PC_CLOUDTRADB_SOA_LNGZ_20151130\20151130092501\View_TenderPurchase_45.pre

     This is caused by the problem of reading permission of snapshot file , Two can be linked on the same machine sql server The service avoids this problem

    2. Cannot link to Subscriber “XXX”
    xxxx Unable to open and SQL Swever Link to
     And SQL Server A network related or instance specific error occurred while linking . Unable to find or access the server . Please check whether the instance name is correct and SQL Server Whether it is configured to allow remote links .

 View compatibility levels  
SELECT name, compatibility_level FROM sys.databases;
 Modify compatibility level  
ALTER DATABASE database_name
SET COMPATIBILITY_LEVEL = 100;

         Due to local installation SSMS Version is 2012 , Think it might be ssms Version results in , So use the command subscription . Create a subscription of the same version and generate a script , Specify as the following directory , NewSubscription The file is a subscription command , Modify the corresponding subscriber name @subscriber , Database name @destination_db , Release name @publication , user name @subscriber_login , password @subscriber_password
         First create the database at the subscriber she111 For accepting subscriptions . Implement snapshot publication and subscription through commands , Execute... At the publisher . Push subscription through publisher .
