RMAN checksyntax function

I was looking at the RMAN DEBUG options and came across the CHECKSYNTAX function which I had not used before.

Firstly a quick recap on the DEBUG option.

This can be called using the following syntax

rman target / catalog rman12g1/xxxx@rmancat debug trace=rmantrace.log cmdfile=backup.rcv

or

rman target / catalog rman12g1/xxxx@rmancat debug trace=rmantrace.log then run RMAN> @backup.rcv (or just type in your run block of commands)

There are a number of options (more...)

How to Create Storage Containers on the Oracle Cloud

When creating a Database Cloud Service, you have an option to select “cloud storage” as a backup destination. In this case, the database backups will be stored in “storage containers”. As I see, lots of Oracle Cloud users have problem with setting up storage containers as backup destination.

It’s possible to create a storage container before you create the database service or you can create it while provisioning the DB service. Whichever method you chose, (more...)

Business Rules: Sums and Averages in Test Conditions by Jaideep

Sometimes in test conditions in rules, there may be a need to test for sums or averages of a collection of values, and these kinds of aggregated values may not be directly available as input facts. For example, in an expense report, you may want to test if the total expenses are above a certain value and then take some action. This is easy if the total value is available directly in the expense report (more...)

Using Read Only Tables

While visiting a customer, we had a conversation about the correct way to stop users from writing to code tables. The customer described his ancient logic: when he wanted to move table to a read only state, he removed the write (insert/update/delete) permissions from all of his users. That was good enough for him for years – since he started using this method way back in Oracle 8. All was well, util this week he (more...)

Expanded ACE Recognition at RMOUG Training Days

The only thing that remains constant is change.   ~Heralitus

chameleon

This often is more apparent in technology than anywhere else.  Even with a group of Oracle evangelists and enthusiasts like the ACE program, which offers the opportunity for peers to recognize those that contribute to the community and help make it a better place.

I’ve [often quietly] assisted many around me to find their path into the ACE (more...)

BPM/SOA Human Task: Java code in jsp source files is not allowed in ojsp.next mode by Antonis Antoniou


clip_image002Today I came across an exception while trying to load one of my task details (v12.2.1).

Error: OracleJSP error: oracle.jsp.parse.JavaCodeException: Line # 14, oracle.jsp.parse.JspParseTagScriptlet@66e50889
Error: Java code in jsp source files is not allowed in ojsp.next mode

What was really strange to me was that I did not do anything different from what I used to do with previous versions.
After some research I found out (more...)

“U” entries in MLOG$

Recently in a discussion with colleague, on what entries do MLOG$ have, the following was agreed to :-

1. “I” for insert
2. “D” for delete
3. “D” + “I” for update.

Along with the above entries, you might notice “U” also. The “U” entry is for update. But then, on what condition do we get “U” and when do we get “D” and “I” entries.

I have used “EMP” table as master table in (more...)

PL/SQL Objects for JSON in Oracle 12cR2

I’ve been playing around with some more of the new JSON features in Oracle Database 12c Release 2 (12.2).

The first thing I tried was the new PL/SQL support for the JSON functions and conditions that were introduced for SQL in 12.1. That was all pretty obvious.

Next I moved on to the new PL/SQL objects for JSON. These are essentially a replacement for APEX_JSON as far as generation and parsing of JSON data (more...)

Best practice for calling web services from Oracle Process Cloud Service by Lykle Thijssen

clip_image002

More often than not, you will want your processes to interact with other services or processes inside or outside your enterprise. Since integration options are rather typical in Oracle Process Cloud Service, this article will help you to apply best practices for creating and managing your connections in a sustainable fashion.

Process Cloud integration points

Let’s say you have modelled a process in Oracle Process Cloud Service (PCS) for a private home loan application. Chances (more...)

A Guide to the Oracle TRUNCATE TABLE Statement

The Oracle TRUNCATE TABLE statement is a useful statement for removing data in Oracle SQL. I’ll explain what the statement does and show you some examples in this article. What Does the Oracle TRUNCATE TABLE Statement Do? The Oracle TRUNCATE statement, or TRUNCATE TABLE statement, removes all data from a table. It’s similar to the […]

Fixing Dataguard Wrong File Location Problem

When we add a new datafile to the primary environment of a dataguard setup, we need to add the datafile to the standby environment as well if we want the manged recover to continue working. We can do that manually if we want – but fortunately for us Oracle comes with a built in feature for automatically creating the file in the standby as well. All we need to do to set it up is (more...)

Enabling Flashback – Be Cautions

Enabling flashback on 11.2.0.4 database can take minutes and cause multiple database wait events degrading database performance.

On a quite busy system, during the low peak hours, I tried to enable flashback on 11.2.0.4.6 version database and multiple sessions waited on

Custom xpath functions in service bus by Milco Numan

clip_image002

How can you create  custom XPath functions in Oracle Service Bus 12c? And how can you use these in both  XSLT and XQuery? Let’s find it out. I like to show you how they’re different in behaviour.

The context of my post comes from one of my projects, where we were migrating quite some (stateless) services from the SOA (BPEL) platform to Service Bus. Since our clients were already ‘virtualized’ to our clients (i.e. (more...)

APEX 5.1 Installations and Upgrades

APEX 5.1 was released for download a few days ago. I tried doing an upgrade against an installation on a VM at home and it worked fine, which was hardly surprising. 🙂

Officially I’m on holiday, but I figured I would upgrade all our Dev/Test installations while everything is quiet. Major version upgrades, changes in either of the first two numbers, require a full installation. There was no major difference between this and what I (more...)

In the last weeks I had the privilege to test some of our upcoming PaaS middleware solutions by myself. One of the results a full integration scenario developed by drag and drop - you can see above. It is amazing how fast, easy, nice and rich integrations, can be built by a citizen developer like myself. Hope to see you all at the PaaS Partner Community Forum 2017! #jkwc

interconnect fragmentation kills the cluster

On a particular Oracle 2 node cluster (12.1) we faced random instances failing. Servicerequests at Oracle were open with limited result, as it was quite random and we could not link it to any trigger.
As it looked somehow like a communication problem between the 2 nodes, network team has checked the switches involved - without any outcome.
Even crashing instances were a problem already, it get worse one day when one node rebooted (more...)

Oracle MEDIAN Function with Examples

In this article, I’ll explain what the Oracle MEDIAN function is, and show you some examples. Purpose of the Oracle MEDIAN Function The MEDIAN function returns the median of the set of provided values. The MEDIAN is the middle value in a set of values. So, for example, you had these five values: 10, 15, […]

Inserting data in SQL*Plus correctly

When inserting data into the database, it is occasionally forgotten (especially by English-speakers) that we need to take steps to ensure we are inserting data correctly and without unexpected character translation.

For example, in SQL*Plus we need to ensure we set the NLS_LANG environment variable to the correct setting for our database before we initiate SQL*Plus.

Here’s a quick example showing what can go wrong:

[oracle@ORA122 ~]$ echo $NLS_LANG

[oracle@ORA122 ~]$ sqlplus neil/neil
