Recently at a customer I was confronted with a problem of restarting the Oracle Database 12c automatically on a Windows Server 2008 R2 x64.
\nI installed Oracle 12.1.0.1.0 with a user of service in a domain who has member of the Group ORA_DBA. The authentication service is correctly set with the NTS parameter in the sqlnet.ora file.<\/p>\n

This Installation has been successfully but after a reboot we can see the database are not OPEN.

\nA restart of the service doesn’t work. When we restart the service, no commands are sent to the database instance. <\/span><\/span>
\nUnfortunately w<\/span>e find<\/span> no information<\/span> in the<\/span> alert<\/span> log concerning this problem.<\/span><\/span><\/p>\n

The Oracle Service in the services.msc have been correctly configured for a Automatic restart :
\n\"services.msc\"<\/a><\/p>\n

Solution<\/h2>\n

This problem provide of the parameter SQLNET.OUTBOUND_CONNECT_TIMEOUT in the sqlnet.ora file. This parameter is to specify the time for a client to establish an Oracle Net clients to the database. The outbound connect timeout interval includes the time taken to be connected to an Oracle instance providing the requested service.<\/p>\n

If you want restart automatically the database on Windows environment you should modify the value at “0” or comment the parameter SQLNET.OUTBOUND_CONNECT_TIMEOUT:
\n
\n# ****************************************************************************
\n# Specify the time for a client to connect with the database server
\n# and provide the necessary authentication information
\n# unit in seconds
\n#
\nSQLNET.INBOUND_CONNECT_TIMEOUT=60
\n# ****************************************************************************
\n# Specify the time for a client to establish an Oracle Net connection
\n# to the database, superset of the TCP connect timeout ( i.e : 8min on Linux)
\n# unit in seconds
\nSQLNET.OUTBOUND_CONNECT_TIMEOUT=0<\/strong>
\n<\/code><\/p>\n

After a reboot, If you have change the value of this parameter in the sqlnet.ora file, the database has rebooted automatically and successfully:
\n
\nSQL> select INSTANCE_NAME, STATUS,STARTUP_TIME,VERSION from v$instance;
\n.

\n<\/code>
\nI have open a Service Request to Oracle Support for this bug, I wait for a patch update for fix the bug on Windows environment.<\/p>\n

The bug is fixed on Oracle 12.2 but on the release 12.1.0.1 the patch is not available specifically for Microsoft Windows x64 (64-bit). The bug is in Development Working status.<\/p>\n
