2.4.2.2.5 Troubleshooting

The following are the troubleshooting scenarios for SCPVAL action:

  • If an incoming MSU successfully passes SCPVAL CdPA GTT action, then the VstpCdpaGttActScpvalTotal measurement will be pegged on a per Linkset basis.

  • If validation was not applied by SCPVAL CdPA GTT action on an incoming message, VstpCdpaGttActScpvalNotApplied will be pegged on a per Linkset basis.

  • If incoming MSU is discarded by SCPVAL CdPA GTT action, then VstpCdpaGttActScpvalDiscard measurement will be pegged on a per Linkset basis.

  • If validation was not applied by SCPVAL CgPA GTT action on an incoming message, VstpCgpaGttActScpvalNotApplied will be pegged on a per Linkset basis .

  • If an incoming MSU successfully passes SCPVAL CgPA GTT action , then VstpCgpaGttActScpvalTotal measurement will be pegged on a per Linkset basis.

  • If incoming MSU is discarded by SCPVAL CgPA GTT action, then VstpCgpaGttActScpvalDiscard measurement will be pegged on a per Linkset basis.

  • When anyone of the GTT Action (i.e. DUPLICATE, FORWARD, TCAP ERROR, SCPVAL) fails and UIMREQD is set to ON, then event 70278 GTT Action Failed will be generated. It contains error cause with SCCP and TCAP details, GTT Action set name and linkset ID.

  • If any of the above statement fails as per given scenarios, then verify the configuration. In case the issue persistes, contact Oracle Support.
