Assumptions
a.
Oracle and the pol2p database is ready on
TDC server.
b.
File directory exists exactly as it does currently on the
mdctxubsdm01 AIX server.
c.
Users are configured with permission's as they are on the BSDM01
server.
d.
All files have been mirrored to exist on the TDC server.
e.
TDC server name will NOT be different than current server and will
resume the identity of the current server.
f.
Host names are used by internal jobs on both the mainframe and
GISB servers that forward jobs to MDCTXUBSDM01.
g.
Parser should come up based on the cloning of the system.
III.
Overview of the Testing
of the Recovery Plan
a.
Database has been cloned from the last hot-backup of production.
b.
Database has been brought up on the DR server and verified
operational.
c.
Parser will not be tested due to identified conflicts with having
the production Parser operational.
d.
The only difference between the DR site and the current production
site will be the IP addresses of the servers.
e.
Operating system was built by cloning everything in the root
volume group.
f.
User accounts and passwords were cloned.
g.
CRON schedules, security, system parameters were also cloned.
IV.
Recovery Plans
a.
Rename / re-point DNS name from DDCAPPLS01 to MDCTXUBSDM01. Done
by the SE AIX Team
b.
Restore backup DB files from TSM. Done by the DBA Team and Storage
Team. This will recover the data to a 7 day recovery point. Additional steps
(documented below) are required to pull the RPO to within 24 hours.
c.
Start DB abd issue media recovery from
logs. Done by the DBA Team.
d.
Begin application checkout. Done by the Application Team.
e.
Manual load files from ERCOT and EPN. Done by the DBA and
application Teams. This applies all transactions to current day and meets the
24 hour RPO objective.
f.
Uncomment CRON jobs. This is done by the DBA and SE AIX teams.
g.
Update all data feed configuration files as well as code(where necessary) to reflect the new TDC server. Done by
the Application Team. This will be used by all feeds that ftp us information
hourly/daily. The feeds are listed in order of importance. All these data feeds
currently use the etcamftp or jparser
user id.

PCDTHADD PCDTHINS PCDTHKLC
PCDTHKLI PCDTHKLX PCDTHMTR
PCDTHOPC PCDTHOPI PCDTHOPR
PCDTHOPX PCDTHPRE PCDTHSOR
