Install Oracle Internet Directory (OID) in Standalone mode


Oracle Internet Directory (OID) is an LDAP server which uses an Oracle database as a datastore. Client machines can use the OID for all TNS lookups. With OID. Once all client machines are configured correctly any modifications to the TNS lookups can be done from a central location reducing the amount of client machine administration.

This guide is about installing and using Oracle Internet Directory in Standalone mode, no need for Oracle Fusion Middleware Infrastructure.

Step-by-step guide

Download Oracle Internet Directory (Part of identity management) from
http://www.oracle.com/technetwork/middleware/id-mgmt/downloads/index.html

Install OID, follow instructions:
https://docs.oracle.com/en/middleware/lifecycle/12.2.1.3/inoim/installing-product-software.html#GUID-5D47117E-3983-4BED-BADB-CB7DDD63DB34

Starting the Installation Program:
./fmw_12.2.1.3.0_oid_linux64.bin
Configure the Domain:
$ORACLE_HOME/oracle_common/common/bin/config.sh
Start the Servers for Standalone Oracle Internet Directory:
DOMAIN_HOME/bin/startNodeManager.sh
Perform Initial Oracle Internet Directory Setup:
$ORACLE_HOME/oracle_common/common/bin/wlst.sh

nmConnect(username='wls_user',password='password',domainName='base_domain')

oid_setup(orcladminPassword='password',odsPassword='password',realmDN='dc=us,dc=oracle,dc=com')
Start the Repository Creation Utility:
$ORACLE_HOME/oracle_common/bin/rcu
fix permissions (Doc ID 947285.1):
vi ldifFile

dn: cn=oid1,cn=osdldapd,cn=subconfigsubentry
changetype: modify
replace: orclAnonymousBindsFlag
orclAnonymousBindsFlag: 1

ldapmodify -D cn=orcladmin -q -p 3060 -h oid -f ldifFile
Modify the file sqlnet.ora in $ORACLE_HOME/network/admin directory need to have the following line:
NAMES.DIRECTORY_PATH= (LDAP,TNSNAMES,EZCONNECT)
Create the file ldap.ora in the $ORACLE_HOME/network/admin directory location.
This file has information of the server where the LDAP directory resides along with the port numbers for normal and secure connections
DEFAULT_ADMIN_CONTEXT = "dc=us,dc=oracle,dc=com"
DIRECTORY_SERVERS = (oid.mydomain.local:3060:3131)
DIRECTORY_SERVER_TYPE = OID
NAMES.DEFAULT_DOMAIN = mydomain.local
Add tns entry in OID (TESTTNS will be the tns alias):
vi add_entry.ldif

dn: cn=TESTTNS,cn=OracleContext,dc=us,dc=oracle,dc=com
objectclass: top
objectclass: orclNetService
cn: TESTTNS
orclNetDescString: (DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=oid)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=oid)))
orclnetdescname=000:cn=DESCRIPTION_0
Load the ldif file:
ldapadd -h oid -p 3060 -c -D "cn=orcladmin" -f add_entry.ldif -w mypassword
We will now check a connection to the alias TESTTNS ensuring that the SQL*Net connection details are now obtained from the OID LDAP directory and not using information stored in the local tnsnames.ora file.

Note: the output of the tnsping command shows that the LDAP directory was accessed to resolve the alias

tnsping TESTTNS
