To create a shared library for the send data UOC routine:

1. Select the update information that is to be checked by the send data UOC routine.
2. Create the function for the send data UOC routine.
3. Compile and link the function for the send data UOC routine.

The compiling and linking procedures are explained for each OS.

If an unresolved link error occurs, specify all libraries required during linking.

(a) HP-UX Datareplicator

• UOC routine compilation
  

  cc -c +z -I/opt/hirdbds/include UOC-routine-source-filename[UOC-routine-source-filename]...

• Compilation of a UOC routine in an environment for the IPF version
  

  cc -c +z -Y -I/opt/hirdbds/include UOC-source-file-name[UOC-source-file-name]...

  -c: Object creation option.
  +z: Position-independent code creation option.
  -I: Directory that stores the header files provided by Datareplicator (always /opt/hirdbds/include). You can specify multiple directories if the UOC routine requires other header files.
  
• UOC routine linkage
  

  ld -b -o libhdesuoc.sl UOC-routine-object-filename[UOC-routine-object-filename]...

• Linkage of a UOC routine in an environment for the IPF version
  

  ld -b -o libhdesuoc.so UOC-object-file-name[UOC-object-file-name]...

(b) Solaris Datareplicator

• UOC routine compilation
  

  /opt/SUNWspro/bin/cc -c -KPIC -I/opt/hirdbds/include UOC-routine-source-filename[UOC-routine-source-filename]...

  -c: Object creation option.
  -KPIC: Position-independent code creation option.
  -I: Directory that stores the header files provided by Datareplicator (always /opt/hirdbds/include). You can specify multiple directories if the UOC routine requires other header files.
  
• UOC routine linkage
  

  /opt/SUNWspro/bin/cc -G -o libhdesuoc.so UOC-routine-object-filename[UOC-routine-object-filename]...

(c) AIX Datareplicator

• UOC routine compilation
  

  xlc -c -I /opt/hirdbds/include UOC-routine-source-file-name[UOC-routine-source-file-name]...

  -c: Object creation option
  -I: Directory that stores the header files provided by Datareplicator (always /opt/hirdbds/include). You can specify multiple directories if the UOC routine requires other header files.
  
• UOC routine linkage
  

  xlc -bM:SRE -bnoentry -bE:/opt/hirdbds/lib/libhdesuoc.exp -o libhdesuoc.a UOC-routine-object-file-name[UOC-routine-object-file-name]...

(d) Linux Datareplicator

• Compilation of a UOC routine in an environment for the 32-bit or IPF version
  

  gcc -c -fPIC -I/opt/hirdbds/include UOC-routine-source-file-name[UOC-routine-source-file-name]...

• UOC routine compilation in an environment for the EM64T version
  

  gcc -c -m32 -fPIC -I/opt/hirdbds/include UOC-source-file-name[UOC-source-file-name]...

  -c: Object creation option.
  -fPIC: Position-independent code creation option.
  -I: Directory that stores the header files provided by Datareplicator (always /opt/hirdbds/include). You can specify multiple directories if the UOC routine requires other header files.
  
• Linkage of a UOC routine in an environment for the 32-bit edition
  

  ld -G -o libhdscuoc.so UOC-routine-object-filename[UOC-routine-object-filename]...

• Linkage of a UOC routine in an environment for the IPF version
  

  gcc -shared -o libhdesuoc.so UOC-object-file-name[UOC-object-file-name]...

• Linkage of a UOC routine in an environment for the EM64T version
  

  gcc -m32 -shared -o libhdesuoc.so UOC-object-file-name[UOC-object-file-name]...

You can store a created send data UOC routine library in any directory. However, do not replace libhdesuoc.sl (libhdesuoc.s for the Solaris or Linux Datareplicator, and libhdesuoc.exp for AIX Datareplicator) under /opt/hirdbds/lib.

Before executing the UOC, you must specify the directory containing the send data UOC routine library (libhdesuoc.sl or libhdesuoc.so) in the node_shlibpath operand in the extraction system definition. If the send data UOC routine library is not found in the directory specified in the node_shlibpath operand, Datareplicator sends all update information.
