While entries exist in the t_log table, they cannot be viewed in the User Interface - an error is returned that a number is too large.
This is caused when the sequence number in the t_log table goes over the 32-bit signed integer limit, and requires the values to be reset.
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 USAGE ON SEQUENCE oblicore.SEQ_SLA_LOG to oblidbadmin, oblicore;
Finally, it is possible to restart the "Oblicore - LogServer" service to collect log entries for inserting into the database again.
