hi,

are you sure, all ACT_xyz tables have been setup properly in your database ?
Check your process engine configuration and make sure, "databaseSchemaUpdate" has been set to a valid value.

db - empty (((

Check your process engine configuration and make sure, "databaseSchemaUpdate" has been set to a valid value.

activiti-standalone-context.xml

<property name="databaseSchemaUpdate" value="true" />

Hi,

If I look at the exception it touches the following code:

806 if (isEngineTablePresent()) {
807      // the next piece assumes both DB version and library versions are formatted 5.x
808      PropertyEntity dbVersionProperty = selectById(PropertyEntity.class, "schema.version");
809      dbVersion = dbVersionProperty.getValue();

In your stacktrace line 808 is mentioned, which checks the schema version.
This also means that the ACT_RU_EXECUTION table is present because that's what line 806 checks.
Does the user you use have rights to create tables and are you looking at the correct schema?

Best regards,

Does the user you use have rights to create tables

YES!

are you looking at the correct schema

what that you mean
SchemaName = LoginName

Re: activiti + oracle db

trademak — Fri, 14 Dec 2012 08:31:14 GMT

what that you mean
SchemaName = LoginName

YES!

When I look at your stack trace, the database should have a ACT_RU_EXECUTION table, otherwise it wouldn't reach that line in the code.

Best regards,

Best regards,

schemaName= loginName
why don't make the table
PS: is second schemaName for activiti in this DB

finded, solution
_https://jira.codehaus.org/browse/ACT-1404

just added
<property name="databaseSchema" value="${db.username}" />

Re: activiti + oracle db

mouserok — Thu, 07 Feb 2013 09:14:30 GMT

But, after restart activiti I get error
java.sql.SQLException: ORA-00955: name is already used by an existing object
if delete
<property name="databaseSchema" value="${db.username}" />then restart - work fine

but, there is no univerchalnost
first start need add <property name="databaseSchema" value="${db.username}" />why, don't work after restart ???

Re: activiti + oracle db

jbarrez — Thu, 07 Feb 2013 10:08:25 GMT

why, don't work after restart ???

Could you provide the stacktrace you see? That way we can identify where in the process it goes wrong.

Re: activiti + oracle db

mouserok — Thu, 07 Feb 2013 11:57:57 GMT

START OPTION
- schema - activiti_test
- in "activiti-standalone-context.xml"
added
<property name="databaseSchema" value="activiti_test" />

1. First start tomcat
tables in schema - 0
at the first start activiti create - 22 tables

ACTIVITI - WORK fine

2. Second start
tables in schema - 22

ACTIVITI - doesn't work

INFO: performing create on engine with resource org/activiti/db/create/activiti.oracle.create.engine.sql

For some reason the engine decides you haven't got the tables yet.
How does you whole activiti.cfg.xml look like? Did you set the schema create on true?

The code does take in account the schema:


 String schema = this.connectionMetadataDefaultSchema;
      if (dbSqlSessionFactory.getDatabaseSchema()!=null) {
        schema = dbSqlSessionFactory.getDatabaseSchema();
      }
      
      String databaseType = dbSqlSessionFactory.getDatabaseType();
      log.debug("Looking for table " + tableName + " for database type " + databaseType);
      if ("postgres".equals(databaseType)) {
        tableName = tableName.toLowerCase();
      }
      
      try {
        tables = databaseMetaData.getTables(this.connectionMetadataDefaultCatalog, schema, tableName, JDBC_METADATA_TABLE_TYPES);
        return tables.next();
      } finally {
        tables.close();
      }

But that doesn't seem to do the trick for you it seems.

Re: activiti + oracle db

No, i didn't test it, i just posted relevant code snippets which should prove it works as advertised.

For some reason the engine thinks the tables don't exist yet…. Could you create a jira issue so I can track it officially?

Re: activiti + oracle db

grantgochnauer1 — Fri, 15 Feb 2013 13:51:59 GMT

Hi –

I ran into this yesterday. Make sure your username that you are connecting with is in all upper case because Oracle is case sensitive.

So switching the connection from a username of "myuser" to "MYUSER" fixed the issue with the fact that Activiti couldn't see the tables it created and thus would try to recreate them over and over.

Best,
Grant
