(ZOS) Dump control settings

Use these settings to manage the dump control configuration in WebSphere Application Server.

ras_dumpoptions_dumptype= n

Default dump used by the signal handler. Valid values and their meanings are:

• 0

  No dump is generated.

• 1

  A ctrace dump is taken.

• 2

  A cdump dump is taken.

• 3

  A csnap dump is taken.

• 4

  A CEE3DMP dump is taken.

  CEE3DMP dumps are not available in WAS for z/OS with 64-bit support. If this option is chosen, it will be ignored in 64-bit environments.

  CEE3DMP generates a dump of Language Environment and the member language libraries. Sections of the dump are selectively included, depending on dump options specified, either by default or through the

   ras_dumpoptions_ledumpoptons
  

  variable. By default, this value passes

   THREAD(ALL) BLOCKS
  

  to CEE3DMP. We can override the default options for CEE3DMP through the

   ras_dumpoptions_ledumpoptons
  

  variable. For more information about CEE3DMP and its options, see z/OS Language Environment Programming Reference, SA22-7562..

Default: 3

Example:

 ras_dumpoptions_dumptype=2

ras_dumpoptions_ledumpoptons= options

Specifies dump options to be used with a CEE3DMP. If we want more than one option, separate each option with a blank. Specifies dump options to be used with a CEE3DMP. If we want more than one option, separate each option with a blank.

This WebSphere variable is used only when we specify

 ras_dumpoptions_dumptype=4

. For an explanation of CEE3DMP and valid dump options, see z/OS Language Environment Programming Reference, SA22-7562.

Rule: The maximum length of the option string on this environment variable is 255. If the option string is longer than 255, we receive message BBOM0011W and the CEE3DMP dump options are set to

 THREAD(ALL) BLOCKS

.

Default:

 THREAD(ALL) BLOCKS

Example:

 ras_dumpoptions_ledumpoptons=NOTRACEBACK NOFILES
