Active FCT

Use this page to view information and modify the status for an active File Control Table (FCT) resource.

Click DUMP to create and view dump information for this FCT.

Click FCT Fix Up to apply the Fix Up process to FCTs which point to catalog DSNs. Typically this happens automatically on first access, and once only. If a change is made to a catalog entry which is referred to by an FCT, this button enables you to force a Fix Up process to prevent run time divergence between the physical file's DCB information and that held in the live table(s).
