Thanks for your great help...!
Dear Marcos, As you suggested me to check the file size, i checked the file size and it was full.. I have removed all unwanted data from the 'var' file and repaired the table using repair query.. now i can successfully run query on table..

Database pool full.
Dear All,
I am developing an application on resin-2.1.9 web server.
Connection to MYSQL Database is using JNDI. JNDI connection code is written in a class
called DBService.
I am instantiating DBService class where ever i need database connection and getting
connection using getConnection() method.
when user start working on application, i m getting following errors,
Class:DBService. Method:getConnection() cann't open connection with full database
pool(30)
Class:MonthReport. Method:SelectReportDetailNull() cann't open connection with full
database pool(30)
it sounds like database pool is full, Whether i need to increase the pool size or
optimize code in DBService database connection class.
for your reference below code performs database connection.
--
public Connection getConnection()
{
java.sql.Connection con = null;
javax.sql.DataSource ds=null;
try{
Context initCtx = new InitialContext();
Context envCtx = (Context) initCtx.lookup("java:comp/env");
ds= (DataSource)envCtx.lookup("jdbc/training");
con = ds.getConnection();
}catch(Exception e){
System.out.println("Class : DBService, Method :
getConnection()"+e.getMessage());
}
return con;
}//end of getConnection method
-
Your advice will be great help to optimize my application.
Thanks in advance.
Regards,
Viru
Re: Database pool full.
Dear Max,
Yah, this problem occures after visiting some pages,
to use #1 strategy, whether I need to do any changes in configuration or is
there any other way?
Thanks for your suggestions & immediate response,

Re: Database pool full.
Thanks max for your suggestions, Yah, there was a connection leak in a mthod, so that leades to system slow down. Now it's OK, I am monitoring my application performance , then, we are using Resin connection pool class. any more suggestions?
