No ManagedConnections available

we have started facing a very strange issue recently on production, this issue occurs only on Monday's between 8:30AM t0 9:30 AM
The inUseConnections count goes to become 20 in no time and application hangs and we have to flush the connections to get it back to working.
the error seen in the logs is:
2016-05-16 09:18:31,156 ERROR [org.hibernate.util.JDBCExceptionReporter] No ManagedConnections available within configured blocking timeout ( 30000 [ms] ); - nested throwable: (javax.resource.ResourceException: No ManagedConnections available within configured blocking timeout ( 30000 [ms] ))

Could you please help me understand what could be the reason behind this and how can this be resolved.
Thanks in advance.
Note: we haven't seen this issue before in our application, it was working fine for many years, all the connections in the application are being closed properly.

Well, its hard to point the exact reason without knowing your business flows.
I think that if you're running out of available connections, obviously someone consumes them.
In general it can be:
Option 1:
The same code, called simultaneously. For example, in the provided stack trace I see:
com.baad.merc.service.proposal.impl.ProposalServiceImpl.retrieveProposalSummary(ProposalServiceImpl.java:1050)
I would check that, by placing some counter/metric. Since you're using AOP, it shouldn't be hard to implement as an aspect or something.
Option 2:
There are just too many users using your application at that period of time, so they run their requests. This also can be tracked like this: when you reach, say, 19 connections (again you can use counter for measuring that) - just create a thread dump programmatically and store it in some place on the filesystem. So you'll be able to track the flow that actually caused this situation.
Similarly it can be even some internal activity, for instance a scheduled job or something.

java.net.ConnectException: Connection refused apache mysql

i try to run my code on the server using tomcat8, spring4 and maven. Locally is everything fine, but no on the server.
jdbc.driverClassName=com.mysql.jdbc.Driver

A part of my pom.xml with the mysql dependency:
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.1.26</version>
</dependency>
Any ideas?
Thank

Make sure you have the necessary user and host combinations visible in select user,host from mysql.user where user='root'
If they are not there for localhost or 127.0.0.1 or IPADDR or hostname then create them with mysql create user command and apply grants.
If the server is DNS blind and you are using a name to connect (DNS blind would not be the case for clients), then figure that angle out. For instance, my client can ping cnn.com, some of my servers cannot.

Look at most embedded exeption: java.net.ConnectException: Connection refused
It means, that there is some problem with network connection, not with the database itself.
Here some hints, which may help you:
make sure, that database is running on the DB server, and that ports are opened (tools like netstat may help);
check, if you can connect to the remote database with other software, for example MySQL Workbench;
check your network connection between peers. It is hard to advise anyhing detailed here, all depends on your network configuration.

I know there is the "libros" table, because I created it myself and consult the MySQL Workbench. Clarified that the MySQL Server is local, as well as the application.
Further, the strangest thing is that if I connect with the same application to an online MySQL, no error is displayed.
I am connecting to the latest MySQL JDBC connector and also tried other previous versions, but the problem is the same.
Of course, I appreciate your attention.
Gustavo Echenique

You are getting " MySQLSyntaxErrorException: Unknown database 'libros' ".
You initially said libros was a database; but in a later statement called it a table - Check that you haven't created a table called libros, and not a database. Which is one potential cause for this type of error.
For further help, provide the create statement used, as well as the sql query.

Ensure that you are connecting to the correct host and that the MySQL host you are connecting to has the 'libros' database.
Also, check if the user you are using in your JDBC configuration have access to the 'libros' database.
Try this command:
SHOW GRANTS FOR 'user'#'localhost';

I am compelled to apologize for the time I lost them.
The database is called "arquitecturajava" and has a table called "libros".
When I tested with MySQL online, I called the database as "libros", so when I tried the local server did not work.
Thank you very much for your help.

I'm having much trouble figuring a MySQL error log

I made a web-app using JSF, MySQL, and NetBeans(web-app template-design).
Here's the error-trace I get: http://adelazzam.com/errorTrace.htm

What is the cause and how can I fix it?

In case of large stacktraces, always head to the lastmost one for the real root cause:
Caused by: java.sql.SQLException: Error in allocating a connection. Cause: null
Thus, a connection cannot be obtained from the datasource. Apparently the datasource itself is null. You need to create a MySQL datasource in Glassfish. There are several ways:
By Glassfish admin console: http://www.albeesonline.com/blog/2008/08/06/creating-and-configuring-a-mysql-datasource-in-glassfish-application-server/
By commandline: http://weblogs.java.net/blog/felipegaucho/archive/2010/03/04/glassfish-v3-resources-administration-cli-tool-asadmin
By XML config file: http://pooriamellati.wordpress.com/2010/05/21/configure-mysql-pool-and-resource-in-glassfish-v3/

Deploy JSF App on Glassfish 3

I have developed a JSF apllication using Netbeans and Glassfish 3.0.1.
Now on another machine (Server) I installed glassfish 3.0.1 and deployed the application with default settings except I created the Pool before deployment.
But when I launch the application it ends up with this error message:
An Error Occurred:
An error occurred performing resource injection on managed bean index

This has nothing to do with JSF. Your datasource is missing. Makes sure you have declared the jdbc/Gates datasource.

Bozho's assertion is correct. You need to register the jdbc resource and the jdbc connection pool on any server instance where you attempt to deploy this war file.
NetBeans does provide some assistance for this though, which is worth pointing out.
You may find a file in PROJECT_ROOT/setup named sun-resources.xml or glassfish-resources.xml. This depends on how you created some of the content of your app...
This file is formated to be input to the GlassFish Server's asadmin subcommand add-resources.
