Configuration of RAM disk for scratch pad usage

[PeteM2]

Problem description
we configured datastage to use RAM disk when using the scratch pad
resource, please see config file below:-

node "node1"
{
fastname "cb17biretlprd"
pools ""
resource disk "/opt/dstransfer/Datasets" {pools ""}
resource scratchdisk "/BIR_RAMDISK" {pools ""}
resource scratchdisk "/opt/dstransfer/Scratch" {pools ""}
}
node "node2"
{
fastname "cb17biretlprd"
pools ""
resource disk "/opt/dstransfer/Datasets" {pools ""}
resource scratchdisk "/BIR_RAMDISK" {pools ""}
resource scratchdisk "/opt/dstransfer/Scratch" {pools ""}
}

We encountered the following error message with some of our jobs that
were performing oracle truncate and load tasks. If the RAM disk became
full we expected the scratch disk to overflow into
"/opt/dstransfer/Scratch"
but it seems this did not happen. Please advise?

What is the total size of your RAM disk ?

[PeteM2]

16 GB

[rohitagarwal15]

with such a low RAM disk space you will face such types of issue. Either get your RAM disk space increased or use some other mount point (SAN mounted) for scratch disk purpose.
