"shared memory realm" error -- cross-posted in "installation"
I've just installed 8.1.7 on a Solaris 8 workstation. The installation went fine up until the database creation assistant tried to create a database: it failed. But the software was all installed, so I did a "connect internal" and created a database myself. Once I start the database, I can connect as system/manager; but when the database is shutdown, connecting as system manager gives me an "Oracle not available" error (ORA-01034) followed by a "shared memory realm not available" error (ORA-27101) followed by a "no such file or directory" error (SVR4 Error: 2:).
All of the shared memory and semaphore parameters are specified in the /etc/system file, and they show up when I execute a "sysdef -i" command.
Any ideas why I'm getting these errors?
I did a search and found a few posts on "shared memory realm," but none of them seemed to address the fact that I can connect when the database is started/mounted, but not when it's shutdown.
Thanks in advance,
Rich
make sure the env var ORACLE_SID is set.
check PROCESSES in your init.ora file. if you lower this number (to say, 15) and errors go away then you need to up the semiphores kernel parameter (or leave PROCESSES set to a low number). Also, it is correct to get an error when trying to connect to a database that is shutdown. the only way to not get an error is use svrmgrl or "sqlplus /nolog" and then connect / as sysdba (or connect internal).

Help! 2701 shared memory realm error
When I try to run the import command I get a shared memory realm error. I've checked my $ORACLE_SID with my /etc/oratab file they both match up fine. The initSID file is also correct, with the correct case. "lsnrctl start" seems to start correctly with no errors either on the screen or in the log file. --I'm confused....
ORACLE_SID=sidname
export ORACLE_SID
ORACLE_HOME=/...

oratab is the unuseful file -

i have installed the oracle 8i correctly on a windows 2000 server p4 machine
(i ommited the symcjit.dll file after copying the source to the hard disk and installing from there) ...
after the installation is succefully ended and i connected to the database using the sqilplus , i have created a new user and imported a table of 100 mb , then i restared
after that when ever i try to connect in the sqlplus it says (shared memory realm error!!)
i do not know wat does that means ,,
but i have a virtual memory file (from 380 up to 600mb) on the c: drive and i created another virtual memory on the d: drive (from 300 to 400mb)
can anyone help me with that?Thanks for help.
well it is so good what you have said .
BUT
i do use windows 2000 server ,,
i do not know where do i issue these commands ..? (in the dos command prompt? or under the sqlplus prompt?!)
sorry if my quistion appear to be silly , but i really do not know where do i write these commands ..
and pleasue do i need to issue these commands every time i restart windows or just one time?(and if i need to write them each time , is there somthing i can do to keep the oracle engine from shutting down? "i.e restart automatically"?)

ERROR - ORA-01034: shared memory realm does not exist
Hallo!I am a newbie in Oracle in Linux.I have just installed Oracle 10g in Oracle Eenterprise Linux version 4 Update 7.The installation was successful and I could
work with sqlplus,isqlplus and Enterprise Manager.When I restarted my machine,I manually started the listener,OEM and isqlplus which started successfully.
However,when I try to log into OEM and isqlplus,the error message below appears
ERROR - ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist Linux Error: 2: No such file or directory
How do I resolve this?
Thanks.4joey1 wrote:

ERROR - ORA-01034: ORACLE not available ORA-27101: shared memory realm does not exist Linux Error: 2: No such file or directory An Oracle instance consists of a number of Oracle server processes (the limbs) and a shared memory area (the brain). Each and every server process participating in that Oracle instance needs to attach to the shared memory area.
The error message you see, states that the server process (launched in order to service your sqlplus/OEM client), failed to find and attach to this shared memory segment.
Two basic reasons for the failure.
The Oracle instance is not running. There are no shared memory area and Oracle server processes running for that instance. Solution: start up the database instance.
The server process was launched with the incorrect parameters (ORACLE_SID specifically) and attempted to attach to shared memory that does not exist. Solution: review the TNS/JDBC parameters of the client connection and configuration of the Oracle Listener to ensure that a server process launched to service a client, does so with the correct parameters and environment. -

I can help with this problem .... thanks ....
I like to see that show me with pictures as I am new in this aspect of oracle .... and want to learn it .... thank you very muchHello friend..
The error you are getting *"ORA-27101: shared memory realm does not exist"* may be coz you are trying to connect to your database which is already shutdown not as sysdba user but as some other user, becoz of which you are getting this error. It sometimes happen that the service of the database is already started but when you try to connect to a shutdown database as users other then sys even having the DBA priviledges you cannot connect to database.
Try to connect as SYS user hope your problem will be resolved.

regardsHi,
>>do you recommend using auto undo_management instead of RBS?
Yes. To simplify management of rollback segments, the Oracle9i database introduced Automatic Undo Management (AUM) where the database automatically manages allocation and management of undo (rollback) space among various active sessions. In a database using AUM, all transactions share a single undo tablespace. Any executing transaction can consume free space in this tablespace. Undo space is dynamically transferred from committed transactions to executing transactions in the event of space scarcity in the undo tablespace..The AUM feature also provides a way for administrators to exert control on undo retention. You can specify the amount of undo to be retained in terms of wall clock time (number of seconds). With retention control, you can configure your systems to allow long running queries to execute successfully without encountering ORA-1555 (Snapshot too old) errors ...
For more information, you can take a look on these links below:

Oracle not Available, Shared Memory realm doesn't exist
Hi,
I have problem during XE installation on Windows 2003 R2 SP 2 Enterprise edition. I have uninstall the oracle xe and the result still the same. Finally I uninstall the windows and start all over again, surprisingly the result still the same. FYI, we normally has no issue during installation because this is part of our system we sell to our customer which require oracle xe. This is the first time we have seen this issue.
ORA-01034 : Oracle Not available
ORA-27101 : Shared memory realm doesn't exist.
Oracle XE and listener services is started in the windows services.
if we try to do startup the following message occured.
SQL> connect /as sysdba
Connected to an idle instance.
SQL> startup
ORA-44412: XE edition memory parameter invalid or not specified
SQL>
I can send you the oracle_xe log, init ora, and OpsBuildAll.log to create the database.
When we compare with the working installation, we saw that the size of oraclexe folder is less, it's just 233MB while the working one is over 1GB. After investigation, found out that the .dbf files is not avaiable in the oradata folder, i have tried to copy those files from the working one but the problem stay the same, probably there are a lot of files more missing.
Appreciate your help on this.
Thanks,

I dunno what is this fuckin shared memoryThis fuckin shared memory is how oracle does interprocess communication. When you connect to Oracle, you have to connect to this area. If you tell it the wrong area, it won't find it. You can see the areas with the ipcs command on the server. Since you can connect locally, but can't connect remotely, there is something wrong with how you told Oracle to connect remotely. Remotely can be on the same host if you have an @ in the connect string.
>
env | grep ORACLE
ORACLE_SID=CHUCKY
ORACLE_BASE=/home/oracle
ORACLE_HOME=/home/oracle/u01/app/oracle/oracle/product/10.2.0/db_1/
seems like my variables are good.
Well I dunno what to do I didn't think getting a simple login locally over tcp/ip would be so difficult, I am afraid of what will happen after this will work :) As it should be one of the easiest things on oracle what about the hardest :)Well, first try removing the trailing slash from ORACLE_HOME everywhere, including if you have it in the listener.ora. Then compare the tnsnames.ora ORACLE_HOME with your environment ORACLE_HOME. In fact, if you have a listener.ora, try renaming it to something else and restarting the listener.
That error is normally due to a bad ORACLE_HOME or ORACLE_SID. Since your tnsping works, that indicates the ORACLE_HOME is good. But all that tells you is that the listener responds. Other causes may be inadequate processes in init.ora or case issues with the sid, or just generally not following the installation instructions. But are there installation instructions for debian?
With multiple databases on one host, some kernel parameters may need to be increased. -
(HELP) ORA-27101: shared memory realm does not exist
Contributors,
I am a newbie in Oracle and have oracle database installed and working as expected until few days ago. One day i was getting these ugly messages when connecting via SQLplus
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Process ID: 0
Session ID: 0 Serial number: 0I did some searches on this topic but haven't found solutions.
* Some suggested to check[b] environment variables ORACLE_HOME and ORACLE_SID : my ORACLE_HOME is fine, and i DO NOT have ORACLE_SID on the day i realize the problem.
I am not sure if ORACLE_SID variable is usually exist when my database was up and running. So i set ORACLE_SID yet did not help.
* Some said check if the required services are running :
- OracleOraDb11g_home1TNSListener : RUNNING
- OracleServiceORCL : RUNNING
* Other said that they have the same problem, but everything back to normal after several hours without anything configured / changed (miraculous)
* I tried to restart or shut down, but no luck
* In the same thread few days ago, Vlado helped me with suggestion to acces ADRCI and type SHOW PROBLEM also SHOW INCIDENT
but the reply is DIA-48494: ADR home is not set, the corresponding operation cannot be done* Other implied to check the .ora files in NETWORK\ADMIN. I will post it (TNSNAMES.ORA, LISTENER.ORA, SQLNET.ORA) after this.
My platform and some info :
* OS : MS Windows Vista Ultimate
* Oracle Database 11g Release 1 (11.1.0.6.0) Enterprise/ Standard Edition for Microsoft Windows 32-bit
Mostly i used SQLplus and SQLdeveloper, for developing procedures/ functions/ packages in Oracle Spatial.
Also, am running it in one laptop (server and client altogether).
There is only one database in the Laptop (no other oracle database).
How to fix this ? Please kindly help me.
Many thanks in advance,
DamonHere are the ORA files :
( Btw the service name / SID is "orcl")

ORA-27101: shared memory realm does not exist - Please help!!!!!
OS : Win 2000 server
After good installation, when I want to connect instance ORCL by using SQLPLUS worksheet (as system/manager), I got this 2 error messages :
ORA - 01034 : Oracle not available
ORA - 27101 : shared memory realm does not exist
In regedit: Ora_home = "my true path to Orahome directory

Thank you for help !!!!!!Can you connect using plain SQL*Plus (sqlplus.exe)? Your database may not be started, try this:
c:\sqlplus /nolog
SQL>connect / as sysdba
SQL>startup
Then try connecting as one of the default users:
SQL>connect scott/tiger -

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

ORA-01031: insufficient privileges and shared memory realm does not exist
Hi all,
I came to a dead end to start oracle 10.2 database. I have searched on google and this forum, none of these solutions work for me. PS, I have installed 11g on my machine too.
I have set up ORACLE_SID,ORACLE_HOME to 10.2 database based on the tnsnames.ora.
follow is error message:
