Management Central running but cannot open.

Management Central is running but when I try to open it I get "An unhandled win32 exception occurred in cwbunnav.exe" It opens a Visual Studio Just-In-Time debugger. Selecting Yes to debug doesn't work because the source is unavailable. Selecting No (and when exiting the debugger), the iNavigator terminates. So far every thing I've read leads me to believe I should be able to open it. We're on v5r3, my iSeries Access is v6r1. We tried this on 4 PC's (one at Access v5r3) with the same results.

    Your first step with any similar problem should lead to IBM i Access Service packs. Check your System i Access Properties through the PC's Start menu to verify version/release and 'Service level'. Download/install the appropriate service pack if your 'Service level' is more than a few months behind. I wouldn't quite trust iAccess 6.1 for a V5R3 system if I had a choice. There were a lot of networking changes between those, especially in V5R4. It should work fine if the service level is recent enough, but there's always chances for mismatches in odd problems. I'd try 6.1, but I wouldn't spend much time if I had iAccess V5R3 available. Download/install service packs for both of them. What OS version is on the PCs? (And how did you get iAccess 6.1 if your system is V5R3?) Tom

    I installed the latest service pack but that doesn't seem to have resolved the issue. I want to do some more checking next week before I go back iAccess 5.3. We were planning on going to V6R1 but found out last November that our JDE software won't migrate without some costly modifications so we are looking at that now. The OS on my PC is Windows XP Professional. I'm also responsible for some legacy Microsoft applications that won't run on Windows 7, though we're planning/working on those (i.e. re-write). Thanks and will post more later. Jim

    I run iAccess 6.1 on both WinXP Pro and Win2K Pro. I'm reasonably certain that I had no problems with MgtC nor with interactions with V5R3 systems, but the MgtC Central system was running on V5R4 or 6.1 (depending on configurations at the time). I don't think I ever had iAccess 6.1 on a PC while using MgtC Central on a V5R3 server. (Nor do I have the combination available now.) Has MgtC been working? Or are you just starting to look at using it? Tom

    I just started looking at MgtC in December and I believe I'm the only one to ever try it since no one else was aware of the issue - I just started here last June and don't know if anyone tried it before than. I also want to check the service pack on the PC at iAccess 5.3. Jim

    BTW, how certain are you that the V5R3 system's TCP/IP configuration is both compliant with RFCs and correct? Most TCP/IP apps still run without errors when configurations are not quite compliant, but MgtC does more complicated stuff that tends to push things past tolerances. Little details cause troubles that don't surface otherwise. Tom

    Before I posted this I did find some info about that issue (probably somewhere in this forum) and our TCP/IP configuration did match, though I believe it only listed some configuration options. That is an area I want to explore further (at least to learn more about TCP/IP). I haven't been able to get use of the PC at iAccess 5.3 to update the service pack yet, I may have to install it on mine for that test. FYI. The verify connection passes but I noticed the MgtC server is not using SSL. Also, I'm seeing this message in the joblog for QYPSJSVR. CPFB976 Management Central object list not retrieved. Detail: Could not retreive object list of type [com.ibm.mc.client.definition.McEndpointSystem]. I've seen it several times but haven't been able to track it down. Jim

    Have seen this before and was initially advised to remove all contraints from QMGTC* libraries and run the command CALL QSYS/QYPSSETUP PARM(V5R3M0) - which recreates files and constraints - worth a try - but that didn't resolve the fault. This was caused when many Q* libraries where restored on top of existing libraries resulting in files do be renamed with description like “Old name QAYDOBACK in lib..” Suggest running a qry over dspobdj of all files and looking for duplicate objects by the text description above. In this case deleting the many duplicate objects (000's) fixed the problem.

    Thanks for the input, I have checked some of the libraries and found one duplicate of QAYDOBACK, it's the only duplicated file I've found so far. However, getting rid of it didn't work, I ended and started the server but no change. Thanks Jim

    The presence of a duplicated MgtC file would have me being cautious. You might review this Object Damage Related thread in developerWorks for a somewhat more detailed description. I'd think that the whole series is reasonable just to be sure things may start fresh. Tom

    Finally getting back to this. That link you sent seems to have worked. I'm able to open MgtC now. I'm going to do more checking but I think it may be resolved. Thanks, Jim
