1 00:00:06,430 --> 00:00:14,410 I'd like to highlight that most organizations that have managed a tedious change controlled process 2 00:00:14,710 --> 00:00:19,630 do not experience the application conflicts in most organizations. 3 00:00:19,630 --> 00:00:27,850 Only one group is likely to make changes to the same objects in a tedious and that group should have 4 00:00:27,850 --> 00:00:33,360 a communication process that ensures that conflicts do not happen. 5 00:00:33,370 --> 00:00:39,530 Now let's review the information about how aid ideas resolves replication conflicts. 6 00:00:39,670 --> 00:00:48,610 When it comes about attribute numbers timestamps and several global unique identifiers these situations 7 00:00:48,910 --> 00:00:52,210 can all this result in conflict resolution. 8 00:00:52,210 --> 00:00:59,990 Now because ADF supports a multiple master replication modal replication conflicts might a cure. 9 00:01:00,070 --> 00:01:08,830 Typically three types of replication conflicts might a cure in aid it is the first one is when simultaneously 10 00:01:08,870 --> 00:01:15,580 modifying the same attribute value of the same object on two domain controllers. 11 00:01:15,580 --> 00:01:22,600 The second situation is when adding or modifying the same object on one domain controller at the same 12 00:01:22,600 --> 00:01:31,120 time let the container object for the object is deleted on another domain controller and the third situation 13 00:01:31,120 --> 00:01:38,800 is when adding objects with the same relative distinguish name into the same container on different 14 00:01:38,800 --> 00:01:43,950 domain controllers simultaneously to help minimize conflicts. 15 00:01:44,020 --> 00:01:52,630 All domain controllers in the forest record and replicate object changes and the attribute or well your 16 00:01:52,630 --> 00:01:55,960 level rather than at the object level. 17 00:01:55,960 --> 00:02:05,200 Therefore changes to two different object attributes such as user is password and postal code do not 18 00:02:05,200 --> 00:02:07,150 cause a conflict. 19 00:02:07,150 --> 00:02:11,250 Even if you change them at the same time from different locations. 20 00:02:11,320 --> 00:02:20,890 When an organization update is applied to a domain controller a stamp is created that travels with the 21 00:02:20,890 --> 00:02:25,150 update as it replicates to other domain controllers. 22 00:02:25,150 --> 00:02:28,790 This term contains the following component. 23 00:02:28,840 --> 00:02:38,230 It contains version number timestamp and server globally unique identifier the version number of starts 24 00:02:38,230 --> 00:02:47,140 at 1 for each object attribute and increases by one for each update when performing an originate and 25 00:02:47,140 --> 00:02:55,360 update their version of the updated attribute is one number higher than the version of the attribute 26 00:02:55,450 --> 00:02:57,700 that is being overwritten. 27 00:02:57,730 --> 00:03:06,100 As for timestamp the timestamp is the updates originating time and date in the year of Universal Time 28 00:03:06,100 --> 00:03:11,950 zone according to the system clock of the Domain Controller where the change a cure. 29 00:03:12,160 --> 00:03:20,590 And lastly server global a unique identifier or greed the server or grid identifies the domain controller 30 00:03:20,620 --> 00:03:24,350 that performed the originate originating update. 31 00:03:24,350 --> 00:03:32,860 Now let's review common replication conflicts and how it is resolved these issues the conflict could 32 00:03:32,860 --> 00:03:35,140 a cure with attribute value. 33 00:03:35,230 --> 00:03:43,570 Even the version number Well it is the same but they attribute well you defers it is evaluate the timestamp 34 00:03:43,900 --> 00:03:51,820 the update operation that has the higher or stamp well you replaces the attribute value of the Update 35 00:03:51,910 --> 00:03:54,930 operation with a lower stamp. 36 00:03:54,940 --> 00:04:02,980 Well you edit is update certain mall to well you attribute such as a well you in a groups member of 37 00:04:03,100 --> 00:04:10,930 attribute and process has them as separate replicable events and other type of conflict that could a 38 00:04:11,100 --> 00:04:20,030 curious add in or move in under a deleted container object or the deletion of a container object it 39 00:04:20,080 --> 00:04:29,710 is resolved sees such issue as follows After resolution a cure set all the replicas aided it is deletes 40 00:04:29,800 --> 00:04:37,680 the container object and the Leaf object is made a child of the Lost and Found container. 41 00:04:37,690 --> 00:04:41,160 This resolution does not involve stamps. 42 00:04:41,210 --> 00:04:48,670 Another issue could a cure with add an object with the same relative distinguished name the object with 43 00:04:48,670 --> 00:04:56,320 the later stamp keeps the relative distinguished name 80 days assigns the symbol an object a unique 44 00:04:56,320 --> 00:05:05,420 name the name assignment is the relative distinguished name plus CnF plus a reserved character which 45 00:05:05,420 --> 00:05:14,490 is an asterisk plus the objects grid this name assignment ensures that the generated name does not conflict 46 00:05:14,790 --> 00:05:16,590 with any other objects. 47 00:05:16,590 --> 00:05:17,010 Name.
