I deployed IA91 Broker Domain Data Store Support pac to my toolkit and Message Broker engine (Windows XP and 2003 Server).
1. I am using a compute node to add value to the environment
SET Environment.Variables.go[1].key = 'AAA';
SET Environment.Variables.go[1].data = 'BBB';
2. A CachePut node is right after the compute node and location of key and data are specified as:
Key = Environment.Variables.go.key
Data = Environment.Variables.go.data.
3. The message is sent to a queue (MQOutput).
Now, when I try to get the cache data from the other flow, I receive nothing.
Here is the flow design for retrieving cache data.
1. A MQInput node to start the flow.
2. A CacheGet node and location of key and data are specified as the
CachePut node.
3. A MQOutput node.
The message generated out from the retrieve flow doesn't have the cache data and I couldn't find anything available info from IBM that can help me to debug. Does anyone successfully implement a flow using CacheGet and CachePut node? If so, would you be able to explain how your flow put and get Cache data? |

I guess that you're using the latest version, because the earlier one didn't support the Environment trees.
There is a time-out for the Cache. What do you have it set to, and are you trying to Get the data within that time.
What are you setting, in EQSL, before the Cache Get.
I haven't tried changed my code to use the Environment, but it works great using the "data" tree.
Cheers,

EddieA,
I think it is the latest version because I checked the modified date of the zip file and it indicates it was updated in the earlier of this year.
I set "Life of data (millionsecond)" to 60000000. I did change to use the data tree "Root.XML.Main.body.Topic" and "Root.XML.Main.body.Name.FirstName", as the key and data. When I ran the flow in debug mode, I saw the message passed through the CachePut node and I am not sure it did cache the data. I also ran another flow (differene one) to try to retrieve the data but nothing shown. Do I need to specify anything using compute node prior or after CachePut or CacheGet node?
Thanks |

What's the 'scope of the cache', broker domain or execution group?
Are you sure the key to retrieve the cache is the same value as the key used to store it? |

JT,
The scope fo the cache is "execution group" on both CacheGet and CachePut nodes.
I think i got the problem fixed. There was a typo on my CacheGet "Location of Key".
Thank you both of you very very much.  |
