DPC configuration change procedure on ISUP platform

1. Backup procedure:
   Before the configuration change we recommend to make a full system backup to recover quickly OS + OCMP Software + OCMP Configuration if needed. If it’s not possible at least backup OCMP configuration which requires OS and OCMP software running properly, same for IPSTG. Those backup scripts provided maybe need some modifications depending on your OS and OCMP & IPSTG version.

chmod 755 ocmp4_4-config-backup.sh
For backup:
./ocmp4_4-config-backup.sh -backup /var (script name & -backup option & destination folder where files will be stored)
For restore:
./ocmp4_4-config-backup.sh -restore /var/20160331-114337 (script name & -restore option & destination folder where files are stored)

Same for IPSTG script

 

2.DPC change procedure: 

• Route the traffic to this platform
• Make appropriated changes as described below:

Modification at USP-M level:

o   /etc/opt/OC/SS7/Saved.SS7_Stack_1.conf.ref.xml

o   /etc/opt/OC/SS7/isup.app0.conf & /etc/opt/OC/SS7/isup.app1.conf are not needed as only Signaling is affected not Voice.

o   /etc/opt/OC/IPSTG/SS7_SAVE_CONFIG.DAT.SS7_Stack_1.conf 

Modification at IPSTG level.

o   /usr/var/ss7/platform_a/save_config/SS7_SAVE_CONFIG.DAT.SS7_Stack_1.conf 

• Stop OCMP & USPM
          1st node:
               Stop OCMP Base:
               OCMPClusterConfig
                /> stop cluster
               Stop OCMP BRE: ocmp-bre stop
               Stop USPM: ss7Stop –all 
          2nd node:
               Stop OCMP Base:
               OCMPClusterConfig
               /> stop cluster
              Stop OCMP BRE: ocmp-bre stop
              Stop USPM: ss7Stop -all
• Stop IPSTG
         1st node:
              ss7shutdown a fep dir 
         2nd node:
              ss7shutdown a fep dir
• Check that all processes are stopped (ocStatus, ocftStatus, ps –elf  grep –i ss7)
• Apply changes on all the nodes
• Start OCMP & USPM  
         1st node:
             Start OCMP Base:
             OCMPClusterConfig
               /> start cluster
            Stop OCMP BRE: ocmp-bre start
            Stop USPM: ss7Start 
          2nd node:
             Start OCMP Base:
             OCMPClusterConfig
               /> start cluster
             Stop OCMP BRE: ocmp-bre start
             Stop USPM: ss7Start
• Start IPSTG 
         1st node:
             ss7startup a fep dir 
          2nd node:
             ss7startup a fep dir
• Check that all processes are started (ocStatus, ocftStatus, ps –elf grep –i ss7) and configuration changes were taken into account
• Restore traffic
  

Two remarks:

1. HP recommendation is to use ss7Rmon tool for this change. Easiest and online procedure.
2. This procedure (replacing files) has not been fully tested in our labs so this is under customer responsibility.
