tea.products

tea.products is a dictionary with a collection of (name,value) pairs. The tea.products command is used to list the products registered with the server that support Python binding. The following is an example of the product list generated by the command:

>>> tea.products
{'TIBCOSecurityServer': <'TIBCOSecurityServer','
:TIBCOSecurityServerAgent:1.0:TIBCOSecurityServer:
TIBCOSecurityServer'>, 'EMS
': <'EMS',':EMSAgent:1.0:EMS:EMS'>}
>>>

The output shows EMS as the product registered. The command help(tea.products['EMS']) lists the functions supported by the Tomcat product.

>>> help(tea.products['EMS'])

>>>

tea.products.keys()

You can use tea.products.keys() to get a list of names of the products registered with the server.

>>> tea.products.keys()
dict_keys(['TIBCOSecurityServer', 'EMS'])

tea._products_with_provisional_apis

tea._products_with_provisional_apis is used to list the products registered with the server that have provisional apis. By default, the APIs exposed by the TIBCO Enterprise Administrator server do not support Python binding.

tea. product_with_provisional_api(name)

You can check whether or not a product has provisional apis by using the function, tea.product_with_provisional_api(name). Pass the product name as the parameter to the function. On finding the product in the tea._products_with_provisional_apis dictionary, the function returns the object of the product type along with a message that the Python API for the product is provisional. It is not supported but that is likely to change in future. If the product name is found in tea.products dictionary, the function returns None along with a message indicating that it is available in tea.products dictionary. If not, it prints the warning message that the product with the specified name does not exist.

To support multiple retry attempts, this method also takes retry and wait as parameters as shown in the following code snippet:

tea. product_with_provisional_api(name, retry, wait) where,
name: is the name of the product you are looking for
retry: is the number of retry attempts
wait: is the interval to wait between two retry attempts.

if retry > 1, the system searches for the product in provisional products dictionary till the number of retry attempts exhaust. If it finds the product, it returns the product and stops further retry attempts. If the product is not found after the specified retry attempts, an exception with a message is raised.

tea. products_with_provisional_apis()

tea. products_with_provisional_apis() returns a list of names of the products having provisional API, along with a warning message that the Python API for these products are provisional. They are not supported and are likely to change in future.

tea.product()

The tea.product() method is invoked on the EnterpriseAdministrator object, which is tea in this example. The method returns the supported products from the Python dictionary. Takes the three parameters as shown in the code snippet:

tea.product(name, retry, wait) where,
name: is the name of the product you are looking for
retry: is the number of retry attempts
wait: is the interval to wait between two retry attempts.

if retry > 1, the system searches for the product in products dictionary till the number of retry attempts exhaust. If it finds the product, it returns the product and stops further retry attempts. If the product is not found after the specified retry attempts, an exception with a message is raised.

if the retry parameter is not specified, the product() method returns the specified product from the products dictionary if it is available in it. If it is not available in the products dictionary, but it is available in the provisional products dict, None is returned with a proper WARNING message. If it is not available in any dictionary, it returns None and prints a WARNING message.

<Product>.module_ or <Member>.module_

You can use module_ on a product or a member to get the modules of Plain Old Java Object (POJO) objects available on the product or member. module_ is attached to each top level or member object. For example, the following is an example of using module_ on a member:

tea._products_with_provisional_apis['Tomcat'].
members['Server 1'].module_

For products, we can use tea._products_with_provisional_apis['Tomcat'].module_ to retrieve the modules of POJOs on Tomcat. After obtaining the modules of POJO, you can pass a POJO as a parameter to a function in a Python script. For example:

# get an instance of the product as follows -
>>>prod = tea._products_with_provisional_apis['Tomcat']

# Module of POJOs is available on that product or member
 in variable "module_"
>>> mod = prod.module_
 
# Instantiate the POJO class in python as follows
>>> person = mod.Person("John Doe", 1)
 
# Invoke the TeaOperation with the python object in the earlier line
 as TeaParam and consume the POJO response as a Python Object
>>> response = prod.hw(person)

When you get an POJO as a return type, you can use the POJO like a regular Python object.

# Use the response as you use the regular python object
>>> response.name
'John Doe'
>>> response.i
1

tea.agents

You can use tea.agents to access the agents registered with the server. For example, tea.agents.agents.registerAgent(name,url,description) helps you register an agent with the server.

tea.users

You can use tea.users to create users, assign roles, groups to users. For example, you can create users using the tea.users.createUser(self, name, password, groups, roles) command.

tea.machines

You can use tea.machines to get more information about the machines on which the agents are running.

1. After registering the first agent, the products list gets refreshed automatically, but after registering the second agent, the products list does not refresh. Remember to explicitly refresh the products list of the second agent.
2. After unregistering the agent, the agents dictionary must be refreshed explicitly.
3. Recently updated agents, solutions, products, and dictionaries should be explicitly refreshed before accessing their members, keys, items, and other details.
