Overview
After configuring the Datastores tab in a workspace with the required target datastores, source datastores, and replications, access the Groups tab to create groups and organize related replications as needed. Replications of a Group can be executed in Parallel or Series Mode. Parallel Mode executes all replications simultaneously, while Series Mode will run them one after the other based on the assigned priorities and their replication dependencies.
When constraints (dependencies) exist on tables, all tables with constraints should be placed in a separate group to ensure that transactions occur in the same order as they were functioned in the source system. If you are setting up a group of refresh replications where tables contain foreign key relations, you need to validate the priority (or order) and replication dependencies of replications to maintain integrity across tables.
Groups configuration involves performing the following two processes:
Creating Groups
- In the Groups panel, click the Add Group button. The Create Group dialog box is displayed.
- In the Name field, enter a unique name for your group.
- In the Description field, enter a brief description that states the purpose of this group.
- From the Execution Mode list, select the preferred execution mode of the replications for this group.NoteParallel mode executes all replications in a group simultaneously, while Series mode will run them one after the other based on the assigned priorities and their replication dependencies.
- Click Save.
A group is created successfully. You can now begin adding the required replications to this group. If you need to create more groups, click Add Group in the Groups panel and repeat Steps 2 through 5.
Note
Refer to Working with the Groups Tab to learn more about the Groups tab and its usage.
Adding Replications to Groups
You can add replications to a Group either from the Datastores or Groups tabs. Note that you can add replications from different target and source datastores combination to a single group; however, replication dependencies are honored only when related replications are executed at the specific target, source, or group combinations. It is recommended to create a separate group for replications that are related to each other or fulfil dependency constraints.
Using the Groups Tab
- In the Groups tab, click Add Replication in the Replications panel. The Add to Group dialog box is displayed.
- From the Target list, select a required target datastore.
- From the Source list, select the source datastores associated with the target datastore. Replications available with the selected datastores are displayed in a table.
- Select checkboxes of the required replications and click Add.
The selected replication replications are created as group members.
Using the Datastores Tab
- Access the Replications panel, and select the checkbox of a required replication to enable the Multi-Select Replications feature.
- Select the checkboxes for the other required replications. The Selected label above the Replications panel displays the total number of selected replications.
- Click Add to Group. The Select Group dialog box is displayed with the list of available groups.
- If you want to create a new group, click New Group and complete the following steps:
- In the Name field, enter a unique name for your group.
- In the Description field, enter a brief description that states the purpose of this group.
- From the Execution Mode list, select the preferred execution mode of the replications for this group.
- Click Save.
- Select the checkbox of the required or newly created group.NoteYou can add replications to multiple groups based on your use case. To do so, select the groups that apply.
- Click Add.
The selected replication replications are created as group members to the newly created group in the Groups tab. Access the Groups tab to verify.
Removing a Replication from a Group
If you have added a replication to a group by mistake or want to remove a replication from a group, complete the following steps:
- Select the group from the Groups panel.
- In the Replications panel, identify the irrelevant replication and click the Delete icon in the Actions column. The Delete Group Member dialog box is displayed.
- Click Confirm to remove the irrelevant replication.
The replication is successfully removed from the group.
Next Steps
After creating required groups to group related replications as per your use case, you can execute and schedule a replication job for those replications in the group. Refer to Execute Replication Jobs and Schedule Replication Jobs for more information.
