spfile is created in folder DB_UNKNOWN

Using Linux RH4 64Bit with Oracle 10.2.0.3 with OMF on ASM
when we tried to "create spfile from pfile;" the spfile was located in a wrong location:

+DATA1/DB_UNKNOWN/PARAMETERFILE/SPFILE.185.634235343
The link was pointing to the right location.

After some struggles we found the solution in Note: 393932.1
We even managed to fix it by the note instructions:

1. Create a pfile
   SQL> create pfile='/tmp/pfile' from spfile'+DATA/DB_UNKNOWN/PARAMETERFILE/SPFILE.272.622486851';

2.
Shutdown and startup mount using the restored spfile
   SQL> startup mount force pfile=/tmp/pfile

3. Restore
the spfile again to the correct location as DB_NAME is correctly set this time.
   RMAN> restore spfile;

4. Startup again using the spfile
   SQL> startup force


UNTIL the next time we had to use "create spfile ...;" the nightmare got back again. L
Eventually we decided to give up this solution and we are using spfile in a regular file system.

Silent Installation

Some times there are problems using installation with GUI, the reason can be: 1. Firewall 2. Unix security 3. Client software (missing or not working( and maybe some more reasons If your environment is cooperative helping you solve this - it is simple - go for it. But if you are on your own and can't reach "the right guys" - do it yourself " Silently " Look for the proper response file fits for your needs in /database/response/ Edit it and run the following command: $ ./runInstaller -force -invPtrLoc /oraInst.loc -silent -noconfig -ignoreSysPrereqs -responseFile /database/response/enterprise.rsp You can also run the installer without a response file as mentioned in Metalink Note 782918.1 $ ./runInstaller -silent -force -debug \ FROM_LOCATION="/mount/dvd/database/stage/products.xml" \ ORACLE_HOME="/u01/app/oracle/product/11.1.0/db_1" \ ORACLE_HOME_NAME="Ora11gDb1" ORACLE_BASE="/u01/app/oracle" \ TOPLEVEL_COMPONENT='{&q

Data Guard - Changing IP Addresses

Image
When changing IP of a host we should update/recheck the following places: /etc/hosts or DNS listener.ora tnsnames.ora Database parameters (local_listener, remote_listener) Data Guard configuration This document is also relevant when changing the IP address of the connection between the hosts, other than the original IP addresses we used during the installation. When installation is done using the hostname and not the IP address, most of the changes are not relevant except for /etc/hosts. In this document, I will describe how to change the Data Guard Broker configuration.
