Configure sqlnet.ora
* Located in $ORACLE_HOME/network/admin directory.
* Default directory can be overriden with TNS_ADMIN environment variable. Useful if multiple Oracle homes are present.
Choose naming methods
# Use Oracle naming only NAMES.DIRECTORY_PATH= (ONAMES) # Default, use tnsnames.ora file first, then Oracle names, use host naming last NAMES.DIRECTORY_PATH= (TNSNAMES, ONAMES, HOSTNAME)
Choose default domain.
– Default domain is appended to a service name if it does not contain a dot character.
# Default domain is world NAMES.DEFAULT_DOMAIN = world # Set default domain to my.com NAMES.DEFAULT_DOMAIN = my.com
Choose trace file location
– Defaults to $ORACLE_HOME/network/trace/sqlnet.trc
# Output trace file to /home/oracle/trace/net8.trc TRACE_DIRECTORY_CLIENT = /home/oracle/trace TRACE_FILE_CLIENT = net8.trc
Choose log file location
– Defaults to $ORACLE_HOME/network/log/sqlnet.log
LOG_DIRECTORY_CLIENT = $ORACLE_HOME/network/log LOG_FILE_CLIENT = net8client.log
Configure tnsnames.ora
* Located in $ORACLE_HOME/network/admin directory.
* Default directory can be overriden with TNS_ADMIN environment variable. Useful if multiple Oracle homes are present.
* Syntax
net_service_name =
(DESCRIPTION =
(ADDRESS = (address_data))
(CONNECT_DATA =
(SERVICE_NAME = database_service_name)
(INSTANCE_NAME = sid)
)
)Address_data syntax
* TCP/IP
(PROTOCOL = TCP)(HOST = hostname | ip_address)(PORT = port_num)
# Example
orcl =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = db.my.com)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)* Bequeath
– Client and Server on same machine
– No need for Net8 listener
– dedicated server connection only
(PROTOCOL = BEQ)(PROGRAM = oracle_exe)(ARGV0 = sid_identifier) (ARGS = '(DESCRIPTION=(LOCAL = YES)(ADDRESS = (PROTOCOL = BEQ)))') # oracle_exe: oracle # sid_identifier: concatenation of oracle_exe and SID, e.g. oracleORCL
* IPC
– Client and server on same machine
– Still need Net8 listener up and running (bequeath does not need)
(PROTOCOL = IPC)(KEY = key_name) # key_name MUST match listener key_name defined in listener.ora
* SPX
– Novell protocol
(PROTOCOL = SPX)(SERVICE = spx_service_name) # key_name MUST match listener key_name defined in listener.ora
* named pipes connections
– Allows IPC across a Microsoft network
– Need to install Client for Microsoft Networks
(PROTOCOL = NMP)(SERVER = server_name)(PIPE = pipe_name)
Config LDAP
Create an ldap.ora file to contain
* LDAP host and port number
DIRECTORY_SERVERS = (ldap1.my.com:389:636, ldap2.my.com:389:636) # port 389 for non-SSL # port 636 for SSL
* Default admin context
DEFAULT_ADMIN_CONTEXT ="dc=my, dc=com"
* LDAP server type/brand
DIRECTORY_SERVER_TYPE = [OID | AD |NDS]
