SAP System Copy/Migration Tools

[AtulKumarJain]

Migration Tool
R3LDCTL
	Unloads ABAP dictionary from database
	Create tables index*.STR(STRUCTURE file)& DDL<DBS>.TPL
	DDL command temp lock
R3SZCHK
	Compute size of ABAP tables and indexes for the target database
	compute the ABAP-related size for the target database
	Create extent files *.EXT & target DBsize file DBSIZE.XML
R3LOAD
	Unloads|loads ABAP table data into the database
	Create.TSK
SMIGR_CREATE_DDL
	Generate database-specific DDL statements for Non-standard database objects of the ABAP dictionary (Mainly BW objects)
	Create <TABART>.SQL & SQLFILES.LST
	R3LDCTL ,R3SZCHK and R3LOAD are SAP System dependent
RS_BW_POST_MIGRATION
	Post system copy activities for non-standard DB objects in the ABAP dictionary
JLOAD
	Unloads|load Java dictionary structure and table data from to database
JSIZECHECK
	Compute the JAVA web AS-related size for the target database

Support tools for ABAP system copy
		Package splitter
			Splits R3load *.STR and *.EXT files to reduce export and import times
		Table Splitter
			computes "where" condition to allow multiple R3loads running on a single table during export/import
			Type R3TA - DB independent
			PL/SQL - Only for Oracle
		MIGCHEK(Migration Checker)
			Checks the existence of R3load import logs and verifies import task files
		MIG MON
			Allow advanced control of the R3load export/import process
			Automates dump shipping b/w sources/target system
			Supports parallel unload/load processing
			MIGMON and MIGTIME are JAVA-based tools & and release independent
		DISTMON (Distribution Monitor)
			Used to run multiple migration monitors distributed over different application server
		MIGTIME
			Analyzes export and import run times from R3load files

Support tools for JAVA system copy
		JPKGCTL
			Unloads JAVA dictionary information from the database
			JLOAD package splitting
			JLOAD table splitting
		JMIGMON
			Allows advanced control of the JLOAD export and import process
			Support parallel unload/load processing
		JMIGTIME	Analyses export and import run times from JLOAD log files
