What’s new in Postgres Plus Advanced Server 9.2?"


Version 9.2 Enhancements..."

u  help organizations reduce IT costs:

•  using existing Oracle skills and features
•  with faster results without expensive hardware
•  better scaling to serve more users
•  keeping data secure
•  increasing application developer’s productivity
•  allows DBAs to manage more databases easily


Oracle: Object types enhancements
Reduced costs using existing Oracle skills and features

u  User defined data types with Attributes and functions for
manipulating data
u  Allows for smaller and more modular data types and
operations that map cleanly to object oriented client
applications making developer’s work faster and easier
u  New:
•  member functions and procedures"
•  syntax compatibility for FINAL, NOT INSTANTIABLE, and OVERRIDING"
u  Also complete syntax support for objects in dump and
restore operations
u  Helps makes migration of Oracle apps easier


Oracle: Object types enhancements

CREATE TYPE CustomType AS OBJECT
(
Object Type Spec
attribute1 INT,
attribute2 REAL,
MEMBER FUNCTION funcplus( arg1 INT) RETURNS INT,
MEMBER FUNCTION funcminus( arg1 INT) RETURNS INT
)

CREATE TYPE BODY CustomType AS Object Type Body
MEMBER FUNCTION funcplus( arg1 INT) RETURNS INT IS
BEGIN
RETURN attribute1 + attribute2;
END funcplus;

MEMBER FUNCTION funcminus( arg1 INT) RETURNS INT IS
BEGIN
RETURN attribute1 - attribute2;
END funcminus;
END;
/


Oracle: PL/SQL like Sub-Types

u  Sub-type derived from an existing base type
u  Adds additional constraints
u  Defined in SPL (procedures/functions/triggers/packages)

DECLARE
SUBTYPE INTEGER IS NUMBER (38,0);
SUBTYPE NAME IS VARCHAR (20) NOT NULL;

var1 INTEGER;
var3 NAME := 'hello'; -- NOT NULL constraint, must initialize

BEGIN
var1 := 38.38; -- can't have fractional part, it will be lost because of constraint
DBMS_OUTPUT.PUT_LINE ('Var1 = '|| var1);
END;


Oracle: new Functions, Syntax, Variable support

u  DROP TABLE mytable CASCADE CONSTRAINTS;
u  "current_date" can now be a variable name
u  "Log" can now be a function name
u  "STRING" is now a data type (maps to VARCHAR2)
u  "NVARCHAR2" is now a data type (maps to VARCHAR)
u  Table() Expressions for Nested Tables:
CREATE OR REPLACE TYPE string_a IS TABLE OF VARCHAR2(765);

select * from table(string_a('abc','xyz')) ;
column_value
--------------
abc
xyz
(2 rows)


Performance: Read Scaling up to 64 cores
Reduced costs with faster results without expensive hardware


Performance: Index Only Scans

u  a.k.a. Covering Indexes
u  All the columns the query needs must be available in the
index, and every row is visible to running transactions
u  Then fetching table data is skipped
•  no disk read"

u  Up to 5x faster in some cases


Performance: Append Hint for INSERTS

u  Adds new rows to the end of the relation
•  Skips the Free Space Map"

u  Improves INSERT performance for tables with frequent
record deletions
INSERT /*+APPEND*/ INTO sales VALUES
(10, 10, '01-Mar-2011', 10, 'OR');

u  Also useful when Bulk Loading data
INSERT INTO sales_history SELECT /*+APPEND*/ FROM sales;


Scalability/HA: xDB Multi-Master Replication
Reduced costs by scaling to serve more users

u  True multi-master replication – edit any data from any
master
u  more details in a moment...


Privileges on Data Types
Reduced costs keeping data secure

u  Restricts which users can create dependencies on types

u  Ensures the object owner can alter a type

u  Supports the SQL-conforming USAGE privilege on types
and domains


VIEW Security Barriers
Reduced costs keeping data secure

u  Prevents data leakage in certain VIEW use cases

u  Use when a VIEW provides row-level security

u  Prevents using functions and
operators on non-View rows
until after the VIEW has done
its work


JSON Data Type
Reduced costs by increasing application developer’s productivity

u  Stores JSON (JavaScript Object Notation)

u  Makes for easier web application development

u  Validates data on Insert/Update

u  Supporting functions:
•  array_to_json() Returns the array as JSON"
•  row_to_json() Returns the row as JSON"


RANGE Data Type
Reduced costs by increasing application developer’s productivity

u  Stores a range of data for a given type

u  Supports operators to calculate containment, overlaps,
intersections, emptiness, and upper/lower bounds

u  e.g. prevent overlapping bookings for a room

u  Easier creation of calendaring, scientific, and financial
applications


Management Enhancements
Reducing costs by managing more databases

u  New pg_dump options support faster restores
•  Allows custom ordering of the restore of meta-data and data"
•  table structure and check constraints ﬁrst, "
•  then data, "
•  then indexes, unique constraints, foreign keys"

u  pg_upgrade enhancements
•  in-place upgrades without dump/restore"
•  handles more use cases"
•  improve logging and failure reporting"

u  Postgres Enterprise Manager 3.0
•  more in a few minutes..."


Advanced Server v9.2 - Conclusion"

u  Oracle shops can continue to reap investments in their Oracle
skills and Oracle features used without the high costs of Oracle
licenses

u  Performance and scaling improvements mean less expensive
hardware and serving more users

u  Secure data helps reduce costly mishaps and intrusions

u  Developers are more productive

u  DBAs are more productive easily managing more databases
with less downtime"


What’s new in xDB Replication Server 5.0?"

xDB MMR - Ideal for Geo-dispersed servers"


xDB MMR - Ideal for Geo-dispersed servers"
u  Each geography updates a local master faster than to a single
common master for all geographies

u  Network latency for local writes is reduced compared to remote
access

u  If any master fails, its traffic can be re-routed to another
geography's master until recovery, or

u  Each geography can also have its own Hot-Standby

u  All locations can utilize commodity hardware

u  All masters continuously synchronize eliminating batch updates
from a single master which results in stale data


xDB MMR - Replication Monitoring"

•  Source and Target Master Nodes"
•  Conﬂict Transaction details"
•  Resolution Strategy employed"
•  Resolution Status (Pending, Resolved)"


xDB MMR - Conclusion"

u  Multi-Master Replication Benefits
•  Improves write availability"
•  Improves read scalability"
•  Improves write performance for latency-tolerant applications"

u  Cost Saving Benefits:
•  Lower costs using commodity hardware vs scaling up to expensive
hardware"
•  Serves more users at lower cost"
•  More up to date information is better for the top and bottom line"
