The ClientApplName keyword is used
to set the client application name that is sent to a database. Applications
that do not specify the application name by default can use the ClientApplName keyword
to provide the client application name.
- db2cli.ini keyword syntax:
- ClientApplName = application name
- Default setting:
- None
- Applicable when:
- Connected to a database with an IBM® Data
Server product.
- Equivalent environment or connection attribute:
- SQL_ATTR_INFO_APPLNAME
- Usage notes:
- The CLI driver
has limit of 255 characters for the ClientApplName keyword.
Database
servers enforce different limitation in the length of the value and
can truncate it. Note the following conditions:
- DB2® for z/OS® Version
11 servers in new function mode (NFM) support a length of up to 255
characters for the CURRENT CLIENT_APPLNAME special register.
- DB2 for z/OS servers
remove trailing spaces that are specified in the ClientApplName keyword
value.
- DB2 for z/OS Version
10 and earlier servers support a length of up to 32 characters.
- CLI applications
can set the ClientApplName keyword on DB2 for i V6R1
and later servers. DB2 for i servers
support a length of up to 255 characters.
To ensure that the data is converted correctly when transmitted
to a host system, use only the characters A - Z and 0 - 9 and the
underscore (_) or period (.).
For connection to DB2 for z/OS servers,
the ClientApplName keyword is replayed upon connection
failover when the automatic client reroute (ACR) feature and the workload
balance (WLB) feature are enabled.
A
client sends the default client information register values to the DB2 for z/OS server
when they are not explicitly set by the user. The default CURRENT
CLIENT_APPLNAME special register value is the current process
name. The SQLGetConnectAttr() function and the sqleqryi API
can return the default value only when the enableDefaultClientInfo keyword
is set to True in the IBM data
server driver configuration file.
