Installing PHP 5.4.0RC8 and Apache 2.4 on Ubuntu 11.10

php54Apache241About once every other week I try and spend some time at work thinking ahead. With PHP 5.4 on the horizon I began to wonder how our current Zend Framework application would fare if the SysAdmins decided to jump straight from PHP 5.2 to PHP 5.4. Would the site work at all? One way to find out. Lets install PHP 5.4RC8 and Apache 2.4.

I started by creating a fresh Ubuntu 11.10 VM. In complete disclosure, I removed some of the unneeded packages like LibreOffice first. I then cloned it so I would always have a base to work off of in the future.

PHP Oracle [notice] child pid NNNN exit signal Bus error (10)

After some frustration I learned from a forum post that the default password time limit for Oracle 11g is 120 days. Once you get close to that you will go into a grace period, where PHP’s oci connection dies on you with no explanation. You will notice a message like this in you apache log:

  • [notice] child pid NNNN exit signal Bus error (10) in the apache log.

Step 1: Change your password, or rather lets just keep it as it is…

  • ALTER USER myname IDENTIFIED BY mypassword

Step 2: Make us not have to do this again:

  • ALTER PROFILE DEFAULT LIMIT PASSWORD_LIFE_TIME UNLIMITED;

Hope this helps someone.

Eliminating Mysterious Oracle Indexes

Oracle by default will create cryptic names for indexes unless you specify your own. To get a list of all the indexes currently in use for your schema you can execute:
> select * from user_indexes;
Anything that starts with SYS_ and ends with a $ is an autogenerated index name. It is good to have a common format for your indexes so that any errors are meaningful. address_id_pk is much more readable than SYS_IL0000088969C00006$$. Over here we use the [table]_[column]_[type] format so we can know at a glance where to hunt for the problem.

While doing this I noticed that LOB and CLOB field types automatically generate a SYS_blahblahblah$$ index, polluting your clean design. If that rubs you the wrong way, you can specify the index name for them as well, but the code is a bit messier.
