SQLXPress provides:

Database Administration

SQLXPress supports comprehensive database management facilities for installations with NonStop SQL databases, using SQL/MX tables, SQL/MP tables, or both.   Here are some examples:
  • browse SQL database definitions
  • create, alter, and drop SQL objects
  • view SQL object properties
  • browse object dependencies
  • update statistics
  • copy statistics
  • backup / restore statistics
  • duplicate SQL tables and related objects
  • manage table and index partitions 
More complex tasks like splitting a partition, creating a table, or creating a new database are supported by a powerful set of wizards. These wizards do much more than simply generate SQL statements. For example: the split partition wizard can calculate the key value required to make the split at a specified percentage of the records.

Some functions (for example, populating an index, or splitting a partition) may take a long time to perform. SQLXPress performs these as background tasks, that can be scheduled for execution by NetBatch, or the built-in job scheduling tool.



Table Management

It is often convenient to browse SQL tables, and to insert, update, delete, show DDL, compare data, compare SQL definitions, especially in a development or testing environment. This is easily accomplished using SQLXPress.




Visual Query Builder

The Visual Query Builder lets you quickly create NonStop SQL queries using familiar graphical operations such as drag and drop. You don't need to type long and complicated commands, or even remember column names - creating even the most complex of queries requires only a few keystrokes or mouse clicks.

Once a query has been built, it can be saved for use at a later time. Queries are stored in a NonStop SQL database. Each query has a security string which specifies which users can view, alter, run, and delete the query.

The Visual Query Builder supports run time parameters. Each time the query is run, the user is prompted to supply a value for each parameter in the query. Parameters are usually used in search conditions, this allows the user to select a different set of rows each time the query is run.



Reporting

A number of SQL metadata reports are included.



Execution Plan Management

SQLXPress maintains a database of execution plan snapshots.  The database contains current as well as historical plan information.

Execution plans can be added to the database for:
  • Static SQL statements in C / C++ / COBOL programs.
  • Dynamic SQL statements executed via the MXCS subsystem (OBDC / JDBC queries).
  • SQL statements stored in an MXCS Module File Cache (MFC) location.
  • Dynamic SQL queries constructed using the Visual Query Builder.
  • Dynamic SQL queries via the Query Planner.
The user can query the execution plans database to quickly identify problem plans. The Compare Plans report highlights differences between plan snapshots.  The Visual Query Tuner allows you to enter a query, and display its execution plan. 

The Query Advisor analyzes queries stored in the execution plans database and generates recommendations for improving query performance.

The user can assign a version label to plans in the execution plans database.  For example, this allows the user to assign an application version number to the set of execution plans for that version.

An execution plans database query facility allows the user to generate and run queries against the execution plans database.

The user can select plans based on a wide set of selection criteria, for example:

  • Plans for a specific application version.
  • Plans with a cost greater than a specific value.
  • Plans containing a specific SQL operator.
  • Plans using a specific type of join.
  • Plans using a specific lock mode or access mode.
  • Plans that access a specific table.

These conditions can be combined in various ways to narrow down the query results to the plans of interest.

Once the query has been run, the user can easily view the execution plans for any statement returned by the query.



Visual Query Tuner

The Visual Query Tuner is a program that is designed to help you improve the performance of NonStop SQL queries. It supports both NonStop SQL/MX and SQL/MP.

It allows you to easily perform tuning experiments and measure the effects on query performance.

The following features are supported:

  • Query snapshots that keep track of your tuning experiments.
  • Intuitive execution plan diagrams.
  • Execution statistics that capture query performance characteristics.
  • Performance charts compare performance of query snapshots.
  • Run time paramaters.
  • Defines.
  • MX and MP control statements.
  • Auto-tuner provides suggestions for improving performance.
  • View access paths for tables in the query.
  • View DDL for tables in the query.
  • View statistics for tables in the query.
  • Perform update statistics.
  • Create or drop indexes.


Module Management and Reports

SQLXPress keeps a database of relationships between programs and modules. You can browse these relationships online, or produce various reports.



DDL Statements

SQLXPress can generate DDL statements for SQL objects such as tables, views, or stored procedures.

The generated DDL can be used to re-create SQL objects. You can also use a name mapping option to create a new set of SQL objects based on the definition of existing objects, in effect a "clone schema" operation.


MXCS Subsystem Management

SQLXPress offers complete support for the configuration and monitoring of the MXCS subsystem.
Facilities include:
  • Monitor the status of services, servers, and datasources.
  • Create and destroy MXCS services.
  • Start and stop services and datasources.
  • Display the configuration of services and datasources.
  • Add, alter, and delete datasources.
  • Add, alter, and delete users.
  • Enable / disable statistics collection for a datasource.
  • Extract MXCS session and SQL statistics from EMS.
  • Display and print MXCS statistics.
  • Save MXCS statistics to an Excel spreadsheet, or a PDF file.


NonStop Server Performance Monitoring

SQLXPress supports performance monitoring fucntions that help you identify SQL queries with resource consumption problems.
Facilities include:
  • Monitor busiest SQL prcesses - identifies processes running resource-intentive queries.
  • Monitor SQL query resource usage by a process - shows the queries executed by a process (including the query text), and the system resources they use.
  • CPU resource monitoring, including CPU busy, memory usage, page faults, and dispatches.
  • Disk resource monitoring, including physical IO rate, logical IO rate, cache hit rate, and free space.
  • Disk space usage by an MX schema, or an MP catalog, a table, or an index, grouped by disk volume.
  • TMF transaction rate, and audit trail capacity.
  • Ability to suspend or terminate a busy SQL process - allows the user to kill runaway SQL queries.



Advanced SQL Scripting Language

SQLXPresss  includes MSL, an advanced SQL scripting language.

MSL supports:
  • Embedded SQL.
  • MXCI and SQLCI commands.
  • Host variables.
  • Assignment statements.
  • Program control statements like IF - THEN - ELSE, FOR, WHILE and so on.
  • Procedures and functions.
MSL scripts can be run from directly from TACL, or via  NetBatch.  Explicit SQL compilation is not required.

User Activity Auditing

SQLXPress can be configured to audit the activities of its users. Both online and batch processing activities can be audited.

Audited activities include logon, logoff, SQL statement execution, scripted MXCI commands, SQLCI commands, program launches etc.

The comprehensive reporting facilitiy provides numerous summary and detailed reports.

The Security Manager Windows-based GUI allows the security administrrator to configure the audit subsystem and run audit reports.



Role Based Access Control

SQLXPress can be configured to restrict the activities of its users. Both online and batch processing activities can be restricted.

Only authorized users can perfom specified activities.

Only authorized users can view and operate on specified SQL databases.

The Security Manager Windows-based GUI allows the security administrrator to configure the access control subsystem.



Batch Processing

SQLXPress can generate scripts to perform SQL operations in batch mode. This is most useful for long-running, or resource intensive operations that must be performed during off-peak times. The scripts can be scheduled for execution using NetBatch or a similar job scheduling tool.

International Character Set Support

SQLXPresss  includes support for :
  • Western character sets, including ISO8859-1 to ISO8859-16 and Windows code pages 1250 to 1257.
  • East Asian character sets, including Windows code pages 932 (Japanese), 936 (Simplified Chinese), 949 (Korean), and 950 (Traditional Chinese).
  • Unicode (UCS2, UTF-16, UTF-8)
  • Character set mapping. For example if a column is declared to SQL as ISO8859-1, you can instruct SQLXPress to interpret the data as ISO8859-15, or Win 1252, or even as Shift-JIS.
