Using a terminal emulator on Mac

Dumb title for a blog post? No, not really I guess…

ZOC Terminal emulatorI have been using a terminal emulator, basically ever since I got away from the VT100 terminal:

  • ICE.TCP Pro
  • KEAVT
  • Reflection ‘X’

And a few other obscure applications that I cannot even recall anymore.
Currently, and over the last 6 to 8 years, I have been using ZOC.

The background of this story is: In the beginning these were the first DOS PC’s (more...)

Register redo-log manually with Divisit Replicate

For those of you who haven’t been working with on-line data replication; in short, it is a way to copy data from a source database to a target database and do this on-line (both databases are active) and do it near-real-time.
This means that when you enter data in you source database, you can immediately query it from your target database. This makes on-line data replication ideal for numerous tasks, like moving and / or (more...)

Updating SQL Developer to use newer Java version

I was being teased by SQL Developer.

Everytime I started it came nagging about that it was being forced to live in an old Java version called jdk1.7.0_45 and that is was not feeling happy about it.
So, I should remedy this, I thought to myself.

First visit was, inspired by some search-work on the WWW, a file called product.conf. Which offered two possiblities:

java

SetJavaHome to some logical location
or

Setting up SQL Instant Client on MAC

In doing more work directly from my Macbook Air, I ran into a situation where native connectivity to an Oracle environment was needed.Connectivity over Oracle Instant Client
From experience I have always been a big fan of the Full Oracle client, just because it comes with a lot of tools and utilities for troubleshooting, which makes the actual experience a bit more pleasant.
Looking & asking around, though, I learned fairly quickly that this client is just not (more...)

Oracle on OpenVMS – revival

Can it be true?

Will there be Oracle on OpenVMS again? Meaning the “regular” (sorry) Oracle (12c) RDBMS on a revived VMS?

As many who have ever lived on OpenVMS have always known:

OpenVMS will never die!

OpenVMS can never die, becOpenVMSause it is still running way to many hidden, hyper-mission-critical environments.
The fact that these environments are hidden, combined with the fact nobody ever spent any marketing budget on OpenVMS at all, created (more...)

Big Data: Hadoop and Oracle technologies explained

MarkRittmanUnder the title “Hadoop and Oracle technologies on BI projects” Mark Rittman flew to The Netherlands on the 14th of July to visit the Oracle Usergroup Holland.

As I had obviously heard a lot about Hadoop, I never really did anything further with it and left it to a synaptic link to Gwen Shapira. This lack of action created a kind of threshold in the understanding of the technology. When I heard about this (more...)

Patching Time

Just a quick note to point out that the October PSU was just released. The database has a few more vulnerabilities than usual (31), but they are mostly related to Java and the high CVSS score of 9 only applies to people running Oracle on windows. (On other operating systems, the highest score is 6.5.)

I did happen to glance at the announcement on the security blog, and I thought this short (more...)

Grid/CRS AddNode or runInstaller fails with NullPointerException

Posting this here mostly to archive it, so I can find it later if I ever see this problem again.

Today I was repeatedly getting this error while trying to add a node to a cluster:

OSP #3a: Build a Standard Cluster Platform

This is the fifth article in a series called Operationally Scalable Practices. The first article gives an introduction and the second article contains a general overview. In short, this series suggests a comprehensive and cogent blueprint to best position organizations and DBAs for growth.

We’ve looked in some depth at the process of defining a standard platform with an eye toward Oracle database use cases. Before moving on, it would be worthwhile to briefly touch (more...)

Chicago Oracle User Community Restart

Chicago is the third largest city in the United States. There are probably more professional Oracle users here than most other areas in the country – and yet for many years now there hasn’t been a cohesive user group.

But right now there’s an opportunity for change. If the professional community of Chicago Oracle users steps up to the plate.

Chicago Oracle User Group

First, the Chicago Oracle User Group has just elected a new (more...)

Command Line Attachment to Oracle Support Service Request

For those who haven’t looked at this in awhile: these days, it’s dirt simple to attach a file to your SR directly from the server command line.

curl –T /path/to/attachment.tgz 
     –u "your.oracle.support.login@domain.com" 
     "https://transport.oracle.com/upload/issue/0-0000000000/"

Or to use a proxy server,

curl –T /path/to/attachment.tgz
     –u "your.oracle.support.login@domain.com"
     "https://transport.oracle.com/upload/issue/0-0000000000/"
     -px proxyserver:port
     -U proxyuser

OEM CLI Commands for Bulk Property Changes

This will be a brief post, mostly so I can save this command somewhere besides the bash_history file on my OEM server. It may prove useful to a few others too… it has been absolutely essential for me on several occasions! (I was just using it again recently which reminded me to stick it in this blog post.) This is how you can make bulk property changes to a large group of targets in (more...)

November/December Highlights

In the Oracle technical universe, it seems that the end of the calendar year is always eventful. First there’s OpenWorld: obviously significant for official announcements and insight into Oracle’s strategy. It’s also the week when many top engineers around the world meet up in San Francisco to catch up over (more...)

Readable Code for Modify_Snapshot_Settings

It annoyed me slightly that when I googled modify_snapshot_settings just now and all of the examples used huge numbers for the retention with (at best) a brief comment saying what the number meant. Here is a better example with slightly more readable code. Hope a few people down the road (more...)

Largest Tables Including Indexes and LOBs

Just a quick code snippit. I do a lot of data pumps to move schemas between different databases; for example taking a copy of a schema to an internal database to try to reproduce a problem. Some of these schemas have some very large tables. The large tables aren’t always (more...)
