We're running into a problem when trying to change SQLLiteSpeed backups clients to point to new TSM servers.
The old TSM servers are RHEL4 (on Intel) running TSM server 5.5.5.0 with efix for APAR IC71586. (kernel 2.6.9-89.0.11.ELsmp) The new TSM servers are RHEL5 (on Intel) running TSM server 5.5.5.0 with efix for APAR IC71586. (kernel 2.6.18-164.11.1.el5) We've made sure all the relevant values are set the same on the new servers, as on the old. (Management classes, disk storage pools, maxnummp, and everything displayed in "q opt" output on the TSM server.) The two SQLLiteSpeed clients we've used for testing are: GENERICSYSTEMNAME1 O/S: 2008 SQL version: - 10.0.4000.0 (2008 SP2) SQL litespeed version: - 5.0.2.0 TSM Client: 6.1.3.0 GENERICSYSTEMNAME2 O/S: 2003 SQL version: - 9.00.4207.00 (2005 SP3) SQL litespeed version:- 5.0.2.0 TSM Client: 6.1.3.0 We have gathered client side trace, and it appears to indicate the socket is being closed: 02/09/2011 15:07:51.192 : commtcp.cpp (2525): ANS1006I TCP/IP write error on socket = 9300, errno = 10053, reason : An established connection was aborted by the software in your host machine. 02/09/2011 15:07:51.192 : apisend.cpp (1175): Contents of verb (0x7) Data, length: 32768: 02/09/2011 15:07:51.192 : commtcp.cpp (2525): ANS1006I TCP/IP write error on socket = 4294967295, errno = 10038, reason : An operation was attempted on something that is not a socket. We have also gathered server side trace, but nothing unusual has been noted there. The symptom on the TSM server is that backup session stops making progress after a few minutes, and ultimately must be canceled to be cleaned up. We've opened a case with Tivoli support, and are working with the sysadmins of the TSM server. We're not making much progress. My hope is to jog the memory of the list and see if anyone has seen window size or other stack weirdness with RHEL 5 that is triggered by LiteSpeed backups.
