Question

Setting JAVA path in Appian

Hi,

In my Linux server with appian 20.4 installed, 

the following are the details in the "profile" file in /etc folder --
export JAVA_HOME=/data-01/appian/203/appian/java ---- actually this path does not exist in the server
export PATH=$JAVA_HOME/bin:$PATH:

But when I run the command 

echo $JAVA_HOME, I find this --

/usr/lib/jvm/jdk1.8.0_191

I tried removing the  java folder, in the above path(/usr/lib/jvm/jdk1.8.0_191) and stopping my Appian services, (firstly the Tomcat) but the jsp commands are unrecognisable. As soon as I restored the Java at the above path, everything resumed fine.

The JAVA_HOME in the profile file refers to a different path while the actual JAVA location used by my services seems to be different.

Can any one guide me to change the JAVA_HOME path?

Can I point my Appian services to use the the Java in this path (/data-01/appian/204/appian/java)? If so where should I set the path for my Appian services to point to this path?

Thanks,

Chetana

Based on what you posted, this should work - no?  You also need to reload your shell for the change to take effect. 

export JAVA_HOME=/data-01/appian/204/appian/java
export PATH=$JAVA_HOME/bin:$PATH:

Try running the following after making the update to the file:

bash --login
java -version

Hi Mathieu,

I have executed the above commands, restarted my services. and when I check echo $JAVA_HOME

it is pointing to the new path(/data-01/appian/204/appian/java). And my envi is up and running.

But during the restart when I checked the logs , I found this

Do I need to change the path elsewhere too?
