I have two questions, the first concerns the Master Catalog error needing Update authority. 

I can request Update authority to the Master, but wanted to check to see if I should define an alias in a user catalog for the WEB client.  It tried to allocate:  CAVANTWC.JVM.CAVANTWC.D201202.T073229.X001  - but the CAVANTWC alias is currently not defined.  Is there a parm setting that I need to update for this high level qualifier?

Second question:  Is there a way that I can direct/define a dedicated CA Vantage Web Client  directory instead of using the TEMP directory for the LPAR (/tmpSYSC ) ?   My concern is that this temp directory is used by everyone on this lpar.

 

Environment

Release : 14.0

Component : CA Vantage Storage Resource Manager

Cause

Concerning question #1, the Vantage Web UI STC does not have UPDATE access to the Master catalog which is causing the error.

Concerning question #2, the target directories can be re-defined to specific locations by the user, thus potentially avoiding 'out of space' errors involving Java dumps.

Resolution

If the Web client tries to allocate a data set for which there is no alias, then the STC userid will need to have update authority to the Master catalog. The CAVANTWC STC userid should have access to an alias defined in a Usercat for those data sets.

Also, normally the java dumps are stored in the current working directory of the JVM. If for some reason the dump cannot be stored in this directory, then the JVM will look for the temp directory. This can be controlled by setting a variable in the JVM of the CAVANWC STC. Find the line "# JVM CONFIGURATION PARAMETERS" in the started task and add the lines:

export IBM_JAVACOREDIR=
export TMPDIR=

The directory configured in IBM_JAVACOREDIR will be the default directory for creating dumps. If for some reason the dump cannot be created there then the dump will be created in the directory specified by the TMPDIR parameter.

Additional Information

To change the HLQ of where the Web Client is storing dump data sets, locate the line "# JVM CONFIGURATION PARAMETERS" in the started task and add the line:

export JAVA_DUMP_TDUMP_PATTERN=<pattern>

By default this pattern is set to:    %uid.JVM.TDUMP.%job.D%y%m%d.T%H%M%S

Here is an example of changing the default pattern: 

export JAVA_DUMP_TDUMP_PATTERN=MYVANTWC.TDUMP.%job.D%y%m%d.T%H%M%S
