Hi all, I haven't done a restore/recovery in a looong time. So long in fact, that we were not using RMAN the last time I did. Anyway, I am going through a test recovery and restoring the controlfile and spfile worked, but after restoring the spfile, I am unable to mount the database. I get the following error: RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS =============== RMAN-00571: =========================================================== RMAN-03002: failure of alter db command at 02/22/2006 15:43:28 ORA-00209: control file blocksize mismatch, check alert log for more info The alert log says this: alter database mount Wed Feb 22 15:43:25 2006 ORA-00218: block size 8192 of controlfile does not match DB_BLOCK_SIZE (4096) ORA-00202: controlfile: '?/dbs/cntrl@.dbf' Wed Feb 22 15:43:28 2006 ORA-209 signalled during: alter database mount... however, when I look in the spfile, I see: *.db_block_size=8192 Am I missing something? This is using Oracle 9.2.0.4 on AIX 5.2. TIA -- Stephen
