IOS runs in a combination of DIE and SRB code, except for error recovery routines running in an SIRB. So if it needs to write an error messages rather than just return an error could, it needs an RB to do a WTO. I don't know the exact process, and I suspect that it has changed since the last IOS logic manual IBM made available to us peons.

When we see hardware issues, I am asked if the messages seen in various LOGs, like Batch JobLogs, or CICS STC Joblogs, caused the job to fail I am trying to remember if there is specific information about that process. I seem to recall that IOS needs an IO Event to occur so it can write out the messages. And it is just a random event as to which JOBS/STCS might get these messages produced. I am fairly certain that these messages did not cause the job to fail. So if there is specific doc or link, I would appreciate the details For example, IEA491I. We know what to do about the message, just need to be able to supply our users with links or docs why it happened in their Job log Lizette Koehler statistics: A precise and logical method for stating a half-truth inaccurately ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
