Hello guys,
I'm configuring my dataStore 10.5.1 with the ArcGIS Server on Windows Server 2008 R2,
when I clicked on finish I got the error above!
I read all the documentation about the configuration, the only thing that I didn't get is the highlighted sentence:

because during the configuration, I used my "siteadmin" user which is the admin of my arcgis server site, what is a BUILT-IN user ??
EDIT:
progress: the built-in user used in siteadmin ( and it's not the source of error)
I have found the log file of datastore and it's saying that it can't find POSTGRES !!!
( the logfile is in french)
pg_restore: [programme d'archivage (db)] Erreur pendant le traitement de la TOC (« PROCESSING TOC ») :
pg_restore: [programme d'archivage (db)] Erreur à partir de l'entrée TOC 2863 ; 0 0 ACL public postgres
pg_restore: [programme d'archivage (db)] could not execute query: ERREUR: le rôle « postgres » n'existe pas
La commande était : REVOKE ALL ON SCHEMA public FROM PUBLIC;
REVOKE ALL ON SCHEMA public FROM postgres;
GRANT ALL ON SCHEMA public TO postgres;
...
ATTENTION : erreurs ignorées lors de la restauration : 1
but why it is searching for postgres ?? because I wanna work with Oracle as relational database !
