3200.0. "DDS entries disappered from the database" by VAXRIO::ABREU () Wed Apr 30 1997 01:10

Hi,


	I have a customer running Message Router V3.2 and they are a ws node.

	They are complaining that some dds local entries disappered from 
their database.They say that nobody deleted these entries and another 
curious thing is that these entries still exist in other ws nodes. So it
doesn't really look like someone has deleted these entries because if this had
happened , the delete operation would be propagated to the others ws nodes.

	Any idea of what could cause this ?

	Thanks .... Marcia

    No particular ideas, however I should point out that there ARE ways 
    to delete objects from a database that won't propogate to other nodes. 
    For example, MBMAN DELETE DDS SUB/.../RESTRICT allows you to do this.
    (typically used to remove stale copies of objects from WSnodes when
    the master copy has been lost from the owning node). 
    
    You could try rebuilding the AIF file; DDS can't find an object in the 
    PERMDB without an attribute pointer in the AIF file (except by DDSID).

    Hi Dave,
    
      They will try the rebuild if there is no other way. For now , they
    have some DDSIDs of entries that are missing. You told us that if DDS
    searchs by DDSids, it doesn't check the aif file so iI could make
    this search and see if  the entries are there. This would really show
    us if the rebuild is necessary or not but I didn't find any command to
    search entries by ddsid.
                    
    	Is there any way to do it? They want to execute the rebuild only if
    it is really necessary because their machine is on production and they
    are afraid that this could impact the performance they have now.
    
    Thanks .. Marcia

    Standard MBMAN doesn't support searching by DDSID. A 32 character 
    hexadecimal string isn't something most customers want to deal 
    with... However, if they are running MR V3.3A on VMS V6.1 or higher, 
    the MBMAN image in the XDDS (aka MAILbus Directory Migration Toolkit)
    kit does support some operations (SELECT and DELETE as I recall) by 
    DDSID. FYI, the kit has an "MBMAN subset only" installation option.
    
    There is also an obscure utility in the MR kit that can do it, but 
    it's undocumented and very tedious to use. Given that the primary RMS
    key of the PERM_DB file is the DDSID, with a little time and effort
    you could write yourself a little program or com file and try to 
    read the record by its key (but don't expect to be able to make any 
    sense out of the data, and DON'T do it while DDS is running).
