Issue/Introduction

What is the purpose of Datacom console command WRITE_PENDS_LOG_STABLE?

Environment

Release : 15.1

Component : CA DATACOM/DB

Resolution

WRITE_PENDS_LOG_STABLE  feature is documented here

(Optional) The WRITE_PENDS_LOG_STABLE command provides a path to cleaning all pended index and data area buffers by writing them to DASD. Once this task is completed, the log area is stabilized so that if the MUF were terminated, the following MUF execution (in particular, a Shadow MUF) will quickly enable with a short scan and redo process.

Also:  Note 1: There is never a requirement to execute this command.

Refer to the documentation for additional information.

Accounting is excluded so if accounting tables are open then you need to run ACCT SPILL to flush the accounting buffer.

Additional Information
