Unable To Connect DB From LAN PC?
Mar 12, 2013
I hv no problem connecting oracle at localhost. but when connecting using another pc on the same LAN, the sqldeveloper returned an error saying
IO Error: The Network Adapter could not establish the connection on the linux where oracle installed, iptables is disable, but firewalld is enabled, so I did a
'firewall-cmd permanent zone=home --add-port=1521/tcp'
yet the remote pc still prompt the same IO error. what should I do to have oracle accept connection from the LAN and WAN ( I hv setup virtual server on router)

I have installed a database in D drive. I want to create another database in the same machine. I tried installing the new database using DBCA. Installation was ok. I added entry in TNS file.
When i try to login to this new database from other machine, i am unable to connect to this database. I made an entry in TNS on my local machine. It says the user id /password is wrong, even though they r correct. I am using the same password to delete the database.

I installed 10.2 client on Windows 2000 Terminal Server. I created the system dsn odbc connection. When connected to the terminal server via RDP as a domain administrator, the odbc connection functions appropriately. When connected to the terminal server console as a standard user, the odbc connection functions appropriately.When connected to the terminal server via RDP as a standard user, I get the error: "Unable to connect SQLState= IM004 [[Microsoft]][[ODBC Driver Manager]] Driver's SQLAllocHandle on SQL_HANDLE_ENV failed"
I have reviewed the numerous other posts regarding this error and I've executed the following recommendations: My oracle_home is defined first in my path environment variable (path - c:oracleclientin;). I select my folder options (there is no security tab, windows 2000) I select sharing, then permissions. I allow 'Everyone' and 'Authenticated Users' full control, change & read permissions. I reboot the server.

I installed Oracle 10g XE and Toad 10.5 in my home system.I am able to connect to Oracle from Oracle XE homepage and XE SQL command line but when I try to connect to Oracle from toad 10.5 I am getting the error 'TNS: could not resolve the connect identifier specified (XE)'.From toad I tried direct and TNS options but it did not work. My tns ora file looks like below.
XE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = Anu-PC)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = XE)
)
)
TNS_ADMIN variable has correct parameter and Toad is directing the correct TNS file. I tried changing hostname with my system's ip but still I am unable to connect to Oracle from Toad.

Database is up and running and client machines able to do TNSPING; But when users try to connect the database thro SQL DEVELOPER, they are getting below information:
your database connection has been reset. Any pending transactions or session state has been lost.in the database server, SQLNET.ORA reads as below:
> more sqlnet.ora
AUTOMATIC_IPC = ON
names.directory_path = (TNSNAMES,EZCONNECT)
names.default_domain = world
name.default_zone = world
sqlnet.expire_time = 15sqlnet expire time shows 15 min.
normally this error willbe suppressed if user tried after some time. But now we get this error for more than 2 hrs.

We have the Oracle 11g XE database installed on a Windows 7 laptop. The Oracle XE database runs fine when the laptop not connected to a network, when connected to our corporate lan, or when connected to a cable-modem. However, when running under the Cisco AnyConnect VPN client, we are unable to connect to the Oracle XE service.
I have tried to resolve this, but am stuck. I do not if this issues is caused by:
1. There is no IPv6 address listed for the AnyConnect VPN (from ipconfig /all)?
2. Something regarding split-tunnelling that must be configured on the VPN?
3. Can the Oracle XE database run under an SSL VPN?
Below is the output of when I try to connect the Oracle XE service via sqlplus.
