3.6 Limitations and Known Issues
Oracle Tuxedo Application Runtime for IMS limitations and known issues are as follows:
- Only one input message from a terminal is allowed in a single transaction.
- Cannot switch to a terminal other than the originator.
- Only Message formatting option 1 is supported.
- Cannot deploy IMS Region in Tuxedo MP cluster using heterogeneous machines.
- Does support IMS default system MOD - DFSMO2 which is used when MOD does not specify both in the application program and the MID "nxt" field. ARTIMS displays the output message as plain text in the terminal, users first need to clear the terminal.
- Due to byte ordering differences between "big endian" and "little endian" architectures, when using 'Dynamic Attribute Modification' in COBOL programs you cannot specify a decimal integer for attribute bytes. It is s suggested to specify a hexadecimal value one byte at a time in attribute bytes.
