Re: [keycloak-user] Unable to acquire JDBC Connection
DId you increase the number of connections to the DB? If I don't remember
wrongly it's only max 10 connections or something by default, which isn't
going to cope with a lot of load.

Hi guys,
I get this error:
[0m [31m10:36:26,890 ERROR
[org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (default task-5447)
javax.resource.ResourceException: IJ000453: Unable to get managed

Caused by: org.hibernate.exception.GenericJDBCException: Unable to acquire
JDBC Connection
Caused by: javax.resource.ResourceException: IJ000655: No managed
connections available within configured blocking timeout (30000 [ms])
I use Keycloak 4.4.0-Final and MySQL.
I saw this: https://issues.jboss.org/browse/KEYCLOAK-3539
But it seems to be closed already.
My application is very permission-intensive: on each API request (100 per
second), I request Keycloak permission. That might be wrong design, maybe I
should cache the permissions locally?
Best,
Corentin
