  AUG 14, 2017  Administrator, Business Works, interview, questions, TIBCO

Basic question and answers

1. How we can do the FT and LB enable in without using Admin Console?

Update the field “IsFT” to ‘true’ in application configuration.xml to enable Fault Tolerance Update the
field “IsFT” to ‘false’ in application configuration.xml to enable Load Balancing and deploy the application using Appmanage

2. How to enable logging of information for all activities in a project to be deployed in Administrator?

a) In admin console go to running instance –>select tracing –> configure tracing –> check the “All Activities” checkbox enabled, then save
Note: Administrator must have superuser privileges in the UNIX box to perform this action.
b) We can enable tracing property in applicate tra file by setting below 3 properties to true. If you need advance tracing, you can add input-output tracing as well which will log the input and output of each activity.

/* Basic tracing properties*/
Trace.Log=true
Trace.Startup=true
Trace.Task.*=true

/* For input and output tracing */
bw.engine.showInput=true
bw.engine.showOutput=true

3) How to make the configuration changes available permanently for all the application which going to deploy in the domain?

In Application.tra do the changes in bwengine.tra file also. Usually for each deployment the Application;.tra wash out and replace with new one with default values.

4) How to extend the validity of the self-signed certificate by another 2 years?

Make use of keytool provided by Java to increase the validity of self-signed certificates Command: “keytool -selfcert -v -alias server -validity 730 -keystore teststore.jks -storepass
mypassword”.

5) How to find the list of ports currently used by other applications?

netstat –a

6) How to handle following error message displayed in Tibco Administrator Error message: “No matching software for service archive Process Archive. The service is disabled”?

Process Archive was deployed in a machine the Business Works runtime engine has not been installed. Make sure Business Works Engine is installed on the machine where PAR file is going to be deployed. You can add Tibco Active Matrix Business works machine using “Add to additional machines” option in Tibco Administrator.

7) Maximum no of the process that can be loaded into memory can be set using?

Using Max Jobs at.Par level Advanced Tab in Tibco Admin.

8) How to modify GV after the .ear file is deployed?

By adding the property in the Application.tra file ( But not recommended)

9) What are the two fault tolerance options supported by Tibco admin.?

Fail Back and Failover

10) What is the Global variable used for pointing the certificate location?

%%BW_GLOBAL_TRUSTED_CA_STORE%%

11) Whenever Tibco administrator configuration is corrupted how to get it back.

Need to restore it back to the last successful configuration date. Usually, it will get corrupted when we have RV communication issues between the admin and the BW machine or because of some deployment issues. if we have the back up of SYS_<DOMAIN-NAME>.dat file, we can simply replace it. or else we can contact tibco suport and they will be able to remove the bad entry from the mentioned file.

12) When we make some changes in the global variables of any adapters deployed on a server and trying to redeploy it again faced some issues like On admin GUI at deployed configuration we see Server plugin failed. What needs to be done in such scenarios?

When we try to do the same we can see server plugin failed for whatever the updates we does for the adapter. So here we need to bounce/stop and restart the administrator domain on which we have deployed the adapter and even have to bounce the Hawk agent on that Server.

13) When we are trying to deploy an EAR file on Administrator sometimes we may face an issue : deploying it.

For these kinds of scenarios mostly we will be bouncing the Administrator and Hawk agent. This may/may not work sometimes. In case it doesn’t work we need to remove/delete the temp files created (if windows we can find them in .TIBCO directory in C drive, if it is unix server we can see them in the \usr\tmp directory) and restart the
administrator.

14) What is the advantage of scripted deployment in Tibco and how it differs then normal deployment?

Below are the scenario:
1. Whenever the TIBCO Administrator is down we have to deploy the application from TRA -&gt; Appmanage.
2. In case we have to deploy various applications using the same global parameters, we have to provide
every time these parameters in TIBCO administrator wile deployment. In such case its better to get a
best practice to deploy application from backend using the scripts.

Below are the advantages:
1. If Admin is down we are able to deploy the application
2. We use a properties file (XML) which is having all the variables which can be used by various similar
Applications. Hence, the similar domain can be created fast.
