Solution
Referring to SAP Note 2360165 – Error in JSplitterExportJ2EEDatabase step during Database Instance Export.
Method 1
- Remove all the 7.0x jar files from the sharedlib directory. The 7.0x JAR files can be identified by file timestamp.
- Once done, repeat the step again.
Method 2
- Download the CORETOOLS.SCA from the SAP portal and ensure the version is the same as the current CORETOOLS.SCA of your AS JAVA system.
- Backup the directory of /sltools/sharedlib/.
- Remove all files inside /sltools/sharedlib/ *.
- From the downloaded CORETOOLS.SCA, extract copytools.sda and sltools.sda into the /sltools/sharedlib/. Once done, repeat the step again.
