We came across some nasty effects of our decision to change some paths on our production system.
Let’s start with the present configuration.
The Oracle layer
A Windows 2012 R2 cluster with 4 nodes,
Oracle 11.2.0.4, and the Oracle fail safe miracle stuf
Using mount points for the disks
R:\
<SID>_Data (Oracle Home)
<SID>_LogA (Oracle LogA)
<SID>_LogB (Oracle LogB)
<SID>_Arch (Oracle Archive)
<SID>_Div (Oracle Backup)
E:\
\oracle\<SID>\11204 contains the oracle stuf
The SAP layer
A windows 2012 R2 cluster with 2 nodes,
Sapcentral services
Enqueue replicator
The SAP application Layer
Lots of SAP application servers with DIA/BTC/SPO/
SAP (as configured) uses R:\GEP_Div\sapbackup as the backup disk to place backups.
The environment variable SAPDATA_HOME=R:\<SID>_DATA\ORACLE\<SID>
And now you ask what’s the problem this seems fine if it works, well now for the first time we want to perform a system copy and the problem starts.
The BRRECOVERY tool doesn’t allow you to get the backup files from another location as they were written with the backup. The data.K files are written on R:\<SID>_Div\sapbackup, copied to a different server to W:\sapbackup. Trying to restore ??? no way, You can’t
The only way to come around this, is by altering the backup.and file that seems to work but then the second problem arose.
Control files are not restored due to the fact that brrestore can’t find the files because it’s looking in the wrong directory.
Putting an OSS call just results in “This is consulting” answer and not something like “Oeps thanks for letting us know BRRESTORE has some problems”
So We address to you.
Did anybody come across the problem to restore Oracle datafiles in mixed configurations in a Windows platform? (or Unix, the parameters would be the same we think)
We have seen the parameter –m of brrestore but you can’t use directory’s to be replaced. Or who knows how to use the –p parameter file. –x is undocumented and only drive letters can be changed.
