Problembeschreibung: | |
When AUTHENTICATION on the database server is set to DATA_ENCRYPT, any data transferred between the server and the client is encrypted. It was found that, with DATA_ENCRYPT DB2 LUW client sometimes fails to parse the query result, and returns SQL0902C. The size of the communication buffer is controlled by ASLHEAPSZ for local clients. For remote client at least a 128K buffer is allocated. The issue can be hit by both local and remote client. Here's the error message that will appear in db2diag.log. ==== 2013-03-06-11.29.11.620518+060 I174864A1392 LEVEL: Severe PID : 52232198 TID : 1 PROC : db2bp INSTANCE: db2inst1 NODE : 000 APPID : *N0.db2inst1.130306102052 EDUID : 1 FUNCTION: DB2 UDB, DRDA Application Requester, sqljrPostErrorProcessin probe:911 MESSAGE : ZRC=0x87360009=-2026504183=SQLJC_ERROR_BEOF "DATA DOES NOT EXIST" DIA8506C Unexpected end of file was reached.

JCC type 4 driver does not have this problem. The data in the server is never corrupted. The problem is only on the client that fails to parse the encrypted data. Any fix pack containing the fix for this problem must be applied to clients. | |

Local-Fix: | |
Local fix: If this problem occurs for a local connection, change the value of ASLHEAPSZ to any other value eg 8. For remote client, try changing FetchBufferSize greater than 128K. Also note that this problem is only applicable to DATA_ENCRYPT. One may choose to change AUTHENTICATION on the server side to some other value to work around it. | |
