# Restart synchronization at a specific change log event

## About this task

Perform the following steps to restart synchronization at a specific event:

## Steps

1. Search for a specific change log event from which to restart the synchronization state. On one of the endpoint servers, run the `ldapsearch` command to search the change log.

   ```shell
   $ bin/ldapsearch -p 1389
   --bindDN "uid=admin,dc=example,dc=com" \
   --bindPassword secret \
   --baseDN cn=changelog \
   --dontWrap
   ```

   ```
   "(objectclass=*)"
   dn: cn=changelog
   objectClass: top
   objectClass: untypedObject
   cn: changelog
   dn: changeNumber=1,cn=changelog
   objectClass: changeLogEntry
   objectClass: top
   targetDN: uid=user.13,ou=People,dc=example,dc=com
   changeType: modify
   changes::
   cmVwbGFjZTogcm9vbU51bWJlcgpyb29tTnVtYmVyOiAwMTM4Ci0KcmVwbGFjZTogbW9kaW
   ZpZXJzTmFtZQptb2RpZmllcnNOYW1lOiBjbj1EaXJlY3RvcnkgTWFuYWdlcixjbj1Sb290
   IEROcyxjbj1jb25maWcKLQpyZXBsYWNlOiBkcy11cGRhdGUtdGltZQpkcy11cGRhdGUtdG
   ltZTo6IEFBQUJKZ25OWlUwPQotCgA=
   changenumber: 1
             ... (more output)
   dn: changeNumber=2329,cn=changelog
   objectClass: changeLogEntry
   objectClass: top
   targetDN: uid=user.49,ou=People,dc=example,dc=com
   changeType: modify
   changes::
   cmVwbGFjZTogcm9vbU51bWJlcgpyb29tTnVtYmVyOiAwNDMzCi0KcmVwbGFjZTogbW9kaW
   ZpZXJzTmFtZQptb2RpZmllcnNOYW1lOiBjbj1EaXJlY3RvcnkgTWFuYWdlcixjbj1Sb290
   IEROcyxjbj1jb25maWcKLQpyZXBsYWNlOiBkcy11cGRhdGUtdGltZQpkcy11cGRhdGUtdG
   ltZTo6IEFBQUJKZ25OMC84PQotCgA=
   changenumber: 2329
   ```

2. Restart synchronization from change number 2329 using the `realtime-sync` command. Any event before this change number will not be synchronized to the target endpoint.

   ```shell
   $ bin/realtime-sync set-startpoint \
     --change-number 2329 \
     --pipe-name "Sync Pipe 1" \
     --bindPassword secret \
     --no-prompt
   ```
