Distributed Database + DB13 + SAPXPG + Standalone Gateway

Question

Hi All,
I knew this question has been asked and answered but i still couldn't find the concrete solution. Any advise is mostly welcome.
I've installed Distributed Database on Solaris and CI on Solaris as well. Due to security reason and policies, our customer stop us from using RSH.
I've installed standalone gateway in Distributed Database with System Name EGW, system number 20. My SAP and DB name is AEP.
gwrd is started using egwadm. TCP_IP connection SAPXPG_DBDEST_DBHOSTNAME works fine, however when i kick off checkDB in DB13, i got the below error:
"> Function: BtcXpgPanicCan't exec external program (No such file or directory)"
Have i miss out something? Do i need to add any ENV to egwadm or edit the SAPXPG program?
fyi, br* and SAPXPG authorization are all set correctly in /sapmnt/AEP/exe. Env for AEPadm in CI is identical to AEPadm in DB server.
Please advise.
Thanks,
Nicholas Chang.

Hi All,
Since there's no SAP Note explaining how to setup standalone gateway in UNIX env and incorporate for brtools to work in distribtuted system. I'll summarize the resolution here:
1) Install GW in database server
2) update the GW start profile with below value:
BGW = Gateway's SID.
SETENV_00 = LD_LIBRARY_PATH=$(DIR_LIBRARY):%(LD_LIBRARY_PATH)
SETENV_01 = SHLIB_PATH=$(DIR_LIBRARY):%(SHLIB_PATH)
SETENV_02 = LIBPATH=$(DIR_LIBRARY):%(LIBPATH)
SETENV_03 = ORACLE_SID=SID
SETENV_04 = SAPDATA_HOME=/oracle/
SIDSETENV_05 = PATH=$PATH:/home/BGWadm:/usr/sap/SID/SYS/exe/run:/usr/bin:.:/usr/ccs/bin:/usr/ucb:/oracle/SID/112_64/bin
3) update BGWadm env profile - sapenv_HOSTNAME.csh
setenv SAPDATA_HOME /oracle/SID
setenv ORACLE_SID   SID
setenv PATH /home/bgw:/usr/sap/BGW/SYS/exe/run:/usr/bin:.:/usr/ccs/bin:/usr/ucb:/oracle/SID112_64/bin
setenv ORACLE_HOME /oracle/SID/112_64
setenv USER bgwadm
setenv dbs_ora_schema SAPSR3
setenv NLS_LANG AMERICAN_AMERICA.UTF8
setenv DB_SID SID
setenv dbs_ora_tnsname SID
setenv dbms_type ORA
setenv LD_LIBRARY_PATH /usr/sap/SID/SYS/exe/run:/oracle/SID/112_64/lib
setenv DIR_LIBRARY /usr/sap/SID/SYS/exe/run
4) copy br* to gateway's /sapmnt/SID/exe/ and ensure 4775 is granted
5)Create the special OPS$ setting to allow BGWADM to log into the database.  use the script below .  Log in as oraSID to run this on DB host via SQLPLUS (connect /as sysdba)
CREATE USER "OPS$BGWADM" DEFAULT TABLESPACE PSAPSR3USR
TEMPORARY TABLESPACE PSAPTEMP IDENTIFIED EXTERNALLY;
grant unlimited tablespace to "OPS$EGWADM" with admin option;
grant connect to "OPS$BGWADM" with admin option;
grant resource to "OPS$BGWADM" with admin option;
grant connect to "OPS$BGWADM" with admin option;
grant resource to "OPS$BGWADM" with admin option;
grant sapdba   to "OPS$BGWADM" with admin option;
CREATE TABLE "OPS$BGWADM".SAPUSER
(USERID VARCHAR2(256), PASSWD VARCHAR2(256));
INSERT INTO "OPS$BGWADM".SAPUSER VALUES ('SAPSR3',
'your_password');
6) stop gateway and kill gateway sapstartsrv
7) start gateway
8) in CI - SM59 - TCP_IP -> SAPXPG_HOSTNAME_DB -> ensure gateway host is points to DB server and sapgw is the system number for DB Gateway
9) test checkDB in db13.
Cheers,
Thanks,
