Using IMA to get a list of inbound/outbound connections in GCC

2011-01-12T11:59:00Z

A question recently came up on the Ingres forums regarding the ability to query IMA to get a count and list of out bound sessions in the GCC servers. The former can be done using an existing IMA table, ima_gcc_info, like so:

execute procedure ima_set_vnode_domain;
select outbound_current from ima_gcc_info;

The latter is a bit more involved as there is no IMA table registered that exposes the relevant information. Browsing ima_mib_objects using:

select distinct(instance) from ima_mib_objects where instance like '%gcc%'

gives a nice list of GCC related entries we can query:

* select distinct(instance) from ima_mib_objects where instance like '%gcc%'\g
Executing . . .

The lcl_addr and rmt_addr entries look useful so let’s create a table with the node and port sub-fields:

drop table ima_gcc_sessions;
register table ima_gcc_sessions (
        net_server                  varchar(64) not null not default
    is 'SERVER',
  local_node         varchar(20) not null not default
    is 'exp.gcf.gcc.conn.lcl_addr.node',
  local_port         varchar(20) not null not default
    is 'exp.gcf.gcc.conn.lcl_addr.port',
  remote_node         varchar(20) not null not default
    is 'exp.gcf.gcc.conn.rmt_addr.node',
  remote_port         varchar(20) not null not default
    is 'exp.gcf.gcc.conn.rmt_addr.port',
  inbound         varchar(20) not null not default
    is 'exp.gcf.gcc.conn.inbound'
) as import from 'tables'
with dbms = IMA,
structure = sortkeyed,
key = (net_server);

So to get a list of outbound server connections we can now use the following SQL:

select * from ima_gcc_sessions where inbound='N'

Giving:

* select * from ima_gcc_sessions where inbound='N'\g
Executing . . .

Ingres Ruby demo application

2010-12-01T12:56:27Z

For those of you interested in learning how to use the Ingres Ruby driver I’ve uploaded a demonstration application to http://esd.ingres.com. The demo, entitled “Frequent Flyer” demo, is a stand alone application that uses the TK GUI controls via RubyTK bindings to provide the visual interface with the Ingres Ruby driver used to connect to the demodb database. For more information about the demo app and to download the code go to http://community.ingres.com/wiki/Ruby/Learn/Flight_Planner_Demo_Application.

Ingres Ruby driver updated – version 1.4.1

2010-12-01T12:56:54Z

Last week I pushed out a minor update for the Ingres Ruby driver to address issues seen in a soon to be published demo (more about that in another post). The changes in this new release are as follows:

Fix #656 – getProcedureName() returns a non-NULL terminated procedure name
Fix #653 – Update s.date dynamically for each release
Fix #651 – Add support for building a Ruby Gem
Fix #555 – SEGV when fetcing LOB data
Fix #565 – Compilation errors with Redhat ES 5.4 (x86-64)

This new release can be obtained from ingres.com or via one of the following links:

Alternatively you can checkout this release from our external source code repository:

svn checkout http://code.ingres.com/ingres/drivers/ruby/tags/ingres-ruby-1.4.1

See http://community.ingres.com/wiki/Connectivity_Drivers_Source_Code for more information on working with our external source repository.

Issues specific to the Ingres ActiveRecord adapter and Ruby driver can be posted on the Ingres forum http://community.ingres.com/forum/ruby-driver-ruby-rails-adapter/. Users with an active support contract can raise an issue through their local support centre or Service Desk.

Improving the Improved – docs.ingres.com

2010-08-06T14:50:21Z

As noted elsewhere this week saw the relaunch of the Ingres documentation site http://docs.ingres.com. At last we have the ability to deep link into the documentation without having to do acrobatics to extract links in the docs, for example

http://docs.ingres.com/Ingres/9.3/Database%20Administrator%20Guide/largedataloadswsetnologgingstatement.htm

has become

http://docs.ingres.com/ingres/9.3/database-administrator-guide/1757-large-data-loads-with-the-set-nologging-statement

To get the URL for the first required some navigation of the documentation index, via the tree or via the search engine. Since Google is used by many people as their home page, even to search for facebook.com it makes more sense that the documentation is more accessible from Google, Bing et. al.

One of the downsides with the new docs.ingres.com site is the use of screen real-estate. The main ingres.com properties have their content squeezed in to 980px which is ok in the 1990 world of “This website supports 1024×786″ resolutions. However in this day and age I would make the supposition that 1280×1024 would be more common, something that’s borne out by Valve Software’s monthly hardware survey. With the increasing trend towards wide-screen displays in laptops as well as desktop displays a 1440×900 resolution will become more common.

With this in mind I’ve put together a couple of hacks that when used with Google Chrome or the Firefox Greasemonkey addon – increases the amount of space used for the content to 60% of the width of the browser window. To install, click on the relevant link for your browser – note that the Greasemonkey script can be used with Google Chrome (from 4.0 onwards).

Google Chrome – http://planetingres.org/~grant/bigdocs/bigdocs.crx
Firefox with Greasemonkey – http://planetingres.org/~grant/bigdocs/bigdocs.ingres.com.user.js

Once installed go to any docs.ingres.com page and after the page finishes loading the content area will be super-sized. If there’s any interest I’ll look into to how the page can be rendered full size without having to expand on screen.

Changes to the Ingres RPM installer

2010-08-04T17:54:45Z

Over the last couple of days I’ve done couple of Ingres installations using the latest, bleeding edge, RPMs and have come across a change in behaviour that might catch you out, as indeed it did me. What follows is a more or less verbatim copy of the output from an install of the latest SVN head revision I performed earlier today:

[grant@usrc-git T1]$ sudo rpm -ihv ingres-32bit-T1-10.1.0-00.x86_64.rpm ingres-dbms-T1-10.1.0-00.x86_64.rpm ingres-odbc-T1-10.1.0-00.x86_64.rpm

Prior to Ingres 10.1, the RPM install scripts would perform the post-laydown configuration. As of 10.1 this is no longer the case as you can see from the output above. The 10.1 RPMs only lay down the files and do minimal configuration, which sets up the symbol table as per the output from ingprenv. Ingres now gets configured when started as a service for the first time:

[grant@usrc-git T1]$ sudo service ingresT1 start
Ingres, instance T1 has not been setup

PECL ingres-2.2.2 released

2010-06-29T09:16:31Z

Yesterday I pushed out an update to the PHP driver for Ingres into the PHP Extension Community Library (PECL). Whilst it’s been labelled as a minor update there have been 15 fixes/additions to the driver:

- Update the unit tests to be more independent
- Add support for the Ingres BOOLEAN type
- Add ingres_fetch_assoc()
- Allow for a 0 offset in all ingres field functions
- Update build scripts for OpenVMS CSWS PHP 2.0
- Fix bug 17556 – Handle errors for non-result returning statements
- Fix bug 16960 – SEGV when fetching the results from a row producing procedure
- Fix bug 16990 – SEGV when executing a database procedure
- Fix bug 17510 – Fix php_ii_set_connect_options so they work as documented
- Fix bug 17302 – _close_statement is unable to free active statements
- Fix bug 17207 – Under certain conditions the driver can SEGV when doing cleaning up
- Fix bug 17198 – Unable to close non-result statements
- Fix bug 17092 – SIGBUS when fetching data on 64-bit Solaris
- IIapi_getDescriptor() should only be called for SELECT statements
- Fix bug 16752 – Send all string values as IIAPI_VCH_TYPE

You can download the source code from http://pecl.php.net/get/ingres or install directly from the command line using the command:

sudo pecl install ingres-2.2.2

Pre-built Windows binaries are available from ESD for PHP 5.1.6, 5.2.13 and 5.3.2. An OpenVMS binary for CSWS PHP 2.0 will be updated today. You can raise questions/problems via the Ingres Community Forums, the project home page or via Service Desk.

Ingres 10.0 – “sql -history_recall” now enabled by default

2010-04-30T11:46:16Z

History what?

For some time the Ingres terminal monitor has had the, slightly cryptic (to me at least), flag “-history_recall”. This flag allows you to use the cursor keys within a terminal monitor session to scroll through previous queries and edit them in-line. Users of Ingres on Windows have been able to do this by default, without any special flags, by virtue of Microsoft Windows Console API. As of change 2911 this feature is now active by default on UNIX/Linux and should be part of Ingres 10.0 when it gets released.

Ingres 10.0 – Escaping from the Ingres terminal monitor

2010-06-29T10:47:09Z

For new users to Ingres quitting from the Ingres terminal monitor, tm or sql, just got easier. With change 2901 the terminal monitor has gone from this:

$ sql iidbdb
INGRES TERMINAL MONITOR Copyright 2010 Ingres Corporation
Ingres Linux Version II 10.0.0 (int.lnx/2863)NPTL login
Thu Apr 29 08:46:38 2010
continue
*

to:

$ sql iidbdb
INGRES TERMINAL MONITOR Copyright 2010 Ingres Corporation
Ingres Linux Version II 10.0.0 (int.lnx/2903)NPTL login
Thu Apr 29 09:16:40 2010
Enter \g to execute commands, "help help\g" for help, \q to quit
continue
*

No more ninja skills needed for executing a query or to escape from the terminal monitor.
