Tom ------- Forwarded Message Date: Mon, 11 Dec 2000 11:33:45 -0700 From: Anne Wilson <address@hidden> To: address@hidden, address@hidden, address@hidden, address@hidden, address@hidden cc: address@hidden, address@hidden, address@hidden, address@hidden, address@hidden Subject: LDM V5.1.3 Hello again to the IDD top level ingest sites, Version 5.1.3 of the LDM is available. Two changes are of particular interest to top level ingest sites. One is a change to pqing that will put radar products under the NEXRAD feed types. The other is a change in the signature calculation that improves duplicate detection. IMPORTANT ITEM #1: You must make a new queue before starting this version. IMPORTANT ITEM #2: Before restarting the LDM, you must change your current invocation of pqing to include the -5 option, a flag that affects how the signature is calculated. In version 5.1.3 the signature calculation has been changed to skip a product's sequence number. This way products that are identical except for their sequence numbers will be considered duplicates. It is our goal to use this new method in the signature calculation. However, we must coordinate making this change so that all top level ingest sites make the change as simultaneously as possible. Otherwise, identical products being ingested by multiple sites will have different signatures. This could cause a large increase in the number of products. My hope is that all sites will be able to upgrade independently sometime during the next week, and once that is done we will all make a simultaneous change to our pqing invocations. In version 5.1.3 the -5 option tells pqing to calculate the signature the old way, using the sequence number. For most people this will mean changing the line in their ldmd.conf file that invokes pqing to include the -5 option, then stopping and restarting their LDM. Then, we must pick a time when, after upgrading, all top level ingest site simultaneously remove the -5 option from their pqing invocation. I would like to do this on Thursday, December 14 or Monday, December 18. PLEASE SEND ME EMAIL INDICATING THE TIMES YOU ARE ABLE TO MAKE THIS CHANGE. Z times would be greatly appreciated. The source code for version 5.1.3 is available at ftp://ftp.unidata.ucar.edu/pub/ldm5/ A binary version for Solaris 5.7 i86 is available at ftp://ftp.unidata.ucar.edu/pub/binary/sunos_5.7-i86pc/ Again, thank you for all your help and support in this effort. You are performing a great service to the community. Anne -- *************************************************** Anne Wilson UCAR Unidata Program address@hidden P.O.
