Not only will parsing a statement like that (also called a HARD parse) consume many more resources and time then reusing an already parsed query plan found in the shared pool References forbidden References suffer from the same problem as pointers (mainly because they are implemented as pointers). http://ipodcorrectors.com/shared-memory/shared-memory-server-side-error-x11-error.php
the default is 8m on 32bit, 64m on 64bit -- check it out. this occurs in 126.96.36.199. or B) Keep some objects in reserved area or C) Reduce the size of Share pool reserve area to 0. it is because people are using it and on production you have lots of people.
Sqlceexception Internal Error Cannot Open The Shared Memory Region
Thanx! Actually I posted this problem in the same thread (June 12).. ORA-7318 Oracle could not open the sgadef file. Is there any work around ?
- The class represents a memory region that has been mapped from a shared memory or from other devices that have also mapping capabilities (for example, files).
- Take in care that if the server exits before the client connects to the shared memory the client connection will fail, because the shared memory segment is destroyed when no processes
- This error may indicate Windows resource prob lems.
- This increases your performance and greatly increases your scalability.
- But to me this look quite strange.

- It was shared pool latch contention due to literal/unshared SQL.
- Remember that Oracle rounds its calculation of SHMMAX to a page boundary, so it may have rounded it up past the real SHMMAX! (Whether this is a bug is

This is far too small in most cases. Anyone considering using the services of an Oracle support expert should independently investigate their credentials and experience, and not rely on advertisements and self-proclaimed expertise. bind variables, bind variables, its all about bind variables. The system error should be reported.

Look at the nattch column: are there segments with no processes attached that were not removed when processes exited (which normally means the program crashed)? Static members are not dangerous if they are just constant variables initialized when the process starts, but they don't change at all (for example, when used like enums) and their value August 20, 2003 - 9:43 am UTC Reviewer: A reader But Tom, Why is this not occuring in case of PACK3 in the above person's case. We run a query ("SELECT * WHERE ROWNUM <=1" or something like this) from each of the tables automatically a number of times in our scheduler process.

This would never happen on startup; it only would happen on connects. It doesn't hurt to set SHMALL and SHMMAX to values that are higher than the available amount of memory.

Executing SQL statements without bind variables is very much the same thing as compiling a subroutine before each and every call.

I did not do anything specific to have those shared server connections (unless our applications middle tier connection pooling has anything to do with it - I dont think so!). cache hit ratios are not meaningful in themselves (see hotsos.com and get "are you still using cache hit ratios") If you want your cache hit ratio to go waaaayyy up -

Boost.Interprocess offers a smart pointer called boost::interprocess::offset_ptr that can be safely placed in shared memory and that can be used to point to another object placed
If you like Oracle tuning, you may enjoy my new book "Oracle Tuning: The Definitive Reference", over 900 pages of BC's favorite tuning tips & scripts. How to fix it? IF you are in fact hitting this, there are patches for 9204, 9203 as well. Or is there any alternative for this.
We've got ~2000 short-lived tables created dynamically with unique names for every one of our ETL load processes (imagine 2-3x a day--6000 or so queries of the form below a day).
