Thanks Melissa,<BR>
<BR>
We had spotted that already anyway and had already modified the new Deadline Monitor job to run not only in parallel but also process a maximum number of deadlines per run according to our own config setting should we wish.<BR><BR>We don't intend to run BPM either so we also avoided running the apparently duplicate Deadline job in SWU3 which actually kicks off RSWFSLSDLEX.<BR>

<P class=EC_MsoNormal><FONT face=Tahoma color=black size=3><SPAN style="FONT-SIZE: 12pt; COLOR: black; FONT-FAMILY: Tahoma">We just upgraded on Labor Day from 4.72 to ECC 6. We did have an issue with deadline monitoring jobs……the swwdhex job that previously ran consistently in a minute or less started running anywhere from 6 – 10 hours after the upgrade. Though it was scheduled every five minutes, each subsequent job would complete due to an active job running. OSS note 1092157 which indicates a design flaw in ECC 6.0 that actually processes the deadlines sequentially. Caused performance issues and something to keep in mind if you use a lot of wait steps and deadline monitoring……….</SPAN></FONT></P>

<P class=EC_MsoNormal style="MARGIN-BOTTOM: 12pt"><FONT face=Tahoma size=2><SPAN style="FONT-SIZE: 10pt; FONT-FAMILY: Tahoma">Rick,<BR> <BR>Similar picture here as it happens. No Java stack and no intention of using ABAP Classes or XML containers yet. But obviously the Workflow engine has been re-written with these things in mind so yes it's proving hard to comapre in terms of runtime like-for-like.<BR><BR>One thing is absolutely clear though: ECC 6 is a total memory hog by comparison. SAP have advised us to add on 50% more workspace needed to keep the same traffic flowing just to be sure and they don't seem to be far off the mark.<BR> <BR>We're running full scale volume tests with a Pre-Production environment starting this weekend (rehersal for the real upgrade) so I'll have more data to hand next week. I'm keeping my eye on some of our heavy workflow steps to see how long they take in the new environment. The only drawback is that we won't have exactly the same hardware to play with (4 app servers instead of 16) but at least I should be able to compare the same Workflow instances and spot any odd timing differences between 4.6c and ECC 6.<BR> <BR>I have taken the precaution to change all of our Workflow definitions to continue to use the 'old' BOR Object-based container (Structure Persistence) for now. You may want to do the same as the default setting (Compatibility) will seek to switch to the new XML container when the release version of the Workflow Header is later than 4.6c. But that's up to you of course :)<BR> <BR>I've not heard the '30% slower' figure by the way. My gut feel is that things are slightly slower all round, particularly deadlines, but I've not noticed that much of a delay, yet.<BR> <BR>Mike GT</SPAN></FONT></P>
