#TOAD FOR ORACLE 12.1 TIMEOUT UPDATE#
Only clients which have applied critical patch update CPUOct2012 or later, or release 11.2.0.3 clients with an equivalent update can connect to the server.Ĭlients using Oracle Database 10 g and later can connect to the server.Ĭlients using releases earlier than Oracle Database release 11.2.0.3 that have not applied critical patch update CPUOct2012 or later patches must use the 10G password version.

Only Oracle Database 12 c release 12.1.0.2 or later clients can connect to the server. Value of the ALLOWED_LOGON_VERSION_SERVER Parameter The following table describes the allowed values, password versions, and descriptions: Clients that are more recent have all the capabilities of the older clients. O3L: The ability to perform the Oracle8 i database authentication protocol using the 10G password version.Ī higher ability is more recent and secure than a lower ability. O4L: The ability to perform the Oracle9 i database authentication protocol using the 10G password version. O5L: The ability to perform the Oracle Database 10 g authentication protocol using the 10G password version. O5L_NP: The ability to perform the Oracle Database 10 g authentication protocol using the 11G password version, and generating a session key encrypted for critical patch update CPUOct2012.

O7L_MR: The ability to perform the Oracle Database 10 g authentication protocol using the 12C password version. Clients that are more recent have all the capabilities of the older clients, but older clients tend to have less abilities than more recent clients. The following is the list of all client abilities. If the client does not support a specified authentication ability, then the server rejects the connection with an ORA-28040: No matching authentication protocol error message. The client must support certain abilities of an authentication protocol before the server will authenticate. When an account password is changed, the earlier 10G case-insensitive password version and the 11G password version are both automatically removed. Note the following implication of setting the value to 12a: It may be necessary to reset the password for that account. Ensure the DBA_USERS.PASSWORD_VERSIONS value for the account contains the value 10G. To allow the connection, set the SQLNET.ALLOWED_LOGON_VERSION_SERVER value to 8. If the client uses Oracle9 i Database, then the client will receive an ORA-03134 error message. Releases of OCI clients earlier than Oracle Database 10 g and all versions of JDBC thin clients cannot authenticate to the Oracle database using password-based authentication. When an account password is changed, the earlier 10G case-insensitive password version is automatically removed. To take advantage of the password protections introduced in Oracle Database 11 g, users must change their passwords. The use of the Oracle instance initialization parameter SEC_CASE_SENSITIVE_LOGON is deprecated in favor of setting the SQLNET.ALLOWED_LOGON_VERSION_SERVER parameter to 12 or 12a to ensure that passwords are treated in a case-sensitive fashion. The SEC_CASE_SENSITIVE_LOGON initialization parameter enables or disables case sensitivity for passwords. If it is set as FALSE, then user accounts and secure roles become unusable because Exclusive Mode excludes the use of the 10G password version. The setting SEC_CASE_SENSITIVE_LOGON=FALSE must not be used because case insensitivity requires the use of the 10G password version. Note the following implications of setting the value to 12 or 12a: The ability for a client to authenticate depends on the DBA_USERS.PASSWORD_VERSIONS value on the server for that account.

The server is also more restrictive in terms of the password version that must exist to authenticate any specific account. This section lists and describes the following sqlnet.ora file parameters:Ī setting of 8 permits most password versions, and allows any combination of the DBA_USERS.PASSWORD_VERSIONS values 10G, 11G, and 12C.Ī SQLNET.ALLOWED_LOGON_VERSION_SERVER setting of 12a permits only the 12C password version.Ī greater value means the server is less compatible in terms of the protocol that clients must understand in order to authenticate.
