In database computing, sqlnet.ora is a plain-text configuration file that contains the information (like tracing options, encryption, route of connections, external naming parameters etc.) on how both Oracle server and Oracle client have to use Oracle Net (formerly Net8 or SQL*Net) capabilities for networked database access.
Location The sqlnet.ora file typically resides in on UNIX platforms and on Windows operating systems.
Sample file
NAMES.DIRECTORY_PATH= (LDAP, TNSNAMES, HOSTNAME) NAMES.DEFAULT_DOMAIN = ORACLE.COM TRACE_LEVEL_CLIENT = ON SQLNET.EXPIRE_TIME = 30 SQLNET.IDENTIX_FINGERPRINT_DATABASE = FINGRDB AUTOMATIC_IPC = ON SQLNET.AUTHENTICATION_SERVICES = (ALL) SQLNET.CRYPTO_CHECKSUM_CLIENT = ACCEPTED TNSPING.TRACE_DIRECTORY = /oracle/traces
Profile parameters This section lists and describes some sqlnet.ora file parameters. Parameter Purpose Default Values Example Turning signal handling on or off (UNIX systems only). Defining the session data unit size. 2048 bytes 512 to 2 Mbytes Ora12c Defining the destination directory for the client to write the logs. Current directory from which the executable is started path to the directory Defining client's log filename. sqlnet.log name of the file Defining the server's log filename. sqlnet.log name of the file Client checksum behaviour defining. accepted accepted; rejected; requested; required Determine the crypto-checksum algorithms used by client. all available algorithms md5; sha1 Determine symbols to generate the cryptographic key. This parameter must not be set in CRS environments. CRS will fail to start if this value is set in CRS/Grid . 10-70 characters Determine list of cryptographic ciphers used by SSL to encrypt the traffic.
