Error description
In 8.5.5.1 support was released to generate an FFDC log when sysprint buffer overflow events occur. This function is enabled by default. A private variable exists to disable this function. Request is to make this a public, documented variable. Additional symptoms: com.ibm.ejs.ras.NativeMessageOverflowException ***BUFFER OVERFLOW*** ffdc flood ffdc directory size entry count entries
Local fix
You can disable the logging of buffer overflow events by setting: private_bbor_enable_buffer_overflow_ffdc_logging to 0 Go to Environment---WebSphere Variables then set scope at cell/node as desired and then select new. Name: private_bbor_enable_buffer_overflow_ffdc_logging Value: 0
Problem summary
**************************************************************** * USERS AFFECTED: All users of IBM WebSphere Application * * Server V8.0 and V8.5 * **************************************************************** * PROBLEM DESCRIPTION: Unable to increase trace log * * buffer size. Unable to disable the * * creation of FFDC logs when a * * truncated trace is generated. * **************************************************************** * RECOMMENDATION: * **************************************************************** When traces are large, they maybe truncated if their size exceed internal trace buffer lengths. There is no documented setting to increase the size of the trace buffers to prevent traces from being truncated. When traces are truncated, FFDC logs are created to provide access to the full trace information. However, there is no documented setting to disable the creation of these FFDC logs. Note that when a trace is truncated a BUFFER_OVERFLOW string is appended to the end of the trace.
Problem conclusion
Environment variable ras_max_string_buffer_size was added to allow users to increase the size of WebSphere on z/OS' trace buffers. Environment variable ras_enable_buffer_overflow_ffdc_logging was added to allow users to disable creating FFDC log entries when BUFFER_OVERFLOW conditions take place. APAR PI27262 is currently targeted for inclusion in Fix Packs 8.0.0.11 and 8.5.5.5 WebSphere Application Server. In addition, sysroute APAR PI31128 in Fix Pack 7.0.0.37 will provide the fix in for WebSphere Application Server V7.0.
