Windows :: No Connection When Specifying Database Name
Jul 21, 2010
I have an issue with an Oracle 9 database where I can connect if I do not specify a database to connect to but when i do specify one i get an error. For example, my database is called WEB. If i open sqlplus and type connect username/password it will connect fine. If I type connect username/ password @web I get an error.The full error that appears in the log is:
TNS-12500: TNS:listener failed to start a dedicated server process
TNS-12546: TNS:permission denied
TNS-12560: TNS:protocol adapter error
TNS-00516: Permission denied
32-bit Windows Error: 5: Input/output error
I have checked the tns entries and listener file and both are fine. Here are the entries:
TNSNAMES:
WEB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = localhost)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = web)
)
)

TOAD 8.6.1 has an option of showing windows by connection. It is useful when there are multiple connections and, choosing one of these, all windows that belong to other connections are minimized.
Its icon looks like this:
Does TOAD 9.1 have the same option? I'm unable to locate it in options, toolbar customizations or elsewhere.
TOAD 9.5 Release Notes document says that "'Connection list' dropdown button has been restored and can be added to the Toad toolbar.". If I understand it correctly, it says that previous version didn't have that dropdown button, but 9.5 does.
In another words ... 9.1 might not have it at all.

I have an Oracle database (9.2.0.7) installed on a HP-UX server.When trying to access this database from another HP-UX or Linux server, connection is fine. But when trying to connect from a Windows based client, connection is very slow (almost 1 minute to return the result of a 'select count(*)' like query, which is immediate from the Linux client).
Here are some facts I can add :
- Clients and servers are on the same network segment (it is not a network matter)
- No matter which client version I use, there no difference
- I tried to know what happens on the Oracle server when performing my sample query using tusc command : the result is that the server is performing exactly the same actions when sending my query from a Linux client or a Windows client
- The only relevant difference seems to be the client OS

I have 3 questions.
I have 11.2.0.1 database on Windows 2008 R2 SP1.
1) While connecting to the database as sysdba (sqlplus "/as sysdba"), it takes about 12 to 15 seconds what things I need to check/change so that connection will be faster?
2) Also, I have read somewhere that changing the sga/memory parameters connecting to the database. is it true?
3) This is not concerned with above 2 questions. What should be the memory parameters size for a 8 gb database?
What I have is:
Total System Global Area 1068937216 bytes
Fixed Size 2182592 bytes
Variable Size 1027605056 bytes
Database Buffers 33554432 bytes
Redo Buffers 5595136 bytes

Our database is on one site . There is a form which is used by users on another site. The internet connection is lost sometimes and the form that they use looses connection to the database. What I would like to do on the form is whenever the connection is lost to the database i,eORA-03114,I want to reestablish the connection so that the form can be used by users all the time.

The problem i mentioned in my last posting "CRS installation/PRIF-10: failed to initialize the cluster registry" was due to the fact i was using Redhat Linux 9 that seems to have some missing packages. I installed White Box RH 3 and everything worked fine.
if it's possible to connect to a 10g RAC database using the jdbc java thin client. the java thin client requires an ip, and database sid. I am running a two node cluster and i have two ip's and a service name that uses TAF option.

I´m just having a problem whit the connection between Oracle Forms 6i and Oracle Database 11G. Is just when i login to the database schema i cant log in using Forms.
TNS Names its already configured, No problems when i log in using Toad and using the TNS Names from Developer's 6i tool. I can log in just when i change the schema(user) password from the database (thats the rarest thing) and log into the application.
So whenever i want to login to the application i must to change the schema password, i need to use it directly.

Just installed the new 2.0.8 version. Its been a while I am interested on using PM for our company.The problem I have is creating an Oracle DB connection. When I create a new Oracle DB connection, and test it, Steps 3 and 4 fail.What is strange is that I followed the following procedure in PM 1.9-825 and worked fine. I am wondering if something changed in the new PM 2.0.8 version (I noticed that php_oci8.dll was commented out in php.ini).
Oracle Version is 10GR2
PM installed on clean XP sp3
1. Got a new Windows XP SP3 PC
2. Installed PM 2.0.8
3. Edited php.ini and uncommented [PHP_OCI8] and extension=php_oci8.dll
4. Installed oracle instant client “instantclient-basic-win32-10.2.0.5” in c:oracle
5. Installed oracle instant client “instantclient-sqlplus-win32-10.2.0.4” in c:oracle
6. Added c:oracle in PATH environment variable
7. Created ORACLE_HOME = c:oracle environment variable
8. Added TNS_ADMIN = c: environment variable
9. Copied working tnsnames.ora file into c:
10. Rebooted.
-------------------------------------
1. Tried sqlplus connection to my oracle db and worked.
2. Launched PM
3. Created a new process
4. Created a new DB connection as follows:
a. Engine:Oracle
b. Server:192.168.xxx.xxx
c. Database name: my_name (where my_name appears in tns_names.ora)
d. Username:my_username
e. Password:my_password

I'm getting the error messaage:
Database Connection failure. Reason: java.sql.SQLException: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist SVR4 Error: 2: No such file or directory
I'm not an Oracle expert, but I have research a little and seems that the SID could be wrong or that the DB is down, in fact I have already checked trhe server but everything seems normal to me.

[URL]... says that session memory is maintained in the PGA (unlike shared server) and then gives a calculation for memory usage that I don't understand: it suggests that instead of there being one PGA per session, there is one PGA per pooled server plus a small allocation of 35k per session, but this is not what I see.
It's easy to demonstrate. As sys,
exec dbms_connection_pool.start_pool
and then launch any number of session with
sqlplus scott/tiger@127.0.0.1:1521/orcl:POOLED
and you'll see a process called Lnnn launched for each session:
[code]...
There is a mention of a process called the connection broker, but I can't see this in v$process.There is more detail in the OCI developers guide [URL]... which goes beyond my knowledge of application development.

Am running forms 10g on windows vista service pack 1 and am having problems with the FRM-40514 error. (Operation requires a database connection).
I can connect quite alright from form builder, but when i run a form it request for login credentials again. I dont understand why this is so, when am already logged on in form builder.I tried to tacke this by creating the following
DECLARE
Uname VARCHAR2(80);
Pword VARCHAR2(80);
cn VARCHAR2(80);
BEGIN
--pause;
--logout;
--message ('Logging out');
--synchronize;
[code]....
This code suppreses the logon screen and runs the form without logging on to the database. I know this because when I try to enter and execute query it brings up the message: FRM-40514: Operation requires a database connection.

I am having problem with my tnsnames.ora file.seems the file cannot handle connection information for more than one DB. It worked fine in the beginning, after that, whenever i had to connect to a DB, i had to keep switching and renaming 5 files, with respect to whichever database I want to connect to. this is the entries in the file, for 2 D's and it wont work, with just one in each it works, but not for two...
newtpt =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS =
(COMMUNITY = tcp)
(PROTOCOL = TCP)
(HOST = ipadd/virtualname)
(PORT = 1521)
[code]....
I am sure, nothing wrong with teh IP/virtualname, cause with just one of these in the file, they work excellent.I tried leaving line between the connection strings for each DB, without leavin lines, etc..
