Issue:
Informatica Admin Console url which is a Secured site (https://hostname:8443), suddenly stopped working with the message in Browser “CYPHER MISMATCH (DSA keys)”
Resolution:
- Shutdown Powercenter services.
- Delete the folders and files under following folders:
- <INFA_HOME>\tomcat\temp
- <INFA_HOME>\tomcat\work
- Delete only the folders and DO NOT DELETE the .war files in <INFA_HOME>\tomcat\webapps
- 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
- <INFA_HOME>/java/bin/keytool -selfcert -alias infa_dflt_new -sigalg “SHA1withRSA” -keypass changeit -storepass <Informatica Admin Password> -validity 365 -dname “CN=infa-server, OU=Informatica, O=Informatica, L=RedwoodCity, ST=California, C=US” -keystore mykeystore
- <INFA_HOME>/java/bin/keytool -list -v -keystore mykeystore –storepass <Informatica Admin Password>
- Copy the keystore, for example, “mykeystore” to any directory
- Change to directory <INFA_HOME>/isp/bin
