Using SYS_retries property in ESS job definition- SOA Suite 12.2.1.0.0

In this post we will see how to use retry in ESS job definitions.

ESS provides the retry functionality through parameter SYS_retries and retry will happens when ever any system or other error occurs during the processing of ESS job request. By default, the value is set to 0 and it mean no retries will be done.

We can set the value of this property while submitting the request or while creating the job definition .

essretry1

After setting the property in Submit job definition , you will find the value like below.

Once after submitting the job we can see the no of retries in search job request window like below.

B2B Listening Channel not Pulling Files from SFTP Folder After server downtime.

Issue –> B2B listening channel is not pulling the files from SFTP server after downtime.

Error –> Closing Client.

Cause –> B2B has automatically disabled the listening channel because it is not able to reconnect to the SFTP server.

If an SFTP server goes down, B2B makes 3 attempts to reconnect. If unsuccessful, the listening channel is disabled, and remains disabled even after the SFTP server is brought back up.

Solution –> 

The fix introduces new property b2b.listening_channels.continue_reconnect. When it is set to true (default is false) B2B will make continuous attempts to reconnect to the SFTP server.

Set the parameter using the following instructions:

1) Log on to the EM Console.
2) Go to SOA -> soa-infra (right-mouse click) -> SOA Administration -> B2B Server Properties -> More B2B Configuration Properties.
3) Click Operations tab and then addProperty.
4) Add the property as follows, including comments (optional):

key: b2b.listening_channels.continue_reconnect
value: true
comments: continuous SFTP server reconnection attempts

5) Click Invoke to set the property and Return.
6) Restart the SOA server to make B2B aware of the new property setting.

Expand the Server:soa_server1 node.

Expand the B2BConfig node.

Click the b2b MBean.

The properties of the MBean are displayed in the right pane.

Click the Operations tab.

In Operations window click on Addproperty .

Provide the value for key as –> b2b.HAInstance

Provide the value for value as –> true

And click on Invoke button on the right hand side. For return from that page click on Return.

If you have 2 servers in the cluster , please add the property in both nodes.
