The cluster membership is derived at 'sqgen' > time which uses the existing node membership at a point in time. Since the > node membership of the cluster can change at any time after the 'sqgen' > invocation, the 'rmscheck.sql' input is by definition obsolete when the node > membership changes, i.e., nodes are added or deleted. > A different method for obtaining rms status must be implemented. > The current method generates the following contents of the 'rmschecl.sql' > input file: > cat rmscheck.sql > -- SQ config/utility file generated @ Thu Jun 01 14:00:58 2017 > prepare rms_check from select current_timestamp, > cast('Node' as varchar(5)), > cast(tokenstr('nodeId:', variable_info) as varchar(3)) node, > cast(tokenstr('Status:', variable_info) as varchar(10)) status > from table(statistics(null, ?)); > execute rms_check using 'RMS_CHECK=0' ; > execute rms_check using 'RMS_CHECK=1' ; -- This message was sent by Atlassian JIRA (v6.4.14#64029)
