Table 16.3: Data Dictionary Views Associated with Conflict Resolution View Name Description DBA_REPCOLUMN_GROUP Contains information about column groups. DBA_REPCONFLICT Contains information about all conflict resolution methods that have been defined. DBA_REPGROUPED_ COLUMN Contains information about all columns that are members of column groups. DBA_REPPARAMETER_COLUMN Contains information about columns that are designated to resolve conflicts. These columns have been passed in the list_of_column_names parameter of DBMS_REPCAT.ADD_<conflicttype>_RESOLUTION. DBA_REPPRIORITY Contains information about every value and priority that has been defined for all priority groups and site priority groups. DBA_REPPRIORITY_GROUP Contains information about all priority groups and site priority groups. DBA_REPRESOLUTION Contains information about the conflict resolution technique that has been defined for all conflict types. DBA_REPRESOL_STATS_CONTROL Contains information about statistics that have been gathered for conflict resolution. DBA_REPRESOLUTION_METHOD [Appendix A] What's on the Companion Disk? 16.1.3 DBMS−REPCAT Nonprogram Elements 711 Contains information about all available conflict resolution methods. DBA_REPRESOLUTION_STATISTICS If resolution statistics are being collected, contains information about the execution of conflict resolution handlers. Tables 16−4 through 16−14 describe the contents of these views.
