Build a Successful Archive Run Project Plan Archive jobs can run for a long time! Per 600 MB file, VBAK = 12 hours write, 16 hours delete, typical 4 files/quarter Items to consider Need 2 plans: Test and Production Resources: 2 wks/qrtr testing, 2 wks/qrtr executing Preplanned system down times Month end processing – system performance Other projects Contingency

Archive Again or Upgrade OSS Notes Check OSS regularly! Best way to search for notes “SARA”, “AOBJ” Error message Object name (ex SD_VBAK or VBAK) Program name (S3VBAKWR) “archive”, “archiving” Note 0102446 gives application areas for each archive object

Summary Use a project plan Right balance between performance and document flow integrity Small data set Review the process regularly
