Hi all, I've a perfectly running Oracle 12c database installed in my machine till friday, but when I started my machine today morning, I'm able use my sqlplus but when I tried to connect to the DB using sql developer it is throwing me an error like:
An error was encountered performing the requested operation:
IO Error: The Network Adapter could not establish the connection
Vendor code 17002
I restarted the services in windows, tried lsnrctl start and all commands, I observed one thing that when I start the service of OracleOraDB12Home1TNSListener from the services.msc window it is just started and when I refreshed its just stopped.
Here are my tnsnames.ora file contents:
LISTENER_ORCL =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
ORACLR_CONNECTION_DATA =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
(CONNECT_DATA =
(SID = CLRExtProc)
(PRESENTATION = RO)
)
)
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
pdborcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL=TCP)(HOST=localhost)(PORT=1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = pdborcl)
)
)
and my listener.ora looks like this:
# listener.ora Network Configuration File: D:\app\user\product\12.1.0\dbhome_1\network\admin\listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = CLRExtProc)
(ORACLE_HOME = D:\app\user\product\12.1.0\dbhome_1)
(PROGRAM = extproc)
(ENVS = "EXTPROC_DLLS=ONLY:D:\app\user\product\12.1.0\dbhome_1\bin\oraclr12.dll")
)
)
ADR_BASE_LISTENER1 = D:\app\user\product\12.1.0\dbhome_1\log
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = BT-R4P9)(PORT = 1521))
)
)
ADR_BASE_LISTENER = D:\app\user\product\12.1.0\dbhome_1\log
I tried to solve it from my end, but in vain.
Can some one suggest me what should I do. Thanks in advance.
