  1. Shutdown Powercenter services.

  1. Generate a new keystore with signature algorithm SHA1withRSA
    • <INFA_HOME>/java/bin/keytool -genkey -dname “CN=infa-server, OU=Informatica, O=Informatica, L=RedwoodCity, ST=California, C=US” -alias infa_dflt_new -keypass <Informatica Admin Password> -keystore mykeystore -storepass keypass <Informatica Admin Password> -keyalg “RSA” -validity 365

  2. Copy the keystore, for example, “mykeystore” to any directory
