Thank you Thomas....

The LoadMetadata.ksh script

USERID_logon
Code:
userid=user/pwd@db

Code:
#!/usr/bin/ksh

USERID=$1
CONTROL_FILE=$2
DATA_FILE=$3

LOGON=`cat ${PARTNER_DB}/${USERID}_logon`
$ORACLE_HOME/bin/sqlldr $LOGON control=$PARTNER_DB/${CONTROL_FILE} log=$PARTNER_DB/${CONTROL_FILE}.log data=$FILES/temp/${DATA_FILE}

I am calling this Load.ksh through your script....I also need to truncate the opposite table after checking which table is currently in use...

Code:
USERID=$1
DATA_FILE=$2
CONTROL_FILEA=MetadataA.ctl
CONTROL_FILEB=MetadataB.ctl

IFS=$(echo '\012\001') # Newlines only
for LINE in $(
    sqlplus -s /nolog <<!
        CONNECT ${DB_USER}/${DB_PASSWORD}@${DB_NAME}
        SET FEEDBACK OFF VERIFY OFF ECHO OFF PAGES 0 TRIMSPOOL ON
        COL text FORMAT A150 FOLD_AFTER
        SELECT CASE
                   WHEN table_name = 'ACXIOM_METADATA_A'
                       THEN 'LoadMetadata.ksh ${USERID} ${CONTROL_FILEB} ${DATA_FILE}'
                       ELSE 'LoadMetadata.ksh ${USERID} ${CONTROL_FILEA} ${DATA_FILE}'
               END text
              ,CASE
                   WHEN table_name = 'ACXIOM_METADATA_A'
                       THEN 'dml_cmd=CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_B'
                       ELSE 'dml_cmd=CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_A'
               END text
        FROM   all_synonyms
        WHERE  synonym_name = 'ACXIOM_METADATA';
!)
do
    case ${LINE} in
        dml*)    DML_CMD=${LINE##*=} ;;
        sqlldr*) SQLLDR_TBL=${LINE##*=} ;;
    esac
done
print ${DML_CMD}
print ${SQLLDR_TBL}

dbix::searchbuilder::handle::oracle

DBIx::SearchBuilder::Handle::Oracle(3pm)		User Contributed Perl Documentation		  DBIx::SearchBuilder::Handle::Oracle(3pm)

NAME

	 DBIx::SearchBuilder::Handle::Oracle - An oracle specific Handle object

SYNOPSIS

DESCRIPTION

       This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of Oracle.

METHODS

   Connect PARAMHASH: Driver, Database, Host, User, Password
       Takes a paramhash and connects to your DBI datasource.

   BuildDSN
       Customized version of "BuildDSN" in DBIx::SearchBuilder::Handle method.

       Takes additional argument SID. Database argument used unless SID provided.  Two forms of DSN are generated depending on whether Host
       defined or not:

	   dbi:Oracle:sid=<SID>;host=...[;port=...]
	   dbi:Oracle:<SID>

       Read details in documentation for DBD::Oracle module.

   Insert
       Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.

   InsertFromSelect
       Customization of "InsertFromSelect" in DBIx::SearchBuilder::Handle.

       Unlike other DBs Oracle needs:

       o   id generated from sequences for every new record.

       o   query wrapping in parens.

       NOTE that on Oracle there is a limitation on the query. Every column in the result should have unique name or alias, for example the
       following query would generate "ORA-00918: column ambiguously defined" error:

	   SELECT g.id, u.id FROM ...

       Solve with aliases:

	   SELECT g.id AS group_id, u.id AS user_id FROM ...

   KnowsBLOBs
       Returns 1 if the current database supports inserts of BLOBs automatically.  Returns undef if the current database must be informed of BLOBs
       for inserts.

   BLOBParams FIELD_NAME FIELD_TYPE
       Returns a hash ref for the bind_param call to identify BLOB types used by the current database for a particular column type.  The current
       Oracle implementation only supports ORA_CLOB types(112).

   ApplyLimits STATEMENTREF ROWS_PER_PAGE FIRST_ROW
       takes an SQL SELECT statement and massages it to return ROWS_PER_PAGE starting with FIRST_ROW;

   DistinctQuery STATEMENTREF
       takes an incomplete SQL SELECT statement and massages it to return a DISTINCT result set.

   BinarySafeBLOBs
       Return undef, as Oracle doesn't support binary-safe CLOBS

   DatabaseVersion
       Returns value of ORA_OCI constant, see "Constants" in DBI.

   SimpleDateTimeFunctions
       Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.

   ConvertTimezoneFunction
       Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.

       Use the following query to get list of timezones:

	   SELECT tzname FROM v$timezone_names;

       Read Oracle's docs about timezone files:

	   http://download.oracle.com/docs/cd/B14117_01/server.101/b10749/ch4datetime.htm#i1006667
