The sponsor node for each Oracle Database Advanced Replication-based replica

C-12 Oracle Fusion Middleware Administrators Guide for Oracle Internet Directory Task 1: Stop the Directory Replication Server on All Nodes To stop the directory replication server, run the following command on each node in the LDAP replication group: oidctl connect=connStr server=oidrepld instance=1 componentname=oidComponentName\ flags=-h LdapHost -p LdapPort stop Task 2: Identify a Sponsor Node and Install Oracle Internet Directory You must identify a sponsor node for this Task. It is the node that supplies the data to the new node. For the RMS, Oracle recommends that you install the new instance of Oracle Internet Directory as an Advanced Replication replica. You could use an existing master node as the RMS, but extra manual steps are required. Install a new Oracle Internet Directory on the remote site. If an existing master is used as RMS, you must follow the instructions in If an Existing Master is Used as a Remote Master Site on page C-5to migrate the masters metadata to the sponsor node. After successfully migrating the masters metadata to the MDS, you can now safely continue with Task 3: Switch the Sponsor Node to Read-Only Mode . Task 3: Switch the Sponsor Node to Read-Only Mode A sponsor node is the node that supplies the data to the new node. To switch the sponsor node from readwrite to read-only mode, use one of the procedures in Changing Server Mode on page 15-2 Task 4: Back up the Sponsor Node by Using ldifwrite Because this may take a long time, you may start Task 5: Perform Advanced Replication Add Node Setup while backup is in process. On the sponsor node, verify that ORACLE_INSTANCE is set, then enter the following command: ldifwrite connect=connect_string \ baseDN=orclAgreementID=000001,cn=replication configuration \ file=output_ldif_file This backs up the directory of the sponsor node. Task 5: Perform Advanced Replication Add Node Setup Note: While the sponsor node is in read-only mode, you may not make any updates to it. You may, however, update any of the other nodes, but those updates are not replicated immediately. Also, the sponsor node and the MDS may be the same node. Note: Oracle Net Service must be configured properly on all nodes for replication. See: On All Nodes, Prepare the Oracle Net Services Environment for Replication on page C-6.
