How to modify or change some parameter for fix this problem?

I think you need to give more description about problem.
You might review the following Oracle Metalink Document:
SQL*Net (oracle Networking) Common Errors & Diagnostic Worksheet: Doc ID: Note:45878.1
https://metalink.oracle.com/metalink/plsql/f?p=130:14:5712140308577577466::::p14_database_id,p14_docid,p14_show_header,p14_show_help,p14_black_frame,p14_font:NOT,45878.1,1,0,1,helvetica
If possible also upgrade your database.

ORA-12500 and sort_area_size value

Hi,
I've hit an ORA-12500 'listener failed to start a dedicated server process' error after the increase of sort_area_size from 250M to 500M. DB server has plenty of RAM which would easily accomodate additinal memory for PGA. Has anyone experinced that before? Thanks.

There's (normally) no need to set SORT_AREA_SIZE, when a PGA is configured. From the parameter reference:
Oracle does not recommend using the SORT_AREA_SIZE parameter unless the instance is configured with the shared server option. Oracle recommends that you enable automatic sizing of SQL working areas by setting PGA_AGGREGATE_TARGET instead. SORT_AREA_SIZE is retained for backward compatibility.

ORA-4030 and memory usage by oracle

I'm looking this documento on metalink:
Note:233869.1
Diagnosing and Resolving ORA-4030 errors
II want to know which process is requesting too much memory.
The document says:
On Microsoft windows systems, oracle is implemented by using threads in a single oracle process. Up to now, i didn't find a way to view the memory usage per thread. We can however check if oracle and the operating system agree on the memory used by oracle.
For the Operating system point of view, we can use task manager. Use the view pusbutton and select Select Columns... make sure Virtual Memory Size is selected.
And in my system is: 1.716.712 K
Then I execute this select to get the memory size as viewed by oracle, however, not including the process stack and code size:
select sum(bytes)/1024/1024 Mb from
(select bytes from v$sgastat
union
select value bytes from
v$sesstat s,
v$statname n
where
n.STATISTIC# = s.STATISTIC# and
n.name = 'session pga memory'
MB
5711,88542
How can it possible? 5G!

Hi,
It may be from the Paging space of your SYSTEM.
If you want to know in detail.
select details from the v$sesstat and get the session wise PGA allocated.
I also did not understood the statement "And in my system is: 1.716.712 K"

ORA-12500 problem, ¿can be?

We investigate all the facts that can provoke ORA-12500 and we are not allowed to connect to the database, the database is running, the service is running, the memory is OK , they are not too many connections because the database is just connected, and we are at this time allowed to connect to the database.
Then i have this question , maybe can the database be corrupt?
¿Someone have this problem after us?
Thanks at advance, Joan

Nio ByteBuffer and memory-mapped file size limitation

I have a question/issue regarding ByteBuffer and memory-mapped file size limitations. I recently started using NIO FileChannels and ByteBuffers to store and process buffers of binary data. Until now, the maximum individual ByteBuffer/memory-mapped file size I have needed to process was around 80MB.
However, I need to now begin processing larger buffers of binary data from a new source. Initial testing with buffer sizes above 100MB result in IOExceptions (java.lang.OutOfMemoryError: Map failed).
I am using 32bit Windows XP; 2GB of memory (typically 1.3 to 1.5GB free); Java version 1.6.0_03; with -Xmx set to 1280m. Decreasing the Java heap max size down 768m does result in the ability to memory map larger buffers to files, but never bigger than roughly 500MB. However, the application that uses this code contains other components that require the -xMx option to be set to 1280.
The following simple code segment executed by itself will produce the IOException for me when executed using -Xmx1280m. If I use -Xmx768m, I can increase the buffer size up to around 300MB, but never to a size that I would think I could map.
try
String mapFile = "C:/temp/" + UUID.randomUUID().toString() + ".tmp";
FileChannel rwChan = new RandomAccessFile( mapFile, "rw").getChannel();
ByteBuffer byteBuffer = rwChan.map( FileChannel.MapMode.READ_WRITE,
0, 100000000 );
rwChan.close();
catch( Exception e )
e.printStackTrace();
I am hoping that someone can shed some light on the factors that affect the amount of data that may be memory mapped to/in a file at one time. I have investigated this for some time now and based on my understanding of how memory mapped files are supposed to work, I would think that I could map ByteBuffers to files larger than 500MB. I believe that address space plays a role, but I admittedly am no OS address space expert.
Thanks in advance for any input.

Hi
We mostly receive this error message ( ORA-27101: shared memory realm does not exist and ORA-01139)
When our SGA_MAX_SIZE is greater than 1.7 G.b on
You again configure your sga size
and sga_max_size paramete will not greater than 1.7 G.b
Hope your database will work correctly.
for test purpose you set all your init.ora parameter
db_cache_size=512m
db_keep_cache_size=64m
db_recycle_cache_size=16m
java_pool_size=8m
large_pool_size=16m

sga_max_size will not be grater than combination of of db_cache_size db_keep_cache_size,db_recycle_cache_sizejava_pool_size+share_pool_size+share_pool_reserved_size
Hope it will work fine.

Oracle 9i ORA-12500 WIndows XP Pro

One embarrased Oracle DBA. I've successfully installed Oracle on so many windows platforms that I've lost track.
The specs:
Dell Inspiron 5100
Windows XP Professional 2002 SP 1
2.66 GHz P4 CPU
512 MB RAM
1 GB Pagefile (swap)
Macafee Virus Protection (disabled)
Macaffee Firewall (disabled)
XP Firewall disabled in communication settings
Oracle 9i Release 2 EE base release
Processes = 150
Sessions = 170
shared_pool_size = 50 MB (tried setting as high as 150 MB)
I've tried every trick in the book
1. Clean de-install, reinstall
2. listener start with and without listener.ora
3. Enabling and disabling MTS (shared server)
4. LAN connection enabled (w/ appropriate parameters)
5. Standalone mode (no networking) w/ appropriate parameters
5. Increasing init.ora parms for memory, processes and sessions to ridiculous levels
6. Different listener ports other than 1521
7. deleting and recreating listener service
8. deleting and recreating Oracle service (oradim)
9. setting USE_SHARED_SOCKET in Oracle registry (in case the firewall was interfering with listener ports)
10. setting TNS_ADMIN (not relevant since there is only one Oracle Home
11. made sure ORACLE_SID was set in Oracle registry
12. setting ORACLE_SID and ORACLE_HOME at the command line and restarting listener/database in command window
13. Turning on listner and client tracing to admin level
14. ad infinitem
Tracing didn't reveal anything meaningful. I was able to briefly get a connection working (connecting on the laptop via SQL*NET to the local database) using MTS for about 3 minutes then it started malfunctioning again.

I configured my Notebook with a Dual-boot Windowx XP Pro SP3 and Windows Vista Bussines SP1 (32 bit)
I have 2x 512 MB PC2-5300 667 MHz DDR2 memory inside.
I read on the Lenovo site :
Memory Compatibility

I like to update my memory with
2x 40Y7734 1 GB PC2-5300 667 MHz DDR2
or
2x 40Y7735 2 GB PC2-5300 667 MHz DDR2
I like to know if I choose for 2x 2GB , will :
Windows XP SP3 work just fine only it works with 3GB instead of 4GB installed memory
Window Vista SP1 (32-bit) with the 4GB (even not supported) work stable ?
Because the prices of 1 GB and 2 GB won't change much nowadays.
I prefer to use 2x 2GB modules, but I like to know will it work (even with the memory limitation) stable on XP or on Vista
or it is better/safer to use 2x 1GB modules
Can anybody help/explain me or advice me ?

You're better off with 2x2GB, you may decide to run a 64-bit OS someday...and you will notice a difference between 2GB and 3GB when running a 32-bit OS.

What is the difference between Azure RemoteApp Basic vs Standard Plans in terms of compute cores and memory?

So our customer has asked us to compare compare Amazon Workspace and Azure RemoteApp offerings for them to choose from. While looking at Amazon Workspace, it clealy defines bundles with specific CPU cores, memory and user storage. However, Azure RemoteApp
only specifies user storage and vaguely compares its basic vs. standard plans in terms of "task worker" vs. "information worker"
I tried looking up its documentation but couldn't find specific CPU cores that are dedicated per user in basic vs. standard plans. I have following questions:
Can anyone point me in the right direction or help understand how many CPU cores and memory are dedicated (or shared) per user in each plan?
Our customer would most likely need a "custom" image for their custom apps. Is it possible for us to choose specific CPU cores and memory for the users to be able to run their apps in azure remoteapp?
In case i am misunderstanding the basic difference between AWS workspace and Azure RemoteApp, i'd appreciate some help in understanding it as well.
Thanks!

Hi,
With Azure RemoteApp users see just the applications themselves, and the applications appear to be running on their local machine similar to other programs. With Workspaces users connect to a full desktop and launch applications within that.
1. Azure RemoteApp currently uses size A3 Virtual Machines, which have 4 vCPUs and 7GB RAM. Under Basic each VM can have a maximum of 16 users using it whereas under Standard each VM is limited to 10 users. The amount of CPU available
to a user depends on what the current demands are on the CPU at that moment from other users and system processes that may be on the server.
For example, say a user is logged on to a VM with 3 other users and the other users are idle (not consuming any CPU). At that moment the user could use all 4 vCPUs if a program they are running needed to. If a few moments later
the other 3 users all needed lots of CPU as well, then the first user would only have approximately 1 vCPU for their use. The process is dynamic and seeks to give each user their fair share of available CPU when there are multiple users demanding CPU.
Under the Standard plan a user will receive approximately a minimum of .4 vCPU assuming that the VM has the maximum number of users logged on and that all users are using as much CPU as possible at a given moment. Under the Basic plan the approximate
minimum would be .25 vCPU.
2. You cannot choose the specific number of cores and memory. What you can do is choose the Azure RemoteApp billing plan, which affects the user density of each VM as described above. If you need a lower density than Standard you
may contact support.

Memory_target and memory usage reported by windows taskmanager

Hi,
shouldn't Oracle 11g limit the amount of used memory (reported by windows taskmanager for process oracle.exe) to the value of "memory_target" (which means using automatic memory management)? My database running on Windows 2003 R2 32bit (RAC) is constantly consuming more and more memory (limited to 500MB, currently using 741MB), until it reaches the limit of 1.7GB, which one process can use. After this the database fails.
The database is hosting three very simple applications, no challenge for Oracle. :-)
Thanks in advance,
Frank

short update: both database instances are configured for 500MB "memory_target" and currently one database is using 877MB virtual memory and the other one 784MB of virtual memory (according to windows taskmanager, process oracle.exe). One of these instances is a recovery catalog, doing nothing at all (at the moment).
I'm really worried where all the memory is going to!

HDD and memory upgrade on Satellite A350

Hi All
I have a satellite a350 laptop can anyone tell me whats the biggest harddrive I can have and memory please
Thanks

Hi
The RAM upgrade depends on the available chipset.
Not quite sure about your A350-xxx model but many of the Sat A350 notebooks were quipped with an Intel GM45 Express chipset and in such case you could upgrade the memory max up to 8GB RAM
Regarding the HDD: This notebook supports SATA HDD. This mean that you are not limited to an special size.
Theoretically it could be possible to use 500GB, 750GB 2.5 SATA HDDs

Memory limitation for session object!

what is the memory limitation for using session objects?

as already mentioned there is no actual memory limitation within the specification, it only depends on the jvm's settings
how different app-server handle memory management of session objects is another part of the puzzle, but in general you should not have problems in writting any object to the session.
we had the requirement once to keep big objects in session, we decided to do a ResourceFactory that returns us the objects, and only store unique-Ids into the session.
We could lateron build on this and perform special serialization tasks of big objects in the distributed environment.

Hi Wim
You should say that "It may be Control File problem", but you shouldn't say that "it's due to Control File" problem
Please refer to Errors Documentation for more information on ORA-00600
http://download.oracle.com/docs/cd/B19306_01/server.102/b14219/e0.htm#sthref371
ORA-00600: internal error code, arguments: [string], [string], [string], [string], [string], [string], [string], [string]
Cause: This is the generic internal error number for Oracle program exceptions. This indicates that a process has encountered an exceptional condition.
Action: Report as a bug - the first argument is the internal error number
