphs. This powerful Viewer tool enables you to easily create and modify queries without having to manually edit the queries.

Modifying Report QMF Settings Modifying the Report QMF Settings You can change the layout of a report, for example by changing the column headings or aggregating the data in a different way, by modifying the report Query Management Facility (QMF) settings. From the Tivoli Decision Support for OS/390 Viewer window: 1. Right-click the report to display the context menu and select QMF Settings. The QMF Settings dialog is displayed. 2. Set the following fields (when applicable): Sequence No. Specifies the sequence in which the columns are displayed in the report. Type a value from 1 to 999. Blank values are not valid. If two or more columns have the same sequence number, they are displayed next to each other, following the order you specified in the query statement. This is a required field. Heading Specifies the text for the column heading in the report. Enter the new heading over the existing one. QMF Usage Defines how column data is used to produce reports. 26 Tivoli Decision Support for OS/390 : User s Guide for the Viewer

Modifying Report QMF Settings To add or change a usage code, click the field you want to set in the QMF Usage list and, from the list of usage codes that is displayed, select one of the following: (none) If no usage code is given, the column is displayed without any aggregation or summary. This usage code cannot be used with the GROUP usage code. ACROSS Displays data horizontally for one of the columns in the report. When you use ACROSS for one column, you must use GROUP for one or more of the other columns. For the remaining columns, you can use OMIT. In that case, the summary line for each group value can contain several sets of results from the columns that use aggregations. There is one set for each group of values in the column that uses ACROSS. A report can have only one column with the ACROSS usage code. BREAKn Divides the information in the report into smaller sections, to make the report easier to read and understand. There are six levels of break codes (n=1 6) that provide columns for different levels of breaks. Any change in the value of the column causes a break; subtotals are displayed for columns whose usage is one of the aggregation usages. To be able to show breaks in a meaningful way in a report, the SQL query must contain an ORDER BY clause for the column or columns for which you specify BREAKn. This usage code does not affect the display of the report in a DataView; it is significant only to Tivoli Decision Support for OS/390. GROUP Displays one line of summary data for each set of values in the column. The summary line can display only values that are the same for each member of the group, such as the value in a control column or the results of columns whose usage is an aggregation code. To present reports with GROUP usage codes in a meaningful way, the SQL query must use an ORDER BY clause for the columns for which you specify GROUP. OMIT Excludes a column and its values from the report. This usage code cannot be used with the GROUP usage code. AVERAGE Computes the average of the values in the column. The data in the column must be numeric. COUNT Computes the number of values in the column. FIRST Computes the first value in the column. LAST Computes the last value in the column. Chapter 4. Tasks 27

Modifying Report QMF Settings MAXIMUM Computes the greatest value in the column. MINIMUM Computes the smallest value in the column. SUM TCPT Computes the sum of the values in the column. The data in the column must be numeric. Computes the percentage of the column total that each value in the column represents. It replaces the data value with a calculation. The data in the column must be numeric. This usage code does not affect the display of the report in a DataView; it is significant only to Tivoli Decision Support for OS/390. Indent Specifies the number of spaces between a column and the column to its left. For the left-most column, this value corresponds to the number of spaces between the column and the left margin. You cannot modify this field. This field does not affect the display of the report in a DataView; it is significant only to Tivoli Decision Support for OS/390. Width Specifies the number of characters used for the column. Type a value from 1 to 99. This field is required.

Chapter 6. SQL Query Editor In Tivoli Decision Support for OS/390, when you request a report (DataView), the Viewer creates the SQL query to retrieve the data from the relevant database. The Viewer provides an SQL Query Editor window that enables you to view and edit the SQL query. In the SQL Query Editor window, the header, if any, of the SQL query and each clause of the SELECT statement are displayed one at a time to enable you to redefine your expressions. No syntax checking is performed on the expressions you define. You can use the SQL Query Editor to modify an existing query within a database or create a new query based on the one you are modifying. New queries can be saved as files that you store locally and can be used to replace the queries of other reports. This chapter describes how to: v Edit the query for a report v Save a query or a query file v Load a query file Editing the Query for a Report To edit the query for a report, from the Tivoli Decision Support for OS/390 Viewer window: 1.

Chapter 7. Creating and Running Batch Reports A batch report is an SQL query that is run without user intervention. Using batch reports enables you to schedule the running of the reports during off-peak times, saving valuable system resources during peak working hours. Batch reports can be run from the Batch Reports library, which is automatically created when you install the Viewer, or by using the command file that is provided with the product. You can run batch reports (that is, run the SQL queries contained in the reports) individually or you can run them all together. This chapter explains you how to: v Create a batch report v Run batch reports v View results of batch reports v Delete a batch report Compatibility with Version 1.5.1 Creating a Batch Report Batch reports that were created with the Viewer Version 1.4 are not removed when you uninstall the Viewer or install Version 1.6.0.You can still work with them. To create a batch report, from the Tivoli Decision Support for OS/390 Viewer window: 1. Right-click the report you want to run in batch and, from the context menu, select Copy. 2. Right-click the Batch Reports library and, from the context menu, select Paste to copy the report in the library. 3. If you are copying a report whose ID and database alias are the same as an existing report in the Batch Reports library, the Specify New Description dialog is displayed. Specify a New Description for the report and select OK. 57

Creating a Batch Report 4. The report is copied to the Batch Reports library for your use. Right-click the report and from the context menu select one of the following: Specify Variables Displays the Specify Query Variables dialog. Use this dialog to set the values of the variables in the query statement. This operation is required, because you are not prompted for the variables when the report is run (even if you run it at run-time). For more information about specifying query variables, see Running a Report on page 18. Properties Displays the Properties dialog. 58 Tivoli Decision Support for OS/390 : User s Guide for the Viewer You can modify: v The Description of the report, which is displayed as the report name in the Tivoli Decision Support for OS/390 Viewer window. v The Additional Description of the report. You can use a maximum of 8 characters. This field is optional. v The format in which to save the report. For more information about report formats, see Viewing Results of Running Batch Reports on page 60.

To run all batch reports at the same time, right-click the Batch Reports library and from the context menu select Run. Delete Deletes the report from the Batch Reports library. A warning message prompting you to confirm the deletion is displayed. Select OK to delete the report. To delete all batch reports at the same time, right-click the Batch Reports library and from the context menu select Delete. A warning message will prompt you to confirm the deletion. 5. Add to the Batch Reports library as many reports as you want. If you are connected to multiple databases, you can add reports that belong to different databases. Running Batch Reports Using a Command File All of the reports within the Batch Reports library are invoked together. To run the batch reports use the run_batchreport command file that is provided with the product. This file invokes the Viewer in batch mode. On Windows use run_batchreport.bat; on UNIX use run_batchreport.sh. 1. From the directory where you installed the Viewer, edit the run_batchreport file and replace the appropriate values in following line: java -classpath %CLASSPATH% com.tivoli.reporter.main.batchstartup /u userid /p pwd /h DBalias where: userid pwd DBalias The identifier of the user connected to the database The password associated with the user ID The name of the database If the batch reports you run belong to different databases, you must repeat this line for each database you use. 2. Invoke the command file from a command line or, to schedule the execution of the command file at a time that is more convenient for you, use a scheduling program. The reports are run in batch independently of whether the Viewer is running. Chapter 7. Creating and Running Batch Reports 59
