This seems to be fine and you can still : 8. About CATALOG 8.1 Use ECS (If SYSPLEX) 8.2 VLF 9. Use LLA heavily 10. Verify LE options 11. Verify Compile options 12. If you can spend some money, BatchPipes 13. Verify if you can substitute SORT by MERGE in some applications 14. Verify if Cobol programs specify BLOCK CONTAINS ZERO RECORDS 15. Stripped Datasets
Atenciosamente / Regards / Saludos Ituriel do Nascimento Neto Banco Bradesco S/A 4254/DPCD Alphaville Engenharia de Software - Sistemas Operacionais Mainframes Tel: 55 11 4197-2021 Fax: 55 11 4197-2814 -----Mensagem original----- De: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] Em nome de Jason To Enviada em: quinta-feira, 27 de dezembro de 2007 06:50 Para: [email protected] Assunto: Batch Tuning We have been constantly improving our batch window by implementing the following available technologies: 1. SMS SMB and data compression on some of our VSAM files 2. System determined blocksizes on sequential files 3. BUFNO on some input files 4. Constantly improving our access to DB2 4.1 Add indices 4.2 Compress of big DB2 tables 4.3 Reorg of DB2 databases 5. Increase parallelism 6. Improve DFSORT performance 7. Improve application efficiencies We have basically improved the batch window after implementing all these, however, after some time, the batch starts to become longer again. My question is aside from these, any other thing we can do to implement to improve our batch further? TIA.
