Home -> Community -> Usenet -> c.d.o.server -> EXP-00056, ORA-12638 & Scheduled nightly exports under Oracle 8.1.6 and Windows 2000 server SP2
Any help appreciated...
I have Oracle 8.1.6 running on Windows 2000 server SP2
I have written a batch file that will perform an export every night
(when executed from 'Scheduled Tasks') and when I manually execute the
batch file, it produces the desired result (generates an export of the
listed schema) but when I get the Windows 2000 Scheduler to run the
batch file that contains...
D:\Oracle\Ora81\BIN\EXP system/manager file=f:\exptest.dmp compress=n buffer=20971520 owner=owner1 log=filename.log
I get:
EXP-00056: ORACLE error 12638 encountered ORA-12638: Credential retrieval failed EXP-00000: Export terminated unsuccessfully
in filename.log
Naturally I am doing the export manually for now...
I have tried scheduling the EXP.EXE command directly (instead of
having it in a batch file). I have tried executing cmd.exe and passing the batch file to it I have tried executing cmd.exe and passing the exp command directly toit for execution.
Bearing in mind that the EXP parameters provide a system/syspasswd(@localhost - tried both) authentication string as well as a log=filename.log paramater (which is recognized and generates filename.log that contains the output included above) I cannot understand why this should work from explorer or the command line but not from scheduler...
I would prefer not to have to change SQLNET.AUTHENTICATION_SERVICES =
(NTS)
Thanks in advance
