HammerOra Quick Start...

Its time to test some IO.

I have used OraBM/OraStress in the past to throw a load at an Oracle server.

This time I wanted to see what else was out there. I had seen mention of HammerOra on forums and listserves so I figured I'de give it a shot. Here's what it took to get it running on a Windows server.

1) Download and Install HammerOra

Their home page is here: http://hammerora.sourceforge.net/

I can't login! The server is down!

Yup. I'm tired of hearing this from users. Since I changed jobs from a software development house to a more focused DBA role I hear this a lot. As much as I'de like to just log into their app server and comb through logs to find the problem like the old days... I have to debug what I can from the server side and get the app server folks looking from their end. Here is a quickie script that should work on most Unices.

Manage other user's jobs with DBMS_IJOB...

I had a user that called me about jobs not running on a 9i database. I logged in and found a complete mess. Broken jobs, some DBMS_JOB calls would hang, jobs existed for users that no longer existed (I didn't even know that was possible!). Because things were such a mess I just wanted to remove all the jobs and start from scratch. But I needed to drop jobs for a user that no longer existed. Using DBMS_JOB even SYS does not have complete control of jobs. How can I remove a job for a user that no longer exists? Enter DBMS_IJOB.

More stupid RMAN tricks: ORA-01843 From RMAN

So I've got a backup script that runs a BACKUP DATABASE followed by a BACKUP ARCHIVELOG command. The BACKUP ARCHIVELOG FROM TIME command runs to collect all the archived logs created since the beginning of the Level 0.

Beware of old clients...

No, not old customers, old Oracle client software!

I was recently asked to write a ON LOGON trigger for an database (don't ask, it is a very old system). Wrote the trigger, tested it, works no problem. It is never that simple.


SftpDrive - map drives to your windows workstation via SSH...

Just heard about this software today from a satisfied user. SftpDrive is a software package for Windows that allows you to map a SSH server as a Windows network drive. This enables you to use a Windows PC for development but to modify files directly on a Linux/Unix server.

It costs to register the software but they have a 6 week free trial. Considering the amount of time I could save during development I think I will be adding this tool to my dev workstation: https://www.eldos.com/sftp-net-drive/

Getting my feet wet in Apex...

So the new place I work has some small applications built in Apex. I'm getting ready to build some monitoring tools and wanted to integrate their functionality into the apps that are already available.


DBI and mod_perl for Oracle 10g HTTP Server

Looks like Oracle has finally come around and made it easier to incorporate the DBI module into the Oracle HTTP Server. The 10gR2 HTTP Server Administrators guide also has a laundry list of other modules that are enabled by default or easily turned on. Here is the mod_perl section of the 10gR2 HTTP Server Admininistrators Guide: click here

XML/SWF Charts by Maani.US

I found a new graphing/charting tool that I am really digging. I'm letting Munin simmer for a while because it seems like its mostly geared towards being a network admin/reporting tool. I want graphs and I want to make them available on web pages. I'm not asking for much right?

If a browser based Flash solution is a possibility for you, check out XML/SWF Charts by Maani.US.

Need a word list?
