Summary :
This SAP Note addresses transaction terminations due to overflows in the SAP paging file, particularly under heavy use of ABAP EXTRACT statements. The terminations are flagged by SYSTEM_NO_MORE_PAGING, EXTRACT_NO_MORE_PAGING, and MEMORY_NO_MORE_PAGING errors. These issues primarily affect special applications where the pre-set paging file size is inadequate. The recommended fix involves adjusting the profile parameter 'rdisp/PG_MAXFS' to increase server paging area. Limitations on 32-bit systems restrict the paging file size to 2GB. On 64-bit systems, this limitation does not apply if the file system supports larger files. The note also covers the settings for roll files and shared memory configurations affecting roll buffer and paging buffer, with adjustments recommended based on system architecture and kernel versions.
