4 ;IHS/OIT/HMW Patch 1 added validity check for passed-in namespace
5 ; 7/20/2009: Release of patch to support GT.M WV/SMH
6 ; Changes:
7 ; Addition of XINETD and GTMLNX entry points for support of GT.M
8 ; Changes of W *-3 (which only works on Cache) to W !
9 ; 9/7/2010: Minor bug fixes and enhancements
10 ; In GTMLNX: Set process name
11 ; In GTMLNX: Time out based now on the Kernel Broker Timeout field
12 ; in kernel system parameters file
13 ; 12/12/2010: Minor bug fixes
14 ; ETRAP nows screens errors before logging them. If it is a network
15 ; write error, it's not logged to the Error Trap
16 ; Set Process Name crashed on Cache due to undefined IO("GT.M").
17 ; Now this is surrounded by $Get to prevent this error.
