SAP Sybase ASE 15.7 Lock Summary

SAP Sybase ASE 15.7 Lock Summary

This non-SAP stored procedure provides a summary snapshot of locks on an ASE dataserver.

It combines:
Query from master..syslogshold
dbcc sqltext of oldest transaction
Query of master..sysprocesses for oldest transaction showing login name
Query of master..syslocks showing table name of locked objects
Query of master..sysprocesses showing login names showing time blocked if applicable
