Hi,
I think that the easiest way is use ESQL and XML -document to contain your properties.
1. Declare SHARED ROW variable, or better in this time called cached data tree, at schema level.
2. When flow starts check that variable contains properties
3. If not, populate variable with parse command from xml document read from what ever source( file, mq, db, ws) you choose.
4. Use properties when ever you need them from variable just like you can use Environment or other data trees.

| Use User Defined Properties on the BAR file rather than a separate properties file. |

HI,
You mean to say I have a flow like
MQInput Node --> compute node
My MQINput will contain XML data.
So in my ESQL I need to write
BROKER SCHEMA com....
declare Cachedata SHARED ROW
And in my module
if Cachedata IS FALSE then
set INputRoot=OutputRoot |

1. Declare SHARED ROW variable, or better in this time called cached data tree, at schema level.
Are you asking to declare the shared row variable as
BROKER SCHEMA com.schema.abc
declare Cachedata SHARED ROW;
2. When flow starts check that variable contains properties .
DO I need to use UDP to do this?
3. If not, populate variable with parse command from xml document read from what ever source( file, mq, db, ws) you choose.
Parse in the sense ?
4. Use properties when ever you need them from variable just like you can use Environment or other data trees?
HOw?
Please could you guide me on this. |
