Hi all,
I need to reduce the overall downtime of the db export process and I need to put the biggest db tables into separate packages.
How can I do this?
I have already modified the following files into <export_dir>/ABAP/DATA and <export_dir>/DB/ORA before to launch sapinst:
ddloadd.tab
*.STR
*.EXT
but unfortunately sapinst overwrites them with standard table distribution in the beginning of the export process.
I need also to define groups of packages, this is my "order_by.txt" file modified:
#PACKAGES NAME
SAPAPPL1
SAPSPROT
SAPDODS
SAPUSER5
SAPSDOCU
SAPSSRC
package group 1
[ SEQUENTIAL GROUP ]
jobNum = 4
#PACKAGES NAME
SAPAPPL2
SAPSSEXC
SAP0000
SAPUSER1
SAPDFACT
SAPDDIM
package group 2
[ SEQUENTIAL GROUP ]
jobNum = 4
#PACKAGES NAME
SAPAPPL0
SAPCLUST
SAPSPROT
SAPSLOAD
SAPSLEXC
SAPUSER
SAPSDIC
SAPPOOL
package group 3
[ SEQUENTIAL GROUP ]
jobNum = 4
It's correct?
Oracle DB versione:10.2.0.4
SAP kernel version: 7.01
Thanks in advance for your help.

Hello,
You can put the biggest db tables into separate packages according to size sort parameter in sapinst screen. Then 'import order' can be defined to select those bigger tables/packages to get imported 'first' as compared to a default import sequence.
Thanks

In order to change the default table distribution into the packages, I should modify the DB configuration files into <export_dir>, but soon after sapinst starts it overwrites with the default STR, EXT files.
Kind Regards,

Which files are you refering as "DB configuration files" ?

Hi Massimiliano,
where did you get the information that you have to modify DB config files in order to split STR files ?
As far as I know, you just need to select the proper option in SAPinst in order to achieve splitting of STR files.

Hi Massimiliano,
In order to reduce the downtime for DB export you have to perform Tablesplitting and change your database parameters accordingly.
For tablesplitting please follow the system copy guide (Preparation for Tablesplitting)
During export and Import modify the Oracle DB parameters as per the OSS Note 936441 - Oracle settings for R3load based
system copy

Hi,
Once you start sapinst ,let sapinst create the files as it does. Once sapinst stops and asks you to configure migmon and start it manually, delete all the files under <export_dir>/ABAP/DATA and <export_dir>/DB/ORA. Then carry on with the manual preparation wherein you generate STR files ,EXT files, split packages, generate WHR files and place them properly into the required directories.
The file order_by.txt should be like this
-
[Package-Group-1]
jobNum=1
SAPAPPL1
SAPAPPL2
[DYNPSOURCE]
jobNum=3
DYNPSOURCE-1
DYNPSOURCE-2
DYNPSOURCE-3
DYNPSOURCE-4

The names within brackets can be anything of your choice. The names in blue will be in square brackets.
