Question
DPC configuration change procedure
Answer
- 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.xmlo /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.confModification at IPSTG level.o /usr/var/ss7/platform_a/save_config/SS7_SAVE_CONFIG.DAT.SS7_Stack_1.conf

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.
