Alter Session Not working in Oracle job and procedure

Hi ,
I need to run a monthly job in oracle which takes data from a remote database and fills it into my database.
To Connect to the remote database I have a db link created. Even after
the creation of dblink the table could not be accessed because of name issues in dblink and database name.

Hence I added the statement " alter session set global_names='false' " before my insert queries . When I run it as a script it works fine and fetches the data.

The following works as a script:

alter session set global_names='false';
select * from abc.domainname.com

My problem is when I put these statements in a job and a procedure alter session doesn't seem to work.

The only modication I made for it to run in a job is

execute immediate ' alter session set global_names='false' '
select * from abc.domainname.com


This gives me the same previous error which came before adding the alter session in the script.


Kindly suggest how to tackle this................

and what happens ....

Syntax error.

Check your syntax...

Code:

---

select 'alter session set global_names='false''
from    dual;

---

Now check this syntax...

Code:

---

select 'alter session set global_names='''||'false'||''''
from    dual;

@davey : I get the following error

ORA-04052: error occurred when looking up remote object CHGMGT.ALL_AOTS_CRS@IC3.STC.COM
ORA-00604: error occurred at recursive SQL level 1
ORA-02085: database link IC3.STC.COM connects to IC3

This error was resolved when I just run as a script with Alter session set global_names='false' and I was able to fetch data , but Alter session doesnt work in a job.

@PAVB: I tried the syntax you gave me.Following is my procedure in the forms I have tried to alter the session:

Tried By me:

1.)
CREATE OR REPLACE PROCEDURE CHM_KPI_AUTO IS
v_cnt number;
BEGIN

execute immediate 'Alter session set global_name=false';
select count(*) into v_cnt from CHGMGT.ALL_AOTS_CRS@ic3.stc.com a where
a.ITEM = 'PREAPPR' and
a.PLANNED_START_MONTH = (select UPPER(to_char(add_months(sysdate,-1), 'mon')) from dual)
and a.PLANNED_START_YEAR = (select DECODE (UPPER(to_char(add_months(sysdate,-1), 'mon')),'DEC',to_char(to_char(sysdate,'yyyy')-1),to_char(sysdate,'yyyy')) from dual);

END;

2.)


CREATE OR REPLACE PROCEDURE CHM_KPI_AUTO IS
v_cnt number;
BEGIN

execute immediate 'Alter session set global_name='false'';
select count(*) into v_cnt from CHGMGT.ALL_AOTS_CRS@ic3.stc.com a where
a.ITEM = 'PREAPPR' and
a.PLANNED_START_MONTH = (select UPPER(to_char(add_months(sysdate,-1), 'mon')) from dual)
and a.PLANNED_START_YEAR = (select DECODE (UPPER(to_char(add_months(sysdate,-1), 'mon')),'DEC',to_char(to_char(sysdate,'yyyy')-1),to_char(sysdate,'yyyy')) from dual);

END;



As Suggested by you:
1.)
CREATE OR REPLACE PROCEDURE CHM_KPI_AUTO IS
v_cnt number;
BEGIN

execute immediate 'alter session set global_names='''||'false'||''''
;
select count(*) into v_cnt from CHGMGT.ALL_AOTS_CRS@ic3.stc.com a where
a.ITEM = 'PREAPPR' and
a.PLANNED_START_MONTH = (select UPPER(to_char(add_months(sysdate,-1), 'mon')) from dual)
and a.PLANNED_START_YEAR = (select DECODE (UPPER(to_char(add_months(sysdate,-1), 'mon')),'DEC',to_char(to_char(sysdate,'yyyy')-1),to_char(sysdate,'yyyy')) from dual);

END;


2.)


CREATE OR REPLACE PROCEDURE CHM_KPI_AUTO IS
v_cnt number;
a_cnt number;
BEGIN

select 'alter session set global_names='''||'false'||'''' into a_cnt
from dual;
select count(*) into v_cnt from CHGMGT.ALL_AOTS_CRS@ic3.stc.com a where
a.ITEM = 'PREAPPR' and
a.PLANNED_START_MONTH = (select UPPER(to_char(add_months(sysdate,-1), 'mon')) from dual)
and a.PLANNED_START_YEAR = (select DECODE (UPPER(to_char(add_months(sysdate,-1), 'mon')),'DEC',to_char(to_char(sysdate,'yyyy')-1),to_char(sysdate,'yyyy')) from dual);

END;




So my problem is that I need to use Alter Session in a job or a procedure but it doesn't seem to work since I get the same error which I got while executing as a script and not using alter session.

The script that runs perfectly is

Alter session set global_names=false;
select count(*) into v_cnt from CHGMGT.ALL_AOTS_CRS@ic3.stc.com a where
a.ITEM = 'PREAPPR' and
a.PLANNED_START_MONTH = (select UPPER(to_char(add_months(sysdate,-1), 'mon')) from dual)
and a.PLANNED_START_YEAR = (select DECODE (UPPER(to_char(add_months(sysdate,-1), 'mon')),'DEC',to_char(to_char(sysdate,'yyyy')-1),to_char(sysdate,'yyyy')) from dual);




Any Help is greatly appreciated......

Jaieesh --

What I gave you was a way to test if syntax was correct or not.

What you have to include in your code is:
execute immediate 'alter session set global_names='''||'false'||''''

@PAVB

Syntax of alter session was ok. Changed it to as suggested by you.

CREATE OR REPLACE PROCEDURE CHM_KPI_AUTO
IS
v_cnt number;
BEGIN
v_cnt:=0;
execute immediate 'alter session set global_names='''||'false'||'''' ;
select count(*) as KPI_1_APR_Numerator into v_cnt from CHGMGT.ALL_AOTS_CRS@ic4.sbc.com a where
a.ITEM = 'PREAPPR' and
a.PLANNED_START_MONTH = (select UPPER(to_char(add_months(sysdate,-1), 'mon')) from dual)
and a.PLANNED_START_YEAR = (select DECODE (UPPER(to_char(add_months(sysdate,-1), 'mon')),'DEC',to_char(to_char(sysdate,'yyyy')-1),to_char(sysdate,'yyyy')) from dual);

END;


Still get the same db link error which comes when global_names is set to true.
