I apologize for posting a question that seems to have been asked numerous times on the internet, but I can't quite fix it for some reason.
I was trying to populate some tables using Oracle's magical sqldr
utility, but it throws an ORA-01775 error for some reason.
Everywhere I go on Google, people say something along the lines of: "Amateur, get your synonyms sorted out" (that was paraphrased) and that's nice and all, but I did not make any synonyms.
Here, the following does not work on my system:
SQLPLUS user/password
SQL>CREATE TABLE test (name varchar(10), id number);
SQL>exit
Then, I have a .ctl
file with the following contents:
load data
characterset utf16
infile *
append
into table test
(name,
id
)
begindata
"GURRR" 4567
Then I run this command:
sqlldr user@localhost/password control=/tmp/controlfiles/test.ctl
The result:
SQL*Loader-702: Internal error - ulndotvcol: OCIStmtExecute()
ORA-01775: looping chain of synonyms
Part of test.log:
Table TEST, loaded from every logical record.
Insert option in effect for this table: APPEND
Column Name Position Len Term Encl Datatype
------------------------------ ---------- ----- ---- ---- ---------------------
NAME FIRST 2 CHARACTER
ID NEXT 2 CHARACTER
SQL*Loader-702: Internal error - ulndotvcol: OCIStmtExecute()
ORA-01775: looping chain of synonyms
And, if I try to do a manual insert:
SQL> insert into test values ('aa', 56);
1 row created.
There is no problem.
So, yeah, I am stuck!
If it helps, I am using Oracle 11g XE on CentOS.
Thanks for the help guys, I appreciate it.
EDIT:
I kind of, sort of figured out part of the problem. The problem was that somewhere along the line, maybe during a failed load or something, Oracle had given itself corrupt views and synonyms.
The affected views were: GV_$LOADISTAT
, GV_$LOADPSTAT
, V_$LOADISTAT
and V_$LOADPSTAT
. I am not quite sure why the views got corrupt, but recompiling them resulted in compiled with errors
errors. The synonyms used in the queries themselves were corrupt, namely the gv$loadistat
, gv$loadpstat
, v$loadistat
and v$loadpstat
synonyms.
I wasn't sure about why this was happening and I didn't quite understand anything. So, I decided to drop the synonyms and recreate them. Unfortunately, I couldn't recreate them, as the view they pointed to (there is a bit of weird recursion going on here...) was corrupt. These views were the aforementioned GV_$LOADISTAT
and other views. In other words, the synonyms pointed to the views that used those synonyms. Talk about a looping chain.
So...I recreated the public synonyms but instead of specifying the view as GV_$LOADISTAT
, I specified them as sys.GV_$LOADISTAT
. e.g.
DROP PUBLIC synonym GV$LOADISTAT;
CREATE PUBLIC synonym GV$LOADISTAT for sys.GV_$LOADISTAT;
Then, I recreated the user views to point to those public synonyms.
CREATE OR REPLACE FORCE VIEW "USER"."GV_$LOADISTAT" ("INST_ID", "OWNER", "TABNAME", "INDEXNAME", "SUBNAME", "MESSAGE_NUM", "MESSAGE")
AS
SELECT "INST_ID",
"OWNER",
"TABNAME",
"INDEXNAME",
"SUBNAME",
"MESSAGE_NUM",
"MESSAGE"
FROM gv$loadistat;
That seemed to fix the views/synonyms. Yeah, it is a bit of a hack, but it somehow worked. Unfortunately, this was not enough to run SQL Loader. I got a table or view does not exist
error.
I tried granting more permissions to my regular user, but it didn't work. So, I gave up and ran SQL Loader as sysdba. It worked! It is not a good thing to do, but it is a development only system made for testing purposes, so, I didn't care.
