Administering

This section contains information you need to perform administrative tasks while using the Data Virtualization Manager server.

Overview
As an administrator, you need to perform several administrative tasks to enable you to use IBM Data Virtualization Manager for z/OS.
Working with started task parameters
This chapter describes how to manage the started task parameters of IBM Data Virtualization Manager for z/OS.
General administrative functions
The Primary Option Menu for Data Virtualization Manager server provides access to interface facilities and administrative functions.
Rules and events
Using a rule, you can configure an automatic response to an event. For example, you can allow a critical application to download data any time, and allow a non-critical application to download data only during specific hours.
Configuring access to data sources
Configure the Data Virtualization Manager server to enable access to mainframe data sources.
SQL solution
SQL solution provides ANSI-92 SQL access to mainframe data. You can use this solution to transform mainframe artifacts into a familiar, easy-to-use relational format. With industry standard SQL access, Data Virtualization Manager makes the mainframe data available to business intelligence or analytic applications.
z/OS Connect solution
IBM Data Virtualization Manager for z/OS provides IBM z/OS Connect Enterprise Edition direct access to data with Select, Insert, Update and Delete functions using its RESTful interface. Data Virtualization Manager uses its web service data integration created via the IBM Data Virtualization Manager studio that is invoked via z/OS Connect and its RESTful interface.
Distributed transactions
Two-phase commit support is a feature of IBM Data Virtualization Manager for z/OS Enterprise Transactions. IBM Data Virtualization Manager for z/OS Enterprise Transactions support various two-phase commit protocols, with support for IBM’s z/OS Recovery Resource Management Services (RRMS). This support includes the use of the Resource Recovery Services attachment facility (RRSAF).
Running multiple servers
There are times when you might want to bring up separate Data Virtualization Manager servers, either for testing purposes or for distributing your workload.
IDF for Db2 mainframe applications
You can use the Integrated DRDA Facility (IDF) for Db2 mainframe applications so that z/OS Db2 systems can communicate with Data Virtualization Manager server to access Z and distributed data sources using Distributed Relational Database Architecture (DRDA).
Security
Advanced security is available for SQL, NoSQL, Events, and Services solutions. System programmers typically configure advanced security during Data Virtualization Manager server installation.
Performance
The Data Virtualization Manager server provides a number of features to enhance performance.
Logging and tracing server information
System information that is unique to the Data Virtualization Manager server can be recorded in Server Trace log file(s), System Management Facility (SMF) data set records, and in Data Virtualization log (DB2) tables.
Sysplex Function
Sysplex function in the IBM Data Virtualization Manager for z/OS ISPF menu helps you access different Data Virtualization Manager server, execute queries and modify various parameters across the subsystems running on different LPARs within the same Sysplex.
Monitoring
Data Virtualization Manager server provides powerful diagnostic tools that can record critical events for individual transactions. This information can be used to diagnose, debug, and correct problems.
