areas to consider
Overall cost per Oracle seat - RH wins
System support - HP wins
Support cost - HP more RH less (but less robust)
System training - HP == RH in cost, dunno about quaility
Availability of sysadmin staff: RH wins.
Hardware support - HP wins RH is limited
High availability - HP wins, unless RH is clustered to allow failovers, then RH comes out ahead but loses ground on cost.

IMO -
Long term, overall software/hardware/operations costs tend even out because A costs more in labor or down time or prting software, but B costs more upfront for hardware and software. And so on. I do not see RH as a huge win.

You also really have factor in the cost of porting software.

Base C code from HPUX does not compile well under RH gcc -Wall, for example.

Shell scripts may have to be rewritten, especially if you use hpux /bin/sh. We just did that. Even though /bin/sh is supposedly POSIX there are small gotchas going to bash, for example.

C system code, if you have any, will have to be looked at. Very minor semantic differences can create interesting results. If you use acl's it is also interesting. You can't really port file acl metadata directly, AFAIK....

How Many CPUs? (Itanium)

I've got a dual CPU Itanium server that we use for hosting our Oracle database. It's been up and running fine for quite some time. So well, in fact, that I haven't even looked at 'top' in a while. Recently I needed to look at 'top' and I only see one CPU listed now. CPU0. Is there any other... (5 Replies)

DBIx::Class::EncodedColumn::Crypt::Eksblowfish::Bcrypt(3User Contributed Perl DocumentaDBIx::Class::EncodedColumn::Crypt::Eksblowfish::Bcrypt(3pm)

NAME
DBIx::Class::EncodedColumn::Crypt::Eksblowfish::Bcrypt - Eksblowfish bcrypt backend SYNOPSYS
#Eksblowfish bcrypt / cost of 8/ no key_nul / generate check method __PACKAGE__->add_columns( 'password' => { data_type => 'CHAR', size => 59, encode_column => 1, encode_class => 'Crypt::Eksblowfish::Bcrypt', encode_args => { key_nul => 0, cost => 8 }, encode_check_method => 'check_password', } DESCRIPTION
ACCEPTED ARGUMENTS
key_nul => [01] Defaults to true. From the Crypt::Eksblowfish::Bcrypt docs Boolean: whether to append a NUL to the password before using it as a key. The algorithm as originally devised does not do this, but it was later modified to do it. The version that does append NUL is to be preferred; not doing so is supported only for backward compatibility. cost => dd? A single or double digit non-negative integer representing the cost of the hash function. Defaults to 8. METHODS
make_encode_sub $column_name, \%encode_args Returns a coderef that accepts a plaintext value and returns an encoded value make_check_sub $column_name, \%encode_args Returns a coderef that when given the row object and a plaintext value will return a boolean if the plaintext matches the encoded value. This is typically used for password authentication. SEE ALSO
