 Travel service provider needs data integration to improve customer satisfaction
• Legacy implementation was a manual script-driven batch process. Logistics
information updated local agencies weren’t captured and delivered to Central site.
Hence, customers weren’t able to get accurate information on time.
 Sybase Replication Server synchronizes logistics data in heterogeneous environment
• Collects changed data from heterogeneous sources
• Replicate in real-time to other heterogeneous targets
 Achieved real-time data integration
• This solution enables this customer to provide better services and improve customer
satisfaction, which contributed to customer acquisition and retention
One Architecture For Data Movement and
Disaster Recovery
Increased requirement to support multiple databases:
 Mergers, acquisitions, 3rd party applications, legacy
applications
 Need to staff DBA skills for all databases in environment
 Data movement and disaster recovery efforts require a
different set of DBA skills
 If data movement or disaster recovery solutions are the same
across databases then only one set of skills is required
 Numerous sites currently use Replication Server and have
these skills
 Replication Server skills are easily extended to replicating
other databases

RAO 12.6 at a glance
Log Based
• No need for a “virtual” log based on tables
• No need for triggers to populate those tables
All JAVA written, requires JRE 1.4.2
– JRE bundled in RAO
– Requires Oracle JDBC Driver 9.2.0.5 for JDK 1.4
Not shipped with the product !
Embedded ASA, known RASD
Compatible with:
– RS 12.5, RS 12.6 and RS 15.0
Prior RS 12.5 will truncate LOB data-types to 2G and CHAR, VARCHAR2, RAW to 255
characters
Prior RS 12.5 will replicate NCHAR and NVARCHAR as CHAR and VARCHAR (ASCII not
Unicode)
– jConnect/jTDS version 6.0 EBF 12723
– ECDA 12.6.1 (for LOB replication)
RAO 12.6 at a glance, connectivity
RASD
Not Displayed: Each RAO instance has a configuration file
RAO 12.6 at a glance, RASD

RASD = Replication Agent System Database

Started as a personal server ( dbeng8.exe )
•
•
ASA name same has the instance name
Started at instance name port +1

Initially empty until the rep agent is initialized (pdb_xlog init)

Holds the metadata about the primary database
•
•
•
Database schema
Objects marked for Replication (pdb_setrepproc, pdb_setreptable, pdb_setrepcol, pdb_setrepseq)
Contains versions when a DDL command modifies the database schema, to replay transactions that involved objects before the
change made by the DDL command
 Size of the RASD depends on the number of objects marked for replication
 Every instance of the RAO has its own RASD
 Information stored in ASA not relevant outside the Rep Agent
 Internal ASA schema subject to change for BETA / GA / EBF
•
Building a new RAO instance is required, do not reuse the .db/.log files
 Administration command via RAO
•
rasd_backup, rasd_restore, ra_truncatearticles, ra_truncateusers
RAO 12.6 at a glance
 Read directly from Oracle’s redo log files
 Replication Agent must be installed on a machine from which
it can directly access the redo log files (same host or host with
shared access)
• This the only requirement
 RAO will perform the log archiving as data in redo logs is
replicated.
RAO 12.6 at a glance, components and flow
LTI: generates LTL for Replication Server
LTM: manages all the components and interactions
Log Reader: Reads the transaction log in the primary database to retrieve txs
RAO 12.6, Oracle Configuration, part 1
 Oracle configuration needed to work with RAO
 Oracle Archiving log must be on:
• Run: alter database ARCHIVELOG ;
• Verify: select log_mode from v$database;
 Automatic Archiving must be disabled:
• Run: alter system set log_archive_start=false scope=spfile;
• Verify: show parameter log_archive_start;
 Restart the Oracle Server
 RAO truncates the ORACLE log
•
•
•
•
Depends on ra_config truncation_type interval | command
Automatic: ra_config truncation_interval, a_value_in_minutes( 0..720)
Manual: pdb_truncate_xlog
Sends the Oracle command: alter system archive log
RAO 12.6, Oracle Configuration, part 2
 Tell Oracle to log primary keys
• Run: alter database add SUPPLEMENTAL LOG DATA
(PRIMARY KEY, UNIQUE INDEX) COLUMNS;
• Verify: select SUPPLEMENTAL_LOG_DATA_PK from
V$DATABASE;
RAO 12.6, Oracle Configuration, part 3
RAO User
 Add an Oracle user for the RAO to connect to the primary DB:
• create session
• select_catalog_role
• alter system
• alter any procedure, create procedure
• create public synonym, drop public synonym
• create table
• execute on DBMS_FLASHBACK
• select on SYS.OBJ$
• select on SYS.LOB$
• select on SYS.COLLECTION$
• select on SYS.COL$
RAO 12.6, Creating a RAO instance
 A RAO server is called an instance
 N instances can be created in a machine:
• Instance name must be different
• Instance port must be different
 One instance has one type (here Oracle, could be also UDB,
MSSQL, Informix)
 An instance is created via:
• Command line
– Ex: ra_admin –c <instance_name> -p 10000 –t oracle
• GUI
– Run the administrator command in the RAX\bin directory
RAO 12.6 DDL Replication
 Only available for Oracle, the other RepAgents do not replicate DDL
 Must use Oracle as the replicate database, cannot replicate DDL from
ORACLE to NON-ORACLE DB
 Must define a new Oracle user
• Not the maintenance user / Not the Replication Agent user
• Has to be created in the replicated database
• Identified in RAO with ddl_username and ddl_password
– Has to have the following permissions:
ALTER SESSION, RAO sends this commands as the first command for
every DDL transaction
ALTER SESSION SET CURRENT_SCHEMA=user, where user is the
user that generated the DDL command at the primary
Permission on rs_info and rs_lastcommit
Permission to create any DDL commands ( create / drop… )
RAO 12.6 DDL Replication
 To replicate DDL in oracle, use:
 pdb_setrepddl [enable | disable]
 Replication Server must have a database level replication definition with
replicate DDL set in the definition.
 create database replication definition whatever with primary at rao_instance.ora_instance
 replicate DDL replicate tables replicate functions
 create subscription orardb_sub for database replication definition whatever
 with primary at rao_instance.ora_instance with replicate at DCO_ORACLE.orardb without
materialization
RAO 12.6 DDL Replication

Audit / no audit
RAO 12.6 DDL Replication
 Objects not replicated:
• Any Object owned by SYS
• Any objects owned by users defined in the list of non replicated users (
see pdb_ownerfilter )
RAO 12.6 Stored Procedure Replication
 Behaves similarly to the trigger based implementation in RAX 12.5.
 Proc-Active and shadow tables are created on the primary database to support
stored procedure replication ( Oracle does not log stored procedure execution)
 Primary stored procedure is instrumented during marking of the procedure to be
able to update the proc-active/shadow table.
 Use pdb_setrepproc to mark/enable or unmark/disable primary procedure for
replication (caution DDL replication must be disabled before running the command)
 To be able to mark an Oracle procedure or function, it must be a standalone. The
Oracle procedure or function cannot be part of a package.
RAO 12.6 Stored Procedure Replication
 Stored Procedure Example ( this is what you type)




CREATE PROCEDURE ADD_EMPLOYEE ( PEMP_ID NUMBER … ) AS
BEGIN
/* whatever Oracle SQL */
END ;
 In RAO run




pdb_setrepproc ADD_EMPLOYEE, mark
go
pdb_setrepproc ADD_EMPLOYEE
go
 Owner Name

END ;
RAO 12.6 Binary Object Replication
 Oracle LOB datatype support:
• Character:
– LONG: 2G field Max, 1 per table (deprecated in Oracle 9/ for
compatibility), not possible to partition the table (text)
– CLOB: ASCII, max 4G (text)
– NCLOB: UNICODE, max 4G (text)
• Binary
– LONG RAW: 2G field Max, 1 per table (deprecated in Oracle 9 / for
compatibility), not possible to partition the table (image)
– BLOB : Binary, max 4G (image)
– BFILE : a pointer to a file stored outside the db (image)
• Oracle replication cannot replicate LONG / LONG RAW data
RAO 12.6 Binary Object Replication
 Mark the table containing the LOB columns for replication using
pdb_setreptable table
 If pdb_dflt_column_repl is set to true then marking the
table will mark all the columns for replication
 Use pdb_setrepcol to mark LOB columns for replication, if
pdb_dflt_column_repl is set to false ( the default)
 pdb_setrepcol table, column, enable | disable
LOB Replication
 Depending on the size and storage configuration of the
LOB, the data is either logged in-row or off-row via the
Oracle “disable storage in row”
 Data logged in-row is logged in the same log record as all
other non-LOB column data.
 Data logged off-row is logged in a separate log record, and
a pointer is logged in the row with the non-LOB column
data
LOB Replication
 LOB data may be changed without updating other column data
• Updates to off-row LOBs via DBMS LOB package
• No supplemental logging included for LOB updates in Oracle 9.0 (fixed in 9.2)
• Example:
–
–
–
–
Update T set reg_col2 = 2 where reg_col1 = 1
Reg_col1 and reg_col2 are recorded in the redo log
Update T set lob_col = “something” where reg_col1 =1
Only lob_col is recorded in the redo log -> no way to reconstruct the where clause
 In these cases, RAO requires that a LOB update be directly preceded or
followed by a non-LOB update to the same row (insert or update )
• Update T set reg_col2 = 2 where reg_col = 1 <- to execute after the update of
the LOB column
• Commit;
• There is no way for RAO to force compliance
LOB Replication
 CLOB, NCLOB and BLOB data logged off-row is logged
prior to the in-row column data in separate log records
 RepServer requires that the in-row column data be sent
first, so LogReader skips off-row LOB data until it sees the
in-row column data, and then re-reads the off-row LOB
data
LOB Replication
 LONG and LONG RAW LOB types are stored in-row like
non-lob data
 Only one column of type LONG is allowed per table
 Since LONG data is always logged as the last column, no
matter its actual column position, the article definition is
altered to reflect this behavior when it is stored in the
repository
 Otherwise, LONG data is treated like any other in-row LOB
LOB Replication
 BFILE data is stored external to the database and only a
pointer to the file is logged, not the data itself
 Handled in a similar way as trigger-based solution, when a
BFILE column is changed, RAO queries the primary
database for the data
• Selecting the BFILE data separate from other data in the redo
log can provide a temporary out-of-sync condition if the BFILE
contents are changed multiple times.
RAO 12.6 UDD Replication
 User Defined Data types use ORACLE built-in data types and other user
data types
• CREATE TYPE customer_typ_demo AS OBJECT

( customer_id NUMBER(6) , cust_first_name VARCHAR2(20) , cust_last_name
VARCHAR2(20))
 UDD can also have methods associated to it (PL/SQL, C, JAVA) # like a
class
 To replicate UDDs in Oracle:
• A special datatype must be created in RS and that datatype must be used as the
datatype for any UDD column defined in a replication definition
• Choose an un-used datatype in rs_datatype table ( column is dtid )
• In RSSD: Insert into rs_datatype ( …. ‘rs_jc_dt’ …) //this is the name of the datatype
• Create replication definition jc_repdef with with primary at ra_source_db.ra_source_ds
with all tables named ‘ORACLE_TABLE‘ (PKEY int, PNAME rs_jc_dt) …
Sequence Replication
 Replication Server does not directly replicate sequence type.
 To support sequence replication, you must:
• Install the stored procedure rs_update_sequence on the
standby site using the
oracle_create_replicate_sequence_proc.sql script.
• Install the function replication definition
rep_update_sequence for that procedure in Replication
Server using the
oracle_create_rs_sequence_repdef.sql script.
(Scripts reside under Mirror Replication Agent installation’s
scripts directory - %SYBASE%\MRO-12_6\scripts)
 Use pdb_setrepseq command to mark/enable or unmark/disable
a primary sequence for replication.
RAO 12.6
Non supported Oracle data types
 Listed of non supported Oracle data types
• ORACLE REF
– A logical pointer to a row
– The oracle way to reduce foreign keys
– CREATE TYPE person AS OBJECT ( name VARCHAR2(30), manager
REF person );
• ORACLE VARRAY
– A Variable Array

MESSAGING OVERVIEW
Sybase Confidential Proprietary.
Messaging and Queuing
 Messaging - programs communicate by sending data in messages
rather than by calling each other directly.
 Queuing - messages are put on queues in storage, eliminating the need
for programs to be logically connected.
 A messaging and queuing framework is inherently ASYNCHRONOUS!
How Messaging & Queuing Works?
Programs communicate by putting
messages on queues. Here, program
A puts a message on Queue1, which
is read by program B.
Communication can be one-way or
two-way. Here, A sends to B on
Queue1, and B responds to A on
Queue2
Note: A and B need not be on the same machine!
Messaging and Queuing Characteristics
 Three key facts about Messaging and Queuing differentiate it from other
communication styles:
1) Communicating programs can run at different times.
2) There are no constraints on application structure.
3) Programs are insulated from environmental differences.
MESSAGING STANDARD
 Messaging standard (specification) defines the framework and contract
used by the applications
 Messaging standard, just like any, defines core API for use by
applications
 Messaging standard is generally programming language neutral
 Popular messaging standards
• MQI (Messaging and Queuing Interface) – Defined by IBM
• JMS (Java Messaging Service) – Part of Java Standard
– Derives number of concepts from IBM MQ
MESSAGING MODELS
Point To Point



Any given message can only be read by one application
These are known as queues
Multiple receivers are allowed, but only one receiver will get the message
Publish and Subscribe





One to many
In JMS these are known as topics
In IBM MQ these are known as subjects
Publishers posts messages pertaining specific subjects/topics
Consumers establish subscriptions to register interest in messages sent
to a topic
What is JMS?
 Java Message Service
 Standardized messaging API
• Developed by Sun in conjunction with TIBCO and others
• Component of Java 2 Enterprise Edition (J2EE)
• http://java.sun.com/products/jms/index.html
 API only
• An API to which vendors can build implementations
• No specification of wire format, namespace or access
control, etc.
• Message portability for bridge-building
MESSAGE FORMAT - JMS
Three parts to a JMS Message
 Message Header
 Message Body
 Message Properties
Message Header
 Defined by JMS standard, and includes vendor specifics
 Example: Message-ID
Message Body
 Application data (payload)
 JMS defines structured types (Stream, Map), and unstructured (Text, Bytes,
Object)
Message Properties
 User defined
 Typed and can be used by receivers to control which messages they are
interested in
 Example: application_name, application_version

What is MQ Series?
•
MQSeries is a middleware product from IBM that runs on multiple platforms
and enables applications to send messages to other applications
•
Basically, the sending application PUTs a message on a Queue, and the
receiving application GETs the message from the Queue
•
The sending and receiving applications do not have to be on the same
platform, and do not have to be executing at the same time
•
MQSeries takes care of all the storage, logging and communications details
required to guarantee delivery of the message to the destination queue
•
In most cases, it will take care of translating the data when the source and
destination use different character sets (EBCDIC on MVS vs. ASCII on NT or
Unix)
•
All the applications have to do is know the name of the Queue and agree on
the meaning of the message.

ASE MESSAGING NATIVE SUPPORT
Sybase Confidential Proprietary.
ASE Real Time Messaging Service (overview)
Functionality Overview

Brings the Messaging (JMS / MQ ) services into ASE using
 Simple SQL functions in ASE to publish and consume messages to and from a
message bus
 Transform messages into XML format before publishing

Supports Point-To-Point and Publish–Subscribe messaging paradigms

Preserve transactional semantics across the database and message bus (e.g., if a
transaction fails then message won’t be published)

Graphical User interface is provided via Sybase Central/ASE Plug-in


Only for adding/dropping of the message services providers and registration of subscriptions
Workspace 1.5 has support for building the syntax to send and receive messages from both TIBCO
and MQ-SERIES.
ASE Real Time Messaging Service
(Concepts)
ASE_MESSAGING
 License for messaging functions
sp_configure “enable real time messaging”
 Turns on the messaging feature
sp_configure “messaging memory”
 Configures the amount of memory for messaging needs
Messaging_role
 Must be granted to logins that will use the messaging function
sp_msgadmin
 Messaging administration stored procedure
 Each variant has a command and an optional sub-command
 sp_msgadmin help will provide more details
ASE Real Time Messaging Service (TSQL)
Functions related to queues
 msgsend() – send a message to a queue
 msgrecv() – receive a message from a queue
Functions related to topics
 msgpublish() – publish a message to a topic
 msgconsume() – consume a message from a topic
 msgsubscribe() – start a subscription
 msgunsubscribe() – stop a subscription
Functions related to message properties
 msgproplist() – returns the properties and their values
 msgpropname() – returns the name of a property
 msgpropvalue() – returns the value of a property
 msgproptype() – returns the type of a property
 msgpropcount() – returns the number of properties
ASE Real Time Messaging Service (Q
engine)
 sp_configure “max online Q engines” (default = 0)
•
Configures maximum number of ASE engines that can be use for
MQ Messaging
 sp_configure “number of Q engines at startup”
(default = 0)
•
Configures the number of ASE engine that is used for MQ
Messaging
 These are static configuration parameters, the ASE
server must be rebooted after setting them.
Transaction Support
 Transactional Behavior, Three Modes
• Simple
– Messages sent and received are part of the ASE transaction
– Rollback in ASE will undo the work at the bus side
– Errors on the bus do not rollback the ASE transaction
• Full
– Messages sent and received are part of the ASE transaction
– Rollback in ASE will undo the work at the bus side
– Errors on the bus will rollback the ASE transaction
• None
– Messages sent and received are not part of the ASE transaction
– Rollback in ASE will not undo the work at the bus side
– Errors in the bus will not rollback the ASE transaction
 Session Specific
 Control by the set transactional messaging command
• Set transactional messaging full | simple | none

HA for RTDS
RTDS 3.5 Background
• Previously tibco api was coupled tightly with ASE by including the
header files directly within the codeline.
• Reduce the tight coupline/dependency on tibco code:
• Remove any license implications
• Increase opportunities for the product
• Header files were isolated into separate DLL's that get loaded dynamically
on demand.
• DLL's released only to customers that have purchased RTMS/RTDS
licenses.
New Feature Description
• Isolate 3rd party messaging include files from core ASE into
separate DLL's.
• Separate ASE_MESSAGING into ASE_MESSAGING_TIBJMS and
ASE_MESSAGING_IBMMQ
New DLLs for each type of 3rd party messaging
provider




+ The only places in ASE source code that will include 3rd party
headers will be the sources for these DLL's.

+ 3rd party include files are no longer included by ASE core code.



+ ASE will load these DLL's if messaging is configured for that type of
messaging provider. The path to the DLL's is hardcoded to the paths
under $SYBASE.




+ The new DLL's have generated version and copyright strings, and have
functions to return their version numbers. This is for future upward
compatibility in case we need to change the interface between ASE
and the DLL's.
Code changes







+ There are no external functional changes that customers will notice.
+ Code changes are mainly in the following categories
o Functions that load the new DLLs.
o All calls to KRTMS worker functions are now through function
pointers.
o These are the KRTMS functions that make the actual 3rd party
provider API call. The logic of how the 3rd party API calls are
made or of the RTMS or higher KRTMS layers is not changed.
o Build changes (see below)
3 Layers
 The implementation is divided into three layers

a server layer (RTMS),

a kernel layer (KRTMS),

an interface DLL layer

(libsybtibems.so or libsybibmmq.so).
New Work Flow for 3 Layers
RTDS 3.5 New Interface
If you are using:
• Both MQ and JMS, enter:
sp_configure 'enable real time messaging', 1
•Only MQ, enter:
sp_configure 'enable real time messaging', 1, 'ibm_mq'
•Only JMS, enter:
sp_configure 'enable real time messaging', 1, 'tibco_jms'
RTDS 3.5 Licenses
• Separate ASE_MESSAGING into ASE_MESSAGING_TIBJMS
and ASE_MESSAGING_IBMMQ.
• This is a follow up to split out the messaging provider API calls into
separate dll's.
• This gives us more flexibility to package RTDS w/o incurring
licensing liabilities from the 3rd party messaging providers.

SUMMARY
 Messaging architectures enable sharing information
among multiple applications
 But databases today store information until
applications ask for it
 With Sybase Real Time Data Services (RTDS)
database events are pushed to applications the
moment change occurs
 Sybase RTDS enables information flows that are
faster, more relevant, and actionable
