I have been testing OF 3.5.2 and the monitoring plugin in combination with different DBMSs. SQL Server 2005 and HSQL are OK but Oracle XE and Oracle 9i have problems. The statistics web site is empty. I followed the instructions that I read under this and this discussion thread (truncated ofRRDs, changed JDBC drivers, copied the tables from an embedded db to Oracle) but without success.
The error message says that the maximum size for the BLOB in the ‘byte’ column has been exceeded. This message is repeated for all ten statistic categories. I am therefore thinking that Oracle’s BLOB handling causes fragmentation / truncates data or that a special configuration for the Oracle DBMS is required.
Does anyone have an idea how this can be solved?
