11g: unable to use rman as side effect of having optimizer_capture_sql_plan_baselines=TRUE (ORA-00376)

Hi list members,

just want to make you aware of the following issue that might occur
when optimizer_capture_sql_plan_baselines is set to TRUE in 11g.
My case was RAC with 11.1.0.7 + cpuJuly2009 + Linux_x86_64

At some point I noticed a ORA-376 appearing and all dictionary queries
failing Even the use of rman with nocatalog failed:

mad> rman target / nocatalog

RMAN-00571: ===========================================================

RMAN-00554: initialization of internal recovery manager package failed

ORA-00376: file 2 cannot be read at this time
ORA-01110: data file 2: '+DATA/jaja/datafile/sysaux.275.693506063'
.
running rman with debug turned on (rman target / nocatalog debug
trace=rman.trc) showed it was failing on
  select decode(archiver, 'FAILED', 1, 0) into :archstuck from v$instance:
DBGSQL:          sqlcode = 376 [15:50:45.008]
DBGSQL:       error: ORA-00376: file 2 cannot be read at this time

DBGSQL:       ORA-01110: data file 2:
'+DGRP_DATA/jaja/datafile/sysaux.275.693506063' (krmkosqlerr)
.
workaround was to set optimizer_capture_sql_plan_baselines to FALSE
and then restart
.
Thanks to Oracle support for this suggestion that worked.

Regards,
Andre
