Oracle TSAM Plus on Docker

Sample Docker build files to facilitate installation, configuration, and environment setup for DevOps users. This image has also been certified with Oracle Container Cloud Service (OCCS). For more information about Oracle Tuxedo System and Applications Monitor Plus (TSAM Plus) please see the Oracle TSAM Plus Online Documentation.

This project offers Dockerfile for building:

  • Oracle TSAM Plus 12c Release 2 (12.2.2)

Dependencies

This project depends on the Oracle Server JRE 8 Docker Image. So, before you proceed to build this image, make sure the image oracle/serverjre:8 has been built locally or is accessible in a remote Docker registry.

IMPORTANT: You will have to provide the required installation binaries and put them into the dockerfiles/<version> folder.

For this image following installation media / binaries are required:

The download links and md5sum of downloaded binaries could also be found in the .download files inside the dockerfiles/<version> folder. Note that the downloaded file names must NOT be changed, they should remain the same with the file names mentioned in the .download files.

Building Oracle TSAM Plus Docker Install Images

Once you have provided the installation binaries and put them into the right folder (dockerfiles/<version>), go into it and run:

docker build -t oracle/tsam:12.2.2 .

Since during the image building new packages required by this image will be installed by the yum repository manager, access to internet should be available. If you are building the image behind a HTTP proxy server, use below command:

docker build \
   --build-arg http_proxy=http://<hostname>:<port> \
   --build-arg https_proxy=http://<hostname>:<port> \
   -t oracle/tsam:12.2.2 .

It is recommended to give read permission to all users on the downloaded binary files before building the image. Otherwise the resulting image will most probably get 1.7G larger.

IMPORTANT: The resulting image will be an image with the Oracle TSAM Plus 12.2.2 installed. On first startup of the container a new Oracle WebLogic domain will be created, followed by which the TSAM Manager application will be deployed into the domain.

Applying Rolling Patch to the Base Image

By building the Docker image with the primary Dockerfile in the dockerfiles/<version> directory, you got an image with corresponding TSAM GA release installed. If you are a supported customer of Oracle TSAM Plus, you'll be able to download and apply rolling patches to the base installation to benefit from the latest product enhancements and bug fixes.

To build the Docker image with rolling patch applied, check the sample in samples/apply-patch directory for more detail.

Running Oracle TSAM Plus in a Docker container

The TSAM Manager application relies on a remote Oracle Database to run. So, on starting of the container, the required information need to be passed into the container by a set of environment variables, e.g. The database connection string, credentials, table space, Oracle WebLogic domain admin password, etc. The easiest way to do this is through the docker-compose command. For more information about docker-compose, check the Docker Compose online documentation.

Running Oracle TSAM Plus with new TSAM database schema created

This is the typical scenario to use the Docker image. By providing the new Oracle Database instance connection information and the sys user credentials, the entire TSAM database schema will be created on initializing the container.

A sample docker-compose.yml file is as below:

version: "2"
services:
  tsam:
    image: oracle/tsam:12.2.2
    hostname: tsam.docker
    ports:
      - 7001/tcp
      - 22/tcp
    privileged: true
    environment:
      - "DB_CONNSTR=db.box:1521/orcl"
      - "DB_TSAM_USER=tsam"
      - "DB_TSAM_PASSWD=tsam"
      - "TSAM_CONSOLE_ADMIN_PASSWD=admin1"
      - "DBA_USER=sys"
      - "DBA_PASSWD=welcome1"
      - "DB_TSAM_TBLSPACE=users"
      - "WLS_PW=weblogic1"

The environment variables are explained as follow:

  • DB_CONNSTR The Oracle Database instance connection string, in the format of <hostname>:<port>/<svcname>. When using the database instance provisioned by Oracle Database Cloud Service, it is the Connect String in the Database section on the instance home page. Please pay attention that the last part <svcname> is the service name of the database instance, other than SID.
  • DB_TSAM_USER The new database user to be created. Please note if the user has already been existed in the database instance, and also the followed DB_TSAM_PASSWD is correctly provided, this user will be used as the TSAM database user directly without re-create or overwrite.
  • DB_TSAM_PASSWD The password of the TSAM database user.
  • TSAM_CONSOLE_ADMIN_PASSWD The password of TSAM Manager console admin user. On successful initializing of the TSAM container, the TSAM console should be available at http://<container_ip_address>:<wls_adm_svr_port>/tsam. On the TSAM console login page, user name admin and this password will be used as the login credential.
  • DBA_USER The Oracle Database DBA username, typically it's sys.
  • DBA_PASSWD Password of database sys user.
  • DB_TSAM_TBLSPACE The tablespace in which the new TSAM database user will be created. For testing purpose, it would be OK to just use the users tablespace.
  • WLS_PW The admin user password of new created Oracle WebLogic domain.

To start the container, simply run below command in the same directly where above docker-compose.yml file resides.

docker-compose up

When running the container in a Oracle Container Cloud Service instance, just paste above docker-compose.yml file content into the YAML tab of the Service Editor on creating a container service.

Besides the above environment variables which are required, there are also some optional ones could be used to provide more control on the container.

  • DEBUG_MODE Whether or not to turn on debug mode. The value is either true or false (default). When the debug mode is turned on, more debug messages will be printed out to the container stdout. For example, the passed in environment variables and corresponding values, the Oracle WebLogic domain startup log, etc. Furthermore, when debug is on, the container will never terminate even though error is occurred during the container initialization. While in the normal mode, the container terminates after 120 seconds on failure.
  • DB_ENABLE_PARTITION Whether or not to enable the Oracle Database Partitioning feature. The value is either yes or no (default). Please note only when a Oracle Database Enterprise Edition is being used, the database partitioning could be turned on. So for a Standard Edition or XE database, the value could only be no.
  • ADMIN_PORT The new created WebLogic domain Admin Server HTTP listening port, default is 7001.
  • ADMIN_SSL_PORT The new created WebLogic domain Admin Server HTTPS listening port, default is 7002.
  • WLS_USER The new created WebLogic domain admin user name, default is weblogic.
  • DOMAIN_NAME The new created WebLogic domain name, default is tsamdomain.

Running Oracle TSAM Plus with an existing TSAM database schema

When an existing TSAM database is used for the TSAM Manager application, there will be no need to provide Oracle Database sys user related credentials. The docker-compose.yml looks like below:

version: "2"
services:
  tsam:
    image: oracle/tsam:12.2.2
    hostname: tsam.docker
    ports:
      - 7001/tcp
      - 22/tcp
    privileged: true
    environment:
      - "DB_CONNSTR=db.box:1521/orcl"
      - "DB_TSAM_USER=tsam"
      - "DB_TSAM_PASSWD=tsam"
      - "TSAM_CONSOLE_ADMIN_PASSWD=admin1"
      - "WLS_PW=weblogic1"

Note that the existing database schema used should be created by a TSAM Plus Manager installation with the same patch level, or else the application could behave abnormally.

Running Oracle TSAM Plus with an database Docker container

If you got an Oracle Database Docker image, you can run it together with the TSAM container to provide the database service. The docker-compose.yml file will look like this:

version: "2"
services:
  db:
    image: oracle-database-image
    hostname: db.box
    ports:
      - 1521/tcp
  tsam:
    image: oracle/tsam:12.2.2
    hostname: tsam.docker
    ports:
      - 7001/tcp
      - 22/tcp
    environment:
      - "DB_CONNSTR=db.box:1521/orcl"
      - "DB_TSAM_USER=tsam"
      - "DB_TSAM_PASSWD=tsam"
      - "TSAM_CONSOLE_ADMIN_PASSWD=admin1"
      - "DBA_USER=sys"
      - "DBA_PASSWD=welcome1"
      - "DB_TSAM_TBLSPACE=users"
      - "WLS_PW=weblogic1"
  links:
      - db:db.box

Changing the database connection information to a running TSAM application

The Oracle Database connection is managed in the Oracle WebLogic domain, under the datasource named tsamds. The TSAM application itself does not hold any database connection specific information, instead refers to the database through a JNDI named jdbc/tsamds.

So, to make the TSAM application connect to another Oracle Database, login to the Oracle WebLogic admin console, which should be running at http://<container_ip_address>:<wls_adm_svr_port>/console (or http://<host_ip_address>:<mapped_wls_adm_svr_port>/console), then change the database connection information under the datasource tsamds, followed by a restart of the TSAM application named tsam_wls12c.

Note that the targeting database instance should contain the whole TSAM schema of a matching version. If no valid database schema could be used, the TSAM application will fail to restart.
