First things first. If you are not familiar with the term “gets my goat” then you can find a definition here . But put simply, it means things that you find frustrating or bothersome.
What is getting my goat today is the time it takes to get the DDL for a database object using the DBMS_METADATA package. It always seem slow to me. Now I must admit, this is very much me exhibiting “never happy” syndrome, because before DBMS_METADATA came along, generating DDL from the database was an absolute pain in the proverbial. Your choices were either:
If you follow me, Jeff or Kris on Twitter, you will already know ORDS, SQLcl, SQL Developer and SQL Developer Data Modeler version 19.4 have all been released. They became available for download late Friday US time, and I got a DM about it yesterday morning, so fresh from spending 2 days running Data Guard builds, I moved on to running builds of some of this stuff.
It was a long day, but this is what I did.

You like SQL Developer because it is easy to install (just unzip a jar) and has a lot of features? Me too. It can be even easier if it is provided as a web application: no installation, and no java to take all my laptop RAM…
When I say no installation, you will see that you have some little things to setup here in DBaaS. That will probably be done for you in the managed services (PDBaaS) such as ‘Express’ and ‘Autonomous’ ones.
Here is a quick SQL Developer report which display a chart about the Dbvisit replicate lag over the last hours
The idea is to have the following chart showing the lag in MINE and APPLY processes. Here is an example where I stopped the replication to show some lag.
The query is on the DBVREP.DBRSCOMMON_LAG_STATS on the APPLY side, which display the wallclock time with timestamp from the MINE and from the APPLY.
Here is the SQL Developer report .xml:
The latest version of SQL Developer, the 17.2 one released after Q2 of 2017, has a new item in the DBA view showing the Data Guard configuration. This is the occasion to show how you can cascade the log shipping in Oracle 12c
A quick note about this new versioning: this is the release for 2017 Q2 and the version number has more digits to mention the exact build time. Here this version is labeled 17.2.0.188.1159 and we can see when it has been built:
SQL> select to_date('17.x.0.188.1159','rr."x.0".ddd.hh24mi') build_time from dual;

Where do oracle trace files go? I don’t know why this piece of info will not stick in my head, I seem to have to look it up 3 or 4 times a year.
If only I had an easy way to find out. There is a very easy way to find out – and that piece of info won’t stay in my head either. So this really is a blog post just for stupid, forgetful me.
V$DIAG_INFO has been available since oracle V11. All the trace files go into the Automatic Diagnostic Repository (ADR) by default.
Oracle have given birth to SQL Developer 4.0 today, as announced by Jeff Smith.
SQL Developer 4 EA2 includes a performance node in the DBA tree.
You can use this to view ADDM, AWR and ASH reports directly from SQL Developer. I know I can get these from Cloud Control, but previously I tended to pull these out from the command line on the server. This is a much better approach IMHO.
I wrote a blog post some time ago about using SQL Developer 3.x to connect to SQL Server. I tried the same thing today from SQL Developer 4 EA2 and it works just fine.
You have to download the 3rd party JDBC driver and point SQL Developer to it. You can read how to do it here.
Cheers
Tim…
Update: My colleague just told me this.
“If you at any point decide to use Windows authentication to connect (like I just did), you might hit this error:
Status : Failure -I/O Error: SSO Failed: Native SSPI library not loaded. Check the java.library.path system property.

Many Oracle Database users like tools with GUI interfaces because they add features and functionality that are not easily available from the command line interfaces like SQL*Plus. One of the more popular tools from my experiences is Oracle SQL Developer in part because it’s a free tool from Oracle. Given SQL Developer’s current design (as of version 3.1.07.42), some issues frequently show up when using it with Oracle Databases with Parallel Execution. SQL Developer also contains a bug that exacerbates this issue as well.
