Hello Maxim,
thank you for the indoctrination about the using of graphics in emails.
I will do better next time.
My Solution:
The Parameter "serverTimezone" must in the first line of the
Driver-command (where is separated by "&").
It doesn't matter where you put it.
When I put it into the comma-separated-part it's not functionally.
Here's my line in the mysql-persistence.xml:
value="DriverClassName=com.mysql.cj.jdbc.Driver
,
Url=jdbc:mysql://localhost:3306/openmeetings?autoReconnect=true&useUnicode=true&*serverTimezone=Europe/Berlin&*createDatabaseIfNotExist=true&characterEncoding=utf-8
&connectionCollation=utf8_general_ci&cachePrepStmts=true&cacheCallableStatements=true&cacheServerConfiguration=true&useLocalSessionState=true&elideSetAutoCommits=true&alwaysSendSetIsolation=false&enableQueryTimeouts=false&prepStmtCacheSize=3000&prepStmtCacheSqlLimit=1000&useSSL=false&nullNamePatternMatchesAll=true
, maxTotal=100
, maxIdle=100
, minIdle=0
, maxWaitMillis=10000
, TestOnBorrow=true
, poolPreparedStatements=true
, Username=
, Password=" />
Best regards,
René

2 points:
1) no need to share screen-shot to share _text_ :)
2) when I wrote "Could you please check if persistense.xml have all
necessary parameters" I mean:
a) open file in your favorite editor
b) check it's content
If changes made by installer are "disappear", check:
1) if you have only one copy of OM on your VM
2) if you don't have some script rewriting persistense.xml
Additionally after successful installation there should be DB tables,
and these tables shouldn't be empty
BTW are you using MariaDB or MySql?

No way.
At the installation-process it stuck.

Hello René,
after successful installation your mysql_persistense.xml file
should be copied to persistense.xml
Could you please check if persistense.xml have all necessary
parameters?
1) correct DB host/port/name
2) correct DB credentials
3) this additional time-zone parameter

Hm, since a few minutes the " The server time zone value

I had change that after boot there is no GUI.
sudo systemctl set-default multi-user.target
and make a reboot.
After that I get the installation-screen and on the scond
screen with the Database-choice I get the error.
A little bit frustrating.

Hello Maxim,
the result of "timedatectl":

Now I put the parameter you wrote helpful in your last

Here is the fully parameter I actually use, if someone
need it.
<property name="openjpa.ConnectionProperties"

I am a little bit amazed about one thing: To test the
new OM5 I made a lot of times a new virtual machine with
the same Ubuntu 18.04-Installation. I mean that the
the first times the OM-MySQL-Connection runs without
problems. No modification necessary. Anytime the error
Maxim describe occurs, and I dont know why.
Sure, I made something different, but I have no idea
what it can be.
OK, for the moment I am very happy, get a gulp from my
fresh/hot coffee and look forward to test the newest
modification Maxim implemented yesterday in a speed
where I am very surprised.
Maxim: Very good work!
Best regards,
René

Just have tried to change TZ on my test Ubuntu server
to be CEST and:
*sudo timedatectl set-timezone CEST*
Failed to set time zone: Invalid time zone 'CEST'
What is the result of `timedatectl` command on your system?

Hello René,
I'll try to set up VM to test following steps (so
here it is untested)
1) open
${OM_HOME}/webapps/openmeetings/WEB-INF/classes/META-INF/mysql_persistence.xml
2) find <property name="openjpa.ConnectionProperties"
3) add ", serverTimezone=Europe/Berlin" to the
comma separated values
run command line or web installer
