Longer resource id is reqpured by compute node's resource as their id is '<hostname>_<nodename>'. DB2 creates a VARCHAR(70) for resource id when its length < 70. But DB2 can create a VARCHAR(n) for the resource id which has n(n>70) characters. This patch adds an option 'db2nosql_resource_id_maxlen'(default is 512) to allow user to adjust the value for their ENV. @DocImpact Change-Id: Ib58cfffb238d3b818831f0ccfe4659cfcf9c3c8a Closes-Bug: #1387532
