hi

i have a headless node on a raspi. now i would like to update. but i don't want to mess up my running system.

how do i update to nrs-v1.11.3? i can connect to the raspi with ssh.

do i just have to save my nxt.properties?

then wget https://bitbucket.org/JeanLucPicard/nxt/downloads/nxt-client-1.11.3.zip
unzip nxt-client-1.11.3.zip
replace nxt.properties and start up again?

thanks for the help.

Code:

kill -15 `pidof java`

to safely shut down NXT. Give it a minute to exit. 'ps auxw | grep java' to make sure it's exited.

mv nxt nxt.old
wget https://bitbucket.org/JeanLucPicard/nxt/downloads/nxt-client-1.11.3.zip
unzip nxt-client-1.11.3.zip
cp nxt.old/conf/nxt.properties nxt/conf/
mv nxt.old/nxt_db nxt/
rm -rf nxt.old

thank you. but now the server just stops.

thats the config:

nxt.myAddress=nxtpi.duckdns.org
nxt.apiServerHost=0.0.0.0
nxt.allowedBotHosts=*
nxt.keyStorePath=keystore
nxt.keyStorePassword= --------------------
nxt.apiSSL=true
nxt.dbUrl=jdbc:h2:/home/pi/usbdrv/nxt_db/nxt;DB_CLOSE_ON_EXIT=FALSE;MVCC=TRUE;M$

[lurker10]

thank you. but now the server just stops.

It complains about
nxt.dbUrl=jdbc:h2:/home/pi/usbdrv/nxt_db/nxt;DB_CLOSE_ON_EXIT=FALSE;MVCC=TRUE;M$

I don't know what the correct format for that setting should be, but you may try to symlink the blockchain directory on the external drive instead of using this setting:

Code:

ln -s /home/pi/usbdrv/nxt_db /home/pi/nxt/nxt_db

you found the problem. after i deleted the line in nxt.properties it works.

BUT before the update it worked with this.
nxt.dbUrl=jdbc:h2:/home/pi/usbdrv/nxt_db/nxt;DB_CLOSE_ON_EXIT=FALSE;MVCC=TRUE;M$

 

EDIT: You found the problem thank you. i cant read these logs. now i have found the solution.

this one worked with  1.11.2

nxt.dbUrl=jdbc:h2:/home/pi/usbdrv/nxt_db/nxt;DB_CLOSE_ON_EXIT=FALSE;MVCC=TRUE;M$

and this one works with  1.11.3

nxt.dbUrl=jdbc:h2:/home/pi/usbdrv/nxt_db/nxt;DB_CLOSE_ON_EXIT=FALSE;MVCC=TRUE;MV_STORE=FALSE

i checked nxt-default.properties and there the part at the end was different.

Companies starting to get ready for Ardor i really am liking this Janus team and the nxt software. Does this community  support bigger projects like them or are they just marketing themselves so far?

This is great, you added to the knowledge base of NXT node operations!
I never used that setting in my nodes.

Hopefully NXT can return to the expensive price at that time in 2014.

Bought my first 600k nxt and buying couple assets. This blockchain is the only one my friends been whispering about lately.

Be sure to run a node and start forging

Do i have to run a node to forge? If i dont run a node and just forge does it still help the blockchain or no?

You can forge on a private node, this is still a node, just not a public one.
You help the blockchain when you forge. The more forging power, the more secure is the blockchain.

Starting the Nxt NRS client makes you forge. You need to have it open though to keep forging.

You can also run it on rasp Pi or Odroid and keep it 24/7 powered by solar panel with battery.

Also you can lease your balance to another forger.
