DISK_STORE_ID

public static final Pattern DISK_STORE_ID

Matches a disk store id, as printed out from list-missing disk stores. The first group is the disk store id, the second group is the host name and the thirds is the port. Here's an example of a disk store id: 8ba7780c-dab8-4f9a-a1cb-fe66ea256650 [dasmith-e6410:/home/dsmith/data/work/manual_test_4/server2/.]

Method Detail

HydraTask_doOfflineValAndCompactionOnce

public static void HydraTask_doOfflineValAndCompactionOnce()

Run the offline validator and compaction tool. This can be called by concurrent threads across multiple jvms, and only 1 thread will do the validate and compaction. If this task is used more than once per test, then prior to invoking this task for the 2nd time (or more) you must first call PersistenceUtil.HydraTask_initialize.

HydraTask_doOfflineExportOnce

public static void HydraTask_doOfflineExportOnce()

Run the offline export command. This can be called by concurrent threads across multiple jvms, and only 1 thread will do the export. If this task is used more than once per test, then prior to invoking this task for the 2nd time (or more) you must first call PersistenceUtil.HydraTask_initialize.

HydraTask_initialize

public static void HydraTask_initialize()

Initialize blackboard. This is used if a test does more than one invocation of HydraTask_doOfflineValAndCompaction

doOfflineValAndCompaction

public static void doOfflineValAndCompaction()

Run the offline validator and compaction tool. This should be called by only 1 thread at a time. If you need to invoke this task with multiple threads (perhaps you don't have a threadGroup with only one thread) see HydraTask_doOfflineValAndCompactionOnce().

getDiskStores

public static Set<String> getDiskStores()

Return a Set of diskStore names in use by the test

doOfflineExport

public static void doOfflineExport()

Run the offline export tool. This should be called by only 1 thread at a time. If you need to invoke this task with multiple threads (perhaps you don't have a threadGroup with only one thread) see HydraTask_doOfflineExport().

runOfflineExport

public static void runOfflineExport(Integer vmid,
                                    String diskStoreName,
                                    File[] diskDirArr)

Run the offline export tool.

Parameters:

diskStoreName - The name of the diskStore to export.

diskDirArr - An Array of disk directories, one of which contains the .if (info) file for diskStoreName.

getDiskDirMap

public static Map<Integer,List<File>> getDiskDirMap()

Return a Map of vmIDs (keys) and disk directories (values)

Returns:

A Map where the key is a Integer (vmID) and the value is a List of Files where each File is a directory of disk files for that vmID

scramble

protected static void scramble(File[] fileArr)

Change the order of the files in the array

Parameters:

fileArr - An Array of Files to change order of.

diskDirsContainInfoFile

public static boolean diskDirsContainInfoFile(List<File> diskDirList,
                                              String diskStoreName)

Return true if the list of disk directories contains an init file (*.if) for the given diskStoreName,return false otherwise.

Parameters:

diskDirList - A list of Files, each one is a directory containing disk files.

diskStoreName - The diskStoreName to check for in the list of directories.

Returns:

true of the list of disk directories contains an init file (*.if) for the given diskStoreName, false otherwise.

runOfflineValAndCompaction

public static void runOfflineValAndCompaction(String diskStoreName,
                                              File[] diskDirArr)

Given a diskStoreName and an array of disk directories: 1) run the offline validator 2) run the offline compactor 3) run the offline validator again then check that the validator returns the same results before and after the compactor.

Parameters:

diskStoreName - The name of a diskStore.

diskDirArr - An array of Files, each element being a disk directory.

runOfflineValidate

public static Object[] runOfflineValidate(String diskStoreName,
                                          File[] diskDirArr)

Run the offline validate tool.

Parameters:

diskStoreName - The name of the diskStore to validate.

diskDirArr - An Array of disk directories, one of which contains the .if (info) file for diskStoreName.

Returns:

[0] The String results from the validator [1] Map with key being a regionName, and value being a Map with key "entryCount" and "bucketCount", values being Integers of the count for this dataStore.

doOnlineBackup

public static void doOnlineBackup(boolean incremental)

Run the online backup command

Parameters:

incremental - set to true to perform an incremental backup.

performCompactionOnBackup - validation and compaction are peformed on the backup directory when true.

runListMissingDiskStores

public static String runListMissingDiskStores()

Using the command line tool, run list-missing-disk-stores

runRevokeMissingDiskStore

public static void runRevokeMissingDiskStore(com.gemstone.gemfire.cache.persistence.PersistentID id)

Using the command line too, run the revokeMissingDiskStore tool.

Parameters:

id - The persistent member to revoke.
