BIuser showing socket connection error on SpagoBI

We have already covered in our previous article about SpagoBI installation in Linux and working properly. When i’m trying to login biuser its through the below error message after login into biuser because i have missed to give executable permission to database directory (I’m using HSQL database). Here i’m going to show you, how i have identified the root causes of issue.

The following items have errors:
Grid (id = 552):
+ An exception occurred during processing. Please see the following message for details:
Cannot open the connection for the driver: org.eclipse.birt.report.data.oda.jdbc.
    org.eclipse.birt.report.data.oda.jdbc.JDBCException: There is an error in get connection, socket creation error.
.
.
Table (id = 469):
+ An exception occurred during processing. Please see the following message for details:
Cannot open the connection for the driver: org.eclipse.birt.report.data.oda.jdbc.
    org.eclipse.birt.report.data.oda.jdbc.JDBCException: There is an error in get connection, socket creation error. 

1) How to access the SpagoBI on browser ?

5) How to identify ?

It seems database not connecting that’s why you will get below error message. I’m going to run the SpagoBIStartup.sh shell file to check what will happen.

# ./SpagoBIStartup.sh
.
./SpagoBIStartup.sh: 21: ./SpagoBIStartup.sh: ./start.sh: Permission denied

Yes, it’s through some error on line 21 on that file.

6) Checking SpagoBIStartup.sh shell file ?

Use your favourite text editor to open the file and navigate to line number 21

# nano SpagoBIStartup.sh

#!/bin/sh

# resolve links - $0 may be a softlink
PRG="$0"

while [ -h "$PRG" ] ; do
  ls=`ls -ld "$PRG"`
  link=`expr "$ls" : '.*-> \(.*\)$'`
  if expr "$link" : '/.*' > /dev/null; then
    PRG="$link"
  else
    PRG=`dirname "$PRG"`/"$link"
  fi
done
 
PRGDIR=`dirname "$PRG"`
cd $PRGDIR
echo $PRGDIR

cd ../database
./start.sh &
cd ../bin
./startup.sh &
exit

In line number 21, its trying to start, start.sh file under database directory but there is no permission to start the file that’s why you are getting that error message.

7) Checking database directory files ?

Navigate to database directory and check the start.sh file. Yes, its seems the start.sh file not having executable permission to start the hsql database.

# cd database
# ls -lh
-rw-rw-r-- 1 magesh magesh   89 Jun 19  2012 start.sh

I’m going to give executable permission to start.sh file. Check the start.sh file now.

# chmod 755 start.sh

8) Run the SpagoBIStartup.sh file to start the server ?

I’m going to run the SpagoBIStartup.sh file to check the status.

# ./SpagoBIStartup.sh
.
