DB_UNKNOWN directory created after an attempt of copying a pwfile to ASM

brunors

I was trying to copy a password file from a file system to the ASM. Every time I tried to copy this file, I noticed that the directory named “DB_UNKNOWN” was created. This error usually happens when the database unique_name (resource) is not configured into the CRS and the output can be seen as below:

[oracle@techdaserver dbs]$ . oraenv
ORACLE_SID = [TECHDB] ? +ASM1
The Oracle base remains unchanged with value /u01/app/oracle
[oracle@techdaserver dbs]$ asmcmd
ASMCMD> pwcopy '/u01/app/oracle/19.3.0/db/dbs/orapwTECHDB' '+DATA/TECHDB/PASSWORD/'
copying /u01/app/oracle/19.3.0/db/dbs/orapwTECHDB -> +DATA/TECHDB/PASSWORD/
ASMCMD> ls -ltr +DATA/TECHDB/PASSWORD/
WARNING:option 'r' is deprecated for 'ls'
please use 'reverse'

Type      Redund  Striped  Time             Sys  Name

To fix this issue, you must use the “–dbuniquename” clause while copying a file from disk to the ASM:

[oracle@techdaserver dbs]$ . oraenv
ORACLE_SID = [TECHDB] ? +ASM1
The Oracle base remains unchanged with value /u01/app/oracle
[oracle@techdaserver dbs]$ asmcmd
ASMCMD>  pwcopy --dbuniquename TECHDB '/u01/app/oracle/19.3.0/db/dbs/orapwTECHDB' '+DATA/TECHDB/PASSWORD/'
copying /u01/app/oracle/19.3.0/db/dbs/orapwTECHDB -> +DATA/TECHDB/PASSWORD/orapwTECHDB
ASMCMD> ls -ltr  +DATA/TECHDB/PASSWORD/
WARNING:option 'r' is deprecated for 'ls'
please use 'reverse'

Type      Redund  Striped  Time             Sys  Name
PASSWORD  UNPROT  COARSE   AUG 19 12:00:00  N    orapwTECHDB => +DATA/TECHDB/PASSWORD/pwdTECHDB.282.1080996329
PASSWORD  UNPROT  COARSE   AUG 19 12:00:00  Y    pwdTECHDB.282.1080996329

I hope that this post helps you!
