I got tired of the licence management... Anyone to update it to mordern versions? .title liza - disable or enable license checking in VMS. ; ; Author: Me. ; Date : Late night. ; Year : Happy New. ; City : A big place with many houses. ; ; This utility disables or enables license checking on the running system by ; patching the routine EXE$GRANT_LICENSE in system space. The patch ; applied simply moves SS$_NORMAL to R0 and then returns. If license ; checking is to enabled, the original contents is restored (CHMK #^X5B). ; NOTE! there seems to have been a change between 5.2 and 5.3, in 5.3 ; the service number seems to be 5B for grant_license, and 5C for ; release_license. Under 5.2 however, release_license have 5B, wonder what ; grant_license have? ; ; 22-JUN-1992 Under V 5.5, exe$grant_license have number ^X64 !! ; ; When this is run, all system integrated products (SIP's) can be ; used immedeately. Layered products have to be installed first, ; but will then run properly. ; ; Abstract: ; ; Nothing special. We create a double mapping to the physical memory ; that contains the routine (since the original mapping is write-protected!). ; We give our mapping U:W - protection, then it's only to copy our patch ; there. ; ; Privileges needed to run: all ; ; ; Assemble: ; ; $MAC LIZA ; ; Link: ; ; $LINK LIZA,SYS$SYSTEM:SYS.STB/SELEC ; $psldef $prtdef syspag: .blkl 1 .blkl 1 syspfn: .blkl 1 retadr: .blkl 1 .blkl 1 sysver: .long sys$k_version cr=13 lf=10 vermsg1: .ascid <cr><lf>/System version mismatch - was not linked under this version of VMS ./ vermsg2: .ascid <cr><lf>/ Please relink:/<cr><lf><lf> vermsg3: .ascid " $LINK LIZA,SYS$SYSTEM:SYS.STB/SELECTIVE"<cr><lf><lf> dismsg: .ascid /%LMC-S-DISB, License checking successfully disabled./ enamsg: .ascid /%LMC-F-ENAB, License checking fatally enabled./ chkena: .ascid /%LMC-I-ENAB, License checking is currently enabled/ chkdis: .ascid /%LMC-I-DISB, License checking is currently disabled/ alr_ena: .ascid /%LMC-I-ENAB, License checking is already enabled/ alr_dis: .ascid /%LMC-I-DISB, License checking is already disabled/ disflg: .blkb 1 chkflg: .blkb 1 enaqual: .ascid /ENABLE/ chkqual: .ascid /CHECK/ silqual: .ascid /SILENT/ silflg: .blkb 1 .entry liza ^m<> ; ; Check current system version against the one we were linked under. ; cmpl g^sys$gl_version,sysver beql 5$ brw vermismatch 5$: movb #0,silflg ; assume nosilent pushaq silqual calls #1,g^cli$present blbc r0,6$ ; nosilent ok movb #1,silflg ; should be silent 6$: movb #1,disflg ; assume disable operation pushaq enaqual calls #1,g^cli$present ; is enable qualifier present? blbc r0,7$ ; nope movb #0,disflg ; wants to enable 7$: movb #0,chkflg ; assume not only check pushaq chkqual calls #1,g^cli$present blbc r0,9$ brw check_only 9$: cmpc3 #dis_license_pat_len,- ; check if checking is disabled exe$grant_license+2,- dis_license_pat beql is_disabled ; ; License checking is enabled.
