Running Trafodion
This section describes how to start Trafodion and run operations.
...
Each Time New Source is Downloaded
Start a new ssh session and set up environment:
...
.
| Code Block | ||
|---|---|---|
| ||
cd <download directory>/apache-trafodion-1.3.0-incubating |
...
source |
...
./env.sh |
...
cd $MY_SQROOT/etc |
...
# delete ms.env, if it exists |
...
rm ms.env |
...
cd $MY_SQROOT/sql/scripts |
...
sqgen |
Start
...
Trafodion
...
| Code Block | ||
|---|---|---|
| ||
cd $MY_SQROOT/sql/scripts |
...
sqstart
sqcheck |
Management Scripts
| Component | Start | scriptStop | scriptStatus | ||
|---|---|---|---|---|---|
| For all All of Trafodion | sqstart | sqstop | sqcheck | ||
| For DCS (Database Connectivity ServiceServices) | dcsstartdcstart | dcsstop | dcscheck | ||

Create Trafodion Metadata
Checking the status of Trafodion and its components
There are several health check scripts that are available which will provide the status of Trafodion. They are :
sqcheck (For all of Trafodion)dcscheck (For Database Connectivity Service)rmscheck (For RMS Server)
Create Trafodion metadata
If you started a new ssh session, be sure to
...
| Code Block | ||||
|---|---|---|---|---|
| ||||
# Ensure that the Trafodion environmental variables have been loaded. cd <download directory>/incubator-trafodion source ./env.sh |
Assumption: Trafodion is up and running, you can now start up a SQL command line interface and initialize Trafodion
sqlci Perform the following statements:
...
.
Use sqlci to create the Trafodion metadata.
| Code Block | ||
|---|---|---|
| ||
$ sqlci >> initialize trafodion; |
...
. . . >> exit |
...
;
$ |
Validate Your Installation
You can use sqlci or trafci (connects via DCS) to validate your installation.
| Code Block | ||||
|---|---|---|---|---|
| ||||
get schemas;
|
Validate
Test your setup by using "sqlci" or "trafci" (uses DCS to connect to the SQL engine):
...
create table table1 (a int); |
...
invoke table1; |
...
insert into table1 values (1), (2), (3), (4); |
...
select * from table1; |
...
exit; |
You are done and ready to go!Assuming no errors, you're installation has been successful. You can start working on your modifications.
