Interview Questions.

Q1. How To Create First Internet Directory?

Creating the First Oracle Internet Directory Instancez:

When you put in Oracle Internet Directory on a number pc, Oracle Identity Management 11g Installer creates an Oracle Fusion Middleware machine component of Type=OID in a brand new or existing Oracle instance (ASINST). The Oracle Internet Directory thing consists of an OIDMON method and an Oracle Internet Directory instance (inst=1). The Oracle Internet Directory example consists of a dispatcher manner and one or greater OIDLDAPD methods. The issue name for the first Oracle Internet Directory factor is typically oid1 and the Oracle instance call is selected at some stage in the set up, usually asinst_1.

Oracle Identity Management 11g Installer creates the subsequent instance-particular configuration entry for this thing for the duration of set up:

cn=oid1,cn=oidldapd,cn=sub config subentry

In addition, Oracle Identity Management 11g Installer creates a few document system directories beneath the Oracle instance listing. Some of the pathnames it creates are are precise to the issue call.

For example, the pathnames below your Oracle example on UNIX or Linux encompass:

ORACLE_INSTANCE/config/OID/oid1

ORACLE_INSTANCE/diagnostics/logs/OID/oid1

If you chose Create New Domain or Extend Existing Domain for the duration of installation, the Oracle Internet Directory component is registered with a WebLogic area. If you selected Configure Without a Domain in the course of installation, the Oracle Internet Directory aspect is not registered with a website. You can check in it later from the command line. Registering with a website in this case is non-compulsory.

Q2. Need Of Oracle Internet Directory ?

Use of Oracle Internet Directory (Oracle’s LDAP) is an awful lot bigger and may’t be defined on this submit however right here is few bits that you is enough for time being (to get you commenced on OID).

OID is repository for agency users, companies facts.

Information approximately diverse programs (Portal, BI, E-Business Suite, Collaboration Suite) registered to OID (You can register E-Business Suite or Database in OID).

Password coverage for Single Sign-On Partner Applications

Q3. How To Delete Oid ?

$ ldapdelete -h my-host-name -p 389 -D “cn=orcladmin” -w mypassword “cn=TESTENTRY,cn=OracleContext,dc=mycompany,dc=com”

Q4. What Are Different Daemon/server In Oid ?

There are three servers/daemon in OID:

OIDLDAPD – This is the principle server/daemon looking forward to ldap request (ldapsearch, ldapadd, ldapmodify, ldapdelete..). When any software need to do any ldap operation(add, alter, delete, seek..) on OID item (person, group, application..), that request is fulfilled by this server/daemon.

ODISRV – additionally known as as Oracle Directory Integration Server, this is used for integration of Various Application (Portal, BI, E-Business Suite/Apps) with OID for user/organization facts. If any person/group is added/deleted in Portal/BI synchronization of that consumer to OID is done by using this Daemon (Vice Versa). If you have got Integrated Apps(11i/R12) with OID/SSO then customers is provisioned/de-provisioned the usage of this daemon of OID.

OIDREPLD – Also referred to as as OID Replication Daemon is used when you have replicated OID. By default this daemon is disabled.

Q5. What Is Ldap ?

LDAP stands for Lightweight Directory Access Protocol. In undeniable and easy terms, its a database wherein it has all of the information of all of businesses, people, and other sources inclusive of documents and gadgets in a community, whether or not on the Internet or on company intranetand whether or not you understand the domain call, IP deal with, or geographic whereabouts. An LDAP directory may be disbursed amongst many servers on a community, then replicated and synchronized frequently. An LDAP server is also called a Directory System Agent (DSA). Itsa no longer a relational database. Outlook and different e mail applications makes use of LDAP to look for a recipient in an organisation.

Q6. How To Registering An Oracle Instance Or Component With The Weblogic Server?

If you want to manage an Oracle Internet Directory aspect with Oracle Enterprise Manager Fusion Middleware Control, you need to sign up the aspect and the Oracle instance that contains it with a WebLogic domain. You can sign in an Oracle instance with a WebLogic domain all through set up or Oracle example introduction, however you aren't required to achieve this. If an Oracle instance was no longer previously registered with a WebLogic domain, you can register it by means of using opmnctlregisterinstance.

Q7. How To Creating An Oracle Internet Directory Component By Using Opmnctl?

WE create an Oracle Internet Directory gadget thing in an Oracle instance via the usage of opmnctlcreatecomponent. This command robotically registers the thing with a WebLogic area on the time you create the element, as long as the example is in a registered nation.

Q8. What Is The Relationship Between Ldap And Jndi?

JNDI has lessons supplied by way of SUN so one can assist ur appln engage with and LDAP server. JNDI appln work further to JDBC appln once and be unfastened to use ‘drivers’ from exceptional providers. SUN gives the “driving force” as a way to assist interact with the LDAP server. Sun additionally provides “drivers” for different naming services (like CORBA).

Q9. How To Modify Oid Entities?

$ ldapmodify -h my-host-name -p 389 -D cn=orcladmin -w mypassword -c -v -f <filename>.Ldif

Q10. How To Start/prevent Oid ?

OID Data such as repute of OID Servers (OIDLAPD, ODISRV OIDREPLD) is saved in Oracle Database so which will begin OID first start Database and Database Listener. Then

To Start OID – opmnctl startproc ias-thing=OID

To Stop OID – opmnctl stopproc ias-component=OID

OPMNCTL will first start OIDMON (OID Monitoring Process) after which teach OIDCTL (OID Control) to begin OIDLDAPD and ODISRV daemons.

Q11. How To Start & Stop Oid?

To begin OID:

$ORACLE_HOME/opmn/bin/opmnctlstartall

To stop:

$ORACLE_HOME/opmn/bin/opmnctlstopall

Q12. How Can I Join Information Contained In Different Directories?

Distributed, Multivendor directories glued collectively with the aid of referrals and references.

Q13. How To Add Oid Entities?

$ ldapadd -h my-host-name -p 389 -D “cn=orcladmin” -w mypassword -f names.Ldif

Q14. What Is Slapd?

SLAPD stands for Stand-Alone LDAP.Clients connect with the server over the LDAP protocol, commonly using a network-primarily based connection (though SLAPD gives a UNIX socket listener).

Q15. Is There Graphical Editors For Ldap ?

Yes, Following are a few GUI primarily based tools for LDAP

GQ

Java LDAP Browser/Editor

Softerra LDAP Browser

Q16. What Is Oracle Internet Directory(oid)?

An online directory is a specialized database that stores and retrieves collections of facts about items. The information can represent any assets that require management.

For example:

Employee names, titles, and security credentials

Information approximately companions

Information about shared sources inclusive of convention rooms and printers.

The statistics inside the directory is available to distinct clients, consisting of unmarried sign-on answers, electronic mail customers, and database applications. Oracle Internet Directory is an LDAP directory that uses an Oracle Database for storage. Clients talk with a listing server by way of me of the Lightweight Directory Access Protocol (LDAP).

Q17. How To Lookup Oid Entities?

Ldapsearch -h my-host-name -p 389 -D “cn=orcladmin” -w mypassword -b “cn=TESTENTRY,cn=OracleContext,dc=mycompany,dc=com” -s base “objectclass=*” orclnetdescstring

Q18. Where To Find Log Files Related To Oid?

Logs associated with OIDMON, OIDCTL, OIDLDAPD have to be in $ORACLE_HOME/ldap/log directory , ODISRV related logs have to be in $ORACLE_HOME/ldap/ODI/log.

Q19. Why Ldap Is Called Light Weight?

LDAP (Lightweight Directory Access Protocol) is a protocol for communications between LDAP servers and LDAP customers.

LDAP servers save “directories” which might be get right of entry to with the aid of LDAP customers.

LDAP is called lightweight because it's miles a smaller and easier protocol which was derived from the X.500 DAP

(Directory Access Protocol) defined in the OSI community protocol stack.
