38. What is a Repository and difference between repository database and repository service?

Ans: Repository is metadata which means it has data about the data (objects). It stores the data regarding the Informatica objects .For e.g.: We have a folder say “Folder1” and 3 mappings has been created within it, so all the information regarding all objects in mapping and the folder will be stored in repository database in forms of tables.

Repository database is a database which contains all the metadata whereas the repository service is nothing but a service which runs on repository database and provides its services.
OPB_Mapping: This table contains all the mapping names.

39. What is a code page?

Ans: Code page contains encoding to specify characters in a set of one or more languages.
e.g.: If you have Malaysian or Chinese character in your source data then you have to choose the appropriate code page for these characters else you’ll see square boxes once the data is loaded and processed as Informatica will not be able to understand those characters.

40. Pmrep and pmcmd command?

Ans: pmrep and pmcmd commands are the command line interface to perform Informatica related task. These command s are used most in form of scripts. Pmrep is used for all repository related tasks. Pmcmd is used for Informatica monitor and server related tasks

Eg: pmrep connect –r Repository_name –d Domain_name –n Username –x password
the above command connects to repository. Once connected you can create a folder in repository by below command

Pmrep createfolder –f Foldername –o OwnerName

Some of the pmcmd commands:
I. Startworkflow
II. Stopworkflow
III. Waitworkflow
IV. Recoverworkflow
V. Scheduleworkflow
VI. Startask
VII. Stoptask

41.   How to start a workflow using pmcmd command?

Ans: 
Pmcmd startworkflow [ folder]
[ taskInstancePath []]
[ paramfile]
[ localparamfile]
[ OSProfile] [-wait|-nowait]
[ runInsName] workflow


42. What is deployment group?

Ans: A deployment group is a global object that consists of versioned objects from one or more folders. You use a deployment group to copy the versioned objects to another folder or repository. You can use a deployment group when you want to copy some, but not all, of the objects in a folder. You can also use a deployment group to copy objects from multiple folders.

43. How would you join a node to the already existing domain?

Ans: Joining a node to an existing domain can be archived while installing Informatica.
e.g.: Server is on machine1 and the new node is on machine2. Then go to machine2-Open Installer->join node to domain while configuring domain and provide the existing domain details.

44. What is primary and backup node?

Ans: Primary node is a node where a current node or applications are running and backup node is defined to run the domain or application

45. Is it possible to create multiple domains on a single Informatica server?

Ans: Yes it is possible to create multiple nodes on same Informatica server.

46. What is a grid in Informatica?

Ans: Grid in Informatica is used for load balancing. A grid is nothing but a combination of nodes which distributes the request among them.

Eg: node1, node2, node3, node4 are assigned in a grid. 10 workflows started simultaneously. Now instead of giving burden to a single node to run the 10 workflows the request for running workflows will be distributed to all nodes.

47. Can we create Integration service without a Repository service and vice versa?

Ans: It is not possible to create an Integration service without a repository service however a repository can be created without an integration service.

48. Can we create multiple integration service on single repository?

Ans: Yes it is possible to create multiple integration service on single repository. This is used when you have to choose different code page for different integration service in same repository

Eg: Repository: ASIA_PACIFIC_Repo is used to load the data for countries specific to ASIA PACIFIC to target warehouse.

49. What is native users?

Ans: Native users are the users created with admin console.

50. What is meant by LDAP users?

Ans: LDAP users are the user which are configured with LDAP server (also may be MS Active directory) and LDAP is integrated with power center to allow users to provide single sign on.

51. What are roles and groups and benefits of using them?

Ans: Domain is a single point of entry or the administrative unit in Informatica. All the request from different clients (like Designer) first reaches to domain and then routed to associated services. A gateway node is the node on which a domain is defined.

52. What is resilience time?

 Ans: Resilience time is the time defined in Informatica to wait before it lose the connection
on a network failure.

E.g.: If your resilience time is 180 sec and the network goes down so Informatica will wait for 180 sec and if network is established in between, the connection will be established. If the network is not up within 180 sec so the unsaved data will be lost and the client will be disconnected from the domain or repository

53. What are the services provided in informatica client tool?

    a)  Workflow Manager, Repository Manager, Workflow Monitor, Mapping Designer
    b)  Repository Designer, Mapping Monitor, Workflow Monitor, Workflow Manager
    c)  Both a and b

54. What is the service used to run sessions and workflows?

    a)            Integration service
    b)            Repository service
    c)            Repository manager
    d)            Domain service

Ans:       a

55. What is the service used to schedule workflows?

    a)            Workflow monitor
    b)            Workflow manager
    c)            Repository manager
    d)            Designer

Ans:       Workflow manager
