SAPJCo - Reconnect Support

[Former Member]

Hi,

I have a application built with JCo that supports the Idoc Processing by external system.

This makes use of :

DestinationDataProvider and ServerDataProvider by registering them

as

com.sap.conn.jco.ext.Environment.registerDestinationDataProvider

com.sap.conn.jco.ext.Environment.registerServerDataProvider

respectively.

First created a JCoDestination object with DestinationDataProvider as following properties set

and a IDocRepository object created on this destination, but if network is down it give exception (which is obvious),

How we can internally force to try and reconnect (user defined no of attempts / time interval) till the network is available ?

// properties used for DestinationDataProvider

DestinationDataProvider.JCO_ASHOST,"<hostname>"

DestinationDataProvider.JCO_SYSNR,"<Sysno>"

DestinationDataProvider.JCO_CLIENT,"<client>"

DestinationDataProvider.JCO_USER,"<User>"

DestinationDataProvider.JCO_PASSWD,"<pwd>"

DestinationDataProvider.JCO_LANG,"EN"

DestinationDataProvider.JCO_POOL_CAPACITY,"5"

DestinationDataProvider.JCO_PEAK_LIMIT,"10"

DestinationDataProvider.JCO_DEST,"<destname>"

JCoDestination destination = JCoDestinationManager.getDestination(destinationName);

// below line of code give me exception mentioned below:

IDocRepository repository = destination.getRepository();

// ERROR  Thrown is

HI Yogesh,

Please check your connection string (please do SOP of your connection string).

Thanks,

Hi Yogesh,

this means that it is not possible to establish connectivity to that host from the host, on which JCo is used.

Best regards,

Markus

I think problem in

partner '<Host Address>' not reached

Please check in HostName is pinging or not in your system.

Hi,

this question is not related to the SAP Application Interface Framework. So I will move it Java Development.
