Oracle Tuxedo Applications Packaging and Deployment

This topic contains the following sections:

•

Overview

•	How to Deploy/Undeploy Tuxedo Applications

Overview

This feature provides a centralized control platform to allow users to automatically deploy/undeploy one Tuxedo application (domain) on different remote machines using a set of new commands on the master node of domain. Deployment process typically contains several steps: application packages distribution, Tuxedo system environment setup, Tuxedo configuration, Tuxedo system booting and so on.

Components

This feature contains the following main components:

•	Application Packages Repository

•	Deployment Repository

•	New-added Tuxedo commands tmcrdom and tmdeldom

•	Enhanced Tuxedo tlisten daemon.

The relationship among these components is illustrated in Figure 18‑1:

Figure 18‑1 Applications Packaging and Deployment Component Relationship

•	Application Packages Repository: It is a place in NFS (Network File System). Users need to maintain (add/delete) their Application Packages in this place by themselves. This place can be accessed by all the compute nodes which will be deployed the Tuxedo Application to.

•	Deployment Repository: It is a place in NFS (Network File System). This feature will maintain all the domains' information generated by this feature itself in this place. This place can be accessed by all the compute nodes which will be deployed the Tuxedo Application to.

•	New-added Tuxedo Commands: Two new added Tuxedo commands, which are responsible for creating domain, configuring domain, connecting with tlisten to do the deployment tasks and so on.

•	Enhanced tlisten daemon: This daemon will do the real deployment tasks on every compute node once it receives the Tuxedo deployment command notification.

To use this feature, first, the users need to allocate two big enough disk space or something like this to act as the Application Packages Repository and Deployment Repository on the NFS. And make sure the two places are accessible by all the Tuxedo System such as its new added commands, tlisten and so on. Second, the Tuxedo System must have been installed on every compute node which the Tuxedo Application will be deployed to. Last, you need to start up tlisten on every compute nodes. All the Tuxedo servers' running dependent libraries, such as DataBase client libraries, are not in this feature's deployment scope, it needs the customers themselves to assure their availabilities.

Constraints

This feature doesn't support to deploy machine level ENVFILE (which is specified in UBBCONFIG MACHINES section by ENVFILE parameter), groups level ENVFILE, servers level ENVFILE, servers level RCMD file to other directories than APPDIR.

The JAVA JDK has been installed on the master node on which will run the tmcrdom command.

How to Deploy/Undeploy Tuxedo Applications

Introduction to Application Package Organization and Contents

A Tuxedo application (domain), as defined in a TUXCONFIG (UBBCONFIG) configuration file, is the set of machines, groups, servers, and other resources. It can exist on a single machine or cross multiple network-connected machines. For this feature, to deploy the whole Tuxedo application, users need to add their Application Packages to the Application Packages Repository by themselves first. One Application Package is an entity which holds all the binary or non-binary files referenced by one or more groups defined in a UBBCONFIG file. That means, every Application Package is mapped to one or more groups defined in a UBBCONFIG file, and all these groups must belong to the same machine in UBBCONFIG. So a Tuxedo application can consist of one or more application packages. Also every Application Package can be repeatly deployed to one or more domains.

The application package is a user generated .zip file and can have several tiers in it. For example:

Figure 18‑2 Application Package

Every Application Package is required to contain a file named "Properties.xml" in Tier1. This file is a group level's part UBBCONFIG file. It contains some properties in GROUPS, RMS, SERVERS, and SERVICES sections of a complete UBBCONFIG file and is mainly used to describe the relationship and parameters of all the servers within this package's groups. The Properties.xml file will be used to generate the ultimate UBBCONFIG file when decide to deploy this package to a machine using tmcrdom and its content can be modified in the according deployment plan.

All the items in the GROUPS, RMS, SERVERS, SERVICES section of UBBCONFIG are divided into four categories:

•	Mandatory and Changeable. It is a kind of index value. The user must fill it in the Properties.xml file, but it will be replaced by the value specified in the deployment plan when using tmcrdom command.

•	Optional and Unchangeable. If needed, it must be filled by the user in the Properties.xml file. And it will not allow to modify it when assemble the UBBCONFIG. That means, this kind of parameter can only appear in the Properties.xml if needed, and can not appear in the deployment plan.

•	Mandatory and Unchangeable. It must be filled by the user in the Properties file, and its value will not be modified when assemble the UBBCONFIG.

•	Forbidden. It can't be filled in the Application Packages' Properties.xml file. The user will fill it in the deployment plan when assemble the UBBCONFIG if needed.

In the Properties.xml file, users must assure all the parameters' references are valid. For example, the GROUP which is indicated by SRVGRP in the SERVICES section must have already been defined in this Properties.xml file's GROUPS section or it will report error when system generates the UBBCONFIG.

Besides the items of the GROUPS, RMS, SERVERS, SERVICES section of UBBCONFIG in Properties.xml, this file also contains some package global attributes at the beginning:

 

Table 18‑5 Description Information of the Package

Item	Description
PackageName	The global unique application package name, for example, APP1.zip.
TuxedoVersion	The Tuxedo version this package is built on. This item is checked when assembling Tuxedo domain to decide if the package is suitable for certain Tuxedo installation.
SupportedOS	The Operation System this package can be deployed to. This information is compared with the corresponding item in Machine list entry when deploying the package. The possible values are Linux, SunOS, AIX, and HP-UX.
TuxedoWordSize	The Tuxedo word size this package is built on. The value can be 32 or 64 (bit). This information is compared with the corresponding item in Machine list entry when deploying the package.
MachineArch	The machine architecture this package can apply to. The possible values are: x86_64, SUNW, powerpc, and IA64. This information is compared with the corresponding item in Machine list when deploying the package.
LibPath	The path where the library locates in the package, if there is a library in it.

Actually the values of these package global attributes will not be checked by Tuxedo tmcrdom/tmdeldom commands. The reason to keep these values in the Properties.xml is that, the contents requirement of the Application Package are the same with the similar Tuxedo EM function. So we suggest you to fill these values as the table described, then when you want to use the Tuxedo EM deploy/undeploy function, you can use these packages directly without any change.

For more information, please refer to Properties.xml Schema.

Uploading/Deleting an Application Package

User can add/delete the Application Packages to/from the Application Package Repository freely by themselves. That means it's the users' duty to maintain the Application Packages Repository.

Creating and Deploying a Domain

Users need to use tmcrdom to create and deploy the domain. This command must be run on the master node of the domain which will be created by this command.

Before running this command, the customer need to export their JAVA_HOME and JVMLIBS environment.

The command syntax is:

tmcrdom -d "domain_name" -f "deployment_plan"

Where:

•	"domain_name" will be checked. If the domain has already existed in the Deployment Repository, it will report error, or it will create this domain in the repository.

•

"deployment_plan" is a text file. This feature assumes that it has already been created by the customer before invoking this command. It contains the deployment information needed by this domain. It can be specified in the command as an absolute path or relative path on the master node. Its format is similar to UBBCONFIG.

Note:

In some scenarios, although tmcrdom execution fails, it actually has created a domain in the Deployment Repository, thus if you create the domain again you will receive an error message saying the domain already exists. To solve this, you need to delete the domain using the tmdeldom command with -f option before you can create the domain.

deployment_plan

A deployment_plan file is made up of nine possible specification sections. Allowable section names are:

•	RESOUCES Section

•	MACHINES Section

•	GROUPS Section

•	RMS Section

•	NETGROUPS Section

•	NETWORK Section

•	SERVERS Section

•

All other parameters are same as RESOURCES section parameters in UBBCONFIG.

MACHINES Section

It's same as the UBBCONFIG's MACHINES section. It must be included in the deployment plan. Its contents will be used as the MACHINES section in the ultimate UBBCONFIG.

Besides these, this feature introduce some new parameters:

CONFIGSCRIPT = string_value[0..256]

It specifies the configuration script which will be run on each compute node before booting the Tuxedo System. It must be an absolute path on the master node. The tmcrdom command will copy this script to the deployment repository specified by DEPREPOSITORY and deploy it to the destination machine later. After deployed to the destination machine, it will be run under the destination machine's APPDIR.

BOOTSCRIPT = string_value[0..256]

It specifies the booting script which will be run on the mater node to boot the Tuxedo System. It must be an absolute path on the master node. The tmcrdom command will copy this script to the deployment repository specified by DEPREPOSITORY and deploy it to the destination machine later. After deployed to the destination machine, it will be run under the destination machine's APPDIR.

SHUTDOWNSCRIPT = string_value[0..256]

It specifies the shutdown script which will be run on the mater node to shutdown the Tuxedo System. It must be an absolute path on the master node. The tmcrdom command will copy this script to the deployment repository specified by DEPREPOSITORY and deploy it to the destination machine later. After deployed to the destination machine, it will be run under the destination machine's APPDIR.

UNCONFIGSCRIPT = string_value[0.. 256]

It specifies the unconfigure script which will be run on each compute node after the Tuxedo System is shutdown. It must be an absolute path on the master node. The tmcrdom command will copy this script to the deployment repository specified by DEPREPOSITORY and deploy it to the destination machine later. After deployed to the destination machine, it will be run under the destination machine's APPDIR.

For every machine, machine address, LMID, TUXCONFIG, TUXDIR and APPDIR are required. For master machine, CONFIGSCRIPT, BOOTSCRIPT and SHUTDOWNSCRIPT are required. For slave machine, BOOTSCRIPT and SHUTDOWNSCRIPT are forbidden.

Note:

The scripts specified by CONFIGSCRIPT, BOOTSCRIPT, SHUTDOWNSCRIPT, and UNCONFIGSCRIPT must be able to be found by tmcrdom on the master machine where the command runs.

These parameters below are new for the Optional parameters:

PAKNAME = string_value[0..256]

It associates this group with one Application Package. That means, this Application Package will be deployed to the machine which is specified by this group's LMID parameter. If PAKNAME parameter is specified, the GROUPS parameters which can be specified in the properties.xml file like:ENVFILE, TMSNAME, MRM, SIGNATURE_REQUIRED, ENCRYPTION_REQUIRED can't appear in this group definition in the deployment plan, their values will come from the Application Package's properties.xml file. If PAKNAME is not specified, this group is a normal one. Then all the parameters in this group will be the same with the UBBCONFIG. We recommend the customers to use this normal group to hold their Tuxedo System level servers, for example, GWADM.

If PAKNAME is specified, PAKGRPNAME and PAKINSTANCE must also be specified for this group entry.

PAKGRPNAME= string_value [1..30]

It specifies the logical name of the group in the Application Package, and the Application Package's name is specified by PAKNAME parameter. It cannot contain an asterisk (*), comma, or colon. If a non-empty value is specified, PAKNAME and PAKINSTANCE must also be specified for this group entry. Two group entries with the same PAKNAME and PAKINSTANCE cannot have the same PAKGRPNAME. That means two group entries cannot be associated with one same group entry in one Application Package.

PAKINSTANCE = number [1...30000]

It specifies the index for the same Application Package. This is for the situation that one Application Package being deployed to the same domain for more than once. This number must be greater than 0 and less than 30000. If PAKINSTANCE is specified, PAKNAME and PAKGRPNAME must also be specified.

This command will generate one domain's all information including UBBCONFIG and save it to the Deployment Repository.

This command will configure every compute node according to the configure script including creating the TLOG device and so on.

This command will boot the whole Tuxedo System.

Undeploying a Domain

Users can use tmdeldom to shut down and undeploy the domain. This command must be run on the master node of the domain.

The command syntax is:

tmdeldom -d "domain_name" -r "deprepository" -f

The command functions are:

•	Shut down the whole domain.

•	Unconfigure every node if needed.

•	Undeploy the whole domain and delete it also from the Deployment Repository.

The parameter domain_name is the domain's name which is specified in the previous tmcrdom command. The deprepository is the Deployment Repository which is specified by the DEPREPOSITORY parameter in the previous deployment plan.

Without "-f", once any step of tmdeldom fail, the command will not continue to execute.

If -f is specified, even if step 1, 2, or 3 is failed, this command will also delete the domain information in the repository.
