    Tuxedo load balance between Master/Slave

    874578
      Hi ALL,

      We have the setup like master/slave configuration for load balancing purpose. For this we have two groups, say G1(Master node) and G2 (Slave Node), having the same server ("SCBPPr") advertising the same service (single), say "ReqA". UBBCONFIG files for load balance (config copied few part) setup are as follows.
      ----
      # MULTI DOMAIN template
      *RESOURCES
      DOMAINID MA
      MASTER M_A,M_B
      MODEL MP
      OPTIONS LAN,MIGRATE
      LDBAL Y

      *MACHINES
      HOSTA LMID=M_A
      MAXWSCLIENTS=1500
      CMPLIMIT="50000,MAXLONG"
      APPDIR="....."
      TUXCONFIG="..../config/TUXCONFIG"
      TUXDIR="/opt/tuxedo/tuxedo9.1"
      ULOGPFX="..../logs/ULOG"

      HOSTB LMID=M_B
      MAXWSCLIENTS=1500
      CMPLIMIT="50000,MAXLONG"
      APPDIR="....."
      TUXCONFIG="..../config/TUXCONFIG"
      TUXDIR="/opt/tuxedo/tuxedo9.1"
      ULOGPFX="..../logs/ULOG"
      *GROUPS
      G1 LMID=M_A,M_B GRPNO=34 OPENINFO=NONE
      G2 LMID=M_B,M_A GRPNO=35 OPENINFO=NONE
      *SERVERS
      DEFAULT: RESTART=Y REPLYQ=Y GRACE=0 MAXGEN=100
      ################# NODE A TUXEDO SERVERS ################
      SCBPPr
      SRVGRP=G1
      SRVID=1600
      MIN=24
      MAX=24
      MAXGEN=225
      RQADDR="GBP1"
      CLOPT="-p 1,900:2,5 -o ../logs/A.out -e ../logs/B.stat -r config=SCBP"

      ################# NODE B TUXEDO SERVERS ################
      SCBPPr
      SRVGRP=G2
      SRVID=10600
      MIN=24
      MAX=24
      MAXGEN=225
      RQADDR="GBP2"
      CLOPT="-p 1,900:2,5 -o ../logs/A.out -e ../logs/B.stat -r config=SCBP"
      -------

      We are facing issue in load distribution, as per tuxedo report (txrpt) from both nodes we can see that for service "ReqA" load on Node A is always greater (too much) than the load on Node B.
      Let me know what need to be add or alter in ubbconfig file.

      Thanks & regards,
      Pras
