Hi!

I am having a strange problem with an Oracle 12.1.0.2 instance on SUN Solaris 11.3 (SPARC):

ORA-01110: data file 7: '/oradata/DEV/datafiles/data01b.dbf' 2017-04-28 23:05:11.723000 -04:00 Flush retried for xcb 0x5c0e98a90, pmd 0x5c3faa538 Errors in file /app/oradev/diag/rdbms/oradev/DEV/trace/DEV_pmon_465049.trc: ORA-00372: file 7 cannot be modified at this time ORA-01110: data file 7: '/oradata/DEV/datafiles/data01b.dbf' 2017-04-28 23:05:18.756000 -04:00 Flush retried for xcb 0x5c0e98a90, pmd 0x5c3faa538 Errors in file /app/oradev/diag/rdbms/oradev/DEV/trace/DEV_dbw0_465083.trc: ORA-00372: file 7 cannot be modified at this time ORA-01110: data file 7: '/oradata/DEV/datafiles/data01b.dbf' USER (ospid: 465083): terminating the instance due to error 372 System state dump requested by (instance=1, osid=4295432379 (DBW0)), summary=[abnormal instance termination]. System State dumped to trace file /app/oradev/diag/rdbms/oradev/DEV/trace/DEV_diag_465073_20170428230518.trc 2017-04-28 23:05:23.820000 -04:00 Instance terminated by USER, pid = 465083 2017-04-29 10:58:13.293000 -04:00 Starting ORACLE instance (normal) (OS id: 44563) CLI notifier numLatches:29 maxDescs:1355 All SGA segments were allocated at startup

When I restart the instance all files are available. The instance is patched with the January 2017 PSU, soon to be patched with April 2017 PSU. Here are the relevant versions:

SunOS sun02 5.11 11.3 sun4v sparc sun4v -bash-4.4$ sqlplus / as sysdba SQL*Plus: Release 12.1.0.2.0 Production on Sun Apr 30 16:15:43 2017 Copyright (c) 1982, 2014, Oracle. All rights reserved. Connected to: Oracle Database 12c Enterprise Edition Release 12.1.0.2.0 - 64bit Production With the Partitioning, OLAP, Advanced Analytics and Real Application Testing options

The underlying file system is, of course, ZFS. When the instance is restarted, all the files are available and there is nothing in the V$RECOVER_FILE. I opened SR with Oracle, but as this is a development system, they are taking their time. Has anyone seen this before and, if yes, what would be the solution? The system crashes during nightly batches, which load a lot of data and are write intensive.
