C++ Call Interface :: Calling OCIBreak() And OCIReset() From A Threaded Context
Aug 6, 2012
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:
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
Actually 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.
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.
I 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.
int main() { oracle::occi::Environment *theOCCIEnvPtr = NULL;
[Code] .......
and one of the leaks is :
==9744== 32 bytes in 1 blocks are definitely lost in loss record 61 of 224 ==9744== at 0x4A07279: malloc (vg_replace_malloc.c:263) ==9744== by 0x62D9147: slzsetevar (in /apps/oracle_client/libclntsh.so.11.1)...
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.
I 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:
I want to monitor the stream activity with strmmon tool. How to compile the strmmon.mk? I was seeing with visual studio command prompt but it does not work properly.
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 10.2.0/rdbms/public/oci1.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?
I am in the process of converting my skill in oracle and this time PRO*C from Windows to Linux. I have oracle 11g R2 installed on a UBUNTU (12.04) server and have installed the instant client as described in
[URL]
This has a query which will run in SQLPLUS but fails with PRO*C

I work with oracle 10g, on windows 7. sometime when i try to start my sqlplus in prompt command this message display.
C:UsersSony>sqlplus 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.
when i try to connect with sqlplus or toad then i get an error

and i want to tell what i do before it-my all files were be converted in .FLT then i shorted out this problem after that when i tried to connect with sqlplus or toad then i get above error.and i have restarted my system but throwing same error.
i tried creating an context index. But it is aborted in the middle. do to reuse the spce i want to drop the index. But it shows an error that " cannot drop index marked as process" how to delete the index.
Am trying to use the SYS_CONTEXT variables inside a trigger. After reading the documentation I found that the below query when used inside the trigger code will return the trigger owner.
Select Username from User_Users
Will any of the below variables return the trigger owner when used inside the trigger code
sys_context('USERENV','CURRENT_USER') or sys_context('USER','CURRENT_SCHEMA')
I am trying to implement a Jtree with Context Menu. When Context Menu is implemented the nodes wont expand or collapse.This happens with Sample Trees Packaged application for Project Documentation tree.
I'm trying to find out if I can create a context sensitive menu in Oracle Forms 10g. So far I haven't found much in the way of info. where I can find some sample code or a demo I can learn from?
The idea being that when a user right clicks an item they are then presented with relevent options for that item.
Create a table with 100 records.Then write a BULK COLLECT Cursor that can reduce the number of context switches by using a bulk fetch to query records in sets or all at once.
I've been successfully setting up text indexes on multiple columns on the same table (using MULTI_COLUMN_DATASTORE preferences), but now I have a situation with a one-to-many data collection table (with a FK to a lookup table), and I need to search columns across both of these tables. Sample code below, more of my chattering after the code block:
CREATE TABLE SUBMISSION ( SUBMISSION_ID NUMBER(10) NOT NULL, SUBMISSION_NAME VARCHAR2(100) NOT NULL ); CREATE TABLE ADVISOR_TYPE
[code]...
I've looked at DETAIL_DATASTORE and USER_DATASTORE, but the examples in Oracle Docs for DETAIL_DATASTORE leave me a little bit perplexed. It seems like this should be pretty straightforward. I'm trying to avoid creating new columns, and keeping the trigger adjustments to a minimum.
We have implemented PeopleSoft with an Oracle database. What I need to do is provide clients with access to information stored in that database. Some additional information may come from other external databases, however for right now I am just trying to crawl, not run.
I am working on getting table information from the PS provider, so that I can understand what information is available. I am also working with the clients to determine if there are pieces of information that they need access to which are not currently native to the PS implementation. I need to identify these for step 2 of the process. My superiors were looking at using an SOA architecture using SOAP to move the data. I am open to suggestions and since the project is in its infancy, I have time to alter perceptions before it is too late.
I am doing a research for our next project.MIGRATING oracle forms6i to java/apex/adfi've gather documentations to present to my boss.but she wants an actual(hands on) migration without purchasing yet.
application that i can test?Is FORMS to .XML to JAVA? is that possible ?where topic my message belongs to.(that's why i've put in GENERAL topic)
have created or used a JavaBeans can interface with OpenOffice?
I modified the java classes and finally managed to create a document. Odt OpenOffice Writer and launch from Eclipse. If I am not using the libraries oooBeans but there are 2 problems now:
1. For known issues I had to set the Java class path of the folder where you have OpenOffice executables and should be changed ...
2. I created a. Jar file executable, but I do not know how to integrate Oracle Forms and use it as JavaBeans. Perhaps this step you're more prepared
