Server Administration :: How To Connect Oracle Client To Remote Server DB
Jun 29, 2013
I'm trying to connect a oracle client application on the client machine to a remote oracle server on the server machine but i get a connection fail.
On the server machine I configured oracle server in the following way:
Installed oracle server. Created a database "DB_Test" with the database configuration assistant Created a LISTNER with the Oracle NET Manager with the following parameter:
Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521 Created "dbtest" service with the Oracle NET Manager with with the following parameter:
Service Name: "dbtest" Protocol: TCP/IP HOST: server pc hostname (ENZOVAIO) or server machine address ip (192.168.0.71) in the network lan Port Number: 1521
All services on the server machine are running and I opened port number (1521) in the router. On the client machine I installed SQL PLUS and SQL Developer.
With SQL Plus as by the official documentation I have entered the following command:
CONNECT username/password@[//]host[:port][/service_name]. In my case is:
CONNECT SYSTEM/oracledb@//ENZOVAIO:1521/testdb.
With SQL Developer I have entered the same parameter.
But with both SQLPlus and SQL Developer the connection fails.
all of the client cann't connect the db,and using sqlplus / as sysdba also cann't login there are many error of TNS-12535 and in the listener.log

I am trying to find the unix process for one of my application in the database but I am unable to view the same. To simulate, I did the following.
1. My database runs on different server. 2. I invoked "sqlplus" from another unix box to login to the database. 3. I found that the process id (ps -ef |grep sqlplus). 4. When I execute the below mentioned query it does not display the process id that I am looking for. But the osuser, username, program and machine details are correct. How can I know the process details from the database?
SELECT SYS.GV_$SESSION.OSUSER, SYS.GV_$SESSION.USERNAME, SYS.GV_$PROCESS.SPID, SYS.GV_$SESSION.MACHINE, SYS.GV_$SESSION.PROGRAM, SYS.GV_$PROCESS.PROGRAM ,SYS.GV_$SESSION.SQL_ID FROM SYS.GV_$PROCESS, SYS.GV_$SESSION WHERE SYS.GV_$PROCESS.ADDR=SYS.GV_$SESSION.PADDR and SYS.GV_$SESSION.USERNAME='TEST' and SYS.GV_$SESSION.MACHINE like '%hostname%'
We are unable to connect to Oracle 11.1.0.7.0 from Oracle Forms 4.5..However we are able to connect using Oracle forms 6i
Now Forms 4.5 is old and not supported, however apart from Tests I will need prove it to the higher ups...Do we have any link, document which will cover such compatibility issue?
After restarting the listener, we could connect using the connect identifier from the local server. However, when trying to connect from a remote client we received the error of "no listener". In the remote client the identifier is defined with host=ip_address. TNSping from the client to the host was successful.
When we changed listener.ora to host=up_address we could connect ONLY from the remote computer. Only after changing the host in tnsnames.ora file to the IP as well - we could connect from both the local server and the remote client.
I usually use host=localhost in the listener file (and the local tnsnames file) and never had this problem before.
I am trying to install Oracle client 11G software in AIX box. In /home/oracle, I find 7 profile files. I am not sure which profile file I am supposed to consider.
I am getting this error ( ORA-12516: TNS:listener could not find available handler with matching protocol stack ) When I am trying to connect to the server through my application in which I am using SOAP
I cannot run a Scheduler remote external job on Windows. Here's what I'm doing:
--Check that XDB isinstalled: desc resource_view --Check that MTS is running sho parameters dispatcher sho parameters shared_Server --Setup an http listening port: exec dbms_xdb.sethttpport(8080)
[code].....
This is the error:
orcl> select job_name, status, error#, actual_start_date, additional_info 2 from user_scheduler_job_run_details where job_name='TRYIT'; TRYIT FAILED -1.074E+09 15-JUN-11 02.16.54.583000 EUROPE/LISBON
[code].....
I am certain that the communications and the credentials are correct, I've tried variants and get different errors. I think the problem is the job action. I've tried running batch files as well as OS commands, same result. THere is nothing useful in the core dump. Is there perhaps a Windows specific technique for running external jobs? Some way of nominating the batch file, or specifying a command interpreter?
We have created a new db link. But we are not able access the remote database. When we are trying to access any table using db link system is getting hanged.
We would like to know what are the parameters/permissions which affect the db link access either at data base level or at server level.
One observation we made is that that particular db link is not getting dropped when we tried to drop it.
after a long time,(i never remember when was the last time i installed 9i)i was asked to install 9i.So, whether i install server or cilent i get this error <attachment>
after i ignore it and finished the installation,The server installation gets abruptly ended for the client i get TNS errors.
I have installed oracle 11g Release 11.1.0.1 on windows server 2008.I access this server from a client machine running on winXP through SQL PLUS. I wanted to shutdown and start DB server from this client machine. Accordingly i issued shutdown immediate command from SQLPLUS.
Now when i tried to start the DB with "STARTUP NOMOUNT" command i received error 12514. I understand this error means that the listener received a request to establish connections to a database but since DB services are not up and running, hence the error. So my first question is how do I resolve this error.
Continuing further, i tried to re-connect to the database as sys, and i received another error ORA-01041. So, my second question is why did i receive this error and again how can i resolve it
may be you can point me to relevant reference in Oracle documentation) how can i start and stop oracle from a client machine using SQL interface in CLI mode and windows environment and avoid this error.
Just wanted to know if 11XE (R2,32bit) will install and work correctly on Windows Server 2008 R2 x64?
I would like to install either the Oracle 11g Client and/or ODP.NET(x86 and x64) on the same machine, would this work? I cannot find any documentation regarding this and so far I am having some issues. At this point in time I have 11XE and ODP.Net (both x86) on this x64 machine under separate Oracle_homes and I cannot connect to the XE database from either SQLPlus client installed with the respective Oracle_Home..
Can I use a 32bit client to connect to a 64bit server?
i am using client-server environment without using a domain.On One computer i have installed Oracle 8.0.5 and developer 2000. and on client side i have installed form 6i. i have made a service (star) in Tnsnames.ora in client side.
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 migrated one database ( DB1) from old database server to new database server where user accounts were locked before migrating the database.But migration was successful and database and accounts got created in new database server.
In old database server , user accounts status is locked and in new database server user accounts are open but still i am unable to connect to database using new user in new database server.
why im unable to connect to database whose accounts are open?
last two years i am using oracle 9i in windows 2003 server but now i installed oracle 10g on another server (PC) , i want to connect 9i to 10g with same database and user .
i create new database (Student) using command line, now i want to connect with newly created database (using sys as sysdba), but again it directly connected with old database (ORCL). So what should i do to connect with newly created database (Student).
now DB is hanging; i am not able to connect both SQL and RMAN prompt. Is it possibel to move some old archives using ASMCMD prompt to datafile mount point location? Once i got some free space, then i can try connect RMAN and fire my script manually to take the backup and delete the same. ....
ASMCMD [+QSTAGE_T1_BACKUP_01/QSTAGE/ARCHIVELOG] > ls -ltr cdType Redund Striped Time Sys Name Y 2011_07_15/ Y 2011_07_16/ Y 2011_07_17/ Y 2011_07_18/ Y 2011_07_19/ Y 2011_07_20/ i have free space at mount point : +QSTAGE_T1_DATA_01/QSTAGE/DATAFILE
i need to backup the archives first before deletion..as those are required for Streams.
backup script:
run { backup archivelog all delete completed before 'sysdate-1'; }
note: i would like to remove the file which are older than one day
In one machine I have windows xp with Oracle 11.2.0.2 database installed and I am able to connect to the database using both sql developer and sql plus.
In another machine I have windows 7. I installed Oracle client 11.2.0.1, then using Net configuration tool, I installed both listener.ora and tnsnames.ora files.
Now, I want to connect to the database which is installed on windows xp from windows 7 using the oracle client. When I tried to connect, I got the following error :
ERROR:ORA-12560: TNS:protocol adapter error
In order to rectify the above error, I was making sure that ORACLE_HOME AND ORACLE_SID were properly set in the regedit file (under HKEY_LOCAL_MACHINE > SOFTWARE > ORACLE). The ORACLE_HOME was set properly. But I found ORACLE_SID missing. So I added ORACLE_SID environment variable in the registry and re-tried connecting to the database. But I am not able to connect. What else should I do in order to connect?
