• New ways for backup, recovery and restore of Essbase Block Storage databases – part 2 by Bernhard Kinkel

  - by Alexandra Georgescu

  After discussing in the first part of this article new options in Essbase for the general backup and restore, this second part will deal with the also rather new feature of Transaction Logging and Replay, which was released in version 11.1, enhancing existing restore options. Tip: Transaction logging and replay cannot be used for aggregate storage databases. Please refer to the Oracle Hyperion Enterprise Performance Management System Backup and Recovery Guide (rel. 11.1.2.1). Even if backups are done on a regular, frequent base, subsequent data entries, loads or calculations would not be reflected in a restored database. Activating Transaction Logging could fill that gap and provides you with an option to capture these post-backup transactions for later replay. The following table shows, which are the transactions that could be logged when Transaction Logging is enabled: In order to activate its usage, corresponding statements could be added to the Essbase.cfg file, using the TRANSACTIONLOGLOCATION command. The complete syntax reads: TRANSACTIONLOGLOCATION [ appname [ dbname]] LOGLOCATION NATIVE ?ENABLE | DISABLE Where appname and dbname are optional parameters giving you the chance in combination with the ENABLE or DISABLE command to set Transaction Logging for certain applications or databases or to exclude them from being logged. If only an appname is specified, the setting applies to all databases in that particular application. If appname and dbname are not defined, all applications and databases would be covered. LOGLOCATION specifies the directory to which the log is written, e.g. D:\temp\trlogs. This directory must already exist or needs to be created before using it for log information being written to it. NATIVE is a reserved keyword that shouldn’t be changed. The following example shows how to first enable logging on a more general level for all databases in the application Sample, followed by a disabling statement on a more granular level for only the Basic database in application Sample, hence excluding it from being logged. TRANSACTIONLOGLOCATION Sample Hyperion/trlog/Sample NATIVE ENABLE TRANSACTIONLOGLOCATION Sample Basic Hyperion/trlog/Sample NATIVE DISABLE Tip: After applying changes to the configuration file you must restart the Essbase server in order to initialize the settings. A maybe required replay of logged transactions after restoring a database can be done only by administrators. The following options are available: In Administration Services selecting Replay Transactions on the right-click menu on the database: Here you can select to replay transactions logged after the last replay request was originally executed or after the time of the last restored backup (whichever occurred later) or transactions logged after a specified time. Or you can replay transactions selectively based on a range of sequence IDs, which can be accessed using Display Transactions on the right-click menu on the database: These sequence ID s (0, 1, 2 … 7 in the screenshot below) are assigned to each logged transaction, indicating the order in which the transaction was performed. This helps to ensure the integrity of the restored data after a replay, as the replay of transactions is enforced in the same order in which they were originally performed. So for example a calculation originally run after a data load cannot be replayed before having replayed the data load first. After a transaction is replayed, you can replay only transactions with a greater sequence ID. For example, replaying the transaction with sequence ID of 4 includes all preceding transactions, while afterwards you can only replay transactions with a sequence ID of 5 or greater. Tip: After restoring a database from a backup you should always completely replay all logged transactions, which were executed after the backup, before executing new transactions. But not only the transaction information itself needs to be logged and stored in a specified directory as described above. During transaction logging, Essbase also creates archive copies of data load and rules files in the following default directory: ARBORPATH/app/appname/dbname/Replay These files are then used during the replay of a logged transaction. By default Essbase archives only data load and rules files for client data loads, but in order to specify the type of data to archive when logging transactions you can use the command TRANSACTIONLOGDATALOADARCHIVE as an additional entry in the Essbase.cfg file. The syntax for the statement is: TRANSACTIONLOGDATALOADARCHIVE [appname [dbname]] [OPTION] While to the [appname [dbname]] argument the same applies like before for TRANSACTIONLOGLOCATION, the valid values for the OPTION argument are the following: Make the respective setting for which files copies should be logged, considering from which location transactions are usually taking place. Selecting the NONE option prevents Essbase from saving the respective files and the data load cannot be replayed. In this case you must first manually load the data before you can replay the transactions. Tip: If you use server or SQL data and the data and rules files are not archived in the Replay directory (for example, you did not use the SERVER or SERVER_CLIENT option), Essbase replays the data that is actually in the data source at the moment of the replay, which may or may not be the data that was originally loaded. You can find more detailed information in the following documents: Oracle Hyperion Enterprise Performance Management System Backup and Recovery Guide (rel. 11.1.2.1) Oracle Essbase Online Documentation (rel. 11.1.2.1)) Enterprise Performance Management System Documentation (including previous releases) Or on the Oracle Technology Network.

What are the other changes I need to do?

• Is it possible to change the content database of an existing SharePoint '07 web app?

  - by mcjabberz

  Disclaimer: I'm very much an accidental SharePoint admin so I greatly appreciate your patience. My SharePoint farm's database server is EOL and about to die. I have managed to get the config database (SharePoint_Config) moved over to the new database server and even managed to get the Central Administration site to use the new database server. I have even added the new database server to the farm as a content database server. My problem right now is with the web app's content database (WSS_Content). I already have a copy of the content database setup and ready to go on the new database server but, for the life of me, I can't figure out how to change the SharePoint web app's database over to it. Is this even possible? If so, how would I do it? If not, would I have to create a new web app and then restore (and overwrite) its WSS_Content database with my existing one?

• Backup the Windows user folder in the cloud?

  - by Benjamin

  As I understand it, Google Drive and Dropbox, the two cloud storage providers I happen to know, can only sync a predefined folder that is created upon installation. I'd be happy to have an automated synchronisation of my folders in the cloud, but I'm not ready to change my habits, and start saving all my documents in the folder imposed by the provider. Is it possible with one of these, or any other you might know, to sync the full Windows user folder instead?

• migrating puppet clients to a new puppet master (old puppet master server gone, only using backup)

  - by user47650

  My puppet master server had a hardware failure, and I have restored to another box. However this box has different hardware and hostname. If I restore the existing /etc/puppet directory to the new server, the puppetmaster will not start with the following error; # puppetmasterd --debug --verbose Could not prepare for execution: Retrieved certificate does not match private key; please remove certificate from server and regenerate it with the current key So what steps do I need to take to allow the new puppetmaster to start, and to generate a new puppetmaster certificate using the old ca.. Also will the puppet clients actually report in to a different puppet server using a server certificate that has been generated with the old CA?

• How to backup or export PowerStrip display profiles?

  I would like to save two of my saved PowerStrip display profiles. Earlier I set 720x540 resolution and some other settings (frequency, etc.) to another display device usually used in extended mode, which is now NOT connected: But when I go to "Advanced timing options", I see some different settings. I thought I could copy settings with the copy icon , but this way I would copy the wrong ones, not the predefined ones (with the 720x540 resolution): What is the best method to "export" these settings before formatting the hard drive?
