Under DSNREXX, one can set the isolation level with the "EXECSQL SET CURRENT PACKAGSET=" command. What is the default isolation level if this command is not issued?

Danm,

It depends on the package chosen when your shop installed DB2 REXX Language Support. The default isolation values of the packages are listed below.

Code:

Package name   Isolation level
============   ===============
DSNREXRR       Repeatable read (RR)
DSNREXRS       Read stability (RS)
DSNREXCS       Cursor stability (CS)
DSNREXUR       Uncommitted read (UR)


To change the isolation level for SQL statements in a REXX procedure, execute the SET CURRENT PACKAGESET statement to select the package with the isolation level you need. For example, to change the isolation level to cursor stability, execute this SQL statement:

[code:1:4cf8c11efd]
"EXECSQL SET CURRENT PACKAGESET=
