Download of Product Binaries
30
----------------------------
31
For deploying IBM DB2 charm the user needs to download the correct package as mentioned in the `Usage` section and host it on an SFTP or Web server. The IBM DB2 charm will connect to the server(either by SFTP or HTTP method) to download and deploy the same. The host server can be any Power Ubuntu/X86 Ubuntu servers and should be copied into a directory structure as below
33
`/<path to charm dir>/charm/repository/<productname>/<package.tar>`
35
The complete path where the package is stored is a configurable item which needs to be configured before deploying the charm.
38
Memory and Disk Requirements
39
----------------------------
40
At a minimum, a DB2 database system requires 256 MB of RAM. For a system running just a DB2 product and the DB2 GUI tools, a minimum of 512 MB of RAM is required. However, 1 GB of RAM is recommended for improved performance.
42
On Linux and UNIX operating systems, 2 GB of free space in the /tmp directory is recommended. Please make sure this minimum memory configuration is available before deploying the charm. More information on this can be found in [Memory Requirements][db2-memory-disk-requirement]
46
To deploy DB2 charm, run the following command:
48
1. Make sure the appropriate memory requirements are made available
50
2. For deploying either use an existing machine, or create a new machine using
53
juju deploy --to <machine number> --repository=<path_to_charms_folder> local:trusty/ibm-db2
55
3. Set all required config values like the curl__opts to log into the host machine and curl_url which specifies the url to download the packages, by using juju set command. To provide these run the following command:
57
juju set ibm-db2 curl_opts=<login credentials>
58
juju set ibm-db2 curl_url=<url to download package?shavalue>
62
juju set ibm-db2 curl_opts="-u user:password"
63
juju set ibm-db2 curl_url="http://<ipaddress>/debs/ibm-db2/DB2_Svr_10.5.0.3_Linux_x86-64.tar.gz?sha512=ae20be99e3cd2cef24d53a28331871d7193cfc7f7c24c580e6e78dc58c9ffb364cbcc69cb3773d2f0135b8c9be7ee40a7dc4e09fec0a4d731c4864bbba87d31e"
65
The command to find the checksum value is `sha512sum <Package Name>`
67
In the above example sha512 is used, you can use sha256 or md5 as well.
68
Also in the above example, the packages are hosted on webserver, so http protocol is used, if you have placed the packages on sftp server, then replace the protocol with sftp.
70
4. At this point DB2 install will wait for you to accept the License. To install the downloaded binaries you must agree to the IBM license. The license file(s) can be found in the product binaries you downloaded.
72
If you agree to the license, run the following command :
74
juju set ibm-db2 license_accepted=True
77
Juju deploy command will install db2 and will expose the hostname, port number, db2 instance, install path and userid to the users.
80
Uninstallation of IBM DB2
81
---------------------------
83
Setting the license_accepted to False will uninstall the product.
85
juju set ibm-db2 license_accepted=False
87
Additional configuration parameters
88
-----------------------------------
90
Following shows the different configurable values for ibm-db2 charm:
92
* If the user wants to set a different file path used to create databases and logs it can be set using the config value dftdbpath. Use the following command to set it
94
juju set ibm-db2 dftdbpath=<new-path-to-set>
98
juju set ibm-db2 dftdbpath="/tmp"
101
Installation Verification
102
------------------------
103
Once IBM DB2 charm is deployed, the user can log into the container/machine where it is deployed using the default user/password (db2inst1/db2inst1). The user can run any db2 commands after this.
105
* For creating a new DB the user may run the command:
107
db2 create database <db-name>
109
* For listing the DBs created, run the command:
111
db2 list db directory
113
* For getting db2 command prompt just run the command:
117
Relating with other consumer charms
118
----------------------------------
119
IBM DB2 charm can be related to other consumer charms using the following command.
121
juju add-relation ibm-db2 <consumer-charm>
123
When IBM DB2 charm is related to any consumer charm, it creates a db2instance, username/password as per the service name and will be provided to the consumer charm. IBM DB2 charm also creates DBs as provided by the consumer charm and returns the DB details once they are successfully created. The following code will help the consumer charm authors to pass the DB names to the IBM DB2 charm:
126
function configure_dbs(){
128
relation_call --state=db.connected set_dbs $dbnames || true
131
If no DB name is provided by consumer charm, IBM DB2 charm by default creates DBs according to the service name.
133
Also to set relation with IBM DB2 charm and make use of all the features, the consumer charm __should__ pass the ssh key from itself to IBM DB2 charm. The following code will help the consumer charm authors to do this :
136
@when_not 'test.sshconfigured'
137
function configure_sshkeys(){
139
if [ ! -f $SSH_PATH/id_rsa.pub ]; then
140
juju-log "Setting up SSH keys."
141
ssh-keygen -t rsa -f $SSH_PATH/id_rsa -N ''
143
key="`cat $SSH_PATH/id_rsa.pub`"
144
relation_call --state=db.connected set_ssh_keys $key || true`
145
set_state 'test.sshconfigured'
148
Without this IBM DB2 charm will not be ready and will not create the DBs for the related services.
152
See config.yaml file for more information.
154
* `license_accepted`: True to accept license. Before you can use or install IBM DB2, you must accept the terms of International License Agreement for Non-Warranted Programs and additional license information. Please read the license agreement carefully. The license file(s) can be found under the server/db2/license directory after downloading and extracting IBM DB2 there. Set the value of license_accepted to True if you agree to IBM DB2 license.
156
* `dftdbpath` : This parameter contains the default file path used to create databases under the database manager. If no path is specified when a database is created, the database is created under the path specified by the dftdbpath parameter.
158
* `curl_url` : Location of the IBM product installation file(s). This should be a URL that curl can use to download files. Multiple URLs should be separated by a space.
160
* `curl_opts` : The options passed to the 'curl' command when fetching files from curl_url.

##### Enabling BLU acceleration for DB2 Advanced Enterprise Server Edition/DB2 Advanced Workgroup Server Edition
167
The same DB2 charm(DB2 Enterprise Server Edition) can be extended to enable the BLU acceleration(DB2 Advanced Enterprise Server Edition/DB2 Advanced Workgroup Server Edition) by following the below section. The DB2 charm has to be deployed first and then few settings need to be done to enable the BLU feature.
169
To upgrade DB2 Enterprise Server Edition (DB2 ESE) to DB2 Advanced Enterprise Server Edition(DB2 AESE) or DB2 Advanced Workgroup Server Edition (DB2 AWSE) the user need to accept the license for the same. Run the following command for accepting the AESE/AWSE license which the user procures on buying the Advanced Enterprise/ Workgroup Server Edition product. The user needs to log in using the configured user name/password to run the below commands.
171
db2licm -a </path/to/license/file/db2aese_u.lic>
173
db2licm -a </path/to/license/file/db2awse_u.lic>
175
`db2licm -l` command will show the license details once you apply the license.
176
Now to enable the BLU feature the DB2_WORKLOAD registry variable has to be set to ANALYTICS and then the DB has to be restarted. The following commands will help the user for this.
178
db2set DB2_WORKLOAD=ANALYTICS
182
To test that DB2 AESE with BLU acceleration is enabled run the following command:
184
db2 create database <test-db>
185
db2 connect to <test-db>
186
db2 get db cfg | grep DFT_TABLE_ORG
188
The output Default table organization (DFT_TABLE_ORG) = COLUMN confirms that the DB2 AESE/AWSE with BLU is enabled. If the pre requisites for DB2 for AESE/AWSE is not set (accepting the proper license and setting the registry variable DB2_WORKLOAD) the above command would return Default table organization (DFT_TABLE_ORG) = ROW. Column-organized tables store each column on a separate set of pages on disk. Organizing data by column on disk reduces the amount of I/O needed for processing queries because only columns that are referenced in a query need to be accessed.
190
Once this is set all the tables created will be by default COLUMN organized whereas without BLU acceleration the tables will be ROW organized. Also without proper license we cannot create COLUMN organized tables. Once we enable COLUMN organized tables, we can create either ROW enabled or COLUMN enabled tables using the option ORGANIZE BY ROW or ORGANIZE BY COLUMN while creating the tables by running the below commands from db2 command prompt.
192
create table sales_row(tid integer not null, prod_name varchar(30)) ORGANIZE BY ROW
193
create table sales_col(tid integer not null, prod_name varchar(30)) ORGANIZE BY COLUMN
195
The following command will convert the ROW organized tables to COLUMN organized if the proper license is accepted. Without having valid license the following command will error out.
197
db2convert -d <test-db>
199
