Symptoms

JIRA won't boot up after migrating it from a server to another. When trying to start JIRA, the following error will occur:

/opt/atlassian/jira/jre/bin/java: No such file or directory

When running the command file /opt/atlassian/jira/jre/bin/java, the following output may be displayed: 

# file /opt/atlassian/jira/jre/bin/java
/opt/atlassian/jira/jre/bin/java: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, not stripped

Indicating the java command does exist but can't be executed.

Cause

This is probably occurring because the new server is a 64 bit Linux, when the old one is a 32 bit one – or vice-versa. 

Resolution

• Browse to www.atlassian.com and download the JIRA version according to your operational system and architecture.
  You may need to re-move the old JIRA installation package and install a new one.

  OS-related questions are out of the support scope, so you may need to contact the OS vendor to get any further assistance on the server side.
