First shutdown the service "Oblicore - LogServer" on the App server.
Then truncate the table t_log in the database.
Then drop the sequence seq_sla_log.
Then execute this script to recreate the sequence:
CREATE SEQUENCE oblicore.SEQ_SLA_LOG
START WITH 1000
GRANT select ON oblicore.SEQ_SLA_LOG to role_usr_reg_privs;
Finally, it is possible to restart the "Oblicore - LogServer" service to collect log entries for inserting into the database again.
