I'm using Oracle 10.2.0 in windows 7.When i installed oralce it worked properly for 1 week, now throwing an error ora-01034 and ora-27101.
I just perform CRUD Operations with database as a java dev by connecting via MYEclipse, but it is not at all allowing me to connect.

I'm using Oracle 8i Enterprise Edition. When i try to connect my database using Internal user, i m getting messege "Shared Memory Realm Does Not Exist"
ORACLE was working perfectly on Windows 7 since Jan 2010. A couple of days ago I ran a procedure which was to update a table with 1000 columns. The procedure worked fine till it created a few thousand records and then it slowed down terribly. I closed the SQL Plus command line tool (CTRL C) and tried to restart and then tried to logon to get the following errors-
ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist
Then I used the Start Database tool (net start OracleTNSListener), but it showed "System 5 error". So after researching online I created Admin profile for WINDOWS 7 and logged in as an administrator. In the INIT.ORA file I increasd the SGA_TARGET to 5G and PGA to 3G. After doing that the above service is running but I'm still getting the ORA-01034 and ORA-27101.
Using cmd prompt in Windows and entering commands sqlplus -> Username: " / as sysdba" gives an insufficient privileges error.
i am continuously inserting data to oracle database after some time like 2 hours oracle disconnects,it creates erros like
ERROR: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist Process ID: 0 Session ID: 0 Serial number: 0
after restarting the database with shutdown immediate ans startup if i start inserting records it will show erros like
ORA-01653: unable to extend table SYSTEM.GLT_PROT_TRAFFIC_SUM_VOIP by 8192 in tablespace GLCOMM
but i have created the Tablespace with BigFile Auto Extend and max size unlimited, i am having 400GB disk space created Redo logs with 15gb,i have tried serveral times reinstalling the oracle but problem is not solved.
same problem is happenging with small datafiles also,
operating system: windows server 2008 R2 standard oracle server : 11g oracle client : 64 bit
Enter user-name: sys as sysdba Enter password: ERROR: ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist
Even i start the Oracle service through the services.msc there are no new entries seen in alert log file of the database.I even changed the init DBNAME. ora file but that file is not being read. what is the normal procedure used by oracle 8i while starting the DB ? Which file should be edited if i come across shared realm memory error.
When investigating memory usage on HP-UX V3 for my oracle database 11.2.0.3.4 which use AMM, it seems to me that system is not shifting shared SGA memory to private PGA memory when needed but it allocate other memory.The shared memory don't shrink all the memory_target id allocated. VSZ = RSZ
To test i have used this script which will allocate memory in process PGA.
create or replace package demo_pkg as type array is table of char(2000) index by binary_integer; g_data array; end;
[code]...
I have done the same test on a linux machine (Red Hat Enterprise Linux Server release 6.3) and the size of the POSIX shared memory switched (/dev/shm) to the PGA like demonstrated by Tanel Poder in his blog [URL]...
When i try to extract create statement of table i get below error message.

Note: ---- I am executing this command from another user 'DEMO' which has got DBA privilege.
how to fix this error and extract the create table statement.
I am seeing the following error message in alert.log (ORA-04031: unable to allocate 32 bytes of shared memory ) and my database goes into hung state and wont let any new sessions to connect and old sessions just hung with no response. i have to kill the instance to come out of this problem.
I am running 11.2.0.3 on AIX and have memory_target=35GB. I would like to know what approach to take to find out the root cause of this? btw - does AWR show if memory was under pressure and what SQL's were consuming more memory just before the problem surface?

Windows 2003 Server Enterprise Edition, Service Pack 2. 3.5GB RAM.Two Oracle Databases running on this server, one not heavily used. On the database i am concerned with it is 10.2.0.3.0.
I have just started to look at this database and am seeing various things in the alert log and have had user error messages as well.Initially when i started looking at this server it was running with quite a small SGA (600MB) and the memory_target_advice was saying to take it to 1000MB.(PGA is around 200MB)
In January, before i looked at it, it started to throw:
ORA-04031 unable to allocate 16 bytes of shared memory ("shared pool","........", "sql area", "tmp") These would occur regularly and mostly during nightly processes, it seems, and thus not bubbling up to users.Having switched the SGA_MAX_SIZE to 1GB a new set of errors starts to appear in the alert log:
ORA-27301: ..... Not enough storage is available to process this command ORA-27302: ..... ssthrddcr
At the same time the ORA-04031 errors start to bubble through to the users. Before i could return to the scene of the crime someone else set the SGA back to 600MB and the error messages stopped. However the ORA-04031 message start to reappear in the alert log. My questions are many and, mostly, from a lack of knowledge ;) In particular:
1. Why would increasing the SGA lead to a different memory error? I would assume this would have something to do with the amount of memory a 32bit OS will allow a single process to address but the PGA+SGA is only 1200MB.
2. How does a ORA-273xx error end up with a ORA-04031 being shown to the users? I would look at the listener log but its over 2GB!!!
IBM p series servers AIX 5.3 Server memory : 16G there are 2 instances on this server. 1. Near DR - 9840M 2. Test server - 1344M Rest is for server. Oracle 10.2.0.3.0 - Production
2 days ago we are running a stored procedure on this test server. After some time DB gave this error and stored procedure stopped.After that we were unable to login through Oracle Client Software. Whenever we try to login to this DB through client software, it gives following errors.
ERROR: ORA-01034: ORACLE not available ORA-27123: unable to attach to shared memory segment IBM AIX RISC System /6000 Error: 13: Permission denied
We tried to shut the DR database and then login but still gives error..
We had the following error in alertlog repeatedly from 5 PM to 10 PM :
ORA-04031: unable to allocate 32 bytes of shared memory ("shared pool","SELECT VERSION FROM PSVERSIO .....Since MEMORY_TARGET is defined in spfile then shared pool is managed automatically.
I have a package when it runs, it terminates with "unable to allocate 4120 bytes of shared memory"error at a particular INSERT statement. So everytime we had this error, we had to flush the shared pool area, after which it would run without issues(for 3-4 weeks).
It had a dynamic subpartition clause framed, which made it to repharse the query every time.So to reduce this, we removed the subpartition clause(made it to static query), which did benefit of not getting shared pool error.
I would like to find the current shared pool memory usage of my program.Is there a way I could find the live consumption of shared pool area of my program(pkg).
according to article "Installing Netbackup for Oracle agent on Unix". URL.... Shut Down all oracle instances on this client. The reason: sometimes Oracle will take a shared library (such as ours) and place it into its shared memory spaceMy question is how I can control existence shared library in memory space to define the real need of Shuting down of all oracle instances ? I'm usung 11.2.0.3
I scheduled a RMAN backup job to take FULL database backup to a shared network drive.
RMAN Script used:

Environment: Windows server 2003 OS and Oracle 10.2.0.4.0
Iam facing below error.

I checked shared network drive and found READ/WRITE access for me. I am able to take RMAN backup in local system without any issue.
we are trying ti implement BMC monitoring tool for our oracle 11g2 RAC/solaris10 environment. for the purpose we create a user called bmcuser in OS level, this user connecting database to monitor, this user occupy shared memory as oracle. Explain why this user taking that much shared memory just to connect database using sqlplus.

from what I read I beleive this will initially grab 2GB of memory on startup and will grab up to to 3GB of memory total for the SGA. The "total" memory can be allocated to different peices of the SGA when needed but will never exceed 3GB. Is this correct or would these settings infringe on any available memory on a system that is already tight on memory?
Secondly, what happens if both these values are set to the same value?
Can i know the internal process of initialization of DB into memory in timesten , when a new connection is establishing? Will timesten create tables and indexes in RAM when first connection is established if the RAM policy is default?
want to know the internal functional flow of timesten when any command is fired against it.
