I am trying to run the command line tutorial for Cassandra and am running into an error. This is what I ran.
bin/geomesa-cassandra ingest --contact-point localhost --key-space mykeyspace --catalog mycatalog --converter example-csv --spec example-csv examples/ingest/csv/example.csv
This is what I get in return.
What would cause this?
You need to specify the contact point as host:port. See the documentation for the connection parameters. I opened a ticket to improve the error handling for an incorrectly formatted contact point, so that the error will be more obvious.
Thanks,
My system is:
Mac os X 10.9 Mavericks
Oracle JDK 7u45 (the latest)
Glassfish 3 and Glassfish 4 is the same
I go to the download page of glass fish and download the zip.
i do init the glassfish domain using: asadmin start-domain domain1
Go to localhost:4848 and the console still loading...
i review the glassfish log in this point, and the last message is:
javax.enterprise.system.core.com.sun.enterprise.v3.admin.adapter|_ThreadID=83;_ThreadName=Thread-2;|The Admin Console application is loaded.|#]
the message appears to be fine.
When i refresh the page (because doesn't refresh itself), it redirects me to http://localhost:4848/common/index.jsf with status 404.
if i review again the glass fish log, the message is:
org.apache.jasper.servlet.JspServlet|_ThreadID=84;ThreadName=Thread-2;|PWC6117: File "/Users/juvinao/glassfish4/glassfish/lib/install/applications/_admingui/common/index.jsp" not found|#]
this just happen in my mac, after the mavericks upgrade.
in others computers and OSs, everything go fine.
i was googling for info about this issue, but even here in stack overflow i had found the answer.
Thanks.
the only way that i resolved the issue, is that when the console redirect me to
http://localhost:4848/common/index.jsf
i put the url
http://localhost:4848/login.jsf
but always i have to do this. next i have access to login page and admin console.
i had the same problem, but instead of console, my app was behaving like this.
solution: update "glassfish/glassfish/modules/javax.faces.jar" (2.2.0) with 2.2.4
still don't know why or in which way these things are linked...
Ensure that the file is not missing and you have enough rights to access it or maybe modify.
Disable Automatic Update Checks
Rename $GLASSFISH_INST/glassfish/modules/console-updatecenter-plugin.jar to console-updatecenter-plugin.jar.disabled
Would any one please explain how to check webdriver server log? The log we used to see by running selenium server from command line. I am using firefox driver with latest stand alone server. I tried this link to create firefox profile with preferences but I didnt get any result out of it.
Please share your idea or any work around. Thanks
you can use selenium-standalone-server-2.15.0
In this version they make the loggers as default. So that you can find logs on your editor(Eclipse) console itself.
I am trying to use the H2 database from a Java application.
I created the database and its tables through the H2 Console and then I try to connect from Java using
Connection con = DriverManager.getConnection("jdbc:h2:~/dbname", "username", "password");
However I receive the following error:
Exception in thread "main" org.h2.jdbc.JdbcSQLException: Database may be already in use: "Locked by another process". Possible solutions: close all other connection(s); use the server mode [90020-161]
I tried to delete the dbname.lock.db file but it is automatically re-created.
How can I unlock the database to use it from my Java program?
H2 is still running (I can guarantee it). You need to use a TCP connection for multiple users such as ->
<property name="javax.persistence.jdbc.url" value="jdbc:h2:tcp://localhost/C:\Database\Data\production;"/>
OR
DriverManager.getConnection("jdbc:h2:tcp://localhost/server~/dbname","username","password");
It also means you need to start the server in TCP mode. Honesetly, it is pretty straight forward in the documentation.
Force kill the process (javaw.exe for Windows), and make sure that any application that might have started it is shut down. You have an active lock.
I had the same problem.
in Intellj, when i want to use h2 database when my program was running i got the same error.
For solve this problem i changed the connection url from
spring.datasource.url=jdbc:h2:file:~/ipinbarbot
to:
spring.datasource.url=jdbc:h2:~/ipinbarbot;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE
And then my problem gone away. now i can connect to "ipinbarbot" database when my program is.
If you use Hibernate, also don't forget to have:
spring.jpa.hibernate.ddl-auto = update
goodluck
I'm using h2db with a test T24 tafj application, I had the same problem but I managed to resolve it by identifying the application that is running h2 (launched when I attempted to setup a database connection).
ps aux|grep java
will give output as:
sysadmin 22755 3.2 0.1 5189724 64008 pts/3 Sl 08:28 0:00 /usr/java/default/bin/java -server -Xmx2048M -XX:MaxPermSize=256M -cp h2-1.3.175.jar:/r14tafj/TAFJ/dbscripts/h2/TAFJFunctions.jar org.h2.tools.Server -tcp -tcpAllowOthers -baseDir /r14tafj/t24/data
now kill this with its process id:
kill -9 22755
and at last remove the lock file:
rm -f dbname.lock.db
I got clue from Saman Salehi above.
My usecase:
Preparing REST application for client-side load balancing(running two JVM instances of REST). Here my MVC application will call this REST application that has ActiveMQ backend for DATA.
I had the problem when I ran two instances of REST application in eclipse and trying to run both instances at the same time with the following configuration
spring.datasource.url=jdbc:h2:file:./Database;
spring.jpa.properties.hibernate.hbm2ddl.auto=update
After adding DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE
spring.datasource.url=jdbc:h2:file:./Database;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE
Both instances are running and showing in Eureka dasboard.
Don't close the database when the VM exits : jdbc:h2:;DB_CLOSE_ON_EXIT=FALSE
Multiple processes can access the same database without having to start the server manually ;AUTO_SERVER=TRUE
Further reading:
http://www.h2database.com/html/features.html
You can also visit the "Preferences" tab from the H2 Console and shutdown all active sessions by pressing the shutdown button.
Simple step: Go to the task manager and kill the java process
then start your apllication
You can also delete file of the h2 file database and problem will disappear.
jdbc:h2:~/dbname means that file h2 database with name db name will be created in the user home directory(~/ means user home directory, I hope you work on Linux).
In my local machine its present in: /home/jack/dbname.mv.db I don't know why file has a name dbname.mv.db instead a dbname.
May be its a h2 default settings.
I remove this file:
rm ~/dbname.mv.db
OR:
cd ~/
rm dbname.mv.db
Database dbname will be removed with all data. After new data base init all will be ok.
If you are running same app into multiple ports where app uses single database (h2), then add AUTO_SERVER=TRUE in the url as follows:
jdbc:h2:file:C:/simple-commerce/price;DB_CLOSE_ON_EXIT=FALSE;AUTO_RECONNECT=TRUE;AUTO_SERVER=TRUE
I ran into similar problems running with ORMLite from a web application. I initially got stuck on the syntax to use server mode in the url. The answers above helped with that. Then I had the similar user/password error which was easier to figure out. I did not have to shut anything down or erase any files. The following code worked:
protected ConnectionSource getConnectionSource() throws SQLException {
String databaseUrl = "jdbc:h2:tcp://localhost/~/test";
return new JdbcConnectionSource(databaseUrl,"sa","sa");
}
To use H2 in server mode on wildfly, I Modifed connection-url in standalone.xml
<datasource jndi-name="java:jboss/datasources/ExampleDS" pool- name="ExampleDS" enabled="true" use-java-context="true">
<connection-url>jdbc:h2:tcp://localhost/~/test</connection-url>
…
</datasource>
Identify the H2 process id and kill it. For mac
ps -ef|grep h2
Then get the process id and kill it.
kill -9 PID
According H2 Database Tutorial you can run the H2 Database in three different modes:
Server mode:
jdbc:h2:tcp://localhost/~/test
When using H2 db in server mode (also known as client/server mode) all data is transferred over TCP/IP. Before application can use H2 Database in server mode, you need to start the H2 DB within the same or another machine.
Embedded mode:
jdbc:h2:~/test
H2 db in embedded mode will be faster but the downside of it is that no other process can access the Database. In the above connection string, the Data will be saved into the ‘test’ folder, under the user’s home directory.
Mixed mode:
The mixed mode combines some features of the embedded and the server mode. The first application connecting to the H2 db does that in embedded mode, but at the same time it starts a server so that other applications can concurrently access the same data, even from different processes.
jdbc:h2:/data/test;AUTO_SERVER=TRUE
When using automatic mixed mode, you can share the JDBC URL for all applications using the DB. By default the server uses any free TCP port. The port can be set manually using AUTO_SERVER_PORT=9090.
Ran into a similar issue the solution for me was to run fuser -k 'filename.db' on the file that had a lock associated with it.
Hope this helps!
I was facing this issue in eclipse . What I did was, killed the running java process from the task manager.
It worked for me.
In your application.properties file > edit the datasource into:
spring.datasource.url=jdbc:h2:file:C:/temp/test;DB_CLOSE_ON_EXIT=FALSE;AUTO_SERVER=TRUE
Happy coding!
answer for this question => Exception in thread "main" org.h2.jdbc.JdbcSQLException: Database may be already in use: "Locked by another process". Possible solutions: close all other connection(s); use the server mode [90020-161]
close all tab from your browser where open h2 database also Exit h2 engine from your pc
For InteliJ: right lick on your database in the database view and choose "Disconnect".
I tried to delete the dbname.lock.db file but it is automatically re-created.
How can I unlock the database to use it from my Java program?
Just add FILE_LOCK=NO;. FILE_LOCK=NO doesn't make dbname.lock.db.
spring.datasource.url=jdbc:h2:file:./testdb/h2;DB_CLOSE_ON_EXIT=false;FILE_LOCK=NO;
The detail for FILE_LOCK reference this.
Using the method NO forces the database to not create a lock file at all
My eclipse used to work fine but now I am no longer the administrator of my computer(I no longer have administrator priveledges) and i see that my already installed and working eclipse is now showing errors in my jsp files of the application which it didn't used to show before..
also I am not able to connect to tomcat server which seperately can be started normally but not inside eclipse.....
Is this something to do with my not being administrator anymore of is it something else....
would highly appreciate the help.....
I have now been able to run my tomcat server without admin previledge but problem of many files showing error still persists.........
the below written jsp code is showing error in all the files....:
<%
pageContext.getRequest().setCharacterEncoding("UTF-8");
String label = pageContext.getRequest().getParameter("rswitb1");
if(label==null)label="";
else label = label.replaceAll("<", "<").replaceAll(">", ">");
%>
I am not able to get what the problem ....
if anyone could help...
The connection to the external tomcat should be using only TCP/IP port 8080, there is no reason why a non-admin user should not be able to do that.
It's possible that your tomcat password has changed (or hasn't been set up at all)
There is a troubleshooting section at the eclipse wiki (if you are using WTP, that is)
First,check out the tomcat server is on: "netstat -an" to
find that whether the port8080 is used(if you didn't assign another server port.).
check out whether the server is on(netstat -an).
Maybe 8080 is used by tomcat.
You'd better reinstall tomcat as non administrator.
