I am doing this because I have created a backup of a schema SQL*Loader can load data by using either a convention path load, or a direct path load. I have set: EXCLUDE=REF_CONSTRAINT. I ran the SQL to see what's locked and, sure enough, I have a table locked. Oracle has a mechanism for efficient maintenance of indexes on direct path loads. dmp Next I worked on creating an SQL DDL script file for the indexes and constraints. EMPLOYEE' Import only the rows from an exported table without loading table any table definitions $ impdp Expdp/Impdp grants and constraints only. We need to restore data for schema tables only, without restoring triggers. * I have manually created the tables first. e Instead what I do is use the "SQLFILE" option of impdp with the "INCLUDE=INDEX" option to get the "CREATE INDEX" statements For example, here is a DataPump import command that I used recently to import only triggers and constraints from a DataPump export file that included all schema objects: impdp [username]/[password]@[db_alias] schemas=JIRA directory=DP_DUMP dumpfile=jira_prod. So, without the tables being in the mix the indexes were being For example, here is a DataPump import command that I used recently to import only triggers and constraints from a DataPump export file that included all schema objects: impdp [username]/[password]@[db_alias] schemas=JIRA directory=DP_DUMP dumpfile=jira_prod. log CONTENT=METADATA_ONLY TABLE_EXISTS_ACTION=SKIP 4) 다른 계정, 다른 Tablespace 로 변경하여 import 하기 # expdp system/password directory=temp_dir filesize=10G schemas=scott dumpfile=scott%U. sql to remove all references to indexes and constraints and partitions, leaving just the CREATE queries. Enable Constraints on Target But while doing step# 6, I got "ORA-02327: cannot create index on expression with datatype LOB" as there are LOB segments and looks like Oralce doesn't like Only specific object types can be named with a Name clause. But only one worker is active and creates the constraint-indexes one after the other. sql to build indexes(may be split in parts and run simultaneously) after patching IMPDB is able to create indexes concurrently Job "PECOPAI".

The Network Link parameter is used in Oracle’s Data Pump utility (expdp and impdp) to facilitate the export and import of data between databases over a network. dmp I am using Datapump import using database link to import an entire schema from another Server but it gives issues with constraints. Please let me know if the below given step will make import faster if we exclude indexes and constraints Steps Import schema excluding constraints,rf_constraints,indexes with metadata only $ impdp directory=datapump dumpfile=emp_bkp. EXCLUDE specifies objects to exclude, while INCLUDE focuses on objects to include. Tables are not being analyzed in both cases, however, it is still analyzing the indexes. On the one hand this makes sense because when I specify the 'INCLUDE:INDEX' according to the documentation that will 'exclude' all other data types, including tables I assume. It'd have to be done manually. e. This sequence prevents data Now I want to create indexes and RI constraints, but I'm struggling to get the correction options as if I impdp with content=metadata_only and table_exists_action=append (only way not to skip the table, or replace or truncate the table) then the import process ignores all metadata about the pre-existing tables, so I get no indexes created and no constraints added. How can I do this with impdp? I try it with "content=metadata_only," but when I say "table_exists_action=skip" and the tables all exists this option ignore also all triggers, indexes, constraints on this tables. This happens with both Datapump and conventional export/import tools. [Updated on: Sat, 25 September 2010 23:31] by Moderator.
