You can use this function to perform the following management tasks for archive stores: define new archive stores, change, delete, or test existing archive stores.
You have called up the XML DAS Administration from within the NetWeaver Administrator (NWA) and have set up the storage system as described under Administration of the XML Data Archiving Service.
If archive stores have already been defined, they are listed in the table. To define a new archive store, proceed as follows:
1. Choose Define.
A new, empty row appears in the archive stores table list.
Enter the following information in the appropriate columns:
○ Archive Store: A name for your new archive store
○ Description: Enter a description for archive store (for example, the name of a file server).
○ Default: Designate an archive store as a default archive store. (This function is necessary for future use, but has no effect at the moment)
○ Store Type: Use the drop down list from the field help to choose the option that corresponds to the storage system you are using. You can choose between WebDAV System and File System.
The following entries vary depending on the information you entered under Store Type. If you entered:
Destination: Use the drop down list of the field help to choose the appropriate archive store root.
The destination must have been created previously in the NWA, in order for it to appear in the drop down list. See Destination Service for more information on how to create destinations. See also the Java Configuration Guide under Configuring the XML Data Archiving Service.
Proxy Host: If applicable, enter the appropriate host if you are using a WebDAV system via a proxy.
Proxy Port: If applicable, enter the appropriate port if you are using a WebDAV system via a proxy.
These entries are optional and only apply if you are using a proxy server. However, if you enter information for one, you must enter information in the other.
Windows Root: If a server running on an operating system of the Windows syntax group belongs to your AS Java, enter the root to the storage system as it is seen from the perspective of the Windows server.
Unix Root: Enter the appropriate root.
If a server running on an operating system of the Unix syntax group belongs to your AS Java cluster, enter the root to the archive store as it is seen from the Unix server.
When defining archive stores it is very important that you choose every archive store according to the following general rules (within the same file or WebDAV system):
1) Two archive stores must not have identical archive store roots.
2) None of the child directories or collections of the archive store root you want to choose for a new archive store may already be used as an archive store root.
3) None of the parent directories or collections of the archive store root you want to choose for a new archive store may already be used as an archive store root.
Figure 1: Possible and Impossible Options for Choosing an Archive Store Root
In Figure 1 you can see that the following root has been defined for archive store X: /a/b/c. Now you want to define a root for archive store Y. Based on the general three rules named above, it would not be possible to use the root /a/b/c for archive store Y, because /a/b/c is already being used by archive store X. It would also not be possible to use the archive store root /a/b/c/d, because it contains an archive store root that has already been used for another archive store. It would, however, be possible to use archive store root /a/b/z, /a/m, or /a/m/n.
○ ILM: This column is informational and shows whether the storage system of a specific archive store has been enabled to meet the SAP Information Lifecycle Management (ILM) archive interface requirements.
○ Status: This column isinformational and shows whether an archive store is running or not. See the testing section below.
2. Choose Ok.
The list of archive stores now contains your newly defined store. Check that the information is correct.
If you want to change the information for an already existing store proceed as follows:
1. Select the row of the archive store you want to change and choose Change.
2. Make the desired changes in the appropriate fields. (You can only access those fields in the list where a change is possible).
3. Choose Ok.
The list of archive stores is now updated.
If you want to delete an archive store proceed as follows:
1. Select the row of the archive store you want to delete and choose Delete.
You can only delete archive stores that have not been used yet in any XML archiving sessions.
The changes you make to archive stores affect the definition of your archive store. Nothing is actually changed or deleted in the file system or WebDAV system.
If you want to test the accessibility and availability of archive stores proceed as follows:
● Select the row of the archive store you want to test and choose Test selected.
The status column shows whether the archive store is currently running or not through the messages Ok or Not ok, respectively.
● Choose Test all to test all archive stores in the list.
The status column shows whether the archive stores are currently running or not through the messages Ok or Not ok, respectively.
