Other Linux Installation examples available.

Any user with access to system tools can reset the admin password with a web browser.

Any person with access to the SQL server can change the admin password to another users password

select object_id, username, password from users where username = 'admin' or username = '$ME';
update users set password = '$PASS' where object_id = '$ID';

For example

update users set password = 'P3b*cH.5fOBTJl5ELM)W' where username = 'admin';

Example scripts for a High availability install of Noodle 7.08.05+.

1) Install 3+ Linux instances with password-less key authentication, run the following on each (using real IPs and domains);

hostname must match domain name.

IP1= #dn1
IP2= #dn2
IP3= #dn3
IP="$(ip addr show | grep "inet " | grep -v | head -n 1 | perl -pe 's/\/.*//g;s/.* //g')"

apt update
apt -y dist-upgrade
apt -y install ceph-fuse openjdk-11-jre
apt -y purge snapd landscape-common
apt -y autoremove

#if public domains are not in use;
echo "
$IP1 dn1 dn
$IP2 dn2 dn
$IP3 dn3 dn
" >> /etc/hosts

2) Install Ceph from the admin node (all nodes will wipe /dev/xvdb);

(Ubuntu 20.04 requires this patch first.)

apt-get -y install ceph-deploy

ceph-deploy new dn1 dn2 dn3
ceph-deploy install dn1 dn2 dn3
ceph-deploy mon create-initial
ceph-deploy admin dn1 dn2 dn3
ceph-deploy mgr create dn1 dn2 dn3
for N in dn1 dn2 dn3 ; do
        ceph-deploy osd create $N --data /dev/xvdb
ceph-deploy mds create dn1 dn2 dn3
for N in dn1 dn2 dn3 ; do
        ceph-deploy mon add $N
ceph osd pool create ${POOL}_data 16
ceph osd pool create ${POOL}_meta 16
ceph fs new ${POOL}_fs ${POOL}_meta ${POOL}_data
for N in dn1 dn2 dn3 ; do
	ssh $N "echo 'none /opt/Noodle/FSDB fuse.ceph,_netdev,defaults 0 0' >> /etc/fstab && mount -a"

3) Install CockroachDB on all nodes;

cd /opt
wget -qO- | tar  xvz
cp /opt/Noodle/cockroachdb.service /lib/systemd/system/
perl -pi -e "s/\$IPS/${IP1},${IP2},${IP3}/g;s/\$IP/${IP1}/g" /lib/systemd/system/cockroachdb.service
systemctl enable cockroachdb
systemctl start cockroachdb

4) initialize CockroachDB from the admin node;

./cockroach-v19.2.2.linux-amd64/cockroach init --insecure --host=${IP}
echo "CREATE USER noodleuser; CREATE DATABASE noodledb WITH ENCODING = 'UNICODE'; GRANT ALL ON DATABASE noodledb to noodleuser;" | ./cockroach-v19.2.2.linux-amd64/cockroach sql --insecure --host=${IP}:26257

5) Install Noodle on all nodes;

cd /opt
tar -xf Noodle.tar.gz
cd ./Noodle
echo "NoodleNodes[] = ${IP1}, ${IP2}, ${IP3}
FSDB = /opt/Noodle/FSDB" >> conf/
perl -pi -e 's/^(DatabaseManager.DB.intranet.Connection.Url = ).*/$1"jdbc:postgresql:\/\/'"$IP"':26257\/noodledb"/g' conf/
cp noodle.service /lib/systemd/system/
perl -pi -e 's/postgreql.service/ cockroachdb.service/g' /lib/systemd/system/noodle.service
systemctl enable noodle
systemctl start noodle

letsencrypt offers free HTTPS certificates with the limitation that you need to set them up to auto renew every ~3 months. Below are some example scripts that last of which should be called from cron.



. /opt/Noodle/
apt install -y certbot
systemctl disable certbot
mkdir $DIR
certbot register --agree-tos --no-eff-email -m "$EMAIL"
certbot certonly --webroot \
	--webroot-path $DIR \
	--cert-name "$DOMAIN" \
	-d "$DOMAIN"


systemctl restart noodle.service


. /opt/Noodle/
certbot renew --webroot \
	--webroot-path $DIR \
	--cert-name "$DOMAIN" \
	--deploy-hook /opt/Noodle/

Currently Noodle must be restarted to reload the keystore.

  • 1995; Sun Microsystems created Java
  • 2006; Sun released Java under the GPL

  • 2019; Oracle stopped releasing security updates for LTS releases under a permissive license

OpenJDK is the upstream for all Java builds but does not release builds itself, so there are now many java distributions, some with additional patches. In addition to the Linux distributions (Debian/Ubuntu, Fedora/RedHat, Arch, openSUSE, etc) building off OpenJDK for their package managers the following are available;

BuildPermissivePureCommercial Support
Adoptium (AdoptOpenJDK) / IBMYesOptionalYes
Microsoft (JClarity)YesNoNo
Azul ZuluYesNoYes
Amazon CorrettoYesNoYes
RedHat for WindowsYesNoYes

Windows users can subscribe to releases on github until the windows store catches up with Linux repositories since the year 1998

Other Linux Installation examples available.

  • Upgrade
  • Drive Space low
    • Add more storage space (a SSD preferably) (can be done without service interruption if you are using a Logical Volume Manager)
  • Out of RAM
    • Add more Memory
    • This warning is not yet supported for MSSQL or remote databases.
  • Index Queue not empty
    • Can be ignored if intermittent small numbers
    • Contact support if large numbers persist
  • HTTP pool too full
    • in server.xml increase HTTP pools like to at least double the number of active users. (you may also have a connection per port HTTP and HTTPS)
  • DB pool full
    • The default setting of 30 in for DatabaseManager.DB.intranet.Connection.MaxPoolSize is already fairly high so normally this is an indication that the SQL server getting slow.
    • maintenance: rebuild the indexes
    • replace spinning storage with SSD (LVMCache supports a mix).
    • Increasing the number without ensuring the DB pool was filled because of volume (not latency) will likely cause out of memory or deadlock errors on the database instead of just slowness.
  • User limit
    • Remove users from the imported Active Directory security group or contact us for a larger License.
    • Additionally and optionally delete disabled users that will not be added back to the imported Active Directory security group.
