Environment Variables from database table - Oracle E-Business Suite

Are you running Oracle E-Business Suite (EBS) / Applications and want to get an operating system level environment variable value from a database table, for example for use in PL/SQL? Or perhaps to default a concurrent program parameter? Didn't think environment variables were stored in the database?

Try out out this query that shows you $FND_TOP:

select value
from   fnd_env_context
where  variable_name = 'FND_TOP'
and    concurrent_process_id = 
      ( select max(concurrent_process_id) from fnd_env_context );

VALUE
--------------------------------------------------------------------------------
/d01/oracle/VIS/apps/apps_st/appl/fnd/12.0.0

Or did you want to find out the Product "TOP" directories e.g the full directory path values from fnd_appl_tops under APPL_TOP?

col variable_name format a15
col value format a64
select variable_name, value
from   fnd_env_context
where  variable_name like '%\_TOP' escape '\'
and    concurrent_process_id = 
     ( select max(concurrent_process_id) from fnd_env_context )
order by 1;

VARIABLE_NAME   VALUE
--------------- ----------------------------------------------------------------
AD_TOP          /d01/oracle/VIS/apps/apps_st/appl/ad/12.0.0
AF_JRE_TOP      /d01/oracle/VIS/apps/tech_st/10.1.3/appsutil/jdk/jre
AHL_TOP         /d01/oracle/VIS/apps/apps_st/appl/ahl/12.0.0
AK_TOP          /d01/oracle/VIS/apps/apps_st/appl/ak/12.0.0
ALR_TOP         /d01/oracle/VIS/apps/apps_st/appl/alr/12.0.0
AME_TOP         /d01/oracle/VIS/apps/apps_st/appl/ame/12.0.0
AMS_TOP         /d01/oracle/VIS/apps/apps_st/appl/ams/12.0.0
AMV_TOP         /d01/oracle/VIS/apps/apps_st/appl/amv/12.0.0
AMW_TOP         /d01/oracle/VIS/apps/apps_st/appl/amw/12.0.0
APPL_TOP        /d01/oracle/VIS/apps/apps_st/appl
AP_TOP          /d01/oracle/VIS/apps/apps_st/appl/ap/12.0.0
AR_TOP          /d01/oracle/VIS/apps/apps_st/appl/ar/12.0.0
...

Or perhaps the full directory path to $APPLTMP?

select value
from   fnd_env_context
where  variable_name = 'APPLTMP'
and    concurrent_process_id = 
      ( select max(concurrent_process_id) from fnd_env_context );

VALUE
--------------------------------------------------------------------------------
/d01/oracle/VIS/inst/apps/VIS_demo/appltmp

NB: These queries assume your concurrent managers are running!

Catch ya!
