Restoring Read-only Backups for a Coordinator

Restore a coordinator without renaming the utility database to use the coordinator's name. This is the only supported read-only selective restore method for a multiplex coordinator.

Use this procedure to correct problems resulting from inadvertently restoring read-only dbspaces from a read-write archive, or vice versa.

  1. Start the utility server with any server name except that of a secondary node.
  2. Connect to the utility_db and run the RESTORE statement for the read-write database. Use RENAME clauses to move dbfiles to the corresponding locations.
  3. Disconnect and stop the utility server.
  4. Start the restored database. If the database has been moved to a different location, start the server with -iqmpx_sn 1and -iqmpx_ov 1 flags.
  5. Run ALTER DBSPACE <dbspace name> offline for the read-only dbspaces that have been backed up on the separate read-only backup only.
  6. Disconnect and stop the server.
  7. Start the utility database with any server name except that of a secondary node.
  8. Connect to the utility server and run the restore command for the read-only dbspace.
Next
You may restore databases either completely or selectively (by restoring only read-write dbspaces, or a set of read-only dbspaces or read-only files).
