Increasing Java Heap Memory Size on Openfire 4.0.3 (Slackware 14.0 and Debian 8.5)

Slackware 14.0
Openfire Version : 4.0.3
Installed location : /opt/openfire

increasing java heap memory size
creating openfire.vmoptions

root:# touch /opt/openfire/bin/openfire.vmoptions

and at this value to openfire.vmoptions (mine is max 1GB), change value as needed.

root:# mcedit /opt/openfire/bin/openfire.vmoptions
-Xms512m
-Xmx1024m

Testing

Start openfire and grep it to see if variable inside openfire.vmoptions used or not.

root:# ps ax | grep -i openfire

Openfire RSA Certificate issue (RSA certificate not valid)

I got this error after moving my openfire database from Slackware 14.0 to Debian 8.5,

but it just simple problem and openfire already have this solution, just follow this step to resolve issue. Now open TLS/SSL Crtificates tab, and Delete ALL certificates there.

Now you should get new certificates

And everything back to normal

Moving Openfire 4.0.3 Embedded Database from Slackware 14.0 to Debian 8.5

Slackware 14.0

embedded-db location is at  /opt/openfire/embedded-db/ that because im installing Openfire at directory /opt

root:# ls -al /opt/openfire/embedded-db/
total 172672
drwxr-xr-x  2 root root      4096 Oct 24 13:26 ./
drwxr-xr-x 12 root root      4096 Sep  5 09:52 ../
-rw-r--r--  1 root root        16 Oct 24 13:35 openfire.lck
-rw-r--r--  1 root root   4236557 Oct 24 13:35 openfire.log
-rw-r--r--  1 root root       410 Oct 24 13:26 openfire.properties
-rw-r--r--  1 root root 172378422 Oct 24 13:26 openfire.script

Basicly embedded openfire database is only script, yes it just one script contains many SQL command, and that script is openfire.script inside directory embedded-db.

Okay, before we doing backup for directory embedded-db, we must stop openfire service.

root:# /etc/rc.d/rc.openfire stop

Then zip it using zip tool

root:# zip -r embedded-db.slackware.zip embedded-db/
updating: embedded-db/ (stored 0%)
  adding: embedded-db/openfire.properties (deflated 42%)
  adding: embedded-db/openfire.script (deflated 89%)
  adding: embedded-db/openfire.lck (stored 0%)

And you will get embedded-db.slackware.zip (you can use another name) and copy embedded-db.slackware.zip  to Debian 8.5.


Debian 8.5 
embedded-db location is at /usr/share/openfire/ but linked to /var/lib/openfire/embedded-db/

root@triton:~# ls -al /var/lib/openfire/embedded-db/
total 21104

-rw-r--r-- 1 openfire openfire  8706332 Oct 23 08:20 openfire.script

Okay, before we doing backup for directory embedded-db, we must stop openfire service.

root@triton:# /etc/init.d/openfire stop

Then zip it using zip tool

root@triton:/var/lib/openfire# zip -r embedded-db.debian.zip embedded-db
  adding: embedded-db/ (stored 0%)
  adding: embedded-db/openfire.properties (deflated 43%)
  adding: embedded-db/openfire.script (deflated 58%)

Delete directory embedded-db

root@triton:/var/lib/openfire# rm -Rf embedded-db

root@triton:/var/lib/openfire# ls -al
total 22484
drwxr-x---  4 openfire openfire     4096 Oct 23 09:05 .

drwxr-x--- 18 openfire openfire     4096 Sep  8 00:07 plugins

Now unzip embedded-db.slackware.zip

root@triton:# unzip embedded-db.slackware.zip

make it become openfire owner with this command

root@triton:/var/lib/openfire# chown openfire:openfire embedded-db -R

Start debian openfire with this command

root@triton:# /etc/init.d/openfire start

open your openfire server at : http://your.openfire.url:9090 and change this value

server --> server manager --> system properties -->xmpp.domain
server --> server manager --> system information-->edit properties (button - left bottom) --> server name

After moving database from one server to another server maybe you will get RSA Certificate issue (RSA certificate not valid), follow this step to resolve it.
