-----------------------------<snip>------------------------- I am a programmer. I don't know the about the log files created by mainframe OS/390 at the system level. I am very much interested to know all the log files created by mainframe. Can somebody teach me???. Thanks!!! ----------------------------<unsnip>-------------------------- That I know of, there are three "Log files".
1. The System Log, also known as SYSLOG, contains all the messages sent to any consoles, plus usually a few more that are usually suppressed from consoles. The wide variety of messages includes, but is not limited to, mount messages, job start and stop messages, LOGON and LOGOFF messages for TSO users, etc. SDSF will allow you to look at these messages in more detail. 2. The LOGREC dataset contains records for various hardware and some, but not all, software errors. These are processed for viewing and/or saving by the IFCEREP0 program. 3. By far the most extensive logs are the System Management Facility datasets. The wealth of information in SMF beggars description, but there are not defined IBM utilities for viewing all this data. RACF-related data can be examined by the RACF Report Writer and data can be offloaded and archived using the IFASMFDP program. If you're looking to use the MVS or z/OS logging mechanisms for logging information from your programs, I recommend using SMF. Operators get rather upset when messages that have little bearing to overall systems performance appear on consoles, increasing an already-cluttered message stream. I also "dis-recommend" any attempt to add your messages to LOGREC; IFCEREP0 won't know how to handle them or format them for reporting. Alternatively, you can always use a SYSOUT file or disk file of your own, and "roll your own" processing mechanisms. --- [This E-mail has been scanned for viruses by the YourNet Connection Virus system] [For more information, please go to http://www.ync.net/YourMAIL] ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
