When DB2 then tries to invoke z/OS USS BPX1IOC service to obtain security related information for the socket, the BPX1IOC service failed due to the missing xxxxDIST ACEE. this contact form

Resolving the problem Determine what timeout value has been configured on the firewall. We needed to increate IDACK from 30 to 50, MAXDBAT from 64 to 200 and CONDAT from 64 to 200 and CTHREADS from 130 to 200. This leads to various unexpected DSNL511I messages and other unpredictable symptoms that can occur as a result of unexpected socket close conditions that appear to be randomly generated. Message DSNL425I. .

There might not be any other reported problems being caused by these failures. Both servers are configured the same. In all 4 cases, the IP addresses appeared to be client workstations. The entire risk arising out of the use or performance of the sample code is borne by the user.

I don't know enough about DB2 Connect Server to say whether this is normal, but I just took a look at our MSTR message logs and found several instances of DSNL511I The condition appears to be prevalent relative to connections with remote DB2 for z/OS partners, and this is due to the use of DRDA two phase commit support which tends to Inner Exception Type: IBM.Data.DB2.DB2Exception ;Inner Exception Message: ERROR [08003] [IBM][CLI Driver] CLI0106E Connection is closed.

+ Ask a Question Need help? Problem conclusion DB2 has been changed to ensure that the ACEE associated with the xxxxDIST address space is never deleted during remote connection authentication processing.

In other words, the communication errors did not show the root cause, and actually it also spent me quite some time to identify the root cause problem. We are using DB2 Connect via a gateway which has 2 servers assigned to it.

A console dump taken while the problem is happening will show ASXBSENV has 0's for the ssidDIST address space. Symptoms may be unpredictable but the following symptoms have been observed at, either or both, the DB2 11 for z/OS server and remote (usually also DB2 for z/OS) requester partners: . We think our problem is load related - b/c we only encounter under productin load and more so on our busiest servers.

We typically receive one of these IBM.Data.DB2.DB2Exception messages: ERROR [40003] [IBM][CLI Driver] SQL30081N A communication error has been detected. As a result, the DB2 TCP/IP Listener task will wait indefinitely for this "non-existing" connection request.
