I dont know if it is a good thing i copy an init.ora file to initCHUCKY.ora and now database is using it I have just changed some values in it like control files dbname ... that were pointing to another database maybe this is why i dont manage to get this database runing.
Now i am stucked I dunno what to do

I made a tcpdump i saw the data is comong on localhost port 1521
Synthese I think the listener is runing, the database too, it is making a listen on 1521 port , when I try to connect data arrives on the right interface.
But I can't login by

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.

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.

(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,

The ORA-27101 error is generated when the shared memory key generated by the client does not match any currently existing keys. This is to be expected if the ORACLE_HOME or ORACLE_SID used by the client is not the same as that used when starting up the database.
Perform the following:
1) Check these environment variables and if required set them appropriately.
2) Review the listener.ora currently used to startup the listener and verify the ORACLE_HOME value is correct for all listed Oracle databases. If the ORACLE_HOME points to a different Oracle version then what was used when the database was created, then this error can occur.
3) Likewise, review the listener.ora currently used to startup the listener and verify the SID_NAME value is correct and has the right value (the SID_NAME is case sensitive).
Also check Metalink Doc ID: 167252.1 (ORA-27101: Shared Memory Realm Does Not Exist).

ORA-27101: shared memory realm does not exist - Oracle9i
I installed Oracle9i on Windows 2000 Professional OS. Before installing Oracle9i, I uninstalled 8.1.7 using the uninstall option in Oracle9i and cleaned up the registry entry as well. I uninstalled Oracle 8.1.7 ( product ) and not the database that was created and running on Oracle8.1.7. During my Oracle9i install I installed a new database. After the install was complete the new database connects fine, but the database that was created using 8.1.7 does not connect. My listener is running and the tnsnames.ora has the entry for both the databases. The services menu on Windows shows that the database is up and running. I am not able to connect to the database created by oracle8.1.7 using Oracle9i, using SQL*PLUS.
SQL*PLUS throws the following error message :
ERROR:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
I checked the trace files and oracle suggests me to open this database with migrate option.
Does anyone know the related command or where I can find a fix or documentation for this problem ?
All I am trying is to bring up a database that was created by a prior Oracle Version and I am not successful.
Thanks,
Nithy-Try below steps :
sqlplus /nolog
connect / as sysdba
select status from v$instance
I guess the instance/database is not open. -
ORA-27101: shared memory realm does not exist on Mac OS X
I know there have been quite a few postings on this topic already. However, my situation appears different since I am attempting to run Oracle 9i Developer Version R2 on a Mac with OS X 10.3.3.
After I create a database and try to connect to it using sqlplus, I see the error messages:
ORA-01034: ORACLE not available
ORA-27101: shared memory realm does not exist
Mac OS X Error: 2: No such file or directory
The database seems to be mounted correctly and the listener seems to be running.
I have followed the various advice on bouncing the database but nothing seems to help. Does anybody who may have experienced the same problem have any thoughts or suggestions?
It seems the problem has to do with my SID or hostname perhaps but I cannot figure out where the exact problem lies.
Any help is greatly appreciated.

Help with error:"ora-27101 shared memory realm does not exist"
Hello friends of the forum:
I would like to help me with a question imortante I am very new to this aspect of oracle:
And install Oracle 11g on win "view" and followed the steps in the installation of l at the start page www.oracle.com funcionava all fine, but after a month of any change:
The database does not start qe and get an error "ora-27101 shared memory realm does not exist".
At first and solved momentarily reboot oracle service ...... but after a while does not work but I can not conextar to leave the base because this errror ......
The database is a lapto instalao .... and I have 100gb of free space and 4 gb of memory do not understand why this happens .....
I have to do so you can have acces oracle based ...
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.

Thanksyour shareable memory area is not set for the oracle server. I think you install the server by using the command
# echo 500m > /proc/sys/kernel/shmmax
this command temporaryley increase the area not for permanent.
so edit the file which is /etc/sysctl.conf and change this parameter "kernel.shmmax=536870912" and then reboot your system and start the oracle.
If reboot is not an option the use this command to increase the required area.
#echo 536870912 > /proc/sys/kernel/shmmax
and then run the oracle. -

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:

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 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.

Is an iOS 8 update downloaded in iTunes for one device applicable to other devices?
I am updating to iOS 8 and have many iOS devices. If I download an update for one in iTunes, can I also use that download for the other devices or I have to download an update for each device? Thanks.
