Shared Statement CacheShared Statement Cache

• Query plans shared between connections

• Big benefits for sites with lots of users and only one or two applications

IDS

Fuzzy CheckpointsFuzzy Checkpoints

• Not all dirty pages are flushed

• Write-ahead logging ensures consistency in a fast recovery

• Shortens checkpoint duration

• Allows larger buffer pools without impacting OLTP performance

04/08/23


Performance – Dynamic LoggingPerformance – Dynamic Logging

• Eliminates server hangs due to long transactions

• New onconfig parameter DYNAMIC_LOGs– Server can automatically

insert and use a new log file– DBA can also add new logs

without quiescing the system

• New logs are usable immediately– No need to archive rootdbs

New log

04/08/23


Dynamic Lock ManagementDynamic Lock Management

• IDS will add locks on the fly if lock table overflows

• Prevents application hangs

• Message written – DBA can adjust lock table size later

04/08/23


Performance - MaxConnectPerformance - MaxConnect

• Multiplex database connections

• NO CHANGE required for existing applications

• Increase scalability

• Reduce response times

Enterprise ReplicationEnterprise Replication• Improved Performance

– DataSync dynamic parallelism– Stable queue management improvements– Partial update row support

• Extended Support– SBLOB support– Opaque data type support

• Miscellaneous– Support for serial primary keys– Inplace alter for CRCOLS– Replicate Sets

Server Studio Java EditionServer Studio Java Edition

• Database Object Explorer

• SQL Editor • Table Editor

• Other tools are available from AGS, including a stored procedure debugger.

ExtensibilityExtensibility• User-defined types

(UDT’s)– Distinct, opaque

• Table/type inheritance• Functional indexes• R-Tree indexes• Smart large objects

• Complex types– Row, set, multiset, list

• Polymorphism• User-defined routines

(UDR’s)• User-defined aggregates• Primary/secondary

access methods

Benefit:Benefit: The database adapts to suit The database adapts to suit youryour businessbusiness

04/08/23


UDT’s and UDR’sUDT’s and UDR’s

• User-Defined Data Types (UDT’s)– define your own data structures– e.g. a parts explosion stays a parts explosion– the database accommodates the “shape” of the data

• User-Defined Routines (UDR’s)– define your own operations– a single statement replaces a procedure– put business logic in the database

04/08/23


A Trivial but Powerful ExampleA Trivial but Powerful ExampleCreate a user-defined function…. create function area (radius real) returning real; return radius * radius * 22 /7 ; end function;Then you can… select id, area(radius_col) as the_area from mytable where area(radius_col) < :QArea ;And also… CREATE INDEX mytable_ndx1 ON mytable

(area(radius_col) );

Benefit: Put your business logic in the server!Benefit: Put your business logic in the server!

A More Complex ExampleA More Complex Example-- Object-Relational System--CREATE TABLE e_Yellow_Pages ( Name VARCHAR(128) NOT NULL, Business Business_Type NOT NULL, Description Document NOT NULL, Location GeoPoint NOT NULL, Occupied SET( Period NOT NULL )); -- “Show me available service stations specializing-- in Porsche brakes within 30 Km of where I

am?”-- SELECT Y.Name FROM e_Yellow_Pages Y WHERE Contains ( Y.Location,

Circle( :GPS_Loc, ‘30 Miles’ ) ) AND Y.Business MATCH “Automotive Service” AND DocContains( Y.Description, “Porsche AND brakes” ) AND NOT Booked ( Y.Occupied,

Period (TODAY,TODAY+5)); --

•Raise the level of abstraction at the database level.

•Buy components to solve common problems, and build components to achieve a competitive edge

Virtual Table InterfaceVirtual Table Interface (VTI) (VTI)• Integration of external data• A single interface that uses a single access

mechanism for ALL data • Transparent to users
