问题：

I am new to ASM and I am trying to move my non-ASM database to an ASM database.

?

Here is the situation :

- 1 ASM database version 12.1.0.2.0

- 1 non-ASM database version 11.2.0.1.0

- ASM database is up and running and the diskgroup is mounted

- non-ASM database is also up and running

- Cluster Synchronization Services seems ok,I issued the following command :

$ crsctl check css

$ CRS-4529: Cluster Synchronization Services is online

?

So far,to move my database to an ASM-database I performed the following steps :

?

1. Changed the location of my non-ASM control_file parameter to my created ASM disks

SQL> alter system set control_files=‘+DGROUP1‘ scope=spfile;

?

2. Set the parameter DB_CREATE_FILE_DEST to my ASM disk

SQL> alter system set db_create_file_dest=‘+DGROUP1‘ scope=spfile;

?

3. Shutdown and startup nomount my non-ASM database

SQL> shutdown immediate

SQL> startup nomount

?

4. Restored control file from the existing one

rman target /

restore controlfile from ‘/oracle/dbfile/ORCL/ORCL/control01.ctl‘;

?

This is where I am stuck as I have the following error :

?

ORA-19600: input file is control file? (/oracle/dbfile/ORCL/ORCL/control01.ctl)

ORA-19601: output file is control file? (+DGROUP1)

?

Does anyone as an idea on how to fix this issue ?

?

Thanks very much,

答案：

:

Yep,where is the error:

?

TNS-00517: Lost contact

??? nt secondary err code: 32

??? nt OS err code: 0

ERROR: Failed to connect with connect string:?(DESCRIPTION=(ADDRESS=(PROTOCOL=beq)(PROGRAM=/grid/app/oracle/product/11.2.0/grid2/bin/oracle)(ARGV0=oracle+ASM_asmb_orcl)(ENVS=‘ORACLE_HOME=/grid/app/oracle/product/11.2.0/grid2,ORACLE_SID=+ASM‘)(ARGS=‘(DESCRIPTION=(LOCAL=YES)(ADDRESS=(PROTOCOL=beq)))‘))(enable=setuser))

?

The error has to do with permissions in your directory. Follow the steps in this article to fix the issue.

?

You have to change the permission on

$GRID_HOME/bin/

chmod 6751 oracle

?

And $ORACLE_HOME/bin/

chmod 6751 oracle

?

Then try again.
