In the below code, the application is crashing @ free(svcname). should we delete the out variable or not?
{
char* svcname;
if (OCIAttrGet(eventhp, (ub4) OCI_HTYPE_EVENT, (dvoid *) &svcname, (ub4 *) &sizep, OCI_ATTR_SERVICENAME, dm_infop->errhp) != OCI_SUCCESS) {
pinlog(PIN_FILE_SOURCE_ID, __LINE__, LOG_FLAG_ERROR, " Unable to get service name.
");
return;
}

I am completely new to anything with Oracle or OCI,
Also, basic information:
Language: C
Oracle DB version: 11g
Trying to use OCI
I am trying to write a client that connects to an Oracle database and gets some information (obviously). On the OCILogon() step, I need the username, password, and db address. However, someone said there will be a tnsnames.ora file, and that should be enough.I've searched online and I have not been able to find anything that relates OCILogon() to tnsnames.ora, so here are my questions:
1) Can OCILogon() use tnsnames.ora at all?
2) Is there any other function that I should use instead of OCILogon() that would work with the tnsnames.ora
I am attempting to port some Pro*C code from Tru64 to AIX 6.1.I have compiled the PRO*C into an executable which is then called as follows:
host$ CJSPC004 /@WHDA 19/11/2012
Starting module : CJSPC004
Connected to the database
Running database procedure cjspk003.p_create_job_schedule
Module CJSPC004 completed successfully
However, when querying $? to get the status of the last command I get a non-zero code even though everything has worked.
host$ echo $?
39
On Tru64 this works fine with the echo $? returning a zero as expected:
host$ echo $?
0
The PRO*C was compiled using gcc
Our API supports Oracle 11.2g but uses OCI v8 yet.This means I cant activate client caching as a new feature ? We should update to OCIv11 ?
View 5 Replies View RelatedActually i am not using OCI directly. I have a Delphi application in which I would need to clone an open db connection. Not only username, password, and target database (this is easy and i already do that).
What I would need is also inherit context variables and global temporary tables content status at the moment in which the cloning operation takes place. It seems a very difficult, if not impossible, thing to achieve.
We have a occi application which is linked dynamically to occi lib on Solaris. Now during build we linked it with occi of Oracle 10.2.0.4 client but we want the same build to be able to run under Oracle 10G client as well as Oracle 11G client. But it seems that occi is not forward not backward compatible as name of dynamic occi lib has a version in it.
e.g
md1sisun26:/tools/oracle/10.2.0.4/lib->dump -Lv libocci.so
libocci.so:
**** DYNAMIC SECTION INFORMATION ****
.dynamic:
[INDEX] Tag Value
[1] INIT 0xc6110
[2] FINI 0xc62b8
[code]...
As you can see when we run our occi application under Oracle 11G client it fails as there is no libocci.so.10.1 .
I am using OCI and instant_client (11.2.0.3.0) in my C++ program (on Windows 7) to connect remotely to 11G database. While doing a connection using server name as well as servername:port/service_name as connection strings, I am getting error of ORA-12504 TNS:listener was not given the SERVICE_NAME in CONNECT_DATA. According to instant client FAQ & white paper at [URL]..., no tnsnames.ora is required for instant client. Then why could I be getting this error? I ensured that only the instant client directory is in Path environment variable. There was a ODBC driver installed on this same host.
View 3 Replies View RelatedI wrote a simple OCCI program and ran valgrind with it. I got some memory leak in the program. I tried to search around but couldn't get any answers. I have tried to compile the program using gcc version 4.5, and icpc version 12.0.4 and they both gave the same errors. The OS I am using is RedHat Linux 6.1.
#include "occi.h"
#include <iostream>
#include <string>
int main() {
oracle::occi::Environment *theOCCIEnvPtr = NULL;

We have code that occasionally errors with ORA-12151, with tracing indicating some funk surrounding OCI calls to OCIPing(), OCIBreak(), and OCIReset(). What the code is trying to do here is release a connection from a pool (our implementation, not OCIPool) and before releasing it trying to make sure nothing is actively running on the connection etc. The environment is created in THREADED mode (ie not non-blocking).
Reading the documentation its not really clear to me if OCIBreak() and OCIReset() are really intended to be called while in THREADED mode.
Is it a bad idea to call break/reset as part of a general connection-reset routine?
The basic control flow (minus error handling etc) is:
<pre>
reset() {
int rc = OCIBreak(connection_, err_);
rc = OCIReset(connection_, err_);
if (OCIPing(connection_, err_, OCI_DEFAULT) != OCI_SUCCESS) {
return errors;
}
return 0;
}
</pre>
I install Oracle instant client 11g in my Windows 7(32bit), and use MSVC6++ to test program occidml.cpp, compile is no problem, but when I run it, it crash on create Connection. I have tried to link with different version of OCCI library ( v8,v9), but all crash on create Connection.
View 0 Replies View RelatedI am trying to fetch the data from system table "FLOWS_020100.WWV_FLOW_ACTIVITY_LOG1$" in Oracle Express edition 10.2.0.3 database, using the OCI library on Windows with C++
This table has a TIMESTAMP column of date type.
I've the following query as below:
select TIME_STAMP from FLOWS_020100.WWV_FLOW_ACTIVITY_LOG1$ where TIME_STAMP > to_date('31/OCT/12 23:59:59', 'DD-MON-YY HH24:MI:SS') order by TIME_STAMP asc;
For this, first I am preparing the query as below:
select TIME_STAMP from FLOWS_020100.WWV_FLOW_ACTIVITY_LOG1$ where TIME_STAMP > :PKVAL order by TIME_STAMP asc;
Before calling OCIExecute(), I am setting the PKVAL buffer to following value:
"to_date('31/OCT/12 23:59:59', 'DD-MON-YY HH24:MI:SS') "
& calling the OCIBindByName function with data type as SQLT_DATE.
But when the OCIExecute is called, my program crashes with access violation
what is the correct way to pass the date value in query to OCI? How do we bind the date values?

There are only OCI headers in 9.2.0/rdbms/demo directory in our installation of Oracle 9.2:
9.2.0/rdbms/demo/ocixad.h
9.2.0/rdbms/demo/oci.h
9.2.0/rdbms/demo/oci1.h
...
In Oracle 10.2 installation there are OCI headers in rdbms/public directory:
10.2.0/rdbms/public/ocidem.h
10.2.0/rdbms/public/ocidfn.h
10.2.0/rdbms/public/ocikpr.h
10.2.0/rdbms/public/oci.h

What should be installed additionally to have OCI headers in rdbms/public in Oracle 9.2.0?
I am having an issue to connect my C++ application to my Oracle DB. When my code calls
oracle::occi::Environment::createEnvironment(),
I get an error "ORA-01804: failure to initialize timezone information".
The application works on other people's Windows machine with their Oracle DB. But it doesn't work from my machine connecting to their Oracle instance. So I guess the issue does not come from my instance but rather from my Oracle dlls maybe?

SP2-1503: Unable to initialize Oracle call interface
SP2-0152: ORACLE may not be functioning properly
But the solution people have proposed into the forum are:
1 - check the environment variable Oracle_home and modify if it ending by ""
2 - or try tho run my promt command as Administrator.
I try the both, but only the second works. while now i don't understand why it works when i start the promt command as Administrator and why it no works when i don't run it like administrator. Another thing is i am the only user of my computer, i have only one session (administor session).
In my application, when I passed a Type Array as parameter to the stored procedure and when the Type Array is large enough(normally 3000 type objects， each objects has about 15 attributes), the OCIObjectSetAttr performance deteriorates large enough from below 1 millisecond to 1~3 miliseconds.

Here are the relevant tables to the triggers I'm having trouble with.
create table profile
(
userID number(10),
uname varchar2(64),
email varchar2(32),
password varchar2(32),
date_of_birth date,
[code]...
Here's the triggers I currently have that doesn't work.
create or replace trigger DropAccount
after delete on profile
FOR EACH ROW
BEGIN
delete from groupMembership where (userID = :old.userID);
END;
The DropAccount trigger's purpose is to delete all the records from groupMembership that contains the userID of the person deleting his/her own account. It appears to work when I run the following statements in sqlplus:
delete from profile where (userID = '1');
select * from groupMembership where (userID = '1');
But when I try to delete an account through a java interface using JDBC I get the following error:
Machine Error: java.sql.SQLException: ORA-04091: table *****.GROUPMEMBERSHIP is mutating, trigger/function may not see it
ORA-06512: at "*****.DROPACCOUNT", line 2
ORA-04088: error during execution of trigger '*****.DROPACCOUNT'
The java function basically just executes a delete statement.
I have a package includes 22 functions, each function just returns a sql template (clob type).
I also have a stored procedure called query_builder, query_builder has applicationName and statementName as parameters. I need to call these functions in the package based on the given applicationname and statementname.
CREATE OR REPLACE PROCEDURE Query_builder (ApplicationName varchar2, StatementName varchar2) IS
SQLSkeleton varchar2;
BEGIN
PackageName := ApplicationName||'_SKELETON;
SQLSkeleton := PackageName.StatementName; -- I know this will not work, but how can i call these function dynamically?
