Troubleshooting common connection problems

If you have connection problems after completing the installation, check the following list for possible causes and solutions:

TCP/IP
Before attempting a client-server connection, test the protocol installation to ensure that the connection is installed properly.
The servers
Use the PING command on the server to check that it is running and visible to the client. If the PING command is successful but the TELNET command is not, then there may be a problem with the inet daemon. If the PING command is unsuccessful on the server, you might have a routing or hardware problem.
General problems when connecting to Java
After following the instructions inConfiguring the environment on UNIX, if you are still having difficulties getting DB2 OLAP Server to work with Java, it may be necessary to set startup options for the Java Virtual Machine (JVM). You can make DB2 OLAP Server use specific JVM startup options when it loads the JVM by setting the environment variables ESS_JVM_OPTION1 through ESS_JVM_OPTION9.
Problems with Java on Solaris 1.4.1_06 only
The ESS_JVM_OPTION1 variable is required on Solaris 1.4.1_06 if you are using JVM for custom-defined functions, custom-defined macros, data mining, triggers, or external authentication supplied by Hyperion. You must set an ESS_JVM_OPTION environment variable to use a special Java argument, Xusealtsigs. This requirement applies only to JRE version 1.4.1_06 on Solaris and is not applicable to other JRE versions on Solaris. To set ESS_JVM_OPTION1:

Additionally, ESS_CSS_JVM_OPTION1 is required on Solaris 1.4.1_06 if you are using the security platform supplied by DB2 OLAP Server. You must set an ESS_CSS_JVM_OPTION environment variable to use a special Java argument, Xusealtsigs. To set ESS_CSS_JVM_OPTION1:

Problems with Java on HP-UX
If you have problems connecting to Java on HP-UX, or if DB2 OLAP Server ends abnormally, set the environment variable LD_PRELOAD. Set this variable in a shell script that you design for starting Analytic Services. For example, create a script called startessbase.sh in $ARBORPATH/bin with the following contents (for Bourne or Korn shell):
export LD_PRELOAD=HYPERION_HOME/common/JRE/1.4.1/lib/ 
PA_RISC2.0/server/libjvm.sl 
$ARBORPATH/bin/ESSBASE

Then start DB2 OLAP Server using the startup script:

cd $ARBORPATH/bin ./startessbase.sh

The following example of a startessbase.sh script is for the C shell:

setenv LD_PRELOAD LD_PRELOAD$/home/hyperion/common/JRE/
  1.4.1/lib/PA_RISC2.0/server/libjvm.sl 
$ARBORPATH/bin/ESSBASE
CAUTION:
Setting LD_PRELOAD in UNIX environment scripts such as .profile is not recommended, because side effects may occur.
