Cannot start Alfresco after install

[mjohngren]

Hi, I have seen similar questions to mine on the forum but do not see a clear answer.

I have installed alfresco on linux and am running alfresco.sh and get the following response:

[root@sparkpress alfresco]# ./alfresco.sh start
Using CATALINA_BASE:   /opt/alfresco/tomcat
Using CATALINA_HOME:   /opt/alfresco/tomcat
Using CATALINA_TMPDIR: /opt/alfresco/tomcat/temp
Using JRE_HOME:       /usr/bin/java
[root@sparkpress alfresco]#‍‍‍‍‍‍

Alfresco does not start.

When I check catalina.out, I see only the following:

[root@sparkpress logs]# more catalina.out
/opt/alfresco/tomcat/bin/catalina.sh: line 273: /usr/bin/java/bin/java: Not a directory‍‍

Obviously this should just say /usr/bin/java, and I have set the JAVA_HOME variable properly:

[root@sparkpress alfresco]# echo $JAVA_HOME
/usr/bin/java‍‍

So I am not sure where the incorrect /usr/bin/java/bin/java is coming from.

Can anyone please help with this?  Thank you!

Just set 'JAVA_HOME' to be /usr

i.e. /usr/bin/java/bin/java = wrong
/usr/bin/java (correct bit) - /bin/java (extra wrongness) = /usr (what you should set your JAVA_HOME to be)

[mjohngren]

Thanks.  I just tried that but still get the same result - catalina.out still says the same thing.  I also tried putting the export command that sets JAVA_HOME into alfresco.sh instead of .bash_profile, also with no change.  If I remove this altogether then the script says it can't run because JAVA_HOME is not set - I thought maybe it was already getting set somewhere else and so the two versions were getting combined.

What else can I do to track this down?

$JAVA_HOME must be the path for the JDK, not the path for the java executable. Then, $JAVA_HOME/bin should be added to $PATH. Are you sure you have a JRE installed ?
What do you get when you type

ls -al /usr/bin/java‍

and

/usr/bin/java –version‍

?

If you run /usr/bin/java do you get any output? The symlink for /usr/bin/java may exist but you might not have a JVM installed yet

[mjohngren]

Thanks, here are the results.  I installed the JDK prior to installing Alfresco, and that install seemed to go fine.

[root@sparkpress ~]# ls -al /usr/bin/java
lrwxrwxrwx  1 root root 26 Jul 11 21:02 /usr/bin/java -> /usr/java/default/bin/java‍‍

[root@sparkpress ~]# /usr/bin/java -version

[root@sparkpress ~]# /usr/bin/java

    -d64          use a 64-bit data model if available
    -client       to select the "client" VM

…. etc., etc…‍‍‍‍‍‍‍‍‍‍‍‍‍

I appreciate the assistance!

Try setting your JAVA_HOME to your jdk directly

Mine is set to: /usr/java/jdk1.5.0_11/ but will vary depending on your jdk

[root@sparkpress ~]# ls -al /usr/bin/java
lrwxrwxrwx  1 root root 26 Jul 11 21:02 /usr/bin/java -> /usr/java/default/bin/java‍‍

I presume that /usr/java/default is also a symbolic link. You could set JAVA_HOME to /usr/java/default in your .bash_profile

export JAVA_HOME=/usr/java/default‍

and I suggest you update the PATH as well

export PATH=$JAVA_HOME/bin:$PATH‍

[makoildha]

Add an export statement to your 'alfresco.sh' as below:
export JAVA_HOME=/usr

and try that - it worked for me.
Setting it at the terminal before running the alfresco meant it didn't work just as you say.

Thanks for all the suggestions.  jboggs's tip (setting JAVA_HOME directly to the JDK directory) got me past the error I was getting, so that suggests something amiss in the symlinks, and I'll see if these additional suggestions help fix that.  I had earlier tried putting the export statement into alfresco.sh, but that didn't change anything.

So now, I'm on to the next error!    This is what catalina.out is now telling me:

Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.‍‍‍

I am using a hosted virtual linux server, where I have root access but I think there is only 256MB of dedicated memory.  If I lower the maximum heap size for Java, will that fix this, or is there a minimum amount of memory required for Java/Tomcat/Alfresco to run?

Also, where do I change the max heap size?
