need help with Informix XA and Tuxedo.

Hi! We are having a problem with the combination of Informix XA 5.02.UC2 and IMC Tuxedo 4.2.1 (or Novell Tuxedo 4.2.2) on AIX 3.2.5. TMS builds properly, but when we try to tmboot() it, we get the following error in the ULOG : ------------ 180923.koala!test_TMS.40917: LIBTUX_CAT:262: std main starting 180924.koala!test_TMS.40917: LIBTUX_CAT:466: tpopen TPERMERR xa_open returned XAER_RMERR 180924.koala!test_TMS.40917: LIBTUX_CAT:250: fatal: tpsvrinit failed 180924.koala!test_TMS.29143: CMDTUX_CAT:455: TMSEROR: tpsvrdone can't find group TEST1 180924.koala!test_TMS.40917: CMDTUX_CAT:457: TMS tpsvrdone complete 180924.koala!tmboot.48340: CMDTUX_CAT:825: Process test_TMS at SITE1 failed wit h /T error (LIBTUX_CAT:36: resource manager failure) -------------- We have a customer who has the same version of Informix XA and IMC Tuxedo, and we download and use their TMS. When running "tmboot", that TMS is up but all servers build on our system do not come up. They all have "tpopen TPERMERR xa_open returned XAER_RMERR". We also tried Novell Tuxedo 4.2.2, it has the same problem. My questions are: (1) Does anyone have any ideas? (2) Is there a log of Informix XA events? How do we find out what XAER_RMERR actually occured? By the way, we got Tuxedo and Oracle 7 XA working fine. Thank you all in advance!
