Rami — Sat, 17 Mar 2007 21:30:07 +0000

Change the new user’s default tablespace to the new tablespace:
alter user scott default tablespace newspace;
Revoke the unlimited tablespace and change the new user’s quota to have space only on the new tablespace:

Do the import.

Generating A Self Signed Certificate For IIS

Rami — Fri, 09 Mar 2007 16:40:19 +0000

Generate the CA key:
openssl genrsa -des3 -out ca.key 1024
Generate the CA certificate:
openssl req -new -key ca.key -x509 -days 1095 -out ca.crt
Generate the IIS certificate by using the CSR generated from IIS:
openssl x509 -req -days 1095 -in certreq.txt -CA ca.crt -CAkey ca.key -CAcreateserial -out cer.crt
Export the CA certificate to DER encoded binary format if needed to be installed on a WM5 device:
openssl x509 -in ca.crt -outform DER -out ca.cer

To install Oracle 10g on Solaris 10 do the following:

Add the SUNWi15cs and the SUNWi1cs packages.
Create the needed groups:

groupadd -g 100 oinstall groupadd -g 101 dba

Create the oracle user:

useradd -u 100 -g 100 -G 101 -d /data/oracle -m -s /bin/tcsh oracle

Create the oracle project:

projadd oracle

Edit /etc/user_attr and add the following:

oracle::::project=oracle

Set the max.shm.memory and max.sem.ids for the project:

URLEncode And URLDecode For Perl

Rami — Sat, 19 Nov 2005 14:50:36 +0000

PHP has builtin functions for urlencode and urldecode functions but for perl I’ve found the following from HERE that does the same thing:

sub URLDecode { my $theURL = $_[0]; $theURL =~ tr/+/ /; $theURL =~ s/%([a-fA-F0-9]{2,2})/chr(hex($1))/eg; $theURL =~ s///g; return $theURL; }
sub URLEncode { my $theURL = $_[0]; $theURL =~ s/([\W])/”%” . uc(sprintf(”%2.2x”,ord($1)))/eg; return $theURL; }
