JCOClientConnection issue.

[Former Member]

Dear SDN Community,

I have created a custom WD java application which gets the data from R/3 system using RFCs. I have created the JCo connection pool named WD_MODELDATA_DEST with min connections 5 and max 50. Everything works fine. But after working with applications for some time, the pool gets exhuasted and I get the following error message.

Error while executing the function module Z_FRANCHISE_EXPENSE_LIST : Could not create JCOClientConnection for logical System: WD_MODELDATA_DEST - Model: class com.abp.cafe.model.TransferModel. The SSO ticket needed for authentication to WD_MODELDATA_DEST has expired. Close all applications and logon anew!

Can you please advise what are the precautions that I should take in my application to not arrive at this error message. Is this error message is because the pool gots exhausted. Please advice me here.

Thanks!

Surya.

Afi,

I am restarting the J2EE instance and that is fixing the problem that day. I get the same problem after 2,3 days. And I get this problem only in the beginning of the day and only once in a day but not every day. Any thoughts ??

Thanks!

Ruchit,

Thanks for the information. My application is running on 2004s SP12. The solution that was given in the SAP note : 771846 doesn't speak about 2004s. Can you please advice me.

P.S : The other note : 1013230 is not relavent for me as I am not using BIW here.

Thanks!

Surya.
