ColdFusion 2021 JRE libraries are missing or not compatible

[Dan Mather]

Hi All,

I'm trying to install CF2021 on RedHat 8.7

The installer keeps exiting with the error:

"JRE libraries are missing or not compatible" 

 Initially I thought perhaps my /tmp was not large enough so I enlarged it.

Then thought to set IATEMP to another location with tons of space --still the same error.

I even installed a JRE for the system --still the same error

Is this a problem with running RHEL 8.7 vs 8.5?

Is there something else I should be trying?

Hi Dan,

Can you please try these steps?

1. Type these commands in the terminal: tmp folder location can be anywhere, it is just for reference. 

a.   sudo su

b.   cd /

c.    mkdir tmp2

d.  IATEMPDIR=/home/rhel/tmp
e.  export IATEMPDIR

Priyank,

Yes, I had tried that -I mistyped the variable name in my initial post.  It was IATEMPDIR that I set to another directory with tens of gigabytes of space.

@Dan Mather,  Could you please try this?

./ColdFusion_2021_XXXX_XXXX.bin  LAX_VM  /usr/jdk/xxxx/jre/bin/java

Thanks,

Vikram

Thanks Vikram I was able to install using the LAX_VM and (for good measure) IATEMPDIR.

Just wondering why this issue crops up?

@Dan Mather Glad it worked! One possible reason could be InstallAnywhere picking the incorrect java version. 

Thanks,

Can I pile on here?  My rhel8.7 server has both IPv6 and IPv4 enabled. It seems ColdFusion and Tomcat are both picking IPv6 instead of IPv4.  I added Java options to the jvm.config "-Djava.net.preferIPv4Stack=true -Djava.net.preferIPv4Addresses=true" but they don't seem to have any effect.  Is there another way to have ColdFusion builtin web server use IPv4?

Thanks,

Dan Mather
