Sybase’s Goals

Reduce cost of ownership through system management features

Build tools to support ASE product features and operational requirements

Support system management vendors and partners in bringing new products to market

Provide tools for customers who develop management tools

6

Commitment to Improvement

We are investing in products such as the ASE Plug-in, DBXray and Installer

We are working with partners and vendors to help provide and improve their tools

We are working with the Sybase community to make additional tools available> E.g., through the SDN CodeXchange forums

We want YOUR ideas and input!

7

Reducing Cost of Ownership

• Improve ease of use For the ASE and management tools

• Reduce complexityTo make powerful ASE features more accessible

and easy to understand• Leverage existing skills and resources

So that you can spend your time on important tasks

8

The ASE is already one of the easiest databases to manage

We are adding new features and tools to make it easier> Job Scheduler> Self-management features> DBXray

We welcome your input on improvements in this area

Improving Ease of Use

9

Still Farther to Go…

Some areas we will be working on: Enterprise features ASE Plug-in improvements

> Support for common tasks such as security management, backup management and troubleshooting

Data movement Integration with Replication Server Index tuning Space management

SQL Expert> Identifies poorly performing queries> Provides automated SQL tuning recommendations

13

New System Management Features: ASE 12.5

ASE Replicator and Replicator Manager> New “light weight” data replicator

Migration Tool> Supports migration to larger page size> Support for cross-platform migration

SQL Advantage (back by popular demand!) SNMP Subagent

> AgentX protocol subagent> Available from Sybase Developer Network

14

New Features: 12.5.0.3 and Beyond…

ASE Monitoring Tables> SQL access to process-, object- and resource-level

performance monitoring data• DBXray

> Graphical performance monitor (at last!)> State of the art detailed “real-time” diagnostic information

ASE Job Scheduler (ASE 12.5.1)> Support for scheduled backups, DBCC, update stats,

reports, etc.> Pre-defined templates for common tasks

Improved Installation: InstallShield> GUI, character mode and scripted installation• For all release types

15

ASE Plugin to Sybase Central

Complete support for managing your ASE

Fully rewritten in Java for ASE 12.5 release

Runs on all ASE Platforms Supports new ASE features

including EJB Server, HA, ASE Replicator, expanded column and page sizes, multiple tempdb

Future features will improve usability and enterprise administration

• Section 508 Compliant

16

ASE Plugin: New in 12.5.1

Table data view Job Scheduler Logging of SQL for ASE Plugin commands Non-ASE proxy data sources Portable database support Disk Resize Improved process and lock monitoring Section 508 accessibility compliance

17

ASE Plugin: ExamplesTableDataView

SQL Log

Server Shutdown Wizard

18

ASE Plugin: Directions

Increased information about sessions > Resource usage, SQL Text, blocking

SQL pre-view and editing of commands Access to ASE errorlog Improved and new wizards Performance improvements

19

DDLGen Utility

Introduced in ASE 12.5 Command line utility for generating DDL for an

existing database or individual objects> Tables, indexes, triggers, etc.

Available on all platforms Also used by Sybase Central ASE Plugin to

generate DDL for objects Will continue to support new object types in

future releases

20

ASE Monitoring Tables

Available in ASE 12.5.0.3 Release and later Full SQL language support for access to detailed

monitoring data Tables include data caches, locks, SQL statement

statistics, SQL Text, system and process wait states, device and network IO….

Filter, join, analyze performance data:> E.g., Process wait time, data cache object usage

Access performance data from remote servers via CIS

Useful to DBA’s and system management vendors

21

Monitoring Tables: ExampleShow object withLargest # of pages inDefault data cache

Show all objectsin default data cache

22

Monitoring Tables: Example

Show the currently executing query and user with the greatest amount of CPU time

select s.SPID, suser_name(p.suid), s.CpuSeconds, t.LineNumber, t.SQLTextfrom monProcessStatement s, monProcessSQLText t, sysprocesses pwhere s.CpuSeconds=(select max(CpuSeconds) from monProcessStatement)and s.SPID = t.SPIDand p.SPID = s.SPID

23

Job Scheduler

Available in ASE 12.5.1 Create jobs and execute them according to a schedule Perform backups, DBCC’s, update statistics, reorgs,

reports, etc. on a scheduled – hands-off - basis Job results are logged to allow problem analysis Job and Schedule definitions can be shared by multiple

users Supports job definition through:

> GUI Interface in Sybase Central> SQL Language interface

24

Job Scheduler: Example

Create Scheduled Jobs

Review Job Status

Manage JobProperties

25

Self-Management: ob Scheduler Templates

Make life easier by reducing steps to schedule a task

Automate common management and configuration tasks

Shortcuts for defining common jobs

Jobs execute on threshold or time basis

26

Self-Management: ob Scheduler Templates

Templates planned for ASE 12.5.1> Database backup> Dump transaction> Update statistics> Delete statistics> Reorg rebuild table or index> Reorg reclaim space> Reconfigure

User connectionsMetadata cacheNumber of locks

27

Migration Tool

Introduced in ASE 12.5.0.1 release> ASE 12.5 introduced larger page sizes

Use to move existing data from an ASE using 2K page size to one using larger page size

> Supports cross-platform move in 12.5.0.3 Automates schema and data movement

processes> Generates and applies database DDL> Copies data to target server using CIS

Easier than recreating database and using BCP

28

Migration Tool•Migrate data between ASE servers•Database schema and data migration•Graphical selection of source and target servers and objects and migration status•Used to increase page size or move databases

29

PowerTransfer

Data migration utility Extension (Plugin) to PowerDesigner’s Physical

Architect Module Based on PowerDesigner 9.5.1

Launched by PowerDesigner, and uses Data Model to identify tables to be copied

Assumes that Schema has been pushed from source DBMS to ASE

Supports importing data from MS SQL Server, Oracle, DB2, ASE 12.5 and earlier

30

PowerTransfer: Example

Server Login

TableSelection

31

SNMP Subagent for ASE

Available in ASE 12.5.0.2 for Apple OS X> Available on all platforms soon

Uses Java AgentX implementation Downloadable opensource from SDN SNMP Version 2c support Support for standard MIBS:

> RDBMS MIB RFC 1697> Network Service MIB RFC 2248

Implementation of Sybase Proprietary MIB Server monitoring and trap notification for server state

changes. Trap notification for ASE errors through sp_errornotify Monitoring of Sybase ASE and Open Servers.
