DB compact error

Question

I was able to compact a large (>10GB) BDB using db_compact, and then I decided to compact again, to see what effect it had. I get this exception each time when using version 4.6.21:
java.lang.IllegalArgumentException: Invalid argument: DB_ENV->log_put: record larger than maximum file size (18094568 > 10485760)
at com.sleepycat.db.internal.db_javaJNI.Db_compact(Native Method)
at com.sleepycat.db.internal.Db.compact(Db.java:277)
at com.sleepycat.db.Database.compact(Database.java:66)
I could try to see if increasing the max log file size will help, but how I can I be certain that the log_put call won't exceed that size?

Answer 1

try this and see if it solves,
also, Emp_name data type is int. it should be varchar.
I suspect the reason is because you already have some data in student table but you identity seeds were not updated and hence it is trying to insert a row with emp_id value that already exists.and hence the primary key violation. also, your table DDL did
not really have an primary key but it would still error since you are inserting duplicate row in the identity column.
so, try resetting the identity seed value to the max(emp_id) in the table.
select max(Emp_ID) from  student
--use the output of the above statement
DBCC CHECKIDENT ('Student', RESEED,<<--use the output of the above statement-->>)
--your max(emp_id) should match with last_value column in the below( do not if this query would run in compact DB though)
select seed_value,increment_value,last_value from sys.identity_columns where object_id=object_id('Student')
now, try your insert.
Hope it Helps!!
