This section describes the configuration steps required for replication from the primary database. It includes:
Creating a Replication Server connection to the primary database
Creating a database replication definition
Creating the database replication subscription
To create a Replication
Server connection to the primary database
Go to the Mirror Replication Agent scripts, $SYBASE/MA-15_1/scripts/oracle directory:
Make a copy of the oracle_create_rs_primary_connection.sql script:
cp oracle_create_rs_primary_connection.sql my_oracle_create_rs_primary_connection.sql
Before executing the my_oracle_create_rs_primary_connection.sql script against your Replication Server, change all occurrences of value {pds}.{pdb} to the name of the Replication Server connection used for the connection from Mirror Replication Agent for Oracle, where:
pds is rs_source_ds (located in $SYBASE/MA-15_1/init/oracle.rs).
pdb is rs_source_db (located in $SYBASE/MA-15_1/init/oracle.rs).
You must save the defined values to be used for the Mirror Replication
Agent oracle.rs file later in the process.
For example, NY.NYora92.
Change sys and sys_pwd to the user ID and password of the Oracle user who must have permission to apply DML operations against all user tables to be replicated, where:
sys is the user ID of the Oracle user (sys).
sys_pwd is the password of the Oracle user (change_on_install).
This user must be a valid user in the Oracle database.
The following command creates a Replication Server connection to the primary database example:
create connection to NY.NYora92 set error class rs_sqlserver_error_class set function string class rs_oracle_function_class set username sys set password change_on_install with log transfer on, dsi_suspended go
Execute the script in Replication Server:
isql –Usa –P –SSAMPLE_RS -i my_oracle_create_rs_primary_connection.sql
A message is displayed that indicates the Replication Server connection to the primary database is created.
To create the database replication definition
Navigate to the $SYBASE/MA-15_1/scripts/sybase directory:
Make a copy of the rs_create_test_db_repdef.sql script:
cp rs_create_test_db_repdef.sql my_rs_create_test_db_repdef.sql
Before executing the my_rs_create_test_db_repdef.sql script, change the value of “{pds}.{pdb}” to the name of the connection string you defined for the primary database, where:
pds is rs_source_ds (located in $SYBASE/RAX_15_1/init/oracle.rs).
pdb is rs_source_db (located in $SYBASE/RAX_15_1/init/oracle.rs).
For example, NY.NYora92
This is a database replication definition example:
create database replication definition NY_repdef1 with primary at NY.NYora92 replicate DDL go
Execute the script in Replication Server:
isql -Usa -P –SSAMPLE_RS -imy_rs_create_test_db_repdef.sql
A message is displayed that indicates the database replication definition is created.
To create the database replication subscription
Make a copy of the rs_create_test_db_sub.sql script:
cp rs_create_test_db_sub.sql my_rs_create_test_db_sub.sql
Before executing the my_rs_create_test_db_sub.sql script, change the “{pds}.{pdb}” and “{rds}.{rdb}” to the appropriate connection name, where:
pds is rs_source_ds (located in $SYBASE/RAX_15_1/init/oracle.rs).
pdb is rs_source_db (located in $SYBASE/RAX_15_1/init/oracle.rs).
rds is the DirectConnect server name
rdb is any valid identifier. (Sybase recommends that you use the Oracle SID name.)
Here is an example of create database replication subscription:
create subscription NY_sub1 for database replication definition NY_repdef1 with primary at NY.NYora92 with replicate at DCOServer.oratest2 without materialization go
Execute the script in Replication Server:
isql -Usa -P –SSAMPLE_RS -imy_rs_create_test_db_sub.sql
A message is displayed that indicates the subscription is in the process of being created.
Use isql to log in to the Replication Server:
isql -Usa -P -SSAMPLE_RS
Replication Server comes with users who have the permissions necessary for Mirror Replication Agents. However, because Mirror Activator has the capability to create replication definitions, you must grant CREATE OBJECT permission to the Mirror Replication Agent user:
grant create object to SAMPLE_RS_ra go
Permission is granted to user SAMPLE_RS_ra.
This user will be entered in the rs_username parameter
when building the Mirror Replication Agent for Oracle instance.
If you want a user other than the default replication agent user,
make sure that the user is granted CONNECT SOURCE and CREATE
OBJECT permission.
