Using staticports.ini for Oracle HTTP Server during OAM/EBS Integration

Using staticports.ini for Oracle HTTP Server during OAM/EBS Integration

Instead of 7777 of HTTP Server port, we had a requirement for 7778... 

HTTP WebTier Version 11.1.1.6

Create a file staticports.ini before starting the installation, and choose manual port configuration:

[OPMN]
OPMN Local Port = 6706
OPMN Remote Port = 6707

[OHS]
OHS Port = 7778
OHS Proxy Port = 9998
OHS SSL Port = 4444

[WEBCACHE]
Web Cache Listen Port = 7790
Web Cache Admin Port = 7791
Web Cache Statistics Port = 7792
Web Cache Invalidation Port = 7793
Web Cache SSL Port = 7794
