Split a large table into multiple packages - R3load/MIGMON
We are in the process of reducing the export and import downtime for the UNICODE migration/Conversion.
In this process, we have identified couple of large tables which were taking long time to export and import by a single R3load process.
Step 1:> We ran the System Copy --> Export Preparation
Step 2:> System Copy --> Table Splitting Preparation
We have created a file with the large tables which are required to split into multiple packages and where able to create a total of 3 WHR files for the following table under DATA directory of main EXPORT directory.
SplitTables.txt (Name of the file used in the SAPINST)
Which means, we would like each of the above large tables to be exported using 2 R3load processes.
Step 3:> System Copy --> Database and Central Instance Export
During the SAPInst process at Split STR files screen , we have selected the option 'Split Predefined Tables' and select the file which has predefined tables.
When we started the export process, we haven't seen the above tables been processed by mutiple R3load processes.
They were exported by a Single R3load processes.
In the order_by.txt file, we have found the following entries...
# generated by SAPinst at: Sat Feb 24 08:33:39 GMT-0700 (Mountain
Standard Time) 2007
default package order: by name
We have selected a total of 20 parallel jobs.
Here my questions are:
a> what are we doing wrong here?
b> Is there a different way to specify/define a large table into multiple packages, so that they get exported by multiple R3load processes?
I really appreciate your response.
