How to connect to ASM Instance Remotely

1) Edit the listener.ora on ASM server

   a) Logon to the ASM/Database server

   b) Locate your listener.ora (typically located in the $ORACLE_HOME/network/admin)

   c) Add a SID_LIST_LISTENER entry for your ASM instance (see example below)

EXAMPLE


   d) Stop the listener


   e) restart the listener



2) Edit the tnsnames.ora on the client
   a) Logon to the client machine that will be used to connect to the ASM instance
          NOTE: the client machine can also be the ASM/Database server (ie for DBCONTROL)

   b) Locate your tnsnames.ora (typically in the $ORACLE_HOME/network/admin)
   c) Add an entry (tnsalias) for your ASM instance (see example)
EXAMPLE


3) Setup your remote login password for your ASM instance on the ASM server
   a) Logon to the ASM/Database server

   b) Locate the parameter file for your ASM instance (typically $ORACLE_HOME/dbs/init+ASM.ora [unix] or $ORACLE_HOME/dbs/init+ASM.ora [windows] )

   c) Edit the parameter file and add

         remote_login_passwordfile = exclusive ... for stand alone ASM setups
         remote_login_passwordfile = shared ... for ASM setups that also use Real Application Cluster (RAC)
     d) Save the file
   NOTE: It may be required that an PFILE be created from an SPFILE in order to be able to edit the file properly ... once the line have been added ... the process can be reversed
                 For more details Note 249664.1 Pfile vs SPfile ... may be used

4) Set your SYS password using ORAPWD for the ASM instance

   a) Logon to the ASM/Database server

   b) Locate your orapw<sid> file for your ASM instance (typically $ORACLE_HOME/dbs/orapw+ASM)

   c) Rename the file to orapw<sid>.old
 
   d) Run orapwd to reset the password (see example below)

EXAMPLE

5) Use the properly formatted connect string for your tool
Connnect to the ASM instance using the password (#4 above) and the tnsalias (#2 above)
