Out-of-memory errors with reports that are run in interactive HTML format
Out-of-memory errors occur when you run a report in interactive HTML format. The errors do not occur when you run the report in other formats, such as PDF or saved HTML.
Out-of-memory errors occur in reports that contain many objects that require memory intensive processing, such as crosstabs and charts that are linked together with master-detail relationships. Running reports in interactive HTML can consume more memory than running reports in other formats. When a report is run in interactive HTML, data sets are kept in memory for all pages in the report. For report formats like PDF, data sets are released from memory after the report is rendered.
Under certain conditions, you can exceed the memory limitations of a 32-bit configuration of the Cognos® Analytics server report server component when you interact with an interactive HTML report. For example, scrolling through a report page by page or drilling up or drilling down can consume more memory and processing capacity in interactive HTML than in other output formats.
