In VSM installation process, it tips database failed to connect.
Check whether the database has been started to confirm whether the parameter is correct, can input the following command in the command line mode to test:
isql -Sservername -Usa -Ppassword
Test whether it can connect the database normally. Also need to check whether the server NIC is normal, because when input the parameters we used the unicast address of the NIC, not the loopback address, so that if the network adapter is not UP, it can't be connected.
The causes of this error basically have the following kinds:
1, database did not start
2, parameter input error
3, server NIC didn’t UP
