Sqlnet.ora
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[edit]
The sqlnet.ora file typically resides in $ORACLE_HOME/network/admin on UNIX platforms and %ORACLE_HOME%\NETWORK\ADMIN on Windows operating systems.[1]
Sample file[edit]

Profile parameters[edit]
This section lists and describes some sqlnet.ora file parameters.[2]
| Parameter | Purpose | Default | Values | Example |
|---|---|---|---|---|
| BEQUEATH_DETACH | Turning signal handling on or off (UNIX systems only). | No | Yes/No | BEQUEATH_DETACH=no |
| DEFAULT_SDU_SIZE | Defining the session data unit size. | 2048 bytes | 512 to 2 Mbytes Ora12c | DEFAULT_SDU_SIZE=512 |
| LOG_DIRECTORY_CLIENT | Defining the destination directory for the client to write the logs. | Current directory from which the executable is started | path to the directory | LOG_DIRECTORY_CLIENT=/oracle/net/log |
| LOG_FILE_CLIENT | Defining client's log filename. | sqlnet.log | name of the file | LOG_FILE_CLIENT=client.log |
| LOG_FILE_SERVER | Defining the server's log filename. | sqlnet.log | name of the file | LOG_FILE_SERVER=server.log |
| SQLNET.CRYPTO_CHECKSUM_CLIENT | Client checksum behaviour defining. | accepted | accepted; rejected; requested; required | SQLNET.CRYPTO_CHECKSUM_CLIENT=rejected |
| SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT | Determine the crypto-checksum algorithms used by client. | all available algorithms | md5; sha1 | SQLNET.CRYPTO_CHECKSUM_TYPES_CLIENT=(SHA1) |
| SQLNET.CRYPTO_SEED | 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 $ORACLE_HOME/network/admin/sqlnet.ora. | qwertyuiopasdfghjkl;zxcvbnm,.s1 | 10-70 characters | SQLNET.CRYPTO_SEED="kbguhfplhc5c4626fy[67vg;yd" |
