CLIENT_LABEL environment variable

Set the CLIENT_LABEL environment variable in CSDK or JDBC client to assign a character string to CSDK or JDBC client session and identify that character string on the database server. You use this for environments where same userid runs multiple instances of the same application, and there is a need to distinguish one session from the other.

1  select * from sysenvses where envses_name = CLIENT_LABEL

CSDK Example

Suppose the CLIENT_LABEL is set to two different strings and the same esqlc program is executed with the session ids being 43 and 201:

bash-3.2$ export CLIENT_LABEL='csdk_client1'
bash-3.2$ ./myesqlc 

bash-3.2$ export CLIENT_LABEL='csdk_client2'
bash-3.2$ ./myesqlc

Environment for session 43:

JDBC Example

Suppose the CLIENT_LABEL is set to two different strings in the JDBC connection URL and the same JDBC program is executed with the session ids being 232 and 234:

java myjdbc "jdbc:informix-sqli://myhost:52220:user=myuser;password=mypasswd;CLIENT_LABEL=jdbc_client1"

java myjdbc "jdbc:informix-sqli://myhost:52220:user=myuser;password=mypasswd;CLIENT_LABEL=jdbc_client2"
