ASM Instance Issues

ASMCMD-08102: no connection to ASM; command requires ASM to run
[oracle@Jaya ~]$ asmcmd
Connected to an idle instance.
ASMCMD> ls -L +DATA
ASMCMD-08102: no connection to ASM; command requires ASM to run

Solution :
We need to Set ASM Instance Oracle home path
[oracle@jaya ~]$ export ORACLE_HOME=/u01/app/oracle/product/11.2.0/grid
[oracle@jaya ~]$ export PATH=/u01/app/oracle/product/11.2.0/grid/bin
[oracle@jaya ~]$ export ORACLE_SID=+ASM
[oracle@jaya ~]$ asmcmd
ASMCMD> ls -L +DATA/DBASM/DATAFILE
SYSAUX.257.753010705
SYSTEM.256.753010703
TESTTBS.275.753248961

ASMCMD>
ORA-01565: error in identifying file /dbs/spfile@.ora
When we’re going to create pfile from spfile while spfile running on ASM instance, We can face the below errors,
SQL> create pfile=’/u01/inittest.ora’ from spfile;
create pfile=’/u01/inittest.ora’ from spfile
*
ERROR at line 1:
ORA-01565: error in identifying file ‘?/dbs/spfile@.ora’
ORA-27037: unable to obtain file status
Linux Error: 2: No such file or directory
Additional information: 3
Solution :
We need to give ASM path of SPFILE.
SQL> create pfile=’/u01/inittest.ora’ from spfile=’+DATA/dbasm/spfiledbasm.ora’;
File created.

Can I Store Datapump dumpfiles in ASM diskgroup?
 Now we can see How do we create directory and store dumpfile.
Step 1: Go To ASM Instance and Create New Directory.

SQL> alter diskgroup data add directory '+DATA/dumpset';
Diskgroup altered.
 Step 2:  Go to DB Instance 
Create Directory for dumpfile and logfile 
Dumpfile Directory (ASM Disk)
SQL> create or replace directory dp_asm as '+DATA/dumpset';
Directory created.

Log file Directory (Local File System).
SQL> create or replace directory logfile as 'C:\raju';
Directory created.
SQL> grant read,write on directory dp_asm to system;
Grant succeeded.
SQL> grant read,write on directory logfile to system;
Grant succeeded

Step 3: Doing Export using datapump
SQL> $expdp system/Admin123 directory=dp_asm dumpfile=testasm.dmp schemas=scott
logfile=logfile:testasm.log

  2. Hi goutham,

    It's common issue only, no need to worry,
    solution:set the environment variables and check the asmcmd command

    thanks & regards
    Raju
