Uyuni Master Java issues on CentOS 8
Hello Java Experts, I am back at trying to get "rhn" to start on Tomcat/CentOS 8. Brief history: OpenSUSE Leap 15.2 comes with a non-standard Java 11 OpenJDK version that integrates com.sun.xml.bind and allows usage by starting Java with the flag "--add-modules java.annotation,com.sun.xml.bind". As CentOS does not have these modules, the following packages need to be added: glassfish-jaxb-api, glassfish-jaxb-core, jaf, istack-commons-runtime. Using the same jars on Leap allows the removal of the module flag and the system starts up without any issues (that I noticed). CentOS also does not show any "class not found" exceptions anymore so it sounds from that perspective, I am good. Unfortunately, now the stack trace below is thrown. I guess this might have something to do with bundle/class version requirements. Can you please give me some suggestions how to best approach the issue resolutions? I am currently testing on a Uyuni installation itself, trying to get it to start. Also any ad-hoc ideas where to focus the issue identification on the stack trace?

Hello Stefan, This error is happening because the configuration property for `db_user` is not set on the rhn.config. I was able to reproduce the same error by commenting this property in my local server. Default location for this file is `/etc/rhn/rhn.conf`. Do you have this file on your instalation? Does this file have all the needed properties? You can check some examples in: - https://github.com/uyuni-project/uyuni/blob/master/backend/rhn-conf/rhn.conf - https://github.com/uyuni-project/uyuni/blob/master/java/buildconf/test/rhn.c...

Thank you Ricardo, I indeed forgot to re-run mgr-setup. But the file is actually there and filled out. I also made sure it is readable by everyone. Here the configuration: https://pastebin.com/vfdrrCkC (I also tried setting db_ssl_enabled = 0). Just now, I also noticed this line in the main catalina log seconds before (and not after) the stack trace. Is this directly impacting the error? 16-Dec-2020 10:25:50.873 WARNING [main] org.apache.catalina.startup.HostConfig.deployDescriptor The path attribute with value [/rhn] in deployment descriptor [/etc/tomcat/Catalina/localhost/rhn.xml] has been ignored Full trace of catalina.2020-12-16.log: https://pastebin.com/jSpX0pNc Full trace of localhost.2020-12-16.log: https://pastebin.com/Qd7mgWqT (unchanged as far as I can tell) How did you pinpoint the property "db_user"? If you guide me, I might be able to understand more of those stack traces. At the moment, I only understand the plain text and NPE :).

Hey Stefan, Regarding NPE yo can analyze stack trace, and check the code base in reverse order, starting from one class that is part of package *.rhn.* Java codebase is placed on https://github.com/uyuni-project/uyuni/tree/master/java/code/src For example:
at com.redhat.rhn.webapp.RhnServletListener.contextInitialized(RhnServletListener.java:125)
https://github.com/uyuni-project/uyuni/blob/master/java/code/src/com/redhat/...
at com.redhat.rhn.webapp.RhnServletListener.startHibernate(RhnServletListener.java:103)
https://github.com/uyuni-project/uyuni/blob/master/java/code/src/com/redhat/...
at com.redhat.rhn.common.hibernate.HibernateFactory.createSessionFactory(HibernateFactory.java:108)
https://github.com/uyuni-project/uyuni/blob/master/java/code/src/com/redhat/...
at com.redhat.rhn.common.hibernate.ConnectionManager.initialize(ConnectionManager.java:136)
https://github.com/uyuni-project/uyuni/blob/master/java/code/src/com/redhat/...
at com.redhat.rhn.common.hibernate.ConnectionManager.createSessionFactory(ConnectionManager.java:168)
https://github.com/uyuni-project/uyuni/blob/master/java/code/src/com/redhat/... First argument in the map is a static string, so the problem is that secound argument is returning null, and that is the configuration value for the database user name. I will try to investigate a bit more about the problem latter. Cheers, Ricardo On 12/16/20 9:52 AM, Stefan Bluhm wrote:
Thank you Ricardo,
I indeed forgot to re-run mgr-setup. But the file is actually there and filled out. I also made sure it is readable by everyone. Here the configuration: https://pastebin.com/vfdrrCkC (I also tried setting db_ssl_enabled = 0).
Just now, I also noticed this line in the main catalina log seconds before (and not after) the stack trace. Is this directly impacting the error? 16-Dec-2020 10:25:50.873 WARNING [main] org.apache.catalina.startup.HostConfig.deployDescriptor The path attribute with value [/rhn] in deployment descriptor [/etc/tomcat/Catalina/localhost/rhn.xml] has been ignored Full trace of catalina.2020-12-16.log: https://pastebin.com/jSpX0pNc Full trace of localhost.2020-12-16.log: https://pastebin.com/Qd7mgWqT (unchanged as far as I can tell)
How did you pinpoint the property "db_user"? If you guide me, I might be able to understand more of those stack traces. At the moment, I only understand the plain text and NPE :).
Thanks and best wishes,
Stefan

Hello Stefan,
This error is happening because the configuration property for `db_user` is not set on the rhn.config. I was able to reproduce the same error by commenting this property in my local server.
Default location for this file is `/etc/rhn/rhn.conf`. Do you have this file on your instalation? Does this file have all the needed properties?
You can check some examples in: - https://github.com/uyuni-project/uyuni/blob/master/backend/rhn-conf/rhn.conf - https://github.com/uyuni-project/uyuni/blob/master/java/buildconf/test/rhn.c...
Cheers, Ricardo

Hello Java Experts,
I am back at trying to get "rhn" to start on Tomcat/CentOS 8. Brief history:
OpenSUSE Leap 15.2 comes with a non-standard Java 11 OpenJDK version that integrates com.sun.xml.bind and allows usage by starting Java with the flag "--add-modules java.annotation,com.sun.xml.bind". As CentOS does not have these modules, the following packages need to be added: glassfish-jaxb-api, glassfish-jaxb-core, jaf, istack-commons-runtime. Using the same jars on Leap allows the removal of the module flag and the system starts up without any issues (that I noticed).
CentOS also does not show any "class not found" exceptions anymore so it sounds from that perspective, I am good.
Unfortunately, now the stack trace below is thrown. I guess this might have something to do with bundle/class version requirements. Can you please give me some suggestions how to best approach the issue resolutions? I am currently testing on a Uyuni installation itself, trying to get it to start.
Also any ad-hoc ideas where to focus the issue identification on the stack trace?
Thank you and best wishes,
Stefan
