I cant able to connect to my local DB instance. Oracle service for DB instance will be started running when the system boots automatically.I faced this problem before, I was instructed to boot my system without network connection. It worked for few days. Suddenly I cant able to connect to my local DB instance again, even though I am booting my system without network connection.
This is the configuration I have in tnsnames.ora in my local machine.I have the host as localhost, because local machine is laptop and IP will change periodically.
Is it possible, Oracle let me connect to an running +ASM instance from a different host? I.E, +ASM running on X host and i want to connect from Y host. (yes Y host has the asm entry in the tnsnames.ora).
I have installed oracle 10g database in the my local laptop ( Windows 7) . This laptop is in LAN. I am not able to connect from other machines in LAN. When i open sqlplus, SQL Developer from the same machine, i was able to login to the instance.
But when i want to login from the other machines in LAN. I was not able to connect. I was able to ping the server on which the database was installed from other machines. why i am not able to connect ?
1) I put attention that TNS write events into its log in too big frequency: ~ 10 time in second. I see that it is for every connection, but I assume that this no too good to performance.Is there some way to tell to TNS not to write event for every connection but only for errors?
2) May I to remove alert.log of DB? Or DB will make me problems with this?
3) How can I tell to my client connect directly to my instance rather than during TNS?
I have Oracle RAC 11g running on Red Hat 4 64 bit.
when i configure monitor target in GC12C,1 find i can not add asm instance target, and i use scan ip in 11GR2 rac ( two nodes )the problem is plublic IP's 1521 port not accept connect request from remote IP
error from gc12c Failed to connect to the ASM: IO Error: The Network Adapter could not establish the connection The Connect Descriptor was (DESCRIPTION=(ADDRESS_LIST = (ADDRESS=(PROTOCOL=tcp)(HOST=172.20.101.78)(PORT=1521)))(CONNECT_DATA=(SERVICE_NAME=+ASM1)(INSTANCE_NAME=+ASM1)(UR=A)(SERVER=DEDICATED))) [code]....
how can i let GC12C see ASM instance on each node in cluster??
Acer laptop, Intel Processor w/ Windows 7 Professional (64-bit) Delphi 2010 Professional Oracle XE (+ the Oracle XE client that comes with it)
I cannot can't to the Oracle database from Delphi. The error I keep getting is:
Alias is not currently opened. [Oracle][ODBC][Ora]ORA-12154:TNS: could not resolve the connet identifier specified.
Here's what I've done:
1. Create an ODBC connection to my Oracle database
- run C:WindowsSysWOW64odbcad32.exe to open the ODBC administrator. - Data source name: bt_user - TNS Server Name: localhost/xe - user bt_user - Clicked "test connection" -- Success.
2. Open Delphi and drop a TDatabase component on my main form.
- Set the Alias Name property to "bt_user" (the alias I set up in ODBC) - Set database name to "bt_user". - Checked "connected".
Alternatively, I tried using the Delphi ADO components (the dbGo components).
- Drop TADOConnection component on my form. - Select "connection string" and open the dialog. - Click "build string". - Select "Microsoft OLE DB Provider for ODBC Drivers" from the selection. - In "use data source", select "bt_user" from the drop-down list (my ODBC connection from #1) - Click "test connection".
Again the same error.
My questions are:
1. Can Delphi work with Oracle XE (Express Edition)?
2. If so, then do I need to install the "Instant Client"?
3. Will the instant client for Oracle 10g work with Oracle 10g XE?
4. Do I need to install any additional ODBC driver(s)?
5. Why was I successful in creating the ODBC connection in Windows, but it failed in Delphi?
6. Will Visual Studio.NET (C#) work with Oracle XE, and what are the steps for setting that up?

In every oracle documentation for e.g:11.2 Scan and Node TNS Listener Setup Examples [ID 1070607.1] we found the local listener status showing both local-ip and vip. Why is not showing in our case?
I tried to clone a 2 node rac database to single instance non rac database using existing backup. I have not used connectivity to target or catalog. rman duplicate finished with below messages:
rman auxiliary sys/******@dbracdup RMAN> duplicate database to dbrac spfile backup location '/oracle/backup'; ... ... Finished recover at 25-JUL-12 Segmentation fault
And the database was in mount stage, and when i tried to open database it failed with below error:
SQL> alter database open; alter database open * ERROR at line 1: ORA-19838: Cannot use this control file to open database .
I want a copy of data from oracle database in Production to my local machine as upgrade is going to be there soon. How can I do that so that I may check my old data later irrespective of upgrade?
- one ASM instance - X DB instances - each DB instance uses 2 or more dedicated diskgroups from the ASM instance - there is one diskgroup named FREEDISK that contains spare disks
On each DB instance you can see:
- the list and global parameters of all diskgroups using v$asm_diskgroup view - the list and parameters of all disks the instance is using with v$asm_disk view
So my question is: how (if this is possible) to know the list of (spare) disks in FREE DISK disk group?
My database is working on Oracle 10g. After installing a Oracle 11g in my PC instance went down and my database got corrupt. What are the steps I should follow to recover my Database?
I've checked ALL the parameters. It seems to be OK.The db is running and OK.But when I try to configure the EM I get the following error Says that the databse instance is not available.But, tnsping works ok, and I can connect as sys without problems. the DB is OK.

suggest on the dependenecy between the database service and the database instance?
srvctl start instance -i db1 will this start service as well for which the above instance is either preferred or available instance? will it start the listener as well?
srvctl stop instance -i db1 will this stop service as well for which the above instance is either preferred or available instance? will it stop the listener as well?
srvctl start service -d db -s dbserve will this start service as well for which the above instance is either preferred or available instance?
srvctl stop servive -d db -s dbserve will this stop service as well for which the above instance is either preferred or available instance?
srvctl start database -d db will it start instance, listener and service as well?
srvctl stop database -d db will it stop instance, listener and service as well?
I am running ORACLE 10.2.0 on Windows Virtual PC. System: Microsoft Windows XP SP3.
Yesterday I wanted to make a copy of my Virtual Machine Hard Drive Image. I directly copied all the files to my external hard drive, but I forgot shutting down my virtual machine when I was doing this.
Today I found my instance failed startup.
In OEM, it is showing:
Agent Connection to Instance Status: Failed Details ORA-12505: TNS:listener does not currently know of SID given in connect descriptor (DBD ERROR: OCIServerAttach)
In SQLPlus:
SQL> connect sys/password as sysdba Connected to an idle instance SQL> startup ORACLE instance started.
We are planning to consolidate our Oracle Production DB into one server. We are basically a windows shop. Is it feasible to run 8 production Oracle DB in one windows server. All the DB are not really transaction intensive DB. 2 DB in the size of 300GB and others all DB falls under average size of 40GB.
I can take care of the HD slicing so Oracle does not enter into IO bottleneck. We are planning to go for external NAS or SAN for storage.
My main concern is on processor usage. The processor we are thinking about is Intel Xeon Quad Core x 2nos. Will there be a processor bottleneck or is there way in Oracle to assign processor usage(I belive there is no much tweaking options here)
I want to install oracle 11.2.0.2 single instance database on AIX 6.1, does oracle recommend separate OS user for grid infrastructure and for oracle install? how many groups I need to have for these users like oinstall, dba etc?
I have an issue with restoring a RMAN backup that i have with me to a new database instance. What i have with me are: 1. Backup of SPFile.
(O1_MF_NCNNF_CTLFILE_BU_92DVGYO2_.BKP)2. Backup of Control file (O1_MF_NNSNF_SPFILE_BU_92DVGW9H_.BKP)3. Full database backup (O1_MF_NNSNF_FULLPROD_BU_92DVGW9H_.BKP)
I have received these files from a customer environment and I need to restore these to a new database instance in a local machine. I have given a attempt as follows (in Oracle 10g): 1, Created a new database instance (Test75) using Oracle Database Configuration Assistant2. SET ORACLE_SID = Test753. Connected to this instance using RMAN4. Tried to restore the SPFILE from the received BKP file.I am getting errors and cannot proceed. I am not sure whether I am executing the correct steps.
I would like to use Oracle Grid Infrastructure to protect a single-instance database.
I found these docs:
[URL]
I was unable to find a similar document for GI 11.2 . Do you know if such a document exists?
At the moment I only know that the GI is free if used for an Oracle Product, but I am not shure whether it can be used to protext external applications or single-instance databases
