Use

You are running a distributed system with an Oracle database on a standalone database server.

The Software Update Manager introduces the new file system structure (nuc/uc) on the primary application server instance. This is the case when the following information appears in the SAPupConsole.log file after the KX_SWITCH phase:

The tool will convert the kernel structure to the new platform dependant [n]uc/<platform> layout.

After the conversion to the new file system structure, the database might not find the database tools during the update anymore.

Procedure

If this error occurs, check the symbolic links on the database host after phase KX_SWITCH. If they are no longer valid, rebuild the file system structure under /usr/sap/<SID>/SYS/exe as follows:

• For Unicode systems:

  • lrwxrwxrwx. 1 <sid>adm sapsys <day> 7 <time> uc -> /sapmnt/<SID>/exe/uc

  • lrwxrwxrwx. 1 <sid>adm sapsys <day> 7 <time> dbg -> uc/<platform>

  • lrwxrwxrwx. 1 <sid>adm sapsys <day> 7 <time> uc -> run -> dbg

• For non-Unicode systems:

  • lrwxrwxrwx. 1 <sid>adm sapsys <day> 7 <time> nuc -> /sapmnt/<SID>/exe/nuc

  • lrwxrwxrwx. 1 <sid>adm sapsys <day> 7 <time> dbg -> nuc/<platform>

  • lrwxrwxrwx. 1 <sid>adm sapsys <day> 7 <time> uc -> run -> dbg
