Form Exits when compiling with database link

Dear All,
I am using forms 6i and Oracle 10 G .I am using a databaselink in the form.When I compile the form , it exits from the form Builder.
I am able to use the databaselink from SQL.
Kindly help
Thanks

In forms 10g. Tnsname is picked from application server from <oracle_home>\Product\OraMidTier10gR2\NETWORK\ADMIN
As you have forms6i , I expect your client machine should have tns enrty for the SID what you are using in creating databaselink.

Data not visible in table o/p when compiled with webdynpro compiler

Hi,
I am using a Z BAPI to retrieve data from backend ECC6 server and show it using a VC application.
When I compile this VC application using FLASH(FLEX2), the data is shown in the table, whilst if the VC application is compiled using Webdynpro compiler, the data is not shown in the table.
The No. Of Rows parameter has been updated with 10.
Please suggest what can be done so that data is shown when compiled with Webdynpro compiler.

Ranu

Hi Ranu,
WebDynpro Compiler only supports Webservices.
You can look at the below link to get into full details -

Strange problem with Database LInk

Hi Everyone,
I have strange problem with Database Link in Oracle 11g Express Edition;
There are two computers: computer-server and computer-client. Tnsnames.ora are the same on both computers ie.
CT =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = krzysztof)(PORT = 1521))
(CONNECT_DATA = (SERVICE_NAME = XE)
I created database link :
Create database link zdalny
Connect to <user_id> identified by <password>
using ‘CT’;
Client can’t connect with server when I am using above command. But when I change “using” for using ‘krzysztof:1521’ or using ‘krzysztof’ or using ‘server IP:1521’ – everything is ok.
Why I am asking. Because in all materials which I am reading about Oracle command with using ‘CT’ should be working correct. But there is not. Do you know, why?
Thanks in advance and apologize for my English.

PS. I tried with using 'XE' - not working.Assuming that is the correct tnsnames, of course XE is not working. You don't have a tnsnames entry for 'XE'.
You need to be aware that when using a dblink, the client is the db in which the link is defined, not the desktop from which you connect to that database.
I think you need to start here:
http://edstevensdba.wordpress.com/2011/02/26/ora-12154tns-03505/
http://edstevensdba.wordpress.com/2011/02/09/sqlnet_overview/ (Help! I can’t connect to my database )
http://edstevensdba.wordpress.com/2011/02/16/sqlnet_client_cfg/ (Help! I can’t connect to my database (part duex) )
The fact that your client (db link) is a database doesn't change anything taught in the above.

Pragma error when compiling with SDK X

Hi,
I am trying to compile my plugin application (which compiled fine with the previous sdk) using the SDK X, but receive errors in CAVAlert.h on the exception handler construct DURING, HANDLER, END_HANDLER.
The errors are listed here:
Headers/API/CAVAlert.h:156:3: error: 'suppress' was not declared in this scope
Headers/API/CAVAlert.h:156:3: error: 'warning' was not declared in this scope

Headers/API/CAVAlert.h:165:3: error: 'ENDHANDLEROutsideHANDLER' was not declared in this scope
To compile against to SDK X all I did was:
1) Used PIMain.c from the SDK X API directory.
2) Changed ACRO_SDK_LEVEL=0x00090000 => ACRO_SDK_LEVEL=0x000A0000
3) Changed the include directories to point to the new SDK X directories
Is there another directive I must add to get the plugin to compile with SDK X?
My preprocessor list is as follows:
ACRO_SDK_LEVEL=0x000A0000
HAVE_W32API_H
PDMETADATA_HFT=1
PLUGIN=1
WIN32
WIN_ENV
WIN_PLATFORM
WXUSINGDLL
_CRT_SECURE_NO_DEPRECATE
_DEBUG
_WINDOWS
__GNUWIN32__

Codepage problem when compiling with fastjavac

Hi,
I'm getting the following warnings when compiling with fastjavac:
fastjavac: warning: Can't find codepage for "Cp1250" encoding.

How could I suppress these warnings?

I think you are posting it on the wrong Forum. This is for Forte 4GL not Forte for Java.

-Xlint warning when compiling with command prompt.

1 of the method i write in the program has a compilation warning when compiling with command prompt. When i compile the codes with the application i used to write the program has no error at all. Below is my code:
private static ArrayList readNum(String NumFile)
ArrayList key = new ArrayList();
String keyAttributes = readInput(NumFile);
StringTokenizer stk = new StringTokenizer(keyAttributes);
while(stk.hasMoreTokens())
key.add(stk.nextToken());
return key;
When i javac the program with -X;int, this errror occured:
warning: [unchecked] unchecked call to add(E) as a member of the raw type java.util.ArrayList
key.add(stk.nextToken());
^
1 warning
Anyidea how to solve this problem? Thanks for the help.

A quick google for that message would have told you that you're not using generics and the compiler complains about that.
Google for "Java Generics" to find out what all the fuss is about.

Form 6.0/6i with database Upgrade to Oracle 8i

Hi all,
I am planning to update our database from Oracle 7.3.4 to Oracle 8i (8.1.6).
Do you know that whether i need to recomplile all report (rep) and form (fmx) after grade?
For my past experience, all reports need to recomplile in REPORT 3.0 for change of table any table structure/move tablespace.
Best Regards

Hi Himanshu,
oracle forms6i and reports6i is not certified for Oracle 10g relese2 database,its only certified for oracle10g release1 with Patch17.
We ran in to same problem recently..
We got errors when we are compiling Forms and reports against Oracle10g release2.database
Error 00600: database internal error.
This is only happened with the few Forms and Reports which are having Database links(For those remote databases which were lower version than 10g relese2) in it.

Forms 6 not connecting with Database 10g

I can not connect Oracle forms 6 with database 10g

795192 wrote:
I can connect to sql plus but i cannot connect my forms 6 with database 10g. getting the following error:
ORA-12154: TNS: could not resolve service name=================================
ORA-12154: TNS:could not resolve the connect identifier specified
This error means one thing, and one thing only. The client could not find the specified entry in the tnsnames.ora file being used.
As a follow-on to that statement, remember that when you use a dblink, the database in which the link is defined is acting as a client to the database that is the target of the link. So in this case, the tnsnames.ora file on the host of your source should have an entry for your target db, as defined in the db_link.
And for the umpteenth time ... this error has NOTHING to do with the status of a listener. The connection request never got far enough to reach a listener. If anyone tells you to check a listener in response to ora-12154, they are not paying attention, or do not understand how TNS works. This error is the equivalent of not being able to place a telephone call because you don't know the number of the party you want to reach. You wouldn't debug that situation by going to the other guy's house and testing his telephone, or by going to the phone company and testing the switchboard. And you don't debug a ORA-12154 by checking the listener. If I had a top ten list of "Incredibly Simple Concepts (tm)" that should be burned into the brain of everyone who claims to be an Oracle DBA, it would include "ORA-12154 Has Nothing To Do With The Listener".
=================================
A couple of important points.
First, the listener is a server side only process. It's entire purpose in life is to receive requests for connections to databases and set up those connections. Once the connection is established, the listener is out of the picture. It creates the connection. It doesn't sustain the connection. One listener, with the default name of LISTENER, running from one oracle home, listening on a single port, will serve multiple database instances of multiple versions running from multiple homes. It is an unnecessary complexity to try to have multiple listeners or to name the listener as if it belongs to a particular database. That would be like the telephone company building a separate switchboard for each customer.
Second, the tnsnames.ora file is a client side issue. It's purpose is for address resolution - the tns equivalent of the 'hosts' file further down the network stack. The only reason it exists on a host machine is because that machine can also run client processes.
Assume you have the following in your tnsnames.ora:
larry =
(DESCRIPTION =
 (ADDRESS_LIST =
 (ADDRESS = (PROTOCOL = TCP)(HOST = myhost)(PORT = 1521))
 (CONNECT_DATA =
 (SERVICE_NAME = curley)
)Now, when you issue a connect, say like this:
$> sqlplus scott/tiger@larrytns will look in your tnsnames.ora for an entry called 'larry'. Next, tns sends a request to (PORT = 1521) on (HOST = myhost) using (PROTOCOL = TCP), asking for a connection to (SERVICE_NAME = curley).
Where is (HOST = myhost) on the network? When the request gets passed from tns to the next layer in the network stack, the name 'myhost' will get resolved to an IP address, either via a local 'hosts' file, via DNS, or possibly other less used mechanisms. You can also hard-code the ip address (HOST = 123.456.789.101) in the tnsnames.ora.
Next, the request arrives at port 1521 on myhost. Hopefully, there is a listener on myhost configured to listen on port 1521, and that listener knows about SERVICE_NAME = curley. If so, you'll be connected.
What can go wrong?
First, there may not be an entry for 'larry' in your tnsnames. In that case you get "ORA-12154: TNS:could not resolve the connect identifier specified" No need to go looking for a problem on the host, with the listener, etc. If you can't place a telephone call because you don't know the number (can't find your telephone directory (tnsnames.ora) or can't find the party you are looking for listed in it (no entry for larry)) you don't look for problems at the telephone switchboard.
Maybe the entry for larry was found, but myhost couldn't be resolved to an IP address (say there was no entry for myhost in the local hosts file). This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe there was an entry for myserver in the local hosts file, but it specified a bad IP address. This will result in "ORA-12545: Connect failed because target host or object does not exist"
Maybe the IP was good, but there is no listener running: "ORA-12541: TNS:no listener"
Maybe the IP was good, there is a listener at myhost, but it is listening on a different port. "ORA-12560: TNS:protocol adapter error"
Maybe the IP was good, there is a listener at myhost, it is listening on the specified port, but doesn't know about SERVICE_NAME = curley. "ORA-12514: TNS:listener does not currently know of service requested in connect descriptor"
=====================================

Hi,
This forum is for issues connecting to non-Oracle databases. As the problem is using PL/SQL to connect to another Oracle database then it would be better to post a thread in the PL/SQL forum -

Bug report: ube_ipa: internal error when compiling with -xO5

When compiling imlib2-1.1.2, one source file causes compilation to fail with the following error message:
ube_ipa: internal error
cc: ube_ipa failed for loader_tiff.c
The command which fails is (probably wrapped):
cc -DHAVE_CONFIG_H -I. -I. -I.. -I. -I.. -I../src -I../loaders -I../libltdl -I/usr/X11R6/include -I/usr/openwin/include -I/opt/csw/include -I/opt/csw/include -I/opt/csw/include -g -fast -xarch=386 -xstrconst -v -xildoff -xO5 -c loader_tiff.c -KPIC -DPIC -o .libs/loader_tiff.o
Changing -xO5 to -xO4 works around the problem. The source file in question is imlib2-1.1.2/loaders/loader_tiff.c
Patch 112756-10 has been applied, and doesn't correct the problem. GCC doesn't have any problem compiling the file.
A quick note to any Sun employees reading this: it took me 45 minutes to find somewhere to submit this bug report. Searching sun.com for "submit bug report" turned up many forum postings where people asked "Where do I submit bug reports?", a bug report form for Sun One Java Studio, and not much else. It might be in your interest to make submitting bugs easier.

Internal errors, such as the one you encountered, are generally considered compiler bugs. They indicate that the compiler reached an unexpected state and therefore bailed out. I opened bug 20703141: internal error: pic_relocs(): hh reltype? to investigate. I see the same error message emitted by the current Studio development release; I will update this thread if I find a work-around.
Thanks,
Mark

Could you please let me know how to solve this and how to create such location with OMB*Plus?
Thanks,
Sebastian

Hi David,
Thanks a lot for the tip. Now I was able to use this and using a registered location.
OMBCREATE LOCATION 'X' SET PROPERTIES (TYPE,VERSION,CONNECTION_TYPE, SCHEMA) VALUES ('ORACLE_DATABASE','11.1','DATABASE_LINK','MY_SCHEMA')
OMBCREATE CONNECTOR 'REGISTERED_LOC/X SET PROPERTIES (DATABASE_LINK_NAME) VALUES ('MY_DBLINK') SET REF LOCATION 'X'
OMBCOMMIT
OMBCC '/MY_PROJECT'
OMBCAC 'DEFAULT_CONFIGURATION'
OMBCONNECT CONTROL_CENTER USE 'owb_user/owb_user'
OMBREGISTER LOCATION 'X' REUSE
OMBCOMMITBut now my question is the following.
I am having problems to import the metadata from X.
When create a module (source), I am able to make "data location" from location 'X' but when I want to import a table from location 'X' is not possible, because it shows as a plausible metadata location as "REGISTERED_LOC"
Could you please let me know how to use 'X' as metadata location?
Thanks!
Sebastián

Ora-12154 problem with database link and transparent gateway

Hello,
I’m trying to make a communication between oracle and SQL server 2005.
I use oracle 10g E.E Release 10.2.0.3.0 and the transparent gateway for SQL server 10201_gatway_win32.zip.
Install:
The oracle database is installed into a server named ss-serv. This server has two partition disk C and E. Oracle database is installed in E and the gateway in C. There is already a database (instance) running in the oracle home (in E).
I configured the gateway as described into: http://download.oracle.com/docs/cd/B...3/conf_sql.htm.
In sql server 2005, there is a database running named ClientTricks.
I created a user named Avogadro with a login.
In the partition C where the gateway is installed, the file inittg4msql.ora is like this:
HS_FDS_CONNECT_INFO= ss-serv. ClientTricks
The file sqlnet.ora where the gateway is installed is configured like this:
SQLNET.AUTHENTIFICATION_SERVICES=(NTS)
NAMES.DIRECTORY_PATH = (TNSNAMES, EZCONNECT)
I configured the listener that is in the C partition where the gateway is installed, and the tnsnames that is in the oracle database in E partition disk like this:
Listener :
LISTENER=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=ss-serv)
(PORT=1521))
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=tg4msql)
(ORACLE_HOME=C:\oracle\product\10.2.0\tg_1)
(PROGRAM=tg4msql)
tnsnames:
mytg4msql=
(DESCRIPTION=
(ADDRESS=
(PROTOCOL=TCP)
(HOST=ss-serv)
(PORT=1521)
(CONNECT_DATA=
(SID=tg4msql))
(HS=OK))
After edited the listener, I stop and start the listener for the transparent gateway from administrative tools in the services.
Then, connected in oracle (in a database named fakeclient) I created a database link in sqlplus.The the dblink were created, but when I tried to querry some data from ClientTricks by executing the following instructions:
select * from s_client@dblink
i got this fatal and terrible error :
ora-12154 TNS:could not resolve the connect identifier specified
I verified all my procedure and stapes, all seems to be good. I did a tnsping of mytg4msql
I got this error in the command prompt:TNS-03505 fail to resolve name
Could someone help me ?
Sorry for my English ,I’m French
best regards

Hi Mkirtley,
i clarify you what i've done:
Pease have a look in the link in my first post. Then, i said that in oracle database home the listener is in port 1521
here is this listener:
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=PLSExtproc)
(ORACLE_HOME=E:\oracle\production\10.2.0\db_1)
(PROGRAM=extproc)
LISTENER=
(DESCRIPTION_LIST=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=TCP)(HOST=ss-serv)(PORT=1521))
(ADDRESS= (PROTOCOL=IPC)(KEY=EXTPROC0))
Here is the tnsnames.ora in oracle database home:
N.B in this ora file, there's already some descriptions for the database running, so i just add these lines under the description in ora file.Here is:
Jest=
(DESCRIPTION=
(ADDRESS_LIST=
(ADDRESS=(PROTOCOL=TCP)(HOST=ss-serv)(PORT=2000))
(CONNECT_DATA=
(SID=tg4msql)
(HS=OK)
for the listener of the gateway (installed in C partition):
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(SID_NAME=tg4msql)
(ORACLE_HOME=C:\oracle\production\10.2.0\tg_1)
(PROGRAM=tg4msql)
LISTENER=
(DESCRIPTION_LIST=
(DESCRIPTION=
(ADDRESS= (PROTOCOL=TCP)(HOST=ss-serv)(PORT=2000))
(ADDRESS= (PROTOCOL=IPC)(KEY=EXTPROC1))
here are all i did.
Best regards

ORA-00022 with Database Link and Trigger

Hello altogether,
I got a very strange behaviour with my oracle 10.2.
I have two nets N1 and N2, where N1 can access the servers in N2, but not the other way round. In both nets I have an Oracle database running (D1 and D2).
In N1 I calculate some data, which must be replicated to the database in N2. I do this by using triggers on my tables in database D1 copying the inserted or changed data to D2 by using a shared public database link.
This works fine most of the time. But sometimes I get the following error:
ERROR [STDERR] Caused by: java.sql.SQLException: ORA-02068: following severe error from D2
ORA-00022: invalid session ID; access denied
ORA-06512: at "CUSTOMER", line 13
ORA-04088: error during execution of trigger 'CUSTOMER'
When I use the database links manually, they work.
Any idea?
Thank you!!
Daniel

The ORA-02068 message might be important
02068, 00000, "following severe error from %s%s"
// *Cause: A severe error (disconnect, fatal Oracle error) received from
// the indicated database link. See following error text.
// *Action: Contact the remote system administrator.Have you searched Oracle support for any bugs associated with the ORA-02068?
Was the remote session killed, the remote database changed to restricted session, or bounced?

Stored procedure with database link with "from table(...)"

Hi guys,
I've been told I can't create views on a database by the design team and so have to use this stored procedure to obtain the values.
select HAN_ID, HAN_DS, GLOBAL_IN, LOCAL_IN
from table(cast(ODADMIN.ODP00002_QUERY.Execute001@DBLINK(11312,'EN') as
ODADMIN.ODP00002_001_Array@DBLINK)) WHERE LOCAL_IN = 'Y';I've been told that it works when you remove the database links (so on the actual database) when you remove the cast part. I've tried it with my link and with/without the cast part but it doesn't work. With the example above I get the error: ORA-00907: missing right parenthesis.
When I remove the CAST-AS and the additional parenthesis it brings i get the error: ORA-00904: "ODADMIN"."ODP00002_QUERY"."EXECUTE001": invalid identifier
When I do table( *"* ODADMIN.ODP00002_QUERY.Execute001@MWW_DEV(11312,'EN') *"* )... -- wrapping the call in speech marks I get: ORA-00972: identifier is too long
Anyone see what's wrong? Thanks for any help.

Hi Ben,
Asking now. By a view I mean one local to the database; I could create one on APEX but then I use the database link twice instead of just 1.
His reasoning Ben:
Firstly, Maintenance. We will have to maintain additional views (at additional code). Secondly, if the view has a JOIN, then you can't update through it (without complexities). If we have to get the View to pass the data to a Procedure (that's a pain). Also, standards..
All update occur via either a Procedure, or a Base view, across over 1000 tables
That's the standard, and doing things differently is costly long term
People will not know how it works, it will have to be explained, maintained..etc.
If the Application has the Business Rules, then updates via Base Views, that's a more standard way of developing. Also, if you update via this view, you'll update multiple rows in one call, which is in-effficient if only ONE row needs to change. Therefore, single row updates from the Application is more efficient
The procedure is as follows:
--SET SERVEROUTPUT ON
DECLARE
nPBusLoc       NUMBER(5):=11312;
sPHanId        VARCHAR2(3):='SB1';
sPLngId        VARCHAR2(2):='EN';
sPDesc         VARCHAR2(30);
sPAllowAlloc   VARCHAR2(1);
sPShowEnq      VARCHAR2(1);
sPAllowDel     VARCHAR2(1);
sPShowScan     VARCHAR2(1);
sPGlobalLocal VARCHAR2(1);
sPReturnCd     VARCHAR2(2);
sPReturnTx     VARCHAR2(100);

Called form crashes, when called with default option

Here is the problem statement.
My problem is regarding the called_form built-in function of Oracle forms.
I am calling call_form within a loop.
call_form('schdule_task');
In first iteration it opens the called form and when the user clicks on exit button it comes back to the calling form and starts next iteration.But in next iteration the called form comes up and crashes immediately, causing the application to crash.
The calling form does not get a chance to become visible because by default call_form executes with 'HIDE'(hide the calling form) option.
Now if I execute the above mentioned call_form statement with "NO_HIDE" option then the called form does not crash in any of the iteration and the loop runs fine till the end.
call_form('schdule_task',NO_HIDE);
What can be the problem? Is it related to call_form call or something else?
