Moqui 1.4.1 Postgresql Configuration

Question

I am trying to get the Moqui 1.4.1 release up and running but using Postgres as the database platform. Here are the platform details.

• <\/li>
• <\/li><\/ul>

  Firstly, I can't find MoquiDefaultConf.xml anywhere so I assume this is only applicable to development?

  In all four, I have added the following entity-facade entry.

   
        
   
         
  <\/li>
   
         
  <\/li><\/ol>
   Then the process gets stuck.<\/strong>
   As you've pointed out, this only has the pre-built WAR file in it. However, if I browse the contents of the WAR file, I find no MoquiDefaultConf.xml file. In fact, the only XML file in the whole WAR file is web.xml.
   I then copied the datasource element out of that and simply pasted that into the entity-facade of ALL the listed Moqui*Conf.xml to make sure it got picked up....which it finally did but with the halting issue. I tried both inline jdbc options; once with the one with the xa-properties tag and once with the one without.
   I am from a Microsoft background so this is all a bit foreign to me , but in my defence I was technically capable of getting OFBiz up and running by fumbling around like this.
   Progress.
   Not sure if that was contributing to the halting but I upgraded to Postgres 9.4 with postgresql-9.3-1102.jdbc41.jar driver, and the halting was still happening.
   The reason this happened was because I had initially tried to cobble the datasource element together from OFBiz equivalent, and when I eventually found the MoquiDefaultConf.xml online, I only copied the inline-jdbc elements into the datasource elements I used from OFBiz and didn't copy the whole datasource element. Silly. Anyway, after adding the datasource element to ONLY the MoquiDevConf.xml and "gradle load"ing, 91 tables were created in Postgres so the build completed successfully....well sort of.
   I can confirm that the webapp is talking to Postgres because I created an entry in the Example grid and it appeared in the example table in Postgres. I don't know enough about the internals to know if queries are duplicating on the derby database.
   Ie when I put the datasource in only the MoquiProductionConf.xml entity-facade element, it has no effect and creates tables only in derby (well...over 100 .dat files) and none in Postgres. This is confusing given that MoquiInit.properties only ever references MoquiProductionConf.xml. I can confirm that building using MoquiDevConfig.xml generates about 20 fewer .dat files than does MoquiProductionConf.xml. I don't know enough about Gradle build files to know what to change.
   
        

Answer 1

The MoquiDefaultConf.xml file is in the pre-built executable war file if you downloaded the binary release, though you can see it here in the source repo:

https://github.com/moqui/moqui/blob/master/framework/src/main/resources/MoquiDefaultConf.xml

In there you will see an example configuration for Postgres:

    <datasource group-name="transactional" database-conf-name="postgres" schema-name="public" startup-add-missing="true" runtime-add-missing="false">
        <inline-jdbc pool-minsize="5" pool-maxsize="50">
            <xa-properties user="moqui" password="moqui" serverName="localhost" portNumber="5432"
                           databaseName="MoquiDEFAULT"/>
        </inline-jdbc>
        <!-- <inline-jdbc jdbc-uri="jdbc:postgresql://127.0.0.1/MoquiDEFAULT"
                jdbc-username="moqui" jdbc-password="moqui" pool-minsize="2" pool-maxsize="50"/> -->
    </datasource>

Note especially these two attributes on the datasource element: startup-add-missing="true" runtime-add-missing="false". Postgres does not support creating tables on the fly, so they all have to be created before the system gets running instead of the default mode which is to create tables only as they are needed (when the first write is done).

The MoquiDefaultConf.xml file also has a definition for the "tenantcommon" entity group, pointing it to Derby:

    <datasource group-name="tenantcommon" database-conf-name="derby" schema-name="MOQUI">
        <inline-jdbc pool-minsize="2" pool-maxsize="10">
            <xa-properties databaseName="${moqui.runtime}/db/derby/MoquiDEFAULT" createDatabase="create"/>
        </inline-jdbc>
    </datasource>

To put those entities in Postgres as well you'll need to add a similar definition to the Moqui Conf XML file used at runtime.

Answer 2

Use this config inside entity-facade tag in MoquiDevConf.xml or MoquiProductionConf.xml

<datasource group-name="transactional" database-conf-name="postgres" schema-name="public" startup-add-missing="true" runtime-add-missing="false">
        <inline-jdbc jdbc-uri="jdbc:postgresql://localhost/dbname" jdbc-username="postgres" jdbc-password="pass"/>
</datasource>
