Probably this is along the lines of what you want:
WARNING: This is not tested so you assume the risks if you're going to simply paste it into you Load.ksh script.
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 'TRUNCATE TABLE ACXIOM_METADATA_B;'
                    ELSE 'TRUNCATE TABLE ACXIOM_METADATA_A;'
               END text
              ,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 'CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_B'
                    ELSE '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
        TRUNCATE*|CREATE*)
            sqlplus -s /nolog <<!
connect un/pw
${LINE}
!
 ;;
        LoadMetadata*) exec ${LINE} ;;
    esac
done

This will perform the command in this order:
  1. sqlplus TRUNCATE TABLE ACXIOM_METADATA_B;
  2. LoadMetadata.ksh ${USERID} ${CONTROL_FILEB} ${DATA_FILE}
  3. sqlplus CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_b;

Thank you again Thomas..

I have loaded a sample of 4 rows in to Table B. Switched the synonym to have Table B and then ran the script...

Code:
USERID=$1
DATA_FILE=$2
CONTROL_FILEA=prtnrAcxiomMetadataA.ctl
CONTROL_FILEB=prtnrAcxiomMetadataB.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 'TRUNCATE TABLE PARTNERDBA.ACXIOM_METADATA_B;'
                    ELSE 'TRUNCATE TABLE PARTNERDBA.ACXIOM_METADATA_A;'
               END text
              ,CASE WHEN table_name = 'ACXIOM_METADATA_A'
                    THEN 'prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEB} ${DATA_FILE}'
                    ELSE 'prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEA} ${DATA_FILE}'
               END text
              ,CASE WHEN table_name = 'ACXIOM_METADATA_A'
                    THEN 'CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_B'
                    ELSE '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
        TRUNCATE*|CREATE*)
            sqlplus -s /nolog <<!
connect ${DB_USER}/${DB_PASSWORD}@${DB_NAME}
${LINE}
!
 ;;
        prtnrLoadMetadata*) exec ${LINE} ;;
    esac
done

The script didn't truncate Table B, didn't load Table A and didn't replace the synonym to Table A.

The scripts is easy to understand but I am not sure why it is not executing anything...I wish I would atleast see any messages printing...

Looks like the quotes were getting clobbered. Try moving the SQL into a variable as follows:
Code:
USERID=$1
DATA_FILE=$2
CONTROL_FILEA=prtnrAcxiomMetadataA.ctl
CONTROL_FILEB=prtnrAcxiomMetadataB.ctl

IFS=$(echo '\012\001') # Newlines only
SQL="
        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 'TRUNCATE TABLE PARTNERDBA.ACXIOM_METADATA_B;'
                    ELSE 'TRUNCATE TABLE PARTNERDBA.ACXIOM_METADATA_A;'
               END text
              ,CASE WHEN table_name = 'ACXIOM_METADATA_A'
                    THEN 'prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEB} ${DATA_FILE}'
                    ELSE 'prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEA} ${DATA_FILE}'
               END text
              ,CASE WHEN table_name = 'ACXIOM_METADATA_A'
                    THEN 'CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_B'
                    ELSE 'CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_A'
               END text
        FROM   all_synonyms
        WHERE  synonym_name = 'ACXIOM_METADATA';
"
for LINE in $(
    sqlplus -s /nolog <<EOF
    ${SQL}
EOF)
do
    case ${LINE} in

No Luck Thomas...

Output

Code:
Connected.

0 rows deleted.

Connected.

I changed the TRUNCATE statement to just DELETE...It is not going further down the script to execute the shell script and also switch synonym..

Code:
USERID=$1
DATA_FILE=$2
CONTROL_FILEA=prtnrAcxiomMetadataA.ctl
CONTROL_FILEB=prtnrAcxiomMetadataB.ctl


IFS=$(echo '\012\001') # Newlines only

        CONNECT ${DB_USER}/${DB_PASSWORD}@${DB_NAME}
        SET FEEDBACK OFF VERIFY OFF ECHO OFF PAGES 0 TRIMSPOOL ON

        SELECT
               CASE WHEN table_name = 'ACXIOM_METADATA_A'
                    THEN 'DELETE PARTNERDBA.ACXIOM_METADATA_B;'

Check the syntax; it's fairly simple to find the bugs at this point Smilie

1) You changed:
Code:
THEN 'prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEB} ${DATA_FILE}'
ELSE 'prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEA} ${DATA_FILE}'

to:
Code:
THEN '$PARTNER_DB/prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEB} ${DATA_FILE}'
ELSE '$PARTNER_DB/prtnrLoadMetadata.ksh ${USERID} ${CONTROL_FILEA} ${DATA_FILE}'

therefore, you must change the KSH expression that you are looking for:
Code:
case
...
    $PARTNER_DB/prtnrLoadMetadata*) exec ${LINE} ;;
...
esac

or

case
...
    *prtnrLoadMetadata*) exec ${LINE} ;;
...
esac

2) We both simply missed the missing semicolon here:
Code:
THEN 'CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_B;'  <===
ELSE 'CREATE OR REPLACE PUBLIC SYNONYM ACXIOM_METADATA FOR ACXIOM_METADATA_A;'  <===

Conclusions:
  1. Korn shell can't guess where all your strings are changing. Make sure that your case statement can actually match the patter returning from sqlplus
  2. SQL must be valid SQL. Check those semicolons.

Thank you very much for the conclusions....I am still learning a whole lot of it...

I have also changed it as per your suggestions...But I think I am going wrong somewhere....It is not recognizing the shell script inside the SQL.

Code:
Connected.

0 rows deleted.

prtnrSynonym.ksh[57]: /partnerdb/bin/prtnrLoadMetadata.ksh dataload prtnrAcxiomMetadataA.:  not found

I tried both ways....

*prtnrLoadMetadata* and $PARTNER_DB/prtnrLoadMetadata*

Code:

DATA_FILE=$2

CONTROL_FILEB=prtnrAcxiomMetadataB.ctl

Sorry, my bad again!

Your line is getting chopped from sqlplus so change:
Code:
SET FEEDBACK OFF VERIFY OFF ECHO OFF PAGES 0 TRIMSPOOL ON

to:

Code:
SET FEEDBACK OFF VERIFY OFF ECHO OFF PAGES 0 TRIMSPOOL ON LINES 300

This gives you enough space for your path and filename. Add more if 300 character isn't enough.

I also changed this:
Code:
        $PARTNER_DB/prtnrLoadMetadata*) exec ${LINE} ;;

to:
Code:
        $PARTNER_DB/prtnrLoadMetadata*) eval ${LINE} ;;
