To rebuild a server with Oracle as the RM, you can simply use the CICS Server Build Tool buildartcics. For example:

buildartcics -r Oracle_XA -o ARTSTRN

For detailed information of this tool, see CICS Runtime Server Build Tool in the Oracle Tuxedo Application Runtime for CICS Reference Guide

Besides, the file makefile_sample is provided as an example to help you generate multiple CICS Runtime servers at a time:

1. Open the <ART_INSTALL_DIR>/Cics_RT/tools directory;
2. Set correct environment variables as required, such as “ORACLE_HOME”, “TUXDIR”, “KIXDIR”, and “COBDIR/COBOLITDIR”. For more information of each environment variable, see CICS Runtime Server Build Tool Tool in the Oracle Tuxedo Application Runtime for CICS Reference Guide
3. Make sure all the servers in "ALL_EXECUTABLES" target in makefile_smaple are exactly the targeted servers you need;
4. Run “gmake - f makefile_sample all”
