How to backup Oracle Internet Directory (OID) 11g – Data : Full / Partial
Oracle Internet Directory (OID) is LDAP Server from Oracle that stores LDAP data (user’s, groups, permission etc) in Oracle Database (under ODS schema).
OID consists of two parts
- LDAP Data: stored in ODS schema in Oracle database
- LDAP binaries , executable and logs : stored in OID ORACLE_HOME (different from database ORACLE_HOME) and ORACLE_INSTANCE (OID 11g)
OID Backup
- For full OID backup :
a) Backup OID database using database backup technology.
b) Backup file system OID ORACLE_HOME and ORACLE_INSTANCE in 11g OID
- For partial OID backup (i.e. cn=Users or cn=Groups container and all entries under that container) in LDIF fileldifwrite connect=”[database_connect_string]” basedn=”[DN_of_entry_to_backup]” ldiffile=”backupfile.ldif”where [database_connect_string] is TNSNAME entry defined in ORACLE_INSTANCE/config/tnsnames.oraExample to backup cn=Users and all the entries under thisldifwrite connect=”OIDDB” basedn=”cn=Users,dc=mydomain,dc=co,dc=uk” ldiffile=”backupfile.ldif”
Things good to know:
- There is ldifwrite in Unix/Linux O.S. , use ldifwrite from $ORACLE_HOME/ldap/bin
- ldifwrite command will prompt for OID password. Enter ODS schema password here (This is different from cn=orcladmin password)
