I have problem starting the glassfish server, i'm working on Oracle database EX and Oracle APEX, but while installing the glassfish i had a problem with the the java runtime VM, and after i fixed it, it won't recognize the JDK.
And i managed to install it though, but after i tried to start the application server, it just won't start
I had this message while installing the glassfish, and i selected the jdk file and it worked, maybe this is the problem?
And this is what i got when a tired to start the server application

DNN Upgrade error from 9.1 to 9.3.2 : After upgrade we observe that if we reboot server and immediately try to access the web site then we get error like 'Connection To The Database Failed'.This is happen only first time after server reboot. once we start receiving this error after then we continue receive this error irrespective of how many times we hit website. It is exists till we do IIS Restart or Application pool recyle manually.
Because of this issue we have paused server reboot schedule as well.
Please guide how to overcome from this.
Just a guess, but is it possible that SQL Server starts up slowly after the reboot.
Try waiting 5 minutes before going to the website.
I'm actually a bit surprised that you have this on a DNN 9 installation. I haven't seen it myself as of DNN 8.
I recall solving that by changing the startup type for IIS (in the services MMC) from "Automatic" to "Automatic (Delayed)". That should give SQL Server a decent chance to be started before IIS is.
You could also try to configure the IIS service being dependent on SQL Server (if both IIS and SQL Server are installed on the same machine):
sc config W3SVC depend=MSSQLSERVER
Take care, if you are using a named instance as in the SQL Server Express standard installation, the name could be MSSQL$SQLEXPRESS or whatever instead of MSSQLSERVER. Have a look at the properties of the service to find out.
Trying to connect to localdb using Database tab in Rider.
I adding SqlServer jTds and Rider shows this error
Connection to SunEngineDb1 failed. [08S01] Network error IOException:
.\pipe\MSSQL$LOCALDB#E65C6709\sql\query (Can not find the specified
file)
What am I missing, and how it can be solved?
It is ASP.NET Core 2.0 project with localdb database on development. If I run it it works perfectly including database connect.
Well, finally we discovered the problem. It is the mistake in the driver we provide. To have this issue fixed urgently, delete the file \config\jdbc-drivers\jdbc-drivers.xml and restart the IDE. Then, please, refresh your driver to 1.3.1.1 or just put [latest] there.
After I reinstalled my computer I could no longer connect to any database in NetBeans IDE 8.0.2, even the sample. It shows "Connecting to database, please wait..." but nothing ever happens. All the time there's just "Starting the Java DB Server". No errors. It just doesn't work. I can't even create my own database.
I used different version of jdk and it works.
I installed Oracle database 12c for the first time. I followed correctly all the steps and installed it on Windows 7 64 bits, but when I click on SQL Developer and try to create a new connection, I put in the informations like Username and password, and finnaly click on TEST button, I get this error message: "The Network Adapter could not establish the connection".
I dont know what to do anymore, I read tutorials and cant solve that error. Also, when I open SQL Developer, i get a message saying Im using a java version that is not supported by Oracle Database, Im using java 1.8 and it says I should use from 1.6 to 1.7 only. im not sure if that is causing something bad but it seems fine because I can go further using the SQL Dev. So, what should i do? Thank you very much!
Here are some things to check:
Ensure that the TNSNAMES.ORA file is properly configured to reference the database. Check for the SID, host name, and port number (typically 1521).
Check whether you can connect directly from the server, such as with SQL PLus. This should isolate whether it's a server or client problem.
Ensure that the Listener service on the server is running. Check that LISTENER.ORA is properly configured.
I encountered a situation in the past where client PCs could not connect. I found that by deleting (or renaming) the SQLNET.ORA file, the connection could be made.
Good luck.
Execute
tnsping <db_name>
from command prompt.
You will see, if listener is running and tnsnames.ora is configured properly.
Run with Windows PowerShell or Command Prompt (Admin) :
lsnrctl start
I am developing web application using Tomcat 7 and connecting to a MSSQL 2008 DB.
While executing a DB operation from any Java console based application, it succeeds. Same code fails to execute while performing same operations from web application with the message "No suitable drivers found". We are using sqljdbc4
URL private String url = "jdbc:sqlserver://10.100.41.232;databaseName=iptvdb;";
Not able to understand the this strange behaviour. Any workarounds?
Also tried with : port 1433 but it's still not working.
That error means it cant find the JDBC driver on your classpath. Do you have the JDBC driver? You need to have the MySQL JDBC drivers. If you dont have it, it can be downloaded from the MySQL website.
If you do have the driver or have downloaded it, make sure it is in the correct place. It needs to be placed on your classpath. This usually means one of two places
With your Struts application under the WEB-INF/lib folder
With the application server. For tomcat this is usually in $CATALINA_HOME/lib
