Object EVAR Commands

SQL/MX Connectivity Service Administrative Command Reference—526350-005

6-4

Considerations—ADD EVAR

PREFIX string

is the portion of the object definition that appears before the name. It is an SQL

string literal and so requires single quotes. The default value is determined by the

type. See EVAR Types on page 6-1. For consistency, this value is displayed in

uppercase letters, even though it is a quoted literal.

VALUE string

is the portion of the object definition that appears after the name. It is an SQL

string literal, and so requires single quotes. There is no default. See the SQL/MX

Reference Manual for name and value syntax details.

LIMIT number

is the threshold value for the monitored attribute for this resource management

policy. There is no default. This value must be positive and not exceed the

maximum value of the LARGEINT SQL data type of 9,223,372,036,854,775,807.

Note that the number entered should have no commas and should appear as

9223372036854775807. Commas are inserted only for clarity.

ACTION key-val

is the desired action when the limit is exceeded for this resource management

policy. The valid values are LOG, LOG_WITH_INFO, and STOP (with LOG also).

The LOG option is the default.

Considerations—ADD EVAR



ADD EVAR is a sensitive command.



The asterisk (*) wild card is not supported for evar-name.



ADD EVAR fails if you use the same name in an existing EVAR of the same type.



The new EVAR is added after existing ones of this type. If order is important, see

EVAR Order on page 6-2.



All SERVICEs can detect the added EVAR on the DS as soon as it is created, but

connected servers do not detect it until the current connection is closed.



You need not stop the DS to execute ADD EVAR.



Names for some EVARs must be multiword to be unique, so blank spaces are

permitted in this name with double quotes. The resulting definition consists of the

prefix, name, and value fields, concatenated together in that order.

Example—ADD EVAR

This example adds an EVAR of type define with the name GROUP to the DS

TDM_Default_DataSource. You can use the equal (=) sign in the name, but it is not

1 2 ... 75 76 77 78 79 80 81 82 83 84 85 ... 102 103
