ODI 11g - Scripting the Model and Topology

Scripting is the ideal mechanism to automate start up and teardown for repeated tasks and those that you just want to automate. Here are a couple of more illustrations of how to easily construct a model in ODI, the script will also create all of the topology objects. The script uses two methods; createLogicalSchema and createModel. The createLogicalSchema creates the logical schema, data server, physical schema and logical schema to physical schema mapping via a context all from one function call.

The signature of these methods looks like this;

createLogicalSchema

contextCode – the ODI code for the context used to map the logical schema to the physical

technologyCode – the ODI code for the technology

nameForLogicalSchema – the name for the logical schema to create

NameForDataserver – the name for the data server to create

userNameForAuthentication – the username for the connection to the data server

passwordForAuthentication – the password for the connection to the data server

urlForAuthentication – the URL for the connection to the data server

driverForAuthentication – the JDBC driver for the connection to the data server

schemaForAuthentication – the schema to use for the ODI physical schema

createModel

logicalSchemaObject – the ODI logical schema object (instance of ODILogicalSchema)

contextCode – the ODI context code for reverse engineering

nameForModel – the name for the model to create

codeForModel – the code for the model to create

So with these two methods or variations of them you can easily construct your topology objects and models. For example the call below creates a new model named ORACLE_MODEL and all of the topology objects that will allow me to go straight to reverse engineering when the script has been run.

lschema = createLogicalSchema("GLOBAL", "ORACLE", "ORACLE_EBS", "ORACLE_HQLINUX_DEV", "SCOTT",

    ObfuscatedString.obfuscate("<password>"), "jdbc:oracle:thin:@localhost:1521:orcl", "oracle.jdbc.OracleDriver", "SCOTT")

createModel(lschema, "GLOBAL", "ORACLE_MODEL", "ORACLE_MODEL")

Here is the source code for the script

def createLogicalSchema(contextCode, techCode, schName, dataserverName, userName, password, url, driver, schema) {
  txnDef = new DefaultTransactionDefinition();
  tm = odiInstance.getTransactionManager()
  txnStatus = tm.getTransaction(txnDef)

  contextFinder = (IOdiContextFinder) odiInstance.getTransactionalEntityManager().getFinder(OdiContext.class);
  context = contextFinder.findByCode(contextCode);

  techFinder = (IOdiTechnologyFinder) odiInstance.getTransactionalEntityManager().getFinder(OdiTechnology.class);
  tech = techFinder.findByCode(techCode);

  lschema = new OdiLogicalSchema(tech, schName)
  dserver = new OdiDataServer(tech, dataserverName)
  con = new AbstractOdiDataServer.JdbcSettings(url, driver)
  dserver.setConnectionSettings(con)
  dserver.setUsername(userName)
  dserver.setPassword(password)
  pschema = new OdiPhysicalSchema(dserver)
  pschema.setSchemaName(schema)
  pschema.setWorkSchemaName(schema)
  cschema = new OdiContextualSchemaMapping(context, lschema, pschema)

  odiInstance.getTransactionalEntityManager().persist(lschema)
  odiInstance.getTransactionalEntityManager().persist(dserver)
  tm.commit(txnStatus)
  return lschema
}

def createModel(lschema, contextCode, modName, modCode) {
  txnDef = new DefaultTransactionDefinition();
  tm = odiInstance.getTransactionManager()
  txnStatus = tm.getTransaction(txnDef)

  contextFinder = (IOdiContextFinder) odiInstance.getTransactionalEntityManager().getFinder(OdiContext.class);
  context = contextFinder.findByCode(contextCode);

  mod = new OdiModel(lschema, modName, modCode)
  mod.setReverseContext(context)
  odiInstance.getTransactionalEntityManager().persist(mod)
  tm.commit(txnStatus)
  return mod
}

lschema = createLogicalSchema("GLOBAL", "ORACLE", "ORACLE_EBS", "ORACLE_HQLINUX_DEV", "SCOTT", ObfuscatedString.obfuscate("<password>"),
"jdbc:oracle:thin:@localhost:1521:orcl", "oracle.jdbc.OracleDriver", "SCOTT")

createModel(lschema, "GLOBAL", "ORACLE_MODEL", "ORACLE_MODEL")

Have fun scripting!
