"SQL-02103: Inconsistent cursor cache." error on dual processor multi thread apps

I have a C++ with Pro*C++ COM object running on a Win2000 OS on
a dual processor Middleware. The program is being called by a
service in a multi threaded way. An oracle error like ORA-2103
and SQL-02103 will be generated after running the program. We've
tried putting mutex on every SQL statement in Pro*C and it works
but the systems became very very slow. We concluded that the
error might be cause by a collision of threads accessing the
same Table or different tables having foreign constraints. This
is so because the error keeps coming from a statement accessing
Table A and following errors comes from a Table B having a
foreign key on Table A.
Our only solution now is to put Mutex on Statements accessing
same tables or tables with foreign constraints but this will
make our system run very very slow. I dont know if the problem
is in our Oracle Database because we already upgraded our system
from 8.1.6 to 8.1.7. The wierd thing on this is that the system
is running smoothly without oracle errors on a SINGLE PROCESSOR
Middleware. Hope you can give me any insights on this problem.

Inconsistent cursor cache error still presisting

Hey I have asked this question before but no solution has been provided me. I have been facing a very serious problem. I have oracle 11g on windows 2003 on 64 bit machine. With 2 processor 8GB RAM. Sga/pga automatically features turn on and 6GB assign to memory_max_target, memory_target . My problem is when I run update 600 hundred statements in one go and every update statement update record between 1 to 30000 and after 20 records I use commit. But after 20 to 30 record oracle go down (shutdown) when i check alert log It advise to check Trace file and in trace file I got this error ORA-02103: PCC: inconsistent cursor cache (out-of-range cuc ref). I turn on my cache sharing to force but no way. Is there any other fast way to update records??
cursor_sharing string force
cursor_space_for_time boolean FALSE
open_cursors integer 300
session_cached_cursors integer 50
my update statement are following
Update jg_6july_dg0 Set Operator_code= '915724' where Operator_code= '015325';
Update jg_6july_dg0 Set Operator_code= '915715' where Operator_code= '015323';
.Update jg_6july_dg0 Set Operator_code= '915712' where Operator_code= '015374';
Cursor Caching I think is not a problem either it is a oracle bug or I’m doing something wrong. I can’t believe that oracle does not have solution for such little problem. My question is why oracle shutdown?? Waiting for you reply

sir no such error i got nothing. sir proces of rqasing SR is quite cumbersome. i'm stuck where SR first page ask Type of Problem it is hide how i set its value one more strange thing i have change the setting of SGA or PGA now the error in my alter log has been changed i have pasted here some part of alterlog plz check and told me what should i do now.

ORA-02103: PCC: inconsistent cursor cache

I have been hit by one error ORA-02103: PCC: inconsistent cursor cache (out-of-range cuc ref). it occur when user execute thousand of update statement in one go. I have place commit after 50 records. But problem is still there. It shutdown the oracle. I have to again startup oracle database. I’m running query from Toad. Server machine remotely connected with Toad using TNS. Why this error occur or plz guide what is the best way to update records. I have also used parallel Hint. Committing after 50 record reduce error occurrence but problem not solve completely

As per ora description:
Error: SQL 2103
Text: Inconsistent cursor cache (out-of-range CUC ref)
Cause: The precompiler generates a unit cursor entry (UCE) array. An element
in this array corresponds to an entry in the cursor cache (CUC). While
doing a consistency check on the cursor cache, SQLLIB found that the
UCE array contains an ordinal value that is either too large or less
than zero. This happens only if your program runs out of memory.
Action: Allocate more memory to your user session, then rerun the program. If
the error persists, call customer support for assistance.
How user is connected dedicated or shared? How much memory is used during update? Is it enough?
Is parameter open_cursors high enough?
And as You can see from error description - call Oracle support. Raise SR to Oracle - they will investigate and ask dump files and look through them and propose a solution.

Dual Processor Multi Core Parrell Processing Question

Hey Guys
I'm looking for a little clarification on an issue with parrell
processing in LabView. If I have a Dual Processor machine with two 4 core CPU's
will be able to access all 8 cores in the LabView environment. I'm presuming it
can use any cores the operating system can see?
Thanks for the help,
Tom
Solved!
Go to Solution.

it is the job of the OS that applications can use all cores if necessarry. So for the application itself, it should make no difference if the system (in hardware) is MultiCPU, MultiCore or even simply HyperThread.....
Norbert
Its true, but I would like to add my 5 cents here.
Lets say, if you have single loop like
while (true){
//do something
then OS will get no chance to run it in multiple threads. So, you will get max 12,5% CPU load at 8 cores PC or 50% max on dual core PC.
I have dual core PC right now, and lets check it:
So, as we can see - 50% CPU load reached (one core loaded more, but its another story).
Well, if we will use two while loops, then we will get 100 % load:
Of course, if you will need to load all 8 cores, then you should have 8 parallel loops.
Compare BD above with the following:
We have two Array minmax functions, and they independend, but we have 50% only.
Well, you can get also 100% CPU utulization withing single while loop. In th example below you have two SubVI, which called in the same loop:
We have here 100 %. Important, that these VIs should be reenterant!
See what happened if they not reeenterant:
Now a little bit about Vision. Behing of most of the Vision SubVIs are DLL calls. Some Vision functions already optimized for multicore execution. For example, convolution:
On the BD above we have single loop with one SubVI, but both cores are used (because convolute itself already optimized for multi core).
Remember, that not all Vision functions optimized yet. For, example, LowPass still single-threaded (compare this BD with BD above):
Sure, we can utilize multi cores - just perform parallel execution (you have to split image to two parts, then join together and so on):
Remember, that SubVIs should be reeentrant, and all DLL calls should be thred safe (not in UI thread). Also good idea to turn off debugging in such experiments for eliminate additional CPU load.
Another point about 8 cores. As far as I know, LabVIEW (and LabVIEW-based application) will support only 4 cores within one execution system by default (at least prior to LabVIEW 2009). If you need to utulize all 8 cores, then you should add some lines into LabVIEW.ini. Refer to the following thread where you can found more details:
Interpolate 1d slow on 8 core machine
Hope all written above was correct.
Thank for reading and best regards,
Andrey.

SQL-02103

This happend during a prepare for a select statement using embedded C (proc). The select statement had a length of 20. Here's more info about the error from the database:
out of memory (could not allocate)
inconsistent cursor cache (out-or_range CUC ref)
SQL-02103: Inconsistent cursor cache. Out of range cursor cache refere
Database: Oracle 10g version 10.1.0.3.0
OS: Redhat Enterprise ES version 3 update 4, linux 2.4.21-27
on a dual processor intel.
Can anyone tell me why this occurs and how I can fix it?
The machine had memory and swap space available.
Thanks,
Lamar

Cause: This internal error typically indicates a memory-related error.
Action: Check the program for memory-related errors, such as invalid pointers or array-bounds violations.

Compile c programs to use dual processors

I am trying to optimized a c program to run in a SunBlade 1000 with 2 processors.
gcc installed in the mchine is version 2.95.3.
If I want to compile the program to use both of the processors, how should I proceed? I read the gcc manual, also did some google searches, but did not get it to work.
I would appreciate your input very much.

The most straightforward way for this to happen would be if gcc had implemented openMP (which as far as I know, it has not). If you are set on using the GNU compilers, you'll have to create multiple threads to take advantage of the dual processors on your SB 1000. Describing how to write a multi-threaded app is considerably beyond the scope which could be addressed in this medium. You can start by reading up on multi-threaded programming and playing with the functions in libthread. Look at the man pages for thr_create and you'll find some simple examples to get you going. If you are open to using the Sun compilers Sun One Studio Compiler collection, the compiler can do some of the hard work for you. If you included openMP pragmas, it can do an even better job.

Error reading data from static cursor cache.

Hi,
Does anyone know what causes this error below. It just started happening out of the blue. I'm running Apache Tomcat 4.1 on Win 2000 server with MS SQL Server 2000 database.
Error:
java.sql.SQLException: [Microsoft][SQLServer JDBC Driver]Error reading data from static cursor cache.
Thanks,
TR

hi,
i had a similar sort of error, something along the lines of "error setting up static cursor cache" using the SQL JDBC drivers on Win2K. i deleted the file entries in the TEMP folder of c:\documents and settings\<user>\Local Settings\TEMP and everything was cool after it. i'm not sure what the exact issue is (probably something like maximum folder size had been reached). i ran the FileMon utility from www.sysinternals.com and it reported a DISK_FULL error on a temporary file being read by the process. to cut a long story short, everything is NOW cool.
cheer,

The SQL has aged out of the cursor cache.

Hi,
on 10g R2, Ihave the following :
The SQL has aged out of the cursor cache.
Does-it mean that undo_retention is not enough big?
For the moment it is 10800, 3 hours.
Thanks.

Hi,
The issue is that when in sql advisory I click on "Schedule SQL tunning advisor" it gives me "The SQL has aged out of the cursor cache".
If shared_pool is =0 , (automatic management) would it be usefull to define shared_pool_reserved_size value ?
In documentation it is said :
7.3.8.2 When SHARED_POOL_RESERVED_SIZE Is Too Small
The reserved pool is too small when the value for REQUEST_FAILURES is more than zero and increasing. To resolve this, increase the
value for the SHARED_POOL_RESERVED_SIZE and SHARED_POOL_SIZE accordingly. The settings you select for these parameters
depend on your system's SGA size constraints.
Increasing the value of SHARED_POOL_RESERVED_SIZE increases the amount of memory available on the reserved
list without having an effect on users who do not allocate memory from the reserved list.And actually I have REQUEST_FAILURES =15.
Thank you.

You can't use strongly types ref cursors with dynamic SQL, you will have to use weakly typed.

Cursor Invalidate error - ora-12842

Hi All,
A user is getting CURSOR INVALIDATE error on Select statement. Some times it works fine and some time it gives this error.
Can any one tell me is it some thing related to the database settings or the only reason is SQL coding. DB - 9.2.0.6
Thanks a lot..

This error is caused by an event outside of the user's session, such as DDL against the object(s) they're querying or somebody flushing the db cache. Hence the irregular pattern of occurrences. Is there anything in the alert log or a trace file which might help you with your troubleshooting?
Cheers, APC
