SAP MAXDB : Export/Import through Loader utility

by
Leave a comment

MAXDB Provides a powerful tool to perform Export/Import through Loader utility which is very useful in case of Heterogeneous System Copy.

There are some limitations to use Loadercli via command line as it require same versions on source & target to perform Export/Import.

If you are using different OS on source & target then Loadercli is not a good option as it’s very difficult to keep same versions on both side.

Loadercli will perform the same action smoothly as it works with MAXDB Studio where you can connect the both source & target DB’s & use same loadercli to perform export/import in the DB. You can export the entire SCHEMA or Tables from source & import the same in Target SCHEMA.

Loader requires SQL login to respective SCHEMA for export/import. You can do a SQL login by Right Click on DB & then SAPUSER SCHEMA name is visible. Expand the SAPUSER schema & right click on Schema or Tables —- select export. it will ask you some options & export the entire contents on your local PC.

The same loadercli can use for importing in Target Schema, do a SQL login in Target Schema, select SAPUSER schema & click on schema — Right Click & Import. Give the correct location & it will show the exported contents & you can select the options as requires & perform the import.

SAP official documentation –

I will share the screenshots of export/import in next post for more clarification.

How to fix MaxDB SDBSETUP issue

1. Download the MaxDB Database installation (MaxDB 7.9 – SP9 Build 05 Linux on x86_64 64bit) from Support Portal.

2. Unzip the Downloaded Zip MaxDB File.

3. Navigate to /sapdb/max/51052559_/DATA_UNITS/MAXDB_LINUX_X86_64

Run ./SDBSETUP

You will get the below error –

cannot load wxWidgets properly: Can’t load ‘/var/tmp/SDBLDLdvBNG/Wx.so’ for module Wx: libpangox-1.0.so.0: cannot open shared object file: No such file or directory at DynaLoader.pm line 230.
at SDB::Common::Require line 61

As per SAP Note – 2300026, There are some graphical libraries which are not supported in SLES11, SLES12 & RHEL7 versions. The SDBSETUP tool cannot be run on these operating systems.

SAP recommends you to use SDBINST / SDBUPD tool instead of SDBSETUP.

However there is a workaround where you can fix these libraries & run the graphical SDBSETUP.

I am referring here SLES 12 SP4 as my operating system.

If you run below command from installation directory, it will throw the error for libwx_gtk2-2.6.so.0, all other libraries are available. –

ldd -v WX.SO
linux-vdso.so.1 (0x00007fffabbb8000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f07571e0000)
libwx_gtk2-2.6.so.0 => not found
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f0756dff000)
libm.so.6 => /lib64/libm.so.6 (0x00007f0756b02000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f07568ea000)
libc.so.6 => /lib64/libc.so.6 (0x00007f0756545000)
/lib64/ld-linux-x86-64.so.2 (0x00007f0757748000)

Warning – Please do the changes as per your own RISK, SAP never recommend the same.

SDBSETUP will throw error on below 3 libraries (one by one)

1. libpangox-1.0.so.0
2. libpng.so.3
3. libtiff.so.3

Navigate to directory /usr/lib64 & copy the below libraries

cp libpangoxft-1.0.so.0 libpangox-1.0.so.0
cp libpng12.so.0 libpng.so.3
cp libtiff.so.5 libtiff.so.3

Navigate back to installation directory & run the command – ./SDBSETUP

cannot load wxWidgets properly: cannot open display

Now run the same command on VNCSERVER
