Class DbRepPreUpgrade_4_1

public class DbRepPreUpgrade_4_1
extends Object

In JE 4.2 the internal format changed for databases with duplicates configured. Duplicates are configured if DatabaseConfig.setSortedDuplicates(true) is called in the base API, or a MANY_TO_ONE or MANY_TO_MANY relationship is used in the DPL API. Before upgrading environments which have duplicates databases to JE 4.2, this utility must first be run using JE 4.1.

This utility is used for replicated environments. For standalone environments, please use DbPreUpgrade_4_1 instead.

The command line for this utility:

 java com.sleepycat.je.rep.util.DbRepPreUpgrade_4_1
   -h <dir>                  # environment home directory
   -groupName <group name>   # replication group name
   -nodeName <node name>     # replicated node name
   -nodeHostPort <host:port> # host name or IP address and port
                                     number to user for this node 
   -helperHosts <host:port>  # identifier for one or more members
                                     of the replication group which can
                                     be contacted for group information,
                                     in this format:
                                     hostname[:port][,hostname[:port]]
 

See main(java.lang.String[]) for a full description of the command line arguments.
