What is the Embeddability Toolkit ?

Informix Embeddability Toolkit empowers
the customer with the tools and the
information they need for easy automation
of reduced footprint Informix deployments.

It includes:
• Informix Deployment Assistant (DA)
• Informix Deployment Utility (DU)
• DU's Configuration File
• Additional Scripts for Embedding Informix
• A Tutorial on an end to end Deployment Solution


Why do we need deployment utility ?

Quickly and easily deploy pre-configured Informix
to multiple locations.

Upgrade multiple instances to a different fixpack

Embed an Informix application on multiple
computers and want to reduce application
installation


Why do we need deployment utility ?

Create a snapshot with initialized dbspaces -> can
deploy product+instance with dbspaces

Tune only first instance as a template and deploy it
on multiple computers
• Perfect to install on mutiple developer systems


Limitations

Difficulty to create a snapshot with dbspaces of
24x7 production instance

– Copy of chunks will block the instance

– Raw devices not supported


Deployment Assistant (DA)


Package it.


Enables users to take snapshots of Informix
instances and / or data spaces for deployment on
other target computers.

Allows for reduction of the packaged instance to
the user's minimum desired configuration

Provides both GUI and Command-Line Interfaces
developed using Java/Eclipse SWT

Snapshots produced by DA are ready for use by
the Deployment Utility (DU) for deployment on the
target computers

DA: Prerequisites
Java Runtime Edition version 1.6 (6.0) or later.
The Informix 11.70 server's Krakatoa JRE can be
used to satisfy this requirement. It is located at
<INFORMIXDIR>/extend/krakatoa/jre/bin

In order to package an instance's data, users must
have connect privileges to the sysadmin database


DA: Limitations/Considerations
Unsupported Platforms
• HP
• zLinux

No current support for data on RAW devices
Currently works with instances on the local system
only
Must be able to make a trusted connection to local
Instance.
Does not resolve dependencies between features
when deselecting feature to exclude from
deployment.


DA: Limitations/Considerations
start the Deployment Assistant, run the
following command in <INFORMIXDIR>/bin:
• ifxdeployassist
• ifxdeployassist.app/Contents/MacOS/ifxdeployassist on Mac OS

Instance must be online

DA will block instance like external backup


DA: GUI Instance Detection
Once automatically
detected, information
regarding the instance is
displayed

• Yes – DA will create a snapshot
based on the displayed
instance

• No – prompts for connection
information for the instance to
create a snapshot of


DA: GUI Connection Parameters
Supply connection
information for the
instance to create a
snapshot of.

Displayed whenever:
• An instance is not
automatically detected
• No was selected when an
instance was automatically
detected


DA: GUI Snapshot Location
Specify the location in
which the snapshot of the
Informix instance and/or
data will be saved.

The archive formats
available are:

• BZip2 (*.tar.bz2)
• GZip (*.tar.gz)
• Tar (*.tar)
• Zip (*.zip)


DA: GUI Instance Features
The features of the
instance for which a
snapshot is being created
are shown here

Deselect the features, or
even specific files in each
feature, that should not be
included in the snapshot


DA: GUI Instance Data
Select whether or not the
Data Spaces associated
with the instance should
be included in the
snapshot

Shows the Chunks
associated with each Data
Space and their locations

NOTE: Limited to Cooked
files only.


DA: GUI Snapshot Configuration

A summary of the
snapshot to be created is
presented

Selecting Next will begin
creation of the snapshot
with the selected features
and/or data


DA: GUI Packaging Snapshot

The progress page
shows the details of the
packaging of the
snapshot


DA: GUI Packaging Summary

The summary page
shows the result of the
snapshot creation

If DB Spaces were
selected for the
snapshot, they are saved
with the archive name
specified, with “_db”
appended to the name


DA: CMD Usage

The Command-Line
Interface can be used to
perform all the actions
mentioned before, except
select specific feature

Pass the -h (--help)
option to the
ifxdeployassist command
to view the syntax


DA: CMD Snapshot Creation

The -c option is
required to execute in
command-line mode

Once the required
options have been
provided, the snapshot
is created
automatically


DA: CMD Examples

ifxdeployassist -cvi infmx22:dana:9444 -f snapshot1.zip
Creates a snapshot of the infmx22 instance only and saves it to <current
dir>/snapshot1.zip

ifxdeployassist -cvdi informix11:dana:9344:DRDA -a TAR
Creates a snapshot of the informix11 instance and its data and saves the
following files: <current dir>/informix11.tar

ifxdeployassist -cdnf /tmp/snapshot12 -i server3:dana:9945
Creates a snapshot of the server3 instance's data only and saves it to
/tmp/snapshot12_db.tar.gzip


Deployment Utility (DU)

Deployment Utility (DU)

Deploy it.


DU: Overview
Standalone tool to rapidly deploy packaged Informix
instances in an embedded environmen

Introduced in 11.50.xC6

Configuration file: $INFORMIXDIR/etc/ifxdeploy.conf

Command line tool with customization options
during deployment
ifxdeploy
[-config <configfile>] [-clone] [-extractcmd <command>]
[-verbose] [-l <logfile>] [-p <password>] [-silent] [-sqliport <port>]
[-drdaport <port>] [-servernum <num>] [-rootpath <rootdbs>]
[-file <tgz file>] [-relocate <path>] [-force] [-keepdis]
[-start [<secs>] [-autorecommend] [-y]


DU: Typical usage
1. Install and configure a template Informix instance

2. Use Deployment Assistant (DA) to Package the
contents of $INFORMIXDIR/* and the relevant
directory containing the dbspaces, tempdbspaces,
etc.

3. Update $INFORMIXDIR/etc/ifxdeploy.conf

4. Use $INFORMIXDIR/bin/ifxdeploy to rapidly deploy
the template Informix instances on the target


DU: Configuration File
All dbspaces, tempdbspaces should reside in one directory

No support for raw devices

$ONCONFIG.autorec file is an alternate configuration file which
may require server initialization for certain parameters to come
into effect

The “-autorecommend” option leverages new technology in 11.70
which takes into account hardware performance for calculating
parameter values (for example: disk read/write speeds)


DU: Limitations/Considerations
With DU, you can use a config file ifxdeploy.conf as an
alternative to command-line arguments and
environment variables
If the same options are in the config file and on the
command line, the command line takes precedence
If the same options are in the config file and in the
environment, the config file takes precedence

A sample config file ifxdeploy.conf is included on the
Infomix server at $INFORMIXDIR/etc on Linux and
UNIX and at %INFORMIXDIR%etc on Windows.


DU: ifxdeploy.conf usage example
Deploys an instace from demo_on.tgz
Relocates data spaces to /data/demo_on
New rootpath is set to /data/demo_on/online_root
Starts the instance after deployment
Additional parameters are passed via ifxdeploy.conf
file
Prints verbose messages

./ifxdeploy -verbose -config ifxdeploy.conf -f demo_on.tgz
-rootpath /data/demo_on/online_root -relocate /data/demo_on
-start


DU: autorecommend feature
Section for “-autorecommend” option in
ifxdeploy.conf

BEGIN AUTORECOMMEND
MAXCPUS (Max number of CPUs to use, Default = 1)
MAXDISK (Max amount of disk space to use, Default = 2048 MB)
MAXMEM (Max amount of memory to use, Default = 512 MB)
MAXUSERS (Max number of OLTP users, Default = 32)
MAXDSUSERS (Max number of DSS users, Default = 4)
RTO_SERVER_RESTART (Real time objective, Default = 60 secs)
END AUTORECOMMEND

The alternate configuration file is saved as
$INFORMIXDIR/etc/$ONCONFIG.autorec

DU: Example for -autorecommend
$INFORMIXDIR/etc/$ONCONFIG.autorec will have the
calculated settings for...
Rootdbs (ROOTSIZE)
Physical log (PHYSFILE, PHYSBUFF)
Logical log (LOGFILES, LOGSIZE, LOGBUFF)
CPU parameters (MULTIPROCESSOR, VPCLASS cpu, VP_MEMORY_CACHE_KB)
AIO/Cleaners (CLEANERS, DIRECT_IO)
Locks (LOCKS)
Shared memory (SHMVIRTSIZE, SHMADD)
Online Index Memory (ONLIDX_MAXMEM)
PDQ parameters (DS_MAX_QUERIES, DS_TOTAL_MEMORY, DS_MAX_SCANS,
DS_NONPDQ_QUERY_MEM)
Logical Recovery parameters (ON_RECVRY_THREADS,OFF_RECVRY_THREADS)
Bufferpool/LRU parameters (BUFFERPOOL)

ifx_silent_deploy
Silent deployment of Informix server instance and its
data spaces is a two-step process:

– Deploy data spaces from the snapshot that was created using
DA.
– Deploy the Informix server instance, optionally relocate the
data spaces, and start the instance by using DU.

ifx_silent_deploy.sh and ifx_silent_deploy.cmd are
example scripts that show you how to perform these
tasks silently.


ifx_silent_deploy.sh usage
ifx_silent_deploy.sh <relocate_option> <srvpkg> <dbspkg>
<currloc> [<newloc>]
relocate_option - relocate to relocate data spaces; norelocate not to relocate data
spaces

srvpkg - Name of the server package

dbspkg - Name of the data spaces package

currloc - Current location of data spaces

newloc - New deployment location of the data spaces when relocating.
This argument is not required if you are not relocating data spaces.

ifx_silent_deploy.sh relocate demo_on.tgz demo_on_db.tgz
/data/IBM/demo/server /data/demo_on
