DLP- A552 Adjust the Java Virtual Memory Heap Size

Step 2 View the following TARP data cache information:

•TID—The target identifier of the originating NE. For ONS 15454s, the TID is the name entered in the Node Name/TID field on the Provisioning > General tab.

•NSAP/NET—The Network Service Access Point or Network Element Title of the originating NE.

•Type—Indicates how the TARP data cache entry was created:

–Dynamic—The entry was created through the TARP propagation process.

–Static—The entry was manually created and is a static entry.

Step 3 If you want to query the network for an NSAP that matches a TID, complete the following steps. Otherwise, continue with Step 4.

Note The TID to NSAP function is not available if the TARP data cache is not enabled on the Provisioning > OSI > TARP subtab.

a.Click the TID to NSAP button.

b.In the TID to NSAP dialog box, enter the TID you want to map to an NSAP.

c.Click OK, then click OK on the information message.

d.On the TDC tab, click Refresh.

If TARP finds the TID in its TDC it returns the matching NSAP. If not, TARP sends PDUs across the network. Replies will return to the TDC later, and a check TDC later message is displayed.

Step 4 If you want to delete all the dynamically-generated TDC entries, click the Flush Dynamic Entries button. If not, continue with Step 5.

Step 5 Return to your originating procedure (NTP).
