AdministeringIn addition to administering the database server, you can tune performance, replicate data, and archive data.
Enterprise ReplicationThe HCL OneDB™ Enterprise Replication Guide describes the concepts of data replication using HCL® OneDB® Enterprise Replication, including how to design your replication system, as well as administer and manage data replication throughout your enterprise.
Setting up and managing Enterprise ReplicationAfter you design your replication system, you define it and start replication.
Grid setup and managementA grid is a set of replication servers that are configured to simplify administration. When you run SQL data definition statements from within a grid context on a grid server, the statements propagate to all servers in the grid. You can run SQL data manipulation statements and routines through grid routines. You can choose to set up replication automatically when you create a table through a grid. You can propagate external files to other servers in the grid.
Adding an externally created replicate into a grid replicate setIf a replicate is created external to a grid, it can still be added to a grid replicate set.
Adding an existing replicate to a grid replicate set by using cdr change replicatesetYou can use the cdr change replicateset command to add replicates created outside of a grid environment to a grid replicate set.

Adding an existing replicate to a grid replicate set by using cdr change replicateset

You can use the cdr change replicateset command to add replicates created outside of a grid environment to a grid replicate set.

Before you begin

Before you begin, you must verify the following items:

All the replicate participants are members of the grid. Replicate participants must include every member node of the grid, and no additional participants.
Each replicate participant's information refers to the same database, owner, table name and SELECT statement.
The replicated table schema is the same among all participants.
The replicate does not belong to an exclusive replicate set.

Procedure

To add a replicate to a grid replicate set by using the cdr remaster command:

Use the cdr remaster command to convert the replicate to a mastered replicate.
Run the cdr change replicateset command with the --add option and specifying the grid replicate set.
For example, the following command adds a replicate named vendors to the grid1 grid replicate set:
```
cdr change replicateset --add grid1 vendors
```

Results

When you run the cdr list replicate command, the REPLTYPE field shows Grid.
