For information about custom schema files, see Extending Schema With a Custom Schema File. The following procedure explains how to use the replication mechanism to propagate schema extensions to all the servers in a topology.
For parts of this procedure, you can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help. Other parts of the procedure can only be done using the command line.
Prepare your schema extensions in one of the following ways:
Create your own schema definition file, such as 98mySchema.ldif .
Add your schema extensions to 99user.ldif.
The syntax of definitions in the schema files is described in RFC 4517.
Run the dsadm start or dsadm restart command with --schema-push on the master server where you put the schema definition file.
This script does not actually push the schema to replicas. Instead the script writes a special attribute into the schema files so that the schema files are replicated as soon as they are loaded. For more information, see the dsadm(1M) man page.
Restart the master server where you put the schema definition file.
The replication mechanism cannot detect any changes that you make directly to the LDIF files that contain the schema. When you restart the server, the server loads all schema files and then the replication mechanism replicates the new schema to consumers.
