Yes, this is a real problem. Many Application users reported the slowness. It is slow.
9 threads in the ABC database and only one is executing and the remaining threads are just waiting.

How long has the process been running
I'm not sure about this. Please tell me how to check this.

I do not see any issues with websphere servers now. But on Database server, i see utilixation
vmstat o/p

Code:

System configuration: lcpu=10 mem=24576MB ent=1.00

mdbFontSize(5)							 The m17n Library						    mdbFontSize(5)

NAME

       mdbFontSize - Font Size

DESCRIPTION

       In some case, a font contains incorrect information about its size (typically in the case of a hacked TrueType font), which results in a
       bad text layout when such a font is used in combination with the other fonts. To overcome this problem, the m17n library loads information
       about font-size adjustment from the m17n database by the tags <font, resize>. The data is loaded as a plist of this format.

       FONT-SIZE-ADJUSTMENT ::= PER-FONT *

       PER-FONT ::= '(' FONT-SPEC ADJUST-RATIO ')'

       FONT-SPEC ::=
	   '(' [ FOUNDRY FAMILY
	      [ WEIGHT [ STYLE [ STRETCH [ ADSTYLE ]]]]]
	    REGISTRY ')'

       ADJUST-RATIO ::= INTEGER

       FONT-SPEC is to specify properties of a font. FOUNDRY to REGISTRY are symbols corresponding to Mfoundry to Mregistry property of a font.
       See m17nFont for the meaning of each property.

       ADJUST-RATIO is an integer number specifying by percentage how much the font-size must be adjusted. For instance, this PER-FONT:

	   ((devanagari-cdac) 150)

       instructs the font handler of the m17n library to open a font of 1.5 times bigger than a requested size on opening a font whose registry is
       'devanagari-cdac'.
