Control not returning from Sqlplus to calling UNIX shell script.

Hello All,

I have a UNIX script which will prepare anonymous oracle pl/sql block in a temporary file in run time and passes this file to sqlplus as given below.


Code:
cat > $v_Input_File 2>>$v_Log << EOF
BEGIN
EXECUTE IMMEDIATE 'ALTER SESSION FORCE PARALLEL DML PARALLEL 16';

EXECUTE IMMEDIATE 'INSERT /*+ APPEND */ INTO $v_Tbl SELECT  ${v_Primary_Key},${v_Col_List} FROM ${v_SRC_DB_NM}.${v_SRC_TBL_NM} T
WHERE SOME_DATE > TO_TIMESTAMP(''$v_START_DTTM'',''YYYY-MM-DD HH24:MI:SS.FF'') 
AND CSOME_DATE <= TO_TIMESTAMP(''$v_END_DTTM'',''YYYY-MM-DD HH24:MI:SS.FF'')';

COMMIT;

END;
/

EOF

#--------------------

sqlplus -s "$Oracle_User/$Oracle_Pwd@$Oracle_Conn_String" <<EOF  >> $v_Log 2>&1
	WHENEVER OSERROR EXIT 9;
	WHENEVER SQLERROR EXIT SQL.SQLCODE;
	SET LINESIZE 32000
	SET FEEDBACK ON
	SET HEADING OFF
	SET ECHO ON
	SET TIME ON
	SET TIMING ON
	SET SERVEROUTPUT ON

	`cat $v_Input_File`
EOF

if [ $? -eq 0 ]
then
   echo "Completed successfully"
   exit 0
else
   echo "Failed"
   exit 1
end if

The issue here is insert query runs around 2.5-3 hours and commits successfully on the oracle side. But the script is waiting indefinitely for return status from sqlplus and neither failing nor succeeding.

The same sqlplus functionality is working fine for queries that take less time like 1hr or so.

If any one can help me in this regard that would be really great.

Thanks in advance.

SET 
ROLE(7) PostgreSQL 9.2.7 Documentation SET ROLE(7) NAME
SET_ROLE - set the current user identifier of the current session SYNOPSIS
SET [ SESSION | LOCAL ] ROLE role_name SET [ SESSION | LOCAL ] ROLE NONE RESET ROLE DESCRIPTION
This command sets the current user identifier of the current SQL session to be role_name. The role name can be written as either an identifier or a string literal. After SET ROLE, permissions checking for SQL commands is carried out as though the named role were the one that had logged in originally. The specified role_name must be a role that the current session user is a member of. (If the session user is a superuser, any role can be selected.) The SESSION and LOCAL modifiers act the same as for the regular SET(7) command. The NONE and RESET forms reset the current user identifier to be the current session user identifier. These forms can be executed by any user. NOTES
Using this command, it is possible to either add privileges or restrict one's privileges. If the session user role has the INHERITS attribute, then it automatically has all the privileges of every role that it could SET ROLE to; in this case SET ROLE effectively drops all the privileges assigned directly to the session user and to the other roles it is a member of, leaving only the privileges available to the named role. On the other hand, if the session user role has the NOINHERITS attribute, SET ROLE drops the privileges assigned directly to the session user and instead acquires the privileges available to the named role. In particular, when a superuser chooses to SET ROLE to a non-superuser role, she loses her superuser privileges. SET ROLE has effects comparable to SET SESSION AUTHORIZATION (SET_SESSION_AUTHORIZATION(7)), but the privilege checks involved are quite different. Also, SET SESSION AUTHORIZATION determines which roles are allowable for later SET ROLE commands, whereas changing roles with SET ROLE does not change the set of roles allowed to a later SET ROLE. SET ROLE does not process session variables as specified by the role's ALTER ROLE (ALTER_ROLE(7)) settings; this only happens during login. SET ROLE cannot be used within a SECURITY DEFINER function. EXAMPLES
SELECT SESSION_USER, CURRENT_USER; session_user | current_user --------------+-------------- peter | peter SET ROLE 'paul'; SELECT SESSION_USER, CURRENT_USER; session_user | current_user --------------+-------------- peter | paul COMPATIBILITY
PostgreSQL allows identifier syntax ("rolename"), while the SQL standard requires the role name to be written as a string literal. SQL does not allow this command during a transaction; PostgreSQL does not make this restriction because there is no reason to. The SESSION and LOCAL modifiers are a PostgreSQL extension, as is the RESET syntax. SEE ALSO
