I try to import a schema in my database 9i of copy which is a clone of the original from where I made the export 9i also and when trying to import the schema after many hours gives the following error:

IMP-00017: following statement failed with ORACLE error 3113: "DECLARE SREC DBMS_STATS.STATREC; BEGIN SREC.MINVAL := 'C20537'; SREC.MAXVA" "L := 'C23524'; SREC.EAVS := 0; SREC.CHVALS := NULL; SREC.NOVALS := DBMS_STA" "TS.NUMARRAY(454,455,....

IMP-00003: ORACLE error 3113 encountered
ORA-03113: end-of-file on communication channel
IMP-00000: Import terminated unsuccessfully

The exp command is:

exp system/nnnnn CONSISTENT=y OWNER=myschema FILE=/path/backup_schema.dmp log=/path/backup_schema.log BUFFER=30720

The imp command is:

imp system/nnnn FROMUSER=myschema TOUSER=myschema FILE=/ path/backup_schema.dmp LOG=/path/backup_schema.log BUFFER = 536870912

I have searched and can not find a solution to this problem.

  • Did you try to specify FULL=Y while importing data? If not, do so. I'm not saying that it'll help, but - won't cost much to test it, right?

ORA-03113 is a generic error encountered when your database server process was terminated with a critical error. You can find more details in the database alert log. I guess you will see an ORA-07445 error there.

As we do not know these details, all I see is that your error is related to importing statistics. I would try to run this import without importing statistics by specifying STATISTICS=none.


  • NONE

Do not import or recalculate the database optimizer statistics.

Then after the import you can gather statistics as needed.

  • Thank you very much for such a quick response, I'm really short of time in this task, I'll try that option and comment, again thank you very much Aug 21, 2018 at 13:27
  • I used the imp with indexes = n and it is importing much faster, the doubt that I now have is how to re-create all those indexes again since they are so many ... how can I import the indexes or recreate them ??? Aug 21, 2018 at 19:08

    @ArnaldoRaxach And how is it related to the original question? You can use the INDEXFILE option to generate the DDL statements for indexes in a seperate file: docs.oracle.com/cd/B10501_01/server.920/a96652/ch02.htm#1005500 Aug 22, 2018 at 13:47
