Chapter 1. IntroductionApplication Performance Analyzer displays messages in a format similar to thefollowing example:AJT0000WMessages were generated by yourcurrent request. You might enter aMESSAGES command to view them.Explanation: An error occurred while processing yourcurrent request. One or more messages were issued todescribe it. You can view them by entering theMESSAGES command on the ISPF command line.Operator response: Enter MESSAGES on thecommand line of the current display. Read the messageor messages that are listed and if necessary, take theactions indicated by the message(s).The message number format is AJTnnnnx where nnnn is numeric and x is one of the following letters:I (Informational)Information is furnishedW (Warning)Processing attempts to continueE (Error)Processing terminatesS (Severe)Application Performance Analyzer terminates Copyright IBM Corp. 2005, 20071

Chapter 2. Application Performance Analyzer MessagesThis chapter describes where Application Performance Analyzer for z/OSmessages are logged, and lists the message IDs and descriptions.The Application Performance Analyzer for z/OS started task logs informational,error and diagnostic messages to various JES destinations The contents of theseoutput files are described here by their ddnames:JESMSGLGAll critical messages will appear in JES Message Log. If the started taskfails to start successfully, look in JES Message Log for messages reportingthe failure.COMMANDSAny commands processed by the started task (external or internal) arelogged to this file. The command text is displayed here, as well anymessage associated with the command.LOGR, MAIN, LOAD, CMDP, CHKPEach of these represents a single subtask attached by the ApplicationPerformance Analyzer for z/OS started task and contains messages loggedby that task. These are primarily informational messages and duringnormal operations you need not be concerned with the contents of thesefiles. They can be useful during problem diagnosis.REQ#request number, DATWrequest number, ESDErequest number,HVXTrequest numberThe Application Performance Analyzer for z/OS started task will allocateup to four sysout data sets for each sampling request submitted by a user.These data sets have the following format:REQ#request numberDATWrequest numberESDErequest numberHVXTrequest numberWhere request number represents the sampling request number. These areprimarily informational messages and during normal operations you neednot be concerned with the contents of these files. They can be usefulduring problem diagnosis.REQ#request numberContain messages related to the sampling phase of a samplingrequest.DATWrequest numberContain messages related to the sample file creation phase of thesampling request.ESDErequest numberContain messages related to the load module analysis phase of thesampling request.HVXTrequest numberContain messages related to the SQL host variable name resolutionphase of the sampling request. This sysout is allocated when theDB2V Extractor is selected. Copyright IBM Corp. 2005, 20073
