From: zigzagdna on 4 Apr 2010 15:01 I am using Oracle 11.1.0.7.1 on HP UNIX 11.0. I ma using expdp and find it extremely slow. However. Most of the waiting time is during metadata (see below) where it waits for several hours. When it starts exporting the rows, it progresses reasonably fast. Processing object type DATABASE_EXPORT/SCHEMA/TABLE/INDEX/DOMAIN_INDEX/ INDEX I have seen some threads on Metalink as well as on Google. All otf tem point to these problems in Oracle 10.2 expdp version, but I see same problem in Oracle 11.1.0.7.1 as well. A suggestion to exclude STAITISTICS has not helped me: expdp system/password directory=expdp_dir dumpfile=$BackupExportFile logfile=$TLOGFILE \ full=Y compression=all exclude=STATISTICS TRACE=480300 I have turned on expdp tracing and I see statements like following for various indexes and do not give me any clue to speed things up. KUPW:14:48:25.668: 1: Base Process info: 6122 and processing status: C and processing state: R KUPW:14:48:25.668: 1: new state: R KUPW:14:48:25.668: 1: new status: C KUPW:14:48:25.668: 1: In procedure BUILD_SUBNAME_LIST with INDEX:MAXDEMO71.CONTRACT_NDX2 KUPW:14:48:25.669: 1: In function NEXT_PO_NUMBER KUPW:14:48:25.669: 1: FORALL called. KUPW:14:48:25.676: 1: FORALL returned. KUPW:14:48:25.678: 1: DBMS_LOB.TRIM called. v_md_xml_clob KUPW:14:48:25.679: 1: DBMS_LOB.TRIM returned. KUPW:14:48:25.679: 1: DBMS_METADATA.FETCH_XML_CLOB called. Handle: 200001 Is ether anyway to speed expdp.
From: javor on 4 Apr 2010 15:30 Try if adding this parameter helps: VERSION=10.2.0.2 (you may need to remove compression parameter since it's not supported in 10.2). You can also try excluding index statistics exclude=index_statistics --- frmsrcurl: http://compgroups.net/comp.databases.oracle.server/expdp-is-painfully-slow

I cannot reduce version because I am using some partitioing fetaures which are only in 11.1. Problem seems to be doiman index (seraching on google). Does not look like Oracle has fixe dthis problem/bug in 11.1 even though problem was reported back in 10.x.
From: javor on 4 Apr 2010 17:49 There are multiple bugs related to datapump performance in 11.1. There are patches for some of them. * Look at Metalink Note 984167.1 * You can also try PSU 11.1.0.7.2 (it may have some related bugs fixed) --- frmsrcurl: http://compgroups.net/comp.databases.oracle.server/expdp-is-painfully-slow
