RMAN corrupts passwordfile

please, can you clarify this? My configuration is RAC 12c on ASM on SLES 11 SP 4 on SystemZ. The nodes **rac11** and **rac12** are the server nodes of the primary database, named "primdb", uniq_name is "primdb". The instance names are **prim1** and **prim2** correspondingly. The nodes **rac21** and **rac22** are nodes of the standby database named "primdb", uniq name is "stdbydb". The instance names are **stdby1** and **stdby2** correspondingly. So, I'm trying to create physical standby using RMAN active duplication. After configuring such parameters as log_archive_dest, dump_dest, and so on I copied password file to the standby server and changed init-file. I added static entry to the listener on **rac21** (not SCAN-address) with service name of the **stdby1** instance and was able to connect to "nomount" database as SYS from any of my servers. $>su - oracle $> . oraenv ORACLE_SID = [oracle] ? stdby1 ORACLE_HOME = [/home/oracle] ? /u01/app/oracle_home The Oracle base has been set to /u01/app/oracle_base $>sqlplus / as sysdba SQL>startup nomount pfile='/tmp/initstdby1.ora' after that i perform the following: $> rman target sys/q1@primdb auxiliary sys/q1@stdby1 > connected to target database: PRIMDB (DBID=636407725) > connected to auxiliary database: PRIMDB (not mounted) $>duplicate target database for standby from active database nofilenamecheck; And on the step of executing memory script (sorry, i can't paste all RMAN output here) a wild error appears > RMAN-00571: > =========================================================== RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS > =============== RMAN-00571: =========================================================== RMAN-00554: initialization of internal recovery manager package failed > RMAN-04006: error from auxiliary database: ORA-00600: internal error > code, arguments: [kzsrsea_ext], [], [], [], [], [], [], [], [], [], > [], [] > -------------------------------------------> After that i'm not able to connect to this nomount database using sql*Net, the same error ORA-600 appears . The only way to connect to this database instance is to connect locally sqlplus / as sysdba And the interesting moment - if i copy the passwordfile again from the primary database to standby, i can connect to this standby database instance. So i think, that RMAN changes my passwordfile on the standby server. I searched for the same error on MOS (Doc ID:1136834.1 ), but they suggest to use backups as the workaround, which is not suitable for me. Any help would be much appreciated..
