Buildserver/env:
================
setenv WD /storm2_work2/yvesz/asetraining/				Workdir, with "data","log" and interfaces
setenv SYBASE /remote/lnxcorona_bld2/yvestest/Ase/asecorona		Release location, the $DES of perl
setenv DSVR $SYBASE/$SYBASE_ASE/bin/diagserver				The boot server, diagserver can use gdb

Release link:
perl /calm/svr/sql/generic/tools/link_to_release.pl  $SRC $DES		perl script <releasepath> <destinationpath>


Create view and ccset for modify code:
======================================
calm -v asecoronabtrim_yvesz_vu						go into view of btrim
e2 create -qoff <Viewname>						only change code in local without checkin
e2 create <CR#>								
ct co -unres $DBMS/generic/source/dbcc/exec_dbcc.c			check out the code with unreserved, then can modify '$DBMS/generic/source/dbcc/exec_dbcc.c'	
ct unres $DBMS/generic/source/dbcc/exec_dbcc.c				change the status of '$DBMS/generic/source/dbcc/exec_dbcc.c' to unreserve
ct help | tee <ct_help>							list ct commands both on screen and <ct_help> file
ct lsh -nco $DBMS/generic/source/dbcc/exec_dbcc.c |tee his		show the change history of '$DBMS/generic/source/dbcc/exec_dbcc.c' and put into his file

Gdb mode: for debug program in linux:
=====================================
gdb									come into a matched view and for diagserver mode
attach <No.>								attach ps of diagserver
b <func>								break point at the function
b <file.c>:<line No.>							break point at the line No. of file.c
b ex_imminent								go to the hang place of dbcc 2901
watch <var/*addr>							break when var/*addr's value changed
info b									show break point details
disa/ena <No.x>								disable/enable the No.x breakpoint
c									continue to next break point
n									next step
s									go into the function
p <var>									print var value
set <var> = 0								set var value = 0
enter									repeat lastest command
bt 									show the stack traces detail. backtrace 2/-2(first/last 2)
up/down <No.x>								go up/down x traces to the func
frame <No.x>								go to No.x trace's func
list									show code below
focus									show code window up
x/100c sqlbuf								print 100 chars of sqlbuf structure


Sybmon mode: look data structure of ASE
=======================================
cd $SYBASE								must come into SYBASE dir
$DSVR -X -Pquine							find the build server
cat .									show sth 
attach 0								attach the bootase(the No. is 0)
who									details of sessions with spid
help 									show commands in sybmon mode
buffer/page/keptbufs/log/recvbuf/locks ?				show patten of buffer/page/keptbufs/log/recvbuf/locks commands
page 2396 1 4								like dbcc page(1,2396,4)								
recvbuf <spid>
locks <spid>
stack <spid>

Dbcc: Database consystem check(session)
dbcc traceon(3604)							show details log in screen
dbcc traceon(2901)							look stack and stay hang 


Build codes after modified code:
=================================
setenv SSBUILT $DES							choose <destinationpath> for SSBUILT(full build)
~jih/bin/build1.sh > & build.out &					excute build script, then information(include errorlogs) put into build.out, back ground
tail -f build.out							update show build.out's tail					
or use barrier new session of the CR & view				recommand this easy way


Show information:
=================
h									show history commands details
!<No.command>								execute <No.command> command in history list
ps x									show processes details
kill -9 <No.pid>							kill the <No.pid> process with force


calm view:
==========
ct lsh -nco $DBMS/generic/source/dbcc/exec_dbcc.c > exec_dbcc.his 	show the modified history log of '$DBMS/generic/source/dbcc/exec_dbcc.c' and write into 'exec_dbcc.his'
ct lsh -nco $DBMS/generic/source/dbcc/exec_dbcc.c | less(head,tail)
