![]() APAR status Closed as program error. Error description The SMF 120 subtype 6 J2EE container interval records are reporting incorrrect average response time values - usually higer than the client observes. The Activity records (SMF 120 subtype 5 records) appear to have accurate response time values. The response times are sometimes 20-50% higher than the values from the individual records, sometimes the are very similar.Local fix Problem summary **************************************************************** * USERS AFFECTED: All users of WebSphere Application Server * * V5.0 for z/OS * **************************************************************** * PROBLEM DESCRIPTION: The SMF 120 subtype 6 J2EE container * * interval records are reporting * * incorrect average response time values. * **************************************************************** * RECOMMENDATION: * **************************************************************** Code calculates the average after adding in each new time. The remainder is not added or subtracted so the average response time, SM120JM3, of large samples is not accurate. The SM120WIY field in the Servlet section of the SMF 120 Subtype 8 WebContainer interval record has the same problem.Problem conclusion Update the code to keep the total time and compute the average when writing the record. APAR PQ88991 is associated with SERVICE LEVEL W502011 of WebSphere Application Server V5.0 for z/OS.Temporary fix Comments
