symbolic link error when exporting during heterogeneous system copy

[Former Member]

My enviroment is ECC6.0/Oracle 10.2.0.2/SUN Solaris 10 . I'm performing heterogeneous system copy to Oracle 10.2.0.2/AIX 6.1 enviroment.

I've succesfully exported & imported two systems ie DEV & Solutin Manager , but PRD system has an OS problem with symbolic links ie Number of symbolic links encountered during path name traversal exceeds MAXSYMLINKS

I want to export both ABAP & JAVA stack but only the java stack is getting picked.

Below is part of the resultng sapinst.log

Thanks

Hi,

In PRD system, u might have craeted many symbolic links in /oracle/PRD fileystem . This should be avoided. Symbolic link should not be created in /oracle/PRD ...

Please check why symbolic links are created and get help from System Operation team . Please becareful to unlink symbolic links that are created by non-SAP. Make sure to perform full offline backup .

Please get the help from Unix System Operation team. Also it does not makes any sense to increase value of Unix parameter for maximum symbolic links.

Regards
