I will try to make my use case clearer:Every time a user logins into my system, so when
keycloak invokes "getUserByUsername()" method or the "isValid()"
method, i do the realm roles synchronization:
i.e.RoleModel keycloakRole;
public UserModel getUserByUsername(RealmModel realm, String username) {
...
for ( MyRole role : MyRoleList) { keycloakRole =
realm.addRole(myNewRole.getName()); keycloakRole.setDescription(myNewRole.getDescription()); }
public boolean isValid(RealmModel realm, UserModel local) {
...
for ( MyRole role : MyRoleList) { keycloakRole =
realm.addRole(myNewRole.getName()); keycloakRole.setDescription(myNewRole.getDescription()); }
This does work well just with a single thread user.When the environment is configured with
20 concurrent threads/users trying to login, i get "deadlock exception". I can
say the one i printed in my first email is a direct consequence of the
deadlock.After:"optministiLock exception"
i get also:09:51:12,677 WARN [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default
task-2) SQL Error: 1, SQLState: 2300009:51:12,679 ERROR

ORA-00001: unique constraint (KEYCLOAK17.UK_J3RWUVD56ONTGSUHOGM184WW2-2) violated
Now my question is:- I never found a point inside the keycloak authentication flow from
which triggering the synchronization operations so i guessed to make this operation inside
the LOGIN phase. Is it right?- doing like this, is the best way or is there a way to hook
the login jpa transaction? the way that all the sync operations are flushed after the
whole login transaction is committed?- Or am i totally wrong and there is a specific
pattern to follow for all the roles and attributes synchronize operations?
thanks

As it times out after 30 seconds to obtain a connection it looks more like
connections/transactions are not being closed. Is your federation provider using the same
datasource? Any chance it's not closing the connections properly?

Hi,i wrote my custom federation provider.All the synchronize operations (roles and
user-roles) are done inside the getUserByUsername and the isValid method.This way every
time a user or a new-user logins into my system, all the roles and role-mapping are kept
up to date.All seems to work well with one user, but now i'm experiencing a lot of
exceptions in a concurrence environment.These are the tests i'm launching:1) 20
concurrent threads, each of which tries to login, to send a REST request (to backend) and
finally to logout. All 20 threads login with the same test username.2) 200 concurrent
threads, doing the same as at the previous point, with 20 differents username.
Everytime each federation provider instance tries to synchronize all realm roles...adding
or removing roles in concurrence, i catch this error:

What's the solution to correctly handle a concurrence environment?What am doing wrong?
Is there a way to make synchronized keycloak jpa transactions?Thanks
