What is conflict resolution in DBMS?
Monitoring Conflict Resolution with DBMS_REPCAT. Conflict resolution is perhaps the most difficult challenge for the administrator of a replicated environment that uses asynchronous replication. A conflict can arise when an insert, update, or delete to a replicated table occurs at two or more master sites.
Which replication style achieves conflict prevention in database replication?
Primary ownership prevents all replication conflicts, because only a single server permits update access to a set of replicated data.
What is DHCP conflict detection?
DHCP conflict detection attempts determine whether the DHCP server sends a test ping for an available IP address prior to handing out the address to a DHCP client. A successful ping means that the IP address currently exists on the network; therefore, the DHCP server does not hand out that address.
How do I resolve conflicts in service now?

- Instance-specific deployment user roles.
- Assign source control permissions.
- Give non-admins permission to use source control features.

Can I delete tombstone files?
Tombstones are dump files from crashed processes. If you are not debugging and don’t need them for troubleshooting (IE you are not in contact with the developer of the crashed app) you can delete them if you have root access.
What are tombstone cells?

What is Oracle GoldenGate conflict detection and resolution?
The automatic conflict detection and resolution feature that is specific to Oracle Database 12 c Release 2 (12.2) You can configure automatic conflict detection and resolution in an Oracle GoldenGate configuration that replicates tables between Oracle databases.
How do I remove conflict detection and resolution from a table?
The REMOVE_AUTO_CDR procedure in the DBMS_GOLDENGATE_ADM package removes automatic conflict detection and resolution from a table. This procedure also removes any column groups and delta conflict detection and resolution configured for the table. Connect to each database as the Oracle GoldenGate administrator.
What is Delta Conflict Detection in SQL?
With delta conflict detection, a conflict occurs when a value in the old column list of the row logical change record (row LCR) differs from the value for the corresponding row in the table. A column group is a logical grouping of one or more columns in a replicated table.
