DESCRIPTION: Customer is using a primary and backup naming agent on two groups (nimi=11000 & nimi2=11100) on the same Alpha V7.3-2 (attached dmq$init.4000_11000) %NAM **************** Naming Agent Section ******************** NA_GROUP 11000 NA_GROUP 11100 %EOS It appears from a third group (11001) that the Naming Agent is switching from primary to backup endlessly; for instance (attached dmq$evl_4000_11001.log): COM_SERVER 15-MAR-2007 18:58:15.75 E Naming agent comm error, switch to naming agent in group 11100 COM_SERVER 15-MAR-2007 18:58:18.92 E Naming agent comm error, switch to naming agent in group 11000 COM_SERVER 15-MAR-2007 18:58:19.30 E Naming agent comm error, switch to naming agent in group 11100 ... Setting traces on NA_SERVER (& COM_SERVER) shows up that (attached dmq$evl_4000_11000.log): NA_SERVER 1-JUN-2007 09:18:11.26 I open_namespace_file: opened namespace file /DMQ$DISK/DMQ$V50/dmqns/<NAMESPACE>.dnf NA_SERVER 1-JUN-2007 09:18:11.28 I close_namespace_file: /DMQ$DISK/DMQ$V50/dmqns/k<NAMESPACE>.DNF NA_SERVER 1-JUN-2007 09:18:11.28 I close status = 0 NA_SERVER 1-JUN-2007 09:18:11.28 I Namespace entry does not exist and equivalent for other group (attached dmq$evl_4000_11100.log): NA_SERVER 1-JUN-2007 09:34:37.41 I open_namespace_file: opened namespace file /DMQ$DISK/DMQ$V50/NIMI2/DMQNS/<NAMESPACE>.dnf NA_SERVER 1-JUN-2007 09:34:37.44 I close_namespace_file: /DMQ$DISK/DMQ$V50/NIMI2/DMQNS/<NAMESPACE>.DNF NA_SERVER 1-JUN-2007 09:34:37.44 I close status = 0 NA_SERVER 1-JUN-2007 09:34:37.44 I Namespace entry does not exist Attached NADIR_protection.txt (result of $ dir dmq$disk:['f$trnlnm("dmq$root")'.dmqns...]/sec) clearly shows that for NIMI group, file exists: DISK$SYSDISK:[DMQ$V50.DMQNS.].DNF;1 with a standard protection. Trying to reproduce on FRVMS02 upon email received (on 06/04/2007 02:21:50 AM), DEFAULT_NAMESPACE_PATH definition from the DMQ$INIT.TXT file has been commented, and only use of Dmq$user:Dmq$boot.com: $ dmq_lnm DMQNS_DEVICE dmq$disk:[''.DMQNS] Several tests on DMQNS_DEFAULTPATH ("/<BUSID>/", "/<BUSID>/NAMESPACE", /<BUSID>/NAMESPACE ...) have not allowed to create the DNF file, still hitting on error below (using Manager Utility - NA LA) hence blocking reproduction. "file specification syntax error %NONAME-?-NOMSG, Message number FFFFFFF6" Questions: 1. How is normally created the DNF file and if corrupted/deleted how to re-create it? 2. It seems that problem is laying around DNF name which is case sensitive, but looks like converted in lowercase if used in Dmq$Init_File? CONFIGURATION: MSQ 5.0 (VMS)
