Perform these tasks before you start the demonstrations.
On the source, verify that the SP_OCT_REPLICATE_DDL parameter is set to the default of 3. This parameter controls basic DDL replication, including the TRUNCATE command.
sp_ctrl(source)>list param modified capture
The SP_OCT_REPLICATE_DDL parameter should not be listed in the output. If it is, issue the following command:
sp_ctrl(source)>reset param SP_OCT_REPLICATE_DDL
The p2p.sql and od.sql scripts install the demonstration objects that you will use during these demonstrations. These scripts are stored in the util sub-directory of the SharePlex product directory.

The following are instructions for starting SharePlex and the sp_ctrl command-line interface on Unix and Linux. Start SharePlex on the source and target systems.
To start SharePlex on Unix and Linux systems:
From the bin sub-directory of the SharePlex product directory ( productdir in the following syntax), run sp_cop and sp_ctrl.
$cd /productdir/bin
$./sp_cop &
$. /sp_ctrl
Note: Before proceeding, make certain the SharePlex demonstration objects are installed. See Prework for the Demonstrations .
In this demonstration, you will create and activate a replication configuration, load data to the source table, and then confirm that the data was replicated successfully to the target table. You will also repair a table that is out of synchronization.
Note: In this demonstration, the demonstration objects are assumed to be in the schema named demo. Substitute the actual schema, if different.
Perform these steps on the source system:
Run sp_ctrl .
Issue the following command to create a configuration file named od_config that replicates the od_department, od_salary, od_timesheet, and od_employee tables to target tables of the same names on the target system.
sp_ctrl(source)>create config od_config
In the text editor, build your configuration file based on the following template. Allow no spaces between the characters in a component (source specification, target specification, routing map), and place at least one space between each component.
# od_config configuration file | ||
datasource:o.source_SID | ||
demo.od_department |
demo.od_department |
target_system@o.target_SID |
demo.od_salary | demo.od_salary |
target_system@o.target_SID |
demo.od_timesheet | demo.od_timesheet | target_system@o.target_SID |
demo.od_employee | demo.od_employee | target_system@o.target_SID |
where:
In sp_ctrl, verify that the configuration file will activate successfully.
sp_ctrl(source)>verify config sample_config
Perform these steps on the source system. When you activate a configuration, SharePlex is ready to capture transactional changes that are made to the specified source data.
Perform the following steps to activate the configuration:
Activate the configuration.
sp_ctrl(source)>activate config od_config
Note: Configuration names are case-sensitive.
Confirm that the configuration activated successfully. The name config od_config should appear under File Name, and the word Active should appear under State.
sp_ctrl(source)>list config
Note: If you ran the basic SharePlex demonstration using the same datasource , this activation deactivates the configuration file that you used for that demonstration.
On the source, log in as the demo schema owner and execute the od_add_emps procedure to populate the od_employee and od_salary tables.
This procedure has one IN parameter that specifies the number of employees to insert per department:
SQL> exec od_add_emps(100);
In this section, you will compare the source and target tables to verify that the data is synchronized.
On the source, run sp_ctrl.
On the source, compare the od_employee and od_salary tables to their targets.
sp_ctrl(source)> compare demo.od_employee
sp_ctrl(source)> compare demo.od_salary
Note: The command determines the correct target table from the configuration file.
On the source, view the results of the comparisons.
sp_ctrl(source)> compare status
Continue issuing this command until both compare processes have completed their work. The command output should show no out-of-sync rows.
In this section, you will repair an out-of-sync condition to restore data synchronization.
Perform the following steps to repair an out-of-sync condition:
On the target, run SQL*Plus and delete some rows from od_employee. This causes that table to go out of synchronization with its source table.
On the source, compare the od_employee tables.
sp_ctrl(source)> compare demo.od_employee
On the source, view the results of the comparisons.
sp_ctrl(source)>compare status
The command output should show out-of-sync rows, the number of which should equal the number of rows you deleted from od_employee on the target.
On the source, repair the od_employee table.
sp_ctrl(source)>repair demo.od_employee
On the source, view the results of the repair.
sp_ctrl(source)>repair status
The command output should show no out-of-sync rows, because the repair command inserted the rows that that you deleted, because they were still present in the source table.
Note: Before proceeding, make certain the SharePlex demonstration objects are installed. See Prework for the Demonstrations .
In this demonstration you will:
Define a partition scheme and one or more row partitions for the partition scheme.
A row partition is a defined subset of the rows in a source table that you want to replicate to the target table.
A partition scheme is a logical container for row partitions.
Note: In this demonstration, the demonstration objects are assumed to be in the schema named demo. Substitute the actual schema, if different.
Perform the following steps to prepare the table:
If you ran previous demonstrations, do the following:
On the source and target, run sp_ctrl and issue the following command to shut down sp_cop.
sp_ctrl (source) shutdown
sp_ctrl (target) shutdown
On the source and target, TRUNCATE the od_employee and od_salary tables.
SQL> truncate table demo.od_employee;
SQL> truncate table demo.od_salary;
Perform the following steps to configure the row partition:
On the source, create a row partition that specifies the rows to replicate from the source od_employee table, in this case only the rows where the employee department is 1.
Note: The partition only specifies rows. The names of the source and target tables are specified in the configuration file.
sp_ctrl> add partition to scheme1 set condition = 'EMP_DEPT_NO=1' and route = target_sys@o.ora_SID
where:
Perform these steps on the source system.
In sp_ctrl, open the od_configconfiguration file for editing.
sp_ctrl(source)>edit config od_config
In the text editor, edit the configuration file to change the entry for the od_employee table so that it uses the partition scheme that you created.
# od_config configuration file | ||
datasource:o.source_SID | ||
demo.od_department |
demo.od_department |
target_system@o.target_SID |
demo.od_salary | demo.od_salary |
target_system@o.target_SID |
demo.od_timesheet | demo.od_timesheet | target_system@o.target_SID |
demo.od_employee | demo.od_employee | !scheme1 |
Where:
Perform the following steps to activate the configuration:
Perform these steps on the source system. When you activate a configuration, SharePlex is ready to capture transactional changes that are made to the specified source data.
Activate the configuration.
sp_ctrl(source)>activate config od_config
Note: Configuration names are case-sensitive.
Confirm that the configuration activated successfully. The name config od_config should appear under File Name, and the word Active should appear under State.
sp_ctrl(source)>list config
Perform the following steps to replicate data:
On the source, log in as the demo schema owner and execute the od_add_emps procedure to populate the od_employee and od_salary tables. This procedure has one IN parameter that specifies the number of employees to insert per department:
SQL>exec od_add_emps(100);
On the source, select all rows from the source od_employee table.
SQL> select * from od_employee;
The value for the EMP_DEPT_NO column should range from '1' to '5' across the rows.
On the target, select all rows from the target od_employee table.
SQL> select * from od_employee;
The value for the EMP_DEPT_NO column should be '1' for all rows. Rows where the value for this column is a value other than “1” were not replicated.
