Errors RMAN-03002 and RMAN-06571 While running SWITCH DATABASE TO COPY on Standby Database

If you are doing a rollforward of a standby database and in the middle of the process got errors like below:

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of switch to copy command at 06/26/2015 23:08:53
RMAN-06571: datafile 301 does not have recoverable copy

Don't worry, you just need to catalog the datafile in question using this command below:

catalog datafilecopy '+DG_EBS_DATA/bwebspr_glt_p7/datafile/apps_ts_tx_idx.584';

You can also use this query below to build the command to you quickly:

select 'catalog datafilecopy '''||name||''';' from v$datafile where file#=301;

After doing that for all problematic datafiles you can finish your rollforward process.

To fox that, run this command below as GRID_HOME owner:

[bwdp0248-+ASM1]/u01/app/>  ./setasmgidwrap o=/u01/app/oracle/product/  --HERE USE YOUR ORACLE RDBMS HOME

This fix my problem.

CellCLI> list cell CELL-01519: Cannot talk to the Management Server (MS). Error: ; nested exception is: HTTP transport error: javax.xml.soap.SOAPException: javax.xml.soap.SOAPException: Bad response: 404 Not Found CellCLI> exit

Hi guys,

I already got problems when I set my cell virtual machine with memory less than 1GB and also when I commented out the "127.x.x.x"  ip address in /etc/hosts file. But this error below was new for me.

To fix that in your TEST virtual machine of Exadata Cell, just do these following steps:

1-Stop the MS service

2-Redeploy the MS oc4j:

3-Start the MS processes:

  The Hardware Options now have the Elastic Rack with Flash Disks (HP disks does not exists anymore) or HC Disks.
  You can choose to have a Virtualized Exadata or all physical db nodes. Also you can choose COD to save money on your software licenses.
Here you see one RAC with 19 nodes and 3 cells.  This is only one from many possibilities:
At the end, your template shows something like that:
