History from SQL Agent Jobs (SQL Server 2005) how can I able to see all available records from SQL Agent Jobs, because in SSMS is dispayed only reduced number of records
are these records stored in system databases, not only in plain log files
how can I get records generated by SQL Agent Jobs only
is this history settable,
You need msdb.dbo.sysjobhistory and a few JOINs of course to read the data

To change how SQL Server Agent uses this table, use this stored procedure with suitable values

EXEC msdb.dbo.sp_set_sqlagent_properties
    @jobhistory_max_rows = 1000,
    @jobhistory_max_rows_per_job = 100
