ORA-39095: Dump file space has been exhausted

Problem Description
I ran my datapump export operation with the combination of multiple dumpfile arguments and filesize parameter but it fails with ORA-39095 as below.

maximsg@TIGER> $expdp maximsg/a dumpfile=d:parti1.dmp,e:parti2.dmp,c:resit%U.dmp filesize=188417 tablespaces=users

Note that both in first and second case same errors are return but they show various bytes in order of unable to allocate. In first case Unable to allocate 188416 bytes and in second case Unable to allocate 208896 bytes.

Cause of the Error
They are many cause for which ORA-39095 is fired.
1)If the summation of dumpfile sizes that is specified in the datapump parameters is less than total dumpfile size that produces then ORA-39095 returns. Like in the second case the filesize is specified as 200K and only one dumpfile is specified. So maximum dumpfile size that can be produced is no more than 200K. If dumpfile to be produced is greater than 100K then above error will return.

Note that %U specification for the dump file can expand up to 99 files.
If 99 files have been generated before the export has completed, it will again return the ORA-39095 error. If in the second case %U is specified then maximum dumpfile size can be 99*200K=19800K. If dumpfile to be produced is greater than 19800K then error will return.


2)Like in the first case the size of filesize is too small and hence the error returns. filesize is defined about 184K(188407 bytes). And in the error message it shows unable to allocate 184K(188407 bytes). The solutions is and extra block is needed. As with 4k (with standard block size 8k) a block is generated so 188K filesize will solve the problem.

Solution of the Error
1)Increase the total dumpfile number so that dump produced by export operation is lower than total dumpfile sizes that is specified in the expdp.
With the 'wildcard' specification (%U) the dump file can expand up to 99 files.

2)Use a bigger filesize value.

3)Another option is to use,
dumpfile=dmpdir1:part1_%U.dmp, dmpdir2:part2_%U.dmp, dmpdir3:part3_%U.dmp

ORA-04062: timestamp of procedure has been changed

Problem Description In the database I have created one procedure named a as below. create or replace procedure a(a number) as begin insert into t1 values(1); commit; end; / Now after creating database link using remote database machine whenever I access this procedure "A" it executes successfully and I get value "1" in table t1. Like below in example where orastdby_m is the database link, shaik is the schema name and value 1 is the argument value though argument value is not used in the procedure. SQL> exec shaik.a@orastdby_m(1); PL/SQL procedure successfully completed. Now in the source database machine I changed the procedure as below. Though you can change anything like any literal; adding space or remove space. I changed value to be inserted from 1 to 2. create or replace procedure a(a number) as begin insert into t1 values(2); commit; end; / Now in the other database whenever I execute the procedure using database link it throws error ORA-04062. But subseq...

ORA-00939: too many arguments -when case arguments exceed 255

Problem Description In all Oracle 10.1g and oracle 10.2.0.1, 10.2.0.2, 10.2.0.3 whenever there is more than 255 arguments inside CASE statements then following error is returned. ORA-00939: too many arguments for function But surprisingly on Oracle 9.2 database the same code does not return any error. Cause of the Problem As we see the same code return error in 10g but it is well on 9.2. In fact this is problem of oracle 9.2 that it does not return any error. It should return error if there is more than 255 arguments inside CASE statements. In oracle 9.2 this is bug number 2909927 and this bug is fixed in oracle 10.1 and 10.2. That's why in 10.2 and 10.1 error returns if arguments exceed 255. Up to Oracle 10.2.0.3 and earlier version, the arguments of CASE statement is limit to 255 and it does not support exceed over 255 and hence error return if it exceed. However in Oracle 10.2.0.4 and later the arguments limit of CASE statement has increased to 32767. Solution of the Problem Opt...

ORA-31655: no data or metadata objects selected for job

Problem Description You are going to do data pump export operation in order to export objects based on filtering via EXCLUDE or INCLUDE parameter of expdp. In this example you wanted tables 'ACCOUNT_GROUP','ADDRESS','AREA_GROUP' and all the tables starting with word CV(like 'CV', 'CV_EXPERIENCE', 'CV_EDUCATION' etc) Your parameter file is like below. userid=smilebd/a directory=d dumpfile=b.dmp include =TABLE:"IN('ACCOUNT_GROUP','ADDRESS','AREA_GROUP')" include =TABLE:"LIKE 'CV%' " And you invoke expdp as expdp parfile=d:\parfile.txt from command line. But it fails with below message on my windows PC. C:\>expdp parfile=d:\parfile.txt Export: Release 10.1.0.4.2 - Production on Thursday, 29 January, 2009 14:53 Copyright (c) 2003, Oracle.
