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.
I am using OCI 11gR2,
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
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;
}
free(svcname);
}
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.

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;
}

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).

How to call a function with a row type return in an Oracle select statement.
For e.g. :
If I had this function with a rowtype return:
------------------------------
create function abc
return xyz%rowtype
is
rec xyz%rowtype;
begin
select * into rec from xyz where col1 = n;
return rec;
end;
--------------------------------
How could I use this in a select clause, as there is a multi column return by the function ?
I'm trying to use MULTISET UNION to append several collections into a single recordset.The select queries shown for the CURSOR are simple beta versions of the real queries which have about 350 fields to each of them. I will be appending data from 15 of these queries which each will with no more than 20 records per query into a new single recordset (not sure if 'recordset' is the correct phrase or term for what I mean, it could be ARRAY, OBJECT, COLLECTION or something else all together).
Here is text of the ERROR message:
ORA-06550: line 63, column 1:

I am using Release 11.2.0.3.0 - 64bit Production version of oracle. Now we are having 3-tier architecture, (firewal/web/app/DB).Now i saw , some of the 'sql' queries, running till ~10hrs in my database and those are part of application(module JDBC THIN CLIENT). After had a talk java guys, they ask to kill the sessions specific to those queries. They are part of search TO, in which user put some large values for the date range and went to other TAB, but these queries gets running infinitely in the database, and user is not interested in the result set.
So how to avoid these things, as because in past, our database has suffered resource contention leading to application slowness. So i was planing to set different timeouts using 'database resource consumer group' for online user request and batch request depending on the app server(that is by machine names) request.
So i have done below set up in my local to test one scenario, in which i will try give a database call from difference machine, and it should get timeout after the specified duration. But its not working , as expected. The calls from the specified machine are not getting assigned to the created 'Consumer group'.
Begin
-- create the pending area
dbms_resource_manager.create_pending_area();
END;
/
BEGIN
-- Create the consumer group
[code]....
After this when i am verifying calls from machine, 'LR9XY7T8' they are belongs to the consumer group 'OTHER_GROUPS' and sql query not getting timed out within 60 seconds as mentioned.
I have started reading ORACLE 11g R2 PL/SQL programming doc, and I am stuck at bind variable. I just copied the example in the books and found error -
First I have written below procedure and compiled successfully -
CREATE OR REPLACE PROCEDURE FORMAT_STRING ( string_in IN OUT VARCHAR2) AS
BEGIN
string_in := '[' || string_in || ']';
END FORMAT_STRING; Then I have written below function and also compiled successfully -
create or replace function join_strings (str1 varchar2, str2 varchar2)
[code]......
I have a pkg with a procedure that uses dbms_sql to process a varchar2_table. Each record in the table is a delimited string, such as "Priority^2", or "Destination^7". The goal is to split that string on the hat and update a record in the panelfield_users table. It works perfectly if I replace the first substr/instr on :pColumn with a hardcoded number, so I know that the binding is working to that point. It is only when I try to get the latter half of the string that it chokes. I keep getting a "invalid number" error. The displayorder field is an integer field and all values will be 3 digits or less. If I pull the sql string out into an editor, it runs just lovely.
The pertinent code is:
C := DBMS_SQL.OPEN_CURSOR;
DBMS_SQL.PARSE(C,'update panelfield_users set displayorder = to_number(substr(:pColumn, instr(:pColumn, ''^'') + 1)) where userid = :pUID and fieldid = (select fieldid from panel_fields where upper(panelname) = upper(:pPanel) and upper(modulename) = upper(:pModule) and upper(field_displayname) = upper(substr(:pColumn, 1, instr(:pColumn, ''^'')-1)) )
